do you mean a router
or as part of the laptop spec ?

what router do you have and does it work in dual band simultaneously

the advantage of the 5ghz signal is if you are in a crowded 2.4ghz environment then 5ghz helps avoid interference - also the coverage is wider - although the 5ghz router i have linksys - does not seem to be

if your current router only works in 2.4ghz , then no advantage in the short term

some routers are advertised as dual band - but you have to choose between 2.4 or 5 ghz and so ALL devices will need to support 5ghz

I'm having problems with my pavilion 17-G192DX.  when I have the wifi on, it works for about 10 minutes, then basically shuts down my home network - TV locks up, no other computers can access the internet.  As soon as I turn the wifi off, everything goes back to normal.  HP troubleshooting can find nothing...when the thing is working, that is.  I'd like to upgradethe wifi card with a dual band unit?  I'm thinking the Intel 7260 2x2.  Will that work in this computer?  Any other options?  P/N is V0Q01UA.

Yes you can install any wireless card of the right form factor which for your laptop is an M.2 adapter. See the Manual here: http://h10032.www1.hp.com/ctg/Manual/c04655191 The 7260ac is a mini-pcie card and is not compatible but you could MAYBE install an Intel 8260ac card: https://www.amazon.com/Wireless-8260AC-8260NGW-Bluetooth-Wireless/dp/B01ERMBDCK/ref=sr_1_2?ie=UTF8&q... Start on p. 31 with removal of the back cover and read through p. 39. The hesitation is that, to install a dual band card you must have 2 antennae and on some HP models with lower-end wireless cards there is only one. So if you want to do this I recommend open it first and count antennae. If two, you can install the card linked above, which will perform as well as any wireless card you can buy.  Let us know if there are other questions.  If this is "the Answer" please click "Accept as SOlution" to help others find it.

It has stock 2.4ghz wifi, which i know is pretty standard.

Hi: Below is the link to the service manual for your notebook. http://h10032.www1.hp.com/ctg/Manual/c03593667 Unfortunately the 3 supported wireless cards listed in chapter 3 are all single band cards. Back when your notebook was produced, HP had a BIOS whitelist which prevents any other wlan card from working other than the ones listed in the service manual.

Hi,
Just purchased a 13" Inspiron 5000, got it set up, things are going fine. Then I do a speed test on wifi. As background, I have 1gbps broadband with an Ubee cable modem/router that supports AC protocol. I have a 3 year old Lenovo laptop with an Intel DB 7260ac that pulls in 300-400mbps. I also have a 5 year old MacBook Pro with airport extreme b/G/n card that pulls in 250mbps. The new Inspiron only gets 150mbps.
I've been trying to figure out why. The 3165ac card in the Dell has a theoretical max of 433mbps. That's already disappointing, since gigabit broadband is now available. But working with that, I have the Ubee router set to N/AC only protocols, using 5Ghz, wmm on, 80Mhz bandwidth, SSID set. It seems like it should agree with the 3165ac card to negotiate the fastest speed, but it seems like I'm only getting half N speeds.
I have the latest Intel drivers, windows fully updated, removed all bloatware. All speed tests (ookla, Google fiber, Xfinity, etc) are consistent. Is this a limitation of the wifi card? Of note, I see the 3165ac is a 1x1 card. My Lenovo has a 2x2 card. I just makes no sense that my newest laptop has the slowest speed.

A:Brand new 13" Inspiron 5000 wifi capped at 150mbps (dual band 3165ac)

The 1x1 antenna design is the culprit.  The AC7260 remains a great 2x2 card even today, and the AirPort Extreme card is probably 3x3 since it's 802.11n (it's rare to see 3x3 AC devices other than routers). Extra antennas allows multiple simultaneous data streams, which can significantly increase maximum real-world throughput.The fact that the 3165 is rated for "up to" 433 Mbps is pretty meaningless in the real world, just like every other WiFi speed quoted in marketing materials.  The AC7260 is rated for 867 Mbps, for example, and clearly you're not getting that level of performance out of it either, although in fairness, the only WiFi ROUTERS that can push that kind of bandwidth in the real world to begin with are very recent 4x4 802.11ac routers (like my ASUS RT-AC88U), and then only when acting as a media bridge to another 4x4 802.11ac router. There aren't any 4x4 AC clients to handle that, so making the most of gigabit Internet still requires a wired connection for now.Anyhow, if you're comfortable opening up your system, you can see whether there's an extra antenna already in the chassis (its connector would probably have a plastic sleeve around it since that card can't use it), in which case you could buy something like an Intel 8265 for ~$30 (in the US) from Amazon/eBay, which is their latest and greatest 2x2 AC card.  If you only have a single antenna in the chassis, then you may be stuck.  You MIGHT be able to...

