Internet only sporadically works while DayZing

[GotAWarInTheHead 16]

When ever I am playing DayZ, it seems my internet only works once in a while.  If I ALT+TAB out of DayZ and go on to a website -- say the DayZ map -- it most likely won't work.  Then, I go back to playing for five minutes, and back out again, the map suddenly works.  I don't care about this happening on my computer -- I'll just open the map and stuff before hand -- but I do not want this to happen to other computers on my wireless network (live at parents).

 

Is there any fix for this -- or is there anyway to limit the bandwidth going to just my computer so I keep some on the side for my parents' computers?

 

THANKZ DAYZERZ.

its just that dayz takes up your internet but it wont affect others in the house, that's why it takes FOREVER To load.

It does, though.  If I'm playing DayZ, the internet on my (other computer) laptop won't work most of the time. :(
