Have you tried resetting the router manually?
If you dont know how to manually reset, heres how:
Locate the reset button(Its a small hole) of the router.
Using a pointed object, press and hold the reset button for atleast 8 seconds(You will see all the lights blink and light up again.)
Now try reconfiguring the router. After that hit 'Save and Reboot' in the router 'System' page.
Its better if you've saved the configuration file(config.bin). Its easier to upload it rather than wasting time configuring.
Restart your PC and try connecting.
Hope this helps.
