Wifi drops when I connect to an external monitor

Q: Wifi drops when I connect to an external monitor

I bought my Lenovo Yoga 900S a while back and totally love it, no complaints. Then I received my LG 22M38A monitor this lunchtime and the fun began... I have a VGA to USB adapter, and every time I connect to the laptop my wifi disappears. And I don't meant that it just drops and I have to reconnect, it even disappears completely from the available networks. It's not my broadband - that still works on other devices. It's not even the monitor, as I can plug that in direct with the VGA cable to another, older laptop we have in the house. I tried uninstalling and reinstalling the wireless device drivers but that didn't seem to help (but I did notice that when I connect the monitor the Device Manager seems to flicker, as if it's running a new hardware scan). Does anyone have any ideas? It's driving me totally nuts. I don't know if I should just try buying a replacement adapter, or returning the whole monitor :-( ThanksA

Preferred Solution: Wifi drops when I connect to an external monitor

I recommend downloading and running DAP. It can help sort out any driver and firmware related issues on your system

It's worked out well for many of us in the past.

You can download it direct from this link http://downloaddap.org. (This link will open the download page of DAP so you can save a copy to your computer.)


My wifi goes in and out alot. It's happens on multiple phone, labtops, and a gaming system. So, I feel it's specific to my router not my computers. I want something I can prove to my provider that my wifi keeps dropping. I have Time Warner Cable. Modem information is
Cable Modem Information
Cable Modem : DOCSIS 3.0 Compliant
Boot Code Version : 14.3.1e
Software Version : 8.14.3105
Hardware Version : 3.13.1
CA Key : Installed

The computer I will be running on is windows 8. I don't have net3.5 on my computer.

If my computer is not right next to the router and is idle for a while, the wifi connection drops. I have to "Open Network & Sharing Center", "Change adapter settings", disable and re-enable to reconnect. It's not a router issue since all other devices connect just fine.

A:Wifi drops - have to disable then re-enable to connect

Hi: The only suggestion I can offer would be to see if unchecking the 'Allow the computer to turn off this device to save power' box on the Power Management tab for the wireless card in the device manager, resolves the problem.

Hi,  I use my hp8530p with a docking station and a 21" CRT monitor. The monitor is connected through 15 pin D-SUB VGA connector. When the monitor is connected the WiFi speed drops from 16-20Mbit/s to 1-3Mbit/s according to http://www.speedtest.net/ . The same happens if the docking station is left out of the system and the monitor is directly connected to the laptop.  Does anyone know the solution?  Thanks,Csaba

I hope the title made a little sense.

We currently have 5 - 20 laptops on location depending on the day. There are around 10 signals in the area including our two, which isn't insane considering 15+ signals in an apt building isn't unusual and rarely causes conflict. This is in a two story office building with ours on the top floor. Directly below us is a restaurant which I assume some of their appliances mess with our signal. Regardless of that, we still have great signal strength. We have two routers in the office to help ensure signal strength and two SSIDs (for the swapping mentioned below).

A random number laptops at random times of the day will lose connection to our signals. Which laptop, when, how many laptops, and which SSID is not consistent. There is nothing wrong on the WiFi icon or an ipconfig [/all] and others will still be working on the network just fine. You can then swap to the other SSID, which could at the current time have users working on it and users with it broken, and your internet works. I've tried to find some sort of pattern behind this. Time, brand, model (laptop and WiFi card), nothing leads to a pattern. No where in our office is the signal weak.

Sometimes we do remote conferences/presentation from our location and it looks quite bad when the laptop presenting the remote session randomly drops in the middle of it, so it's becoming quite an issue there. It of course is a nuisance regardless of what people are using the internet for. Any sugges... Read more

Just to clarify some terminology...

APs (i.e. "access points") are more often referred to "wireless access points", i.e. WAPs.

They are not in fact "routers". They are simply "wireless access points", which provide secondary wireless networks (i.e. SSID's) at remote distant locations away from the primary router, through a wired connection to the true primary wired router. This solution is commonly used when the wireless network available from the true primary router just can't reach the remote location dependably because of walls, distance or other radio frequency interference in the neighborhood.

Any device connecting (either wireless, or even wired if the WAP also provides some wired connectors as part of its "wired/wireless switch" technology) through these secondary wireless networks is actually passed on through by the AP to the primary router, where true network connected device management and DHCP occurs. Devices connecting to the WAP (either wired or wireless, doesn't matter) all appear as "wired connected devices" back on the primary router. This is because the WAP really is a "wired multi-port switch" from the perspective of the primary router, and any device connected through a wired switch will app... Read more

I have a Dell XPS 13 laptop running Windows 10. I have just purchased a Dell U2515H monitor which I am waiting for delivery for as we speak. I believe the monitor has quiet a few inputs however I am not 100% sure which lead to get to connect them both and which port I use on the Dell Laptop. Looking on the left hand side of my laptop there is a port with a lightning sign next to it, is that called Thunderbolt? and is that my monitor/display port? and what lead do I need? it looks like some sort of micro socket!

