I have been having a reoccurring issue with my router authentication. Username and password has no changed, maybe once every couple of weeks my internet drops out. The issue is always the password it is still correct but it no longer authenticates. Now I use an ASUS AC86U but the problem is router independent it still happens on the plusnet router. All lights on the ONT are fine.
I change my password, enter the new one and it’s okay working again. Any idea how I stop this happening?
