Ubuntu – Dell Inspiron Intel 7260 Wifi connects and then drops on Ubuntu 14.04


I've been trying to connect my wireless card unsuccessfully. I've tried similar questions/answers with no luck. I tried with Ubuntu 13.10 with same results but loading latest iwlwifi-7260-7.ucode did work for a while, till now with 14.04.

The laptop's wifi card is "Intel Corporation Wireless 7260".

dmesg | grep iwlwifi

Tried using iwlwifi-7260-7.ucode and iwlwifi-7260-8.ucode but same results.

I'm newbee in linux, so in my case a solution is like a "terrible crutch", but it works for me now. I use the same linux - Kubuntu 14.04 and chip Intel-7260 rev.73.

I found out, that system on my notebook uses wlwifi-7260-7.ucode. Also, I have tried to make something from backports. No, realy, I don't know, what exactly I have made %(

Eventually I just substituted the file! Instead "wlwifi-7260-7.ucode" I copied with same name file wlwifi-7260-8.ucode and voila- it's works fairly well:)

Yeah, I know, that is stupid. I just haven't any more time to digging.
