I am installing a pair of CPE510 access points as a bridge between two buildings approximately 300m apart.  I set them up per the instructions and the TP-Link video on Youtube; however, I did not set a password, nor set it to MAXtream, and would now like to.  I have mounted the access point and it appears to function. I saw in the instructions how I should have set a security password. I reconfigured and reconnected my laptop, as proscribed in the instruction manual, but I'm unable to get to the logon page of Pharos. Chrome says the site is unreachable.  I reset my laptop to 192.168.0.25. The Access Point is 192.168.0.254.

Do I need to reset the Access Point and start over? Thanks.
