@Solla-topee Thanks very much.. that was the issue. I was on Lenovo P50 with Intel Wireless. I originally didn't that solved it but it was due to me not rememembering that i had changed the password...

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...
