I cannot say that I'll be able to help with this one, but I can tell you this much: I seriously doubt you'll get an answer of any substance without more detail. Mention things like:
1. WHAT ARE YOU TRYING TO DO? So, are you trying to connect over wifi, wlan, what?
2. If over WLAN, who is the provider?
3. What phones have you tried, what OS, what OS version, etc?
4. If you're trying to connect over wifi, then what is the router brand/model/firmware?
