Go to LW's menu bar, Tools>Options>Advanced>Firewall. Change listening port to 64049. Restart LW.
If still no good, go back to advanced>firewall & turn UPnP off temporarily. Then change connection port to 64049. Trun UPnP on again. Restart LW. See if it makes any difference.
Are you running this LW whilst you have the other LW's running on the other computers? If yes, then try turning those ones off temporarily to see if that's the issue (the other ones are stealing all the bandwidth.) |
