Gnutella Forums - No Luck With Tiscali!

HI ALL!
I HAVE BEEN USING LIMEWIRE FOR ABOUT A YEAR NOW AND I'M HAVING VERY STRANGE CONNECTION PROBLEMS. ONE DAY IT MIGHT CONNECT BRILLIANTLY N THE NEXT FEW IT WONT!
FOR INSTANCE TODAY I WILL BE ABLE TO DOWNLOAD ALL DAY AND ALL OF A SUDDEN A FIREWALL WILL APPEAR IN FRONT OF THE BLUE GLOBE EVENTHOUGH I HAVE TURNED THE WINDOWS FIREWALL OFF!
1. OS VERSION IS WINDOWS XP
2. THE ONLY ANTI VIRUS STUFF I CAN FIND IN MY COMPUTER IS WINDOWS FIREWALL AND THE AVG FREE EDITION
3. I HAVE 448mb OF RAM
4. NOT SURE HOW MUCH HARD DISC SPACE IS AVAILABLE
5. CONNECTION TYPE IS BROADBAND
6. MODEM IS SAGEM F@ST 800 E3
7. TRYING TO CONNECT FROM HOME
8. USING VERSION LIMEWIRE PRO
9. MY ISP PROVIDER IS TISCALI
10. I DID THE TEST AND IT STATED ' YOUR TEST WORKED'
11. NOT SHARING COMP OR P2P PROGRAMMES
12. LW HAS WORKED PERFECTLY IN THE PAST WITH COMP I'M USING NOW.

CAN ANYONE HELP ME PLEASE. FIREGEM