I am using HP 840 G3 and I have connected my LG 29UM58 monitor using a HDMI to Displayport adapter because the ;laptop doesnt have an HDMI port. Funny thing is that if I connect monitor wifi starts dropping packets and performs very slow, once monitor is detached it works fine. I have seen other posts too on internet where people complain about simillar thing with laptops of different brands. The monitor doesnt have any wifi connection so its not a problem with interference, when I unplugged the displayport the monitor was still powred ON and performance became fine which again means its not related to any inteferance . Do you know what problem can this be?

I have a similar problem on my brand new Tecra S11-11G. The only difference is that the problem is only present when I have my laptop plugged-in and the WiFi radio turned on.

If I turn the Wifi radio off and keep the laptop connected to the mains power source, the external display stops flickering. If I keep the WiFi radio on and disconnect the mains power source the flickering also stops.

I reported this problem to the Toshiba customer care in Portugal (where I bought it) and they gave me the ticket Case#710008193. They said they wouldn't replace the defective unit and that I had to leave it for repair. This is absolutely unbelievable since the laptop is brand new. A customer always expects to have a well working product when it takes it out of the box without having to call the repair man. I think it is their obligation to replace the damaged unit. Moreover this laptop is part of a fleet of a company that only buys Toshiba laptops and we are talking about a Tecra and not a Satellite. We deserved more respect from Toshiba.

In a year or so I will have a brand new laptop (company policy) and it surely won't be a Toshiba.

A:Tecra S11-11G - external monitor flickers when Wifi is ON

> They said they wouldn't replace the defective unit and that I had to leave it for repair. This is absolutely unbelievable since the laptop is brand new

Why this is unbelievable? An hardware malfunction can happen always and this does not happen only in the computer/notebook world. Therefore the manufacturers provide a service to a customer and malfunction can be fixed and covered by warranty.

>A customer always expects to have a well working product when it takes it out of the box without having to call the repair man. I think it is their obligation to replace the damaged unit

Of course and you are right but in the real world such things happens.
My PS3 was dead after a short time. It was fixed and replaced under warranty conditions? but this is not a reason for me to say; I would not buy PS3 anymore because of this issue.
My BMW has had some engine problems? it was fixed by warranty and I would buy this car again because this car is great and in my opinion other car manufacturers are not better and I think this would happen to other manufacturers too?

That?s my opinion personal opinion?

This is for a work computer, that I'm 99% sure someone with monkey hands messed up. Now I'm stuck trying to get it fixed.

When I try connecting to a wifi network, the computer attempts to connect for half a beat, and tells me that windows was unable to connect to the network.

I turned off the firewall, there isnt a virus scanner running, and I updated the internal wifi drivers. I even tried using my external USB wifi adapter.

I was able to tether his cell phone to the computer briefly. As far as I knew, he was able to connect that way. He just told me today that the tethered connection doesn't always work,

So whatever is going on, I assume has something to do with a windows software setting. Any ideas?

I can't do a system restore because there is some proprietary software installed that would take an act of congress to get reinstalled.

I have had a Yoga 2.13 for 2.5 years and have, in the past, connected to a couple of 24" monitors using the HDMI port and cable.   For the past three months, I was on the road and never used an external monitor.  Now, I try to connect to a monitor that I used before, with a cable I used before and the monitor does not detect a signal. I have tried another monitor with the same cable. Still get the messsage "no signal detected". I have switched to two other cables - same issue. I have updated the Intel graphics driver, etc. I have spent several hours updating various drivers, etc. I suspect one of two things: 1. I may have upgraded to Windows 10 in the last three months and that is the cause of the problem. 2.  The micro/mini HDMI port on the Yoga is dead. Any ideas on what to do next?

Hello,OK I've just bought a Lenovo Yoga 700 laptop.  Looks great and the reviews are good.My previous (clapped out) Samsung netpad was connected to an external Dell monitor using a cable with what I think is called a VGA connection at both ends. What's the simplest / cheapest way of connecting the monitor to the Yoga?   I seem to need a micro HDMI connection for the Yoga.  Is there any alternative to a new cable - they look pricey when I did a search.

