Intel Wireless 3160
Faustina Bartsch
I have a Lenovo Z51-70 with an Intel Dual Band wireless-AC 3160 and a Technicolor Modem. The wi-fi keeps disconnecting, or rather, cannot be detected at all after few hours of work. I found some sort of "turn-around solution", that is to say uninstalling the drivers of the network adapter and restart my PC.
I've tried everything, even changing the settings of the adapter (clean driver installation from intel download centre, 2,4 GHz instead of 5; Disabling Bluetooth, changing power settings, Disabling U-APDS, Set other wireless and HT modes, and so on...) but NOTHING seems to work...

Thank a million Scott! You are really kind to share these drivers. I was having exactly the same problem as ZicVan after performing a factory reset on my Dell Inspiron 5548 which has the same wireless adapter, viz. Intel Dual Band wireless-AC 31600. The laptop simply refused to see my Orbi RBR750 router although all newer laptops and handheld devices could easily connect to it. I was at my wits end, searching for a solution on the net until I came across this thread. After installing the WiFi_21.10.1_64_Win10 update, the connection is working perfectly. Once, thanks a lot.
You are welcome. It's too bad that Intel has taken this 'what have you bought from us lately' attitude towards customer support. They blame it on legal repercussions (if it's old, it must have security issues), but I don't buy that at all.

Hi
I am using jetpack 6 on my orin nano 8 gb module, I have intel WLAN card 3160 , however I am unable to see wifi symbol once I login to orin nano ubuntu , I can see bluetooth and able to search for bluetooth devices . But not able to maintain the connection , disconnects moments after it connected.
When I run the command
sudo lshw -C network
I see network UNCLAIMED and configuration not showing any driver, and product : Wireless 3160.
Please help.
I'm in the same boat as some other folks and trying to get as clear an answer as possible before I move forward - I have an HP Envy 15 k220nr that came with the intel 3160 1x1 AC card. I want to upgrade to at least a 2x2, if not a 3x3, AC card to get the fastest possible speeds from my AC1900 router. The safest bet, outside using an external USB 3.0 adapter (which would be bulky and problematic) appears to be installing the Intel 7260 2x2 AC card.
Has anyone done this? Did it install without much trouble? Did it work once installed? Did you see a significant speed difference? Any problems with the new card? Any tips for the install? Were you able to confirm the K220NR has two antenna wires internally to support a 2x2 card (or, and I doubt I'm this lucky, does it have 3 antennas)? Please let us know - I want to upgrade, but want to be sure it will work before ordering everything and completely disassembling the laptop again (I've already done it once to install a 500GB Samsung 850 EVO SSD, and it wasn't a ton of fun).
Also, to you or anyone else paying attention, since I'm going to be opening up the laptop anyway, is there any reason I should NOT upgrade the RAM at the same time? It appears the laptop supports DDR3L 1600 ram; I'm thinking about upgrading from 8GB to 16GB - any problem foreseen with doing this, will any RAM work or is there a whitelist, is there any reason I should avoid it (beyond the RAM being the hardest thing to access when disassembling this model)?
Any help, guidance, info on how it worked for you, things to watch out for, etc... would be much appreciated. I welcome answers to questions I didn't as or thoughts in general about doing this. Thanks!
I purchased the card from Amazon; the specific model is "Intel Network 7260.HMWG.R" - the .R is important as it is revised version of the chip with improvements over the original. This is, per reports from Intel, the same as the card SKU 7260.HMWWB.R - the different SKUs simply represent different packages. Check it out at:
This was a surprisingly simple upgrade. I simply shut down my computer, which was already upgraded to Windows 10 Pro. As with all installs, follow appropriate control measures for static (clean room, wrist band), tracking which screws go where (easier in this case as they're mostly identifcal when disassembling the machine), and general best practices for servicing a system. I would not recommend this upgrade be done by an amateur - this is a more complex install since you have to access the mainboard and disassemble the enclosure rather than simply open an access port on the bottom of the computer. That said, for having to open the base enclosure, this is a very easy process (relatively speaking) with this laptop. It helps that the service manual is very thorough. Be careful, as if you are not an authorized service provider and your computer is under warranty, you could void your warranty by opening the machine. Also, don't foget to keep the old card so you can reinstall it and restore your computer back to factor specs if you need to send it in for warranty service or want to sell it but keep the newer card.
It took my about 20 minutes to disassemble, install, test, and reassemble. BEFORE YOU START, download the new drivers you'll need - the HP drivers are working great, and I always go with current manufacturer drivers over the OEM drivers when possible as they're often optimized for the system. You can also download the drivers from download.intel.com, but I would recommend getting the current network wireless WLAN driver from the HP download page ( -en/drivers/selfservice/HP-ENVY-15-Notebook-PC-series/7527530/model/7685078#...). For this card, you want the same drivers as for the AC-3160 card as they use the same drivers. Download BOTH the WLAN and Bluetooth drivers - as of this writing the drivers were updated 10/15/15 and are:
After downloading the drivers, put them on your desktop or somewhere else easy to access as you'll need them as soon as you reboot following the install, and the wireless will NOT work initially, so if you don't have the drivers you'll gave to get them with a wired connection or from another computer.
I disassembled the machine per the Service Manual ( ). Remove the battery and the base enclosure, disconnect the ribbon cables for the keyboard, mouse and fingerprint sensor, and flip up the base cover and rest it against the monitor. BE CAREFUL - this shifts the computer's center of gravity, and makes the computer want to tip over backward as I learned when I caught mine from flipping back off the table I was working on - just be careful.
After you open up the enclosure, installation is incredibly simple. The WLAN card is located in the back of the computer near the middle - back where the monitor hinges connect to the computer, centered between them. You simply pop off the two wireless antennas (YES - this laptop, despite shipping with only 1x1 AC Wireless Card options, DOES HAVE two factory installed antenna, so it can fully support a 2x2 card), and then remove the screw holding the card in place. The card will pop up; slide it back (small fingers help - I have big hands and this was tricky since the card is pressed up against the back of the case) and pop it out. Insert the new card, press it down, screw it in, and reattach the antennas, making sure the wire connected to "Main" on the original card is connected to "Main" on the new card, and the "AUX" wire is connected to "AUX". On my computer the black wire was the main antenna, the grey wire was the second antenna.
If you're like me, after you install, you may want to set reconnect the keyboard/mouse/finger print sensor and reboot the machine before screwing everything back together to be sure it works. Just be careful if you do this. When you restart, wireless will not be working. Run the installers for the drivers you downloaded at the beginning - I found installing the wireless dirver and then the bluetooth driver worked best. After they install and you restart, everything should be working great, including bluetooth. I had absolutely no issues with getting everything to work.
Now the funnest part: performance. The card is hands-down incredibly faster then the stock card. The 2x2 MIMO streams virtually double your upload/download performance (assuming you have at least at AC1200 router that supports the speeds the card does). I use an ASUS AC1900 RT-AC68U, an awesome router worth every penny. From speedtest.net, my laptop on wireless now easily keeps up with my 60MBPS internet service, going just as fast as my wired connection (with the old card, it maxed out for download around 50MBPS; with the new card, it uses the full bandwidth, closer to 70MBPS for us. Upload speeds were around 4.5-5MBPS, to be expected given our internet service.
File transfers are literally about twice as fast as prior to the upgrade. I've maintained sustained actual download speeds of over 8 MB/s when about 40 feet from the router with 3 walls and some other items in the way. File transfer speeds are great, getting over 40MBPS transferring files to my NAS, compared to closer to 20 with the original card (also from 40 feet with 3 walls and other obstacles).
