Hello,

I've been having an issue with my wifi extender where it regularly disconnects from the wifi after only an hour of use. If I reset it by unplugging it and plugging it back in, it works again, but only for an hour. Obviously doing this every hour would be very annoying. To resolve this, I looked into upgrading the firmware for my TL-WA855RE(US) V4.8

I downloaded what seemed to be the correct firmware, but ran into a brick wall logging into the extender's web portal (at tplinkrepeater.net). My router's password is more than 15 characters long and cannot be changed, so I am unable to login via tplinkrepeater.net and install the firmware. Is there any way to fix this or am I screwed?
