I think your internet drop out has nothing to do with limewire, but when you keep seeing need more sources it more than likely means that they are fake files...
Fake files showing up in search results
I also noticed you said you see a wall in front of the globe, this can also cause some problems with connecting, speeds and downloading....
Make sure you have the zonealarm firewall properly configured to allow limewire...
Also your router has a built in Nat firewall and you should Port Forward to open up a port for limewire...
These are your instructions for your Netgear DG834G....
