Wireless on my laptop (Lenovo G70-80, Windows 10) randomly disconnects, and then few seconds later reconnects. I am not 100% sure but maybe it gets worse when I try to download large packages (200mb file or if I open YouTube video). Or maybe it's just more noticable then. But it's random, and it could happen a dozen times in two minutes, and not a single time in an hour.


1. I think this started when I received new router (ZTE ZXDSL 931VII).
However.. there is no problem when I use my (android) mobile phone. Wireless loss is only on the laptop.

2. I updated drivers. Didn't help. Didn't think it would anyway.
I set the channel to 9, which is not used by any nearby routers (and neither are adjacent 8 and 10 channels). No effect. Also tried switching from Mixed to whatever is the newest one. No change.

3. Signal of wireless is excellent (until disconnect happens, then it shows a drop for a while until it reconnets). Everything is fine. Physical wires between router and a phone line might be a bit problematic, but everything else works fine but laptop wireless.


I'm out of ideas so please help. It's really annoying especially since Chrome freezes every time disconnect happens.

Adapter is Qualcomm Atheros AR956x.


PS: I tried disabling "Allow computer to turn off this device to save power" but to no avail.


I think I'll ask ISP for a new router unless someone has an idea. I heard some routers of this model are faulty.

Update:
Fixed. Or so it seems.




I contacted my ISP. They reset router settings (which apparently are stored server-side, even though I thought I can change some myself). After that it seems my problem got fixed.

I asked for an example of settings that were fixed/reverted and I was told that the channel was set to "1" and now they reverted it back to "auto". Which is weird because on my end it looked as if auto was initial setting, which then I tried changing to 9 when attempting to fix the problem. But if I do that on my end it doesn't seem to matter, the router loads settings from their server (I thought this applied only to some settings like username/pass and DNS).
