I think I sort of agree. I have read that this hub wireless system tends to overload very easily and for me if I connect 2 smartphones that's it. I'm going to try installing this Insidder app and change the wireless channel again, I will keep an eye on it.
At the moment I would like to put this thread on hold for a few days so that I can observe what it does now.
Thank you all for the help given so far.
Yes I think that's right but it is weird how I changed the channels before and it resulted to be worse so I put it back to automatic and it was better than nothing, now I put it to ch 11 and seems to work, I still want to try that insider app once I get 5 mins free in life..:)
