Hello all, I'm a long-time Limewire user. I've been using it for several years now, but just recently, since my old computer crashed and I got a new one, I've been having a bad connection issue. I can turn the connection on, and then it may work for a little while, but it's very unstable. Searches can vary, from full results that I would regularly expect, to absolutely no results at all. I don't know why the connection keeps just diving.... Once I've started a download, the download works fine, but I just can't do any searches. I was wondering if anyone could help me with this.

Specs:
Windows XP Media Center Edition
2048MB RAM
NVIDIA GeForce 7300 LE+
AMD Athlon 64 X2 Dual Core Processor 4400+

Connection is;

Motorola SB5100 SURFboard Cable Modem


I don't know if any of that helps, but it's there just in case.... Also, I've noticed that my Default Gateway in my networking list often disappears, and I have to do a network repair to fix it.... Don't know what's up with this....
