Intel 7260 dual band problems

sweisman · 2016-05-01 07:57:36

I have a Sony Vaio T. I recently upgraded my Wi-Fi card to a dual band + Bluetooth Intel 7260 controller.

I have been experiencing all sorts of weirdness using kernels after 4.3.3-3, so I keep it at that version. Upon upgrading, the new card is recognized, but no networks show up. I am using ConnMan and have had no problems until now.

I did some experimenting by installing the newest 4.5 kernel, and then the card just disappeared altogether. So back to 4.3.3-3.

I found a post with a hard to see comment to the effect that if you downgrade wpa_supplicant to 2.3 (which I thankfully had in my cache), the card will work. I tried this, and indeed it did work. Just in case others are experiencing problems, these tips might help.

I sure wish it worked with the current kernel and wpa_supplicant. Any idea why it doesn't? Is some sort of configuration magic needed?

I know nothing of this hardware, is it supported natively in the kernel or did you need to compile a module for the 4.3.3 kernel?

I use stock packages. It is completely supported.

However, kernels later than 4.3 have issues with display (and now, I discovered, my new Wi-Fi card). The HDMI out doesn't seem to work at all, for example (I have no problem running dual monitor with HDMI and VGA both at full HD resolution). I figure there's some config tweaking I can do, but I don't know. I've asked for help before on this, but got no useful replies.

Maybe post some relevant hardware info from `lspci -vvv`

Did it disappear from lspci results in kernel 4.5?
