Intel Wireless 7265 Issues

Postby InfidelCastro » 2019-01-11 19:48

Hello everyone,

This is my first post on the forums. I am experiencing problems with the Intel Wireless 7265 chip on a Thinkpad T450 laptop. I have the latest version of Debian installed and no updates seem to be available through APT. My WiFi keeps disconnecting and reconnecting (about 3 seconds interval) and it is driving me crazy.

The firmware in use is this: firmware=22.391740.0
The driver is this: driver=iwlwifi

Taking a look at dmesg output grepping for iwlwifi returns the following:

[  941.689076] iwlwifi 0000:03:00.0: RF_KILL bit toggled to enable radio.


This dmesg output happens constantly and it seems to be the cause of the issue, but I cannot pinpoint exactly why this happens.

Do you have any idea what might be the culprit of this? Thank you in advance.

Kind regards,

Disable power saving.

We have a thread specifically about iwlwifi, search for it.

It can be really frustrating. I spent four or five days trying all the different combinations of parameters, rfkill/etc on an HP Elitebook using an older 5100 intel wireless device....

My solution was disable bluetooth in bios. Also, the router I have at home does not function correctly when wireless n is enabled on it. For some reason either the driver or systemd-rfkill.service blocks it every few minutes. Most other routers I connect to are okay.

here's some notes, if you want to try some tweaks, good luck:
