Qeroca (DayZ)

need more info than just that.

I just build a new PC which includes I5 3570K Radeon 7850 8GIGs ram Asrock Z77pro4-m 775 watts Netis WF-2113 300mps wireless-N PCIe adapter 320 gig hardrive windows 7 comcast internet. When i load up into a server on DayZ, my latency spikes up while it says "waiting for Host" which then it lags my internet completely, i d/c from Ventrilo, Skype, What ever is up. the weird thing is, if i disconnect my internet and connect back up, it will load me into the server, but then if i go to hit OK. it will just do the same thing. My old PC i built was terrible at handling this game, but would not do this to me at all. Afterwards, my internet becomes extremely slow for a few minutes. Even if i play other games like League of Legends or The Stress test for GW2, i would have no problem getting into them, and run well. Does anyone have an ideas why this does it? or if there are any settings i can change to give more priority to DayZ for internet? any help would be great!
