Pretty simple (in theory) question.  I can't get any of my laptops to log on to the extender.  I have quadruple checked passwords and have tried on 2.4 and 5 and have updated firmware to latest version. Anybody else had this problem. Otherwise everything seems fine-linked to my main router, i can change passwords, log in to device via app, etc.

I haven't done reset yet though next on my list if i don't get any other advice here.

Thanks in advance for any help.
