I am running 2 Roku Ultras. They seemed good until 18 but when I tried to go back to 16, I got the same problems to a lessor degree. I think 18 have triggered something but the bad weather hit here about the same time as the up grade. New router, new HDD & looking at my antenna.
I am going to play with !he antenna and wait for the thunder storms. I may have to replace it also. Why do the problems seem to be worse at night?
I wish I knew more about routers. I think there are some opportunities there.
