For the 3rd issue, you may check the wireless channel of your CPE510, could that be DFS channels?

Brief introduction of DFS function

  @Somnus yes are DFS channels. but even disabling dfs the problem recurs

  @italy-user  Have you tried manually setting the channel on the CPE510? Not sure what channels are used in your area but if available try to set it to 161.

I actually would address the other issue first, even if it means exchanging the unit for another one.

hello everyone i got a new cpe510 unit to solve the problem, today while i was doing the first configuration out of haste instead of choosing italy as state i chose argentina... i tried to do a reset from web interface and later from POE but i don't see the TAB anymore to be able to select italy.
do you have any tips on how to fix it?
THANKS

Hi there! It sounds like you accidentally chose Argentina instead of Italy during the initial configuration of your CPE510 unit, and now you're unable to reset it to Italy. I'm not exactly sure how to fix this issue, but have you tried reaching out to the manufacturer's customer support? They may have some helpful tips or advice on how to reset your unit and Choosing Italy as your state. Best of luck!
