Hi, I'm having problems connecting to the network.

Limewire opens fine, the connection bars are perfectly healthy.
When I run a search, Nothing is found, I notice that in and out traffic remains at 0kb.
Shorlty after this I get a message saying that my ppp network is disconnectd.
Usually I have to reregister my wireless modem to the mynow network just to make my internet work.
Anyone have any ideas what the problem could be?

Thanks.
