If you used to D/L at a speed more than 10k/b and suddenly it dropped to 0k/b here is what i did and poof my D/L speed is back!

Open Limewire. do not connect to limewire first.

Go Tools,Options Bug Reports:Check if, Received incoming this session: true or false? if true no problem, if false you may have a firewall blocking.

Next Tools,Option, Advanced, Firewall Config: Put 80 in the listen on port instead of 6346. Next Use Manual Port Fowarding and enter 80.

Next Hit Connect!

DONE!
