[out of the blue]

hello, i just joined up after buying SH 4 and i ran into a couple problems even after getting the 1.4 update. i was having a problem where i would start up a room on ubi, and my friend said my latency was at 999, then after looking around for solutions i called my internet provider and they walked me through some stuff with my new router (never had a problem with online gaming before i got this router, i am directly hooked up to it with a laptop as satallite.) now i can start and join games just fine, and my friends can join my rooms, but after about 5-15 seconds my internet crashes and the game discontinues. then after i close out of the game, my internet reestablishes connection. i am out of ideas, and was hoping someone here ran into the same problem, and found a fix. thanks either way.
