If I connect the network goes down?

[imported_dragracekid]

Ok heres the situation, i've been working fine on backtrack with my router at home and my parents shops router but in the last couple days if i try to connect the entire network goes down. When this happens the only thing i can do is shut my internet off, that seems to work, but im never able to get online. My partition of windows xp works fine with connecting so I don't know what to do. Any help would be greatly appreciated.

have you been "playing well" with ARP poisoning, and for some reason left the forwarding on?

I played around with it a little on one of them, I dont know if I did the other but I very well could have, how would I check if it is still on?

It may help to add that i have a third router that if i have that router plugged into a router im having problems with it works fine if that makes sense.

As arp doesn't go through a router (not counting devices that act as arp bridges)... it sounds a possible culprit

Thank you for the reply but i fixed one by restoring to factory defaults but now when I connect to the other its very hit and miss and drops internet without droping connection any ideas?

Nevermind I got it working both were verizon with the same setup so something went wrong, not sure what did but I did a hard reset on both and there fine now thank you all who replied.
