Thank you for your reply.
The reason I know it's somebody's phone is because I used to have the
same problem with my 2.4G phone until I bought a new 5G phone. Most
times when I used the phone (not always) I killed the connection,
interrupted downloads, etc. However, it could be anything - it doesn't
really matter
I am not sure you are correct on item 1. The same problem occurred
when I used all wired connections and used my old 2.4G phone. I would
get a pop-up on my connection icon saying something about cable being
unplugged or something to that nature. It would restore the connection
but may drop it again. This would happen until I hang up, then
everything is fine.
On item 2: yes, I know it's possible to change channels. The question
really was: was there a way to eliminate problems, not change the
channels. Sorry if I didn't make myself clearer
Thanks again.