I have an Acer Aspire 2920Z. I have been connecting it to a Samsung Syncmaster 2333t external monitor using a VGA lead and it has been working fine for about a year. Today, it stopped working. At first when I connected the VGA lead, I got a message "Multiscreen application error monitor not found". Then a 'check signal cable' floating box appeared on the Samsung screen.

Now when I try to plug the VGA lead into my laptop, my laptop screen goes black.

Any advice would be greatly appreciated. Thanks in advance.

We got two new Dell XPS 13 for users and there does not seem to be any video out ports like on previous models.  This runs Windows 10 Professional and has an internal screen resolution of 1920x1080.  Looks like there is 2 USB 3.0 super speed ports and possibly a (thunderbolt)??? port?
I've heard of USB-C so I'm not sure if this one port on the left side is that, or if its thunderbolt.  I googled thunderbolt to hdmi adapter and in all the images I find it always shows a mini display port on one end despite the descriptions saying thunderbolt.

So whats the cheapest way to get HDMI out on this laptop?

A:How do I connect an external monitor to a new Dell XPS 13?

The Thunderbolt( USB Type C port) on the Left Hand side deals with the video output on the system. You will need to purchase a USB Type C to HDMI adapter to display video.
The cable is available on the Dell website here

Hey. I have a Windows Vista and recently I had alittle accident where my laptop fell from my bed so this caused the screen to crack. I got a new monitor (a dcl lcd monitor) and when I first got it, it would only let me veiw the external monitor via safe mode. One day I was messing with it and I actually got the monitor to work in normal windows mode. It worked for about a week but one day, I forgot to plug my laptop back in so it ran out of battery and ever since, I have not been able to get it to work in normal windows mode. I have tried starting it normally and pressing Fn + F5 and nothing happens (that I can see because my laptop screen lights up when in Windows mode but the screen is so cracked, I cannot see a thing)..i've also tried going into windows normally and pressing the windows button+X to bring up the "mobility center" but as I said previously, I cannot see anything. I've tried going into the mobility center via safe mode but it does not let me do ANYTHING in safe mode with minor exceptions of being able to go online to try and figure this out. I'm thankful for any help anyone can give me. Thank you! :)

Hi there, I have seen some posts on internet, concerning connecting an external CRT Monitor with a Laptop computer. They pretty much said that there might be a blue cable with, and one can use it to connect that monitor with laptop. Now I am confused that mine monitor has two cables; one of which is blue and the other one is white, having three larger pins inside. Both these wires are connected to my desktop CPU. Now my question is that, it is obvious that the blue wire can be connected to my laptop but what about the other one, this wire is connected to the power supply of my desktop pc, and when it comes to laptop, would mere one wire (blue) suffice for the electricity or other things? Thank you for reading, waiting for your replies. Thanks!

I've been trying for hours to get my Lenovo Thinkpad notebook to connect to the monitor I use for my home computer. I have unplugged the cable in the computer and connected it to my notebook as I usually do to duplicate the screen across two monitors... Only this time it hasn't worked.
The main reason why I want to do this is because my notebook display looks stretched on the notebook screen but when I connect it to the external monitor it always goes normal. This is something that also doesn't want to change no matter what resolution the screen is or however many Google suggestions I read. Any help?
My notebook isn't registering that I have connected the monitor. I have tried changing it from PC to AV and back again, pressing Fn+F7 simultaneously which usually does the trick, and I also tried pressing the windows button on the keypad and 'P' simultaneously but the mouse only briefly shows an hourglass next to it then nothing happens!!
In the setting 'connect to an external display' it doesn't detect that there is an external monitor plugged in. If anyone knows any miracle tricks I would really love for their advice!
Thanks for any suggestions.

I have a Yoga 11s that started having hdmi connection issues about a year ago and has recently quit connecting to an external monitor via HDMI completely. We tried upgrading to Windows 10 to see if that would overwrite any software issues - no luck. The HDMI port actually appears loose. I did an extensive search of the forum and found posts that recommended cutting down the rubber around the base of the hdmi cord - tried that and at least I had a little activitiy - in the upper right hand corner of the external monitor up popped a box that says DVI then VGA then HDMI - but then says No Signal. Tried the graphics card update recommended on a post from long time ago and a popup indicated I had a newer version already installed. I have taken it to a laptop repair place - said they couldn't get parts from Lenovo. I found an "authorized" Lenovo repair shop locally - when I called they said they only work on business machines Called Lenovo and they told me to take it to Best Buy - however since I purchased this directly from Lenovo, Best Buy said they can't work on it. I would rather not send it into Lenovo because they tried to charge my hubby hundreds of dollars when his 15 day brand new laptop quit working, claiming damage - luckily extensive pictures taken and dated prior to sending it in thwarted that attempt at extortion. Does anyone have any suggestions?

