at the moment I am trying to activate USB-Tethering on a Linksys MR8300. There is an articel here how to aktivate it, but I have no WAN connection. WAN connection should be established over USB Tethering. I read about a possibility to download the needed files on a PC and upload it wire web interface to the router. Did I understand the possibility that there is also a way? How I can do that? Is there anybody who could help me? A short instruction how I can do that will be very appreciated!
yet another option is to share internet from your phone, connect to the phones wifi hotspot with your router, by doing a network->scan->join (put the connection in the wan zone), and install the packages that way.
