WiFi in laptop is buggy

Question

WiFi

Good afternoon, habrachans,
I have a brand X laptop (I'll clarify later) that works strangely with WiFi.
It connects, but after a while it loses the network - pings to the router do not go through.
At the same time, the network indicator shows either that everything is OK, or there is no access to the Internet.

The rest of the devices on this router work fine.
What could it be? Is the driver or hardware broken?

Answer 1

Just yesterday I solved a similar problem by switching the router to 802.11 / n (before that, the car was between n and g). But I lost my connection due to the fact that there are many different 802.11 / g wi-fi points in the area.

Answer 2

I had a similar thing, and under Windows it is buggy, but under Ubuntu it works stably, so I sinned on the driver.

Answer 3

Driver.
Most likely the WiFi chipset is Atheros. They were buggy at one time, go to
www.atheros.cz/
and look for a new version

Answer 4

Thanks, I'll try to switch the drivers and the router.
