Here is a strange one: I click on "Open Download Manager" from the BitTorrent section in the config pages and I get: "Internet Explorer cannot display the webpage". Anybody run into this before? Note that I also tried to get there from a mac and no joy.
If you do the factory reset do it from the web interface under maintenance.
Also before that happens I would force flash the firmware.
Step by step directions can be found by searching the forums by force firmware.
