If your phone(s) is(are) connecting fine without bandwidth issues, it could be a malware infection that's causing problems on your desktop/laptop that's screwing with the OS's TCP stack.
In what way? Also, what channel your 5ghz is using does not really matter to much anymore, given that most if not all internet provider routers come configured using 80 Mhz channels, which is half of the wireless spectrum on 5 GHz.
I’ve learned that it doesn’t like to switch to the best channel all the time. I’ve used the channel monitoring software to confirm it was most likely that and not attenuation issues. Once I switched to a different channel that was not the same as my neighbors everything was fine.
I could be way off on this but that’s my personal experience
For 2.4 or 5 GHz?
5GHz
So basically a while back I noticed that 5GHz was starting to perform horribly in my bedroom, whereas in times before the speeds would dip a little because of the walls and doors, but still be faster than the 2.4. I didn't switch the location of any of my other network equipment.
So I started doing some investigating and after switching the channel everything worked like before. I live in a condo so I downloaded the software to see what people above and beside me were using, and if that caused any interference.
I chalked it up to that, but if you have any other ideas as to what it could be, I'm all ears breh. You seem to know your stuff
