I have a Huawei R201 MiFi connected to the internet, and I'd like to use its internet connection even from devices that don't have WiFi, so I grabbed a wireless router I had lying around and configured WDS so that it'd connect to the MiFi, and this is working nicely (I can ping the MiFi from the router web interface).
The next step was connecting my PC to the router via ethernet cable, but now I'm stuck... The PC can ping the router, but not the MiFi (they're all on the same subnet). Since the router can ping the MiFi, I guess this is some kind of routing issue? Should I get a more "flexible" router, such as one with DD-WRT maybe? Is what I'm trying to do even possible?
(For the record the PC is running Lubuntu 11.10)
