Intel Wireless-AC 7260 often disconnecting

Postby dafalk » Sun Feb 01, 2015 8:06 am

Hello Mint Community!

At first: I like Linux Mint a lot. It makes my linux life easy! And my work as a webdeveloper I can do very well with this linux.

I am using my Lenovo t440s (20AQ0069GE) since a few month with Linux Mint 17. Besides I had some troubles with f.e. keyboard layout (print button didn't work), the brightness keys are not working properly, restarting from sleep modus needs about 1 Minute and some other small things, the main and really annoying problems I have, is with my wireless card Intel Wireless-AC 7260.

It sometimes does not connect to WLAN or needs 10 or more times to be successfull. If it is connected, after a while the WLAN speed becomes slower and I have to reconnect to WLAN, if possible. It does not depend on which WLAN (home, friends, office).

Or other situation: I am at home, working. then I got to sleep modus. When I wake up the notbook on another place, it stays "connected" with my home WLAN (even I am not at home anymore), instead to connect to the new found WLAN. I have to do this manually.

I read a few month ago about problems like these with this WLAN Card. Is there meanwhile a known good solution for this Card?

Best!
Falk

Since it is a new type of wireless card, it may be worth using an updated driver.

Please download this driver package: http://www.kernel.org/pub/linux/kernel/ ... 1-1.tar.xz

After extracting the archive (it works like a ZIP file), go to the folder where you extracted it. Inside that folder please right-click in the empty space > Open in Terminal.
In that terminal, please run these commands:

Code: Select all

make defconfig-wifi
make
sudo make install

That will install updated versions of the preinstalled wireless drivers.

There are a few things to try
#1

Code: Select all

echo "options iwlwifi 11n_disable=8" | sudo tee /etc/modprobe.d/iwlwifi2.conf
Reboot
#2

Code: Select all

iw reg get
does it match the country you are in? If not, what country are you in?

Thanks. I installed the recommended driver. I'll see if it helps.

iw reg get gives no country, just:

country 00:
(2402 - 2472 @ 40), (3, 20)
(2457 - 2482 @ 40), (3, 20), PASSIVE-SCAN, NO-IBSS
(2474 - 2494 @ 20), (3, 20), NO-OFDM, PASSIVE-SCAN, NO-IBSS
(5170 - 5250 @ 40), (3, 20), PASSIVE-SCAN, NO-IBSS
(5735 - 5835 @ 40), (3, 20), PASSIVE-SCAN, NO-IBSS


what have I done with:
echo "options iwlwifi 11n_disable=8" | sudo tee /etc/modprobe.d/iwlwifi2.conf

That command actually enable agg tx for the iwlwifi driver, it should speed up the connection, see bug report https://bugs.launchpad.net/ubuntu/+sour ... ug/1319630 see comment 11

What country are you in, so we can run a command to get it set

Ok so

Code: Select all

sudo iw reg set DE
and we will set it in another file for good measure

Code: Select all

sudo sed -i 's/^REG.*=$/&DE/' /etc/default/crda


You can check to see if the second command worked with

Code: Select all

cat /etc/default/crda
the very last line should read
REGDOMAIN=DE

Reboot

I would like to buy this card to replace the Ralink RT3290 (bluetooth not supported).
If i update the drive in this easy way:

https://wireless.wiki.kernel.org/en/use ... rs/iwlwifi

Isn't it the same thing?
How does bluetooth work?

You shouldn't have to download anything after installing a 7260 card in LM 17 or newer
