Wifi slow and droping: Intel Wireless 7260

Post by nicochengdu » Mon Feb 26, 2018 5:36 am

Hi!
I have a very slow and droping Wifi with a signal strengh usually between 50-60% even if i'm very close from the Wifi box.
I've read a lot but understood little... so I finally decided to post on the forum,

I first five you the info on my system and then tell you what I've already tried.
I'm not familiar with command but I saw on other posts about slow Wifi that they often ask fot those command results, so I put them here.
Hope you can find something interesting in some of those data.

What I've tried:
1. to turn off the Disable power management for the wireless card
2. Disable IPv6
3. temporarily disable Bluetooth
4. I've search for Realtek Semiconductor Corp. RTS5129 Card Reader Controller (even if it's seems to be more about USB connection than Wifi) and Intel Corporation Wireless 7260 driver but can't find them on their respective official sites nor of forums. They seems to be outdated. (bought my computer in january 2015).

In some post they say it might because of a kernel update. I don't know how to check that. In other postss, they propose to install some linux headers, seems a bit complicated and I don't want to start to manipulate important files without supervision.

Thanks for your help!
Nicolas

Reason: [c] is good for 1 code line, but crap for blocks of screen output. - Replaced all the [c] [/c] tags by [code] [/code] tags. - [code] [/code] is the better choice for blocks of screen output
