Androids, ipads, Macbooks, Win 7 PC/laptops have not caused any such problems with this bridge/repeater. This router has been working flawlessly for months until this Win 8 laptop entered the mix.
The same offending Windows 8 laptop can connect to the Gateway Archer C7 (running 1.7.1) in AP+WDS mode with NO problems.

Help! Has anyone else experienced this? How do I get this repeater to play nice with this Win 8 laptop?
