Not sure if that is Manjaro related, still want to ask you.
I have an issue with my WIFI - it is terribly inconsistent. I can se WiFI networks, can connect to them, but it is very difficult to do anything as the connection comes and goes every few seconds/minutes. Sometimes there days it is very good, sometimes it is very bad (like today). I think this can be related to ISP router (Virgin Hub if that matters), reboot helps just for a time being. How can I check that at my end in order to report problem to ISP provider (if that’s the case)?
I think I’ve found the reason of the problem. I have no evidence, it is just my guess and so far it works.
I think the problem is this cheap wifi adapter I’ve bought for £1 on aliexpress:
It gets very hot when plugged into USB 3.0 (which was the case), at the same time disrupting work of main wifi adapter (I have few connected). It is bit better when plugged into USB 2.0, still it becomes very hot as well.
I’ve removed the adapter and things have significantly improved.
