I just purchased the PPC4100 and read that it would work with an SIDO WiFi card. So I ordered one up from Ebay. It's a SPECTEC WLAN 802.11b/g I figured it would be better than just a b card. But when I install the software, WLAN, it doesn't open. And when I check out connections I don't see an icon for network card. Can sombody please help me? I am not sure if it's the fact that it's a b/g card that is making it not work. Or some settings on the phone. Thank you

I have the same PPC and Spectec card. I've been sent an updated driver install and told to try soft and hard resets with the driver install. Neither has worked and I have yet to see the blue led come on or flash. Have you had any success?

Can anyone recommend a specific SDIO wifi card that works with the PPC4100? The SpecTec seems like a dead end.

Use Safecom SDIOI 802.11b Wireless LAN Card
model SDW11B

for a while now. I downloaded the latest drivers from Spectec. Connects just fine really.