Yes it is new enough not to have the whitelist so you can install any wireless card with the right form factor.  Here is the Service Manual: Manual See p. 45. HP offered this one which is the top of the line: Intel Dual Band Wireless-AC 7260 802.11 ac 2x2 WiFi + Intel Dual Band Wireless-AC 7260 BT 4.0 combo adapter 756753-001 Available on Amazon.com: https://www.amazon.com/710661-001-Intel-Wireless-ac-7260-Pci-express/dp/B00PDLCFL8/ref=sr_1_1?ie=UTF8&qid=1470826413&sr=8-1&keywords=756753-001 This is a drop-in plug and play replacement. You would want to get the driver files on the hard drive (like maybe the desktop) and have them available before you make the swap to be sure the card will work once you reboot Windows.

I'm trying to help save a neighbor some money by fixing their wireless network.

WNDR3700 Dual band Netgear router.

2.4ghz wireless b/g/n with enabled SSID broadcast, channel=auto, mode set to 130Mbps
WPA-TKIP + WPA2-AES. wireless isolation is not enabled.

5Ghz wireless a/n enabled SSID broadcast, channel = 44, Mode is up to 300Mbps
No security encription. (i know...bad, but the lady has lots of kids and family members coming
and going from the house so she doesn't want one encripted). Video network enabled

Both Radio frequencies are enabled, fragment and CTS/RTS set to max

WPS settings = keep existing.

IPv6 not enabled, No repeating is enabled, No guest networks are enabled(however ssid broadcast is enabled for guest profile 1)
The problem, and reason for fixing the problem is that the 2.4 Ghz band light on the router is ON however the SSID is not being seen by any client in the house. the netgear interface says it is on and working. the neighbor needs the 2.4ghz band to work because the printer is wireless and will only recognize 2.4Ghz SSIDs. Also they have older nintendo DS clients they would like to use on the network.

During the day the 5 Ghz band works with very seldom (1-2) disconnects while the 2.4 Ghz band wont be visible to any device. in the evening both bands will come online, and very often will every computer get disconnected from either, the 5Ghz band wi... Read more

Hi there!

So about 2 months ago, I purchased the AC53 when I moved in to a house share.
We have Virgin Media SuperHub that does both 2.4ghz and 5ghz.
When I installed it, it worked fine and connected excellently to the 5G band, a few days ago however the 5G connection disappeared off my list and now it always connects me to the 2.4ghz band.

Tried resetting my SuperHub and re-installing the drivers and software utility for the AC53 but alas it doesn't show. My phone however can find and connect to the 5G band.

I'm a bit confused as where to go from here!

Any help would be much appreciated!

After re-installing you can't connect at all or just only connect to 2.4?

Can you run ipconfig /all and post back the results.
Click Start, in the search box type cmd, under programs right click on cmd and select "Run as Administrator".
In the command prompt window type ipconfig /all and press enter.
Next right click within the command prompt and select "Select All" press enter.
Paste the results back in this thread.

I need a recommendation for a internal Dual band wireless network card replacement for an HP Probook 4540s

A:Dual Band Wireless card for HP Probook 4540s

Hi: Your notebook has a BIOS whitelist which prevents the installation of any wireless card other than those listed in the service manual. They must also have the HP part number on the card or they will not work. Looking a chapter 3, page 29, the only dual band wlan card option there is would be theIntel Centrino Advanced-N 6235, with bluetooth.         HP Part # 670292-001 http://h20628.www2.hp.com/km-ext/kmcsdirect/emr_na-c03758231-1.pdf I would check eBay for used but tested and working cards.  Query by the part number, and only buy a wlan card where you see the part number clearly listed in the photograph. It will usually be on a white sticker 'Replace with HP Spare..."

Hey guys and girls. First post in the forum here I'm about to upgrade some parts on my Pav G6 1344sa, namely replace the HDD with a SSD and replace the DVD drive with the HDD, replace the tired keyboard for a new one and upgrade the wifi card for a 5G dual band so i can untilize the speed of my newly installed fibre broadband. After a bit of research i have read there maybe issues getting the Intel AC 7260 card i just ordered to work in this notebook. Can anyone confirm if it will work? I read that some users have used a tweak of covering pin 20 and/or pin 51 with tape to make it compatible, anyone tried this or can explain how this works? Cheers

A:Intel AC 7260 Dual band wi-fi card compatibility

No it will not work and the covering of the pins is actually a Lenovo trick that I have never seen anybody recommend for an HP. I would think it will not work since the problem is a whitelist. The card has to prove to the BIOS what it is, not hide what it is from the BIOS so stopping the identification data from being read will just cause the wifi card to be rejected by the BIOS. As stated, there is a BIOS whitelist and only the specific HP branded wifi cards originally offered with the laptop will pass and allow the system to boot past BIOS. If you want that list just post back.

N600 Wireless Dual Band Router WNDR3400.

I am trying to get a signal out in my garage at the opposite end of my router location. I am getting 1 bar and "poor" signal. I downloaded inSSIDer to analyse my signal and I notice that my "Wireless Network (5GHz a/n)" is not broadcasting anything. The checkbox for "Enable SSID Broadcast" is checked.

I have very limited knowledge of this stuff but it seems to me that if it is a dual band that I should be seeing 2 different signals, right?

All I see is this: Wireless Network (2.4GHz b/g/n)

I have attached screenshot of my settings

Can someone help me out with this? Thanks, Joe
