I purchased an Obi200 last week and it worked fine with the provided ethernet cable. I then purchased an ObiWiFi wireless adapter. I had difficulty with the provided instructions. For example the ObiWiFi_Setup network was not appearing until a long delay. I'm not sure what I did, but when I connected my PC to that network, now I can no longer connect my PC wirelessly to my modem. I can only connect to my modem now with an ethernet cable. I've tried every option I can think of: rebooting the PC, unplugging and plugging back in the modem, deleting the wireless network from my PC, and so on. The network appears as "Unidentified Network (5-digit network name)", and indicates "Access: Limited Connectivity". When I go to Network and Sharing Center, it appears listed as "Unidentified Network (Public Network)". My OS is Windows Vista.
Appreciate any advice.
