Ubuntu cuts down wifi hotspot on lenovo laptop, what to do?

Question

linux

Installed Ubuntu 14/04 LTS. Notebook LENOVO Z710.
Installed without problems, but now when I log in. I connect to Wifi, to my access point (TP-Link TL-WR740N), every 5-10 minutes disconnect. It’s even hard to call it a disconnect, Wi-Fi falls off, phones, tablets don’t see it either, it only helps to reboot the access point, and everything is new .... In Windows, such problems have not been observed for half a year, half a year ago there was another laptop , on the same access point on the same distribution kit 14.04 everything was fine without any complaints... Help please.

The problem is not in the laptop.

Answer 2

What does the access point to the laptop have to do with it? With an access point, it turns out, problems.

Answer 3

Remove the variety package (a program for automatically changing wallpaper on the desktop) - problems with the router arise due to the inadequate behavior of this particular package. the package, even with the image download settings turned off, fumbles maniacally in the local network, which causes the WiFi router to crash.
