I am unable to upgrade the firmware from the 3.0.179 that came installed when I bought the router. I tried installing 3.0.205, 3.0.394 & the latest firmware 3.2.453, all fail at the end of the upload process. Inspecting requests on the browser window reveals that the router seems to be rejecting the upgrade with a 400 Bad Request with what appears to be missing auth_token cookie being sent with the request. What am I supposed to be doing here to fix the issue with upgrading my router?