Dear all,

I am encountering the following problem and would very much appreciate your help with it: I am using an somewhat dated IBM ThinkPad (R50e), which I'd like to run with an external monitor.

Now, I have connected the monitor (Fujitsu Siemens Scenicview A19-3A) to the external monitor connector using a DVI - VGA/SVGA/XVGA monitor adapter. I have then switched the display output location to "LCD & external (CRT) monitor" using the Fn+F7 key combination, but the external monitor seems not to receive a signal (at least none that he'd be willing to transform into some type of display) -- it remains all black.

I also installed the monitor device drivers from Fujitsu on my laptop, but to no avail.

Any suggestions on what the problem might be and how I might be able to get the external monitor to work with my laptop?

Thanks a lot in advance!


A:How to connect external LCD monitor to laptop (IBM ThinkPad R50e)?

You just need to push the plug in securely (even tighten the thumb screws, if it has any)
Then turn on

It should default to the external, straight away
If not use the Fn+F7 keys as you said (note: I haven't downloaded your manual to confirm this)

By the way, the monitor works normally, and all, doesn't it ?

My lower palmrest and lower buttons were removed before this happened- could this be a cause? I already tried all the Display things and everything, but it doesn't work.

Are you using the correct DVI cable (there are several configurations of DVI connectors).
See this: All About DVI

Also, avoid the use of a VGA-to-DVI adaptor -- they are very unreliable.

I need to setup my laptop Toshiba U945-S4110 to be connected to the VGA input of a monitor display.
What do I need?

Is it enough for this HDMI to VGA active converter

then a VGA to VGA cable

> What do I need?

Well, the notebook supports only the HDMI out port. This port sends the digital video and audio signal.

In case your external monitor supports only the RGB-in (VGA) port, you would need to use some kind of adapter/converter which would be able to convert the HDMI digital signal to VGA analogue signal.

I don?t know if the adaptor would work but you will not get the sound because VGA does not support the audio signal, only video.

Hello there if your reading this thread,
Recently I got my old laptop out of my loft and it had a broken screen but working perfectly before. Today I tried to connecting it to a external monitor via hdmi and it didn't work and I tried vga as well and it didn't work. I wanted it by HDMi because it's high definition, I need some help trying to connect it to the monitor. I tried connecting it to other monitors however it still didn't work. This is the first time I attempt to connect this laptop to a monitor. The model name is Satellite C50D-B-120.
If you have a solution please comment it here or (I'm sorry to waste your time) contact me on Skype : matinadams123

Hi Dell Community,
Please help me to diagnose what is wrong with my new laptop.
My Laptop is Dell Latitude E6440 but every time i connect external monitor to my laptop HDMI port via HDMI to VGA converter, the external monitor always blink randomly every couple of seconds. This HDMI to VGA converter is working fine when i used it to other laptop.
Currently i still don't have chance to try my laptop HDMI port to connect directly to HDMI monitor because i don't have it.
Are there anybody have the same problem with me? thanks for your help.

About a week ago, our cable internet connection went out. Before I had a chance to reboot the modem & router, my 11 year old decided to completely reset the router to factory settings! Ugh! This caused several issues: my home network is now gone, only a unsecured factory network is available. When I try to plug my laptop into the router via ethernet cord (in order to login to router and setup secure network) my computer will not recognize the router and won't connect to internet. I tried troubleshooting with my cable provider and they say it's in my computer (IP address will not reset) and he recommended I replace my network card. However, today when I brought my laptop to work, it will instantly recognize the wifi at work. So is it really my network card that is causing issues? Please help, I'm desperate and not tech too tech savvy!

Hi all,

Got a bit of a weird issue here. I've owned my WAG54GX2 for about... 2 years maybe, and I've got no complaints all round. My usage hasnt changed nor any settings within this period.

However... Over the last week, for some reason the WiFi Connection gets destroyed. I've only seen it once at the point where the Wifi Light goes out (something i've never seen before) - but generally the 2 WiFi conencted PC's fail to keep the connection, they drop out, and fail to get an IP, and when they do manage to get 'on' the connection is terrible. In the mean time, I run wired on 2 boxes that have no noticeable issues at all. Its like the WiFi just gets totally jammed up.

I've tried my hardest to establish what has changed, what is new, whats different at night, and theres just nothing.

Turning off the router and back on seems to have no effect either.

I've attached some logs, I dont know what 99% of it means. But thought maybe someone here could shed some info by translating them.

the Anisdktool seems to be started a lot? normal?

and wns msg tcvd: no idea what thats all about?

ring full looks a bit "** alerting***" but no idea what this is telling me either.

This is super frustrating any insight would be great.
