Extremely slow internet on one computer?

-Hi there i have a wireless router b970b huawei.. when i try to connect my laptop (hp pavilion dv67 VISTA) to the router, every computer dc and the laptop wont connect to the internet... however when i dc my laptop from the router, the rest of the computers go back online..You might want to check the network settings regarding the dhcp. It might be set to only give out one ip add.
maybe you left windows open the last time you used it
