Loss of internet with Alienware M15x

Hey, i have DSL internet with a modem plugged into the phone jack and then from that i have a Linksys WRT110 wireless router chained into the modem. from the wireless router i have a network cable running to my desktop, and my Xbox360.
Now here is the problem i have at most 4 wireless devices on my wireless netowork, and for some reason every time i open my M15x it screws up all the connections, meaning no internet love to any of the computers. when i dont have my m15x open everything is fine. Im not sure if this matter but 2 of the 4 computers are macbooks ? has anyone else had this problem before ?

 

Ip conflict maybe try to ser the m15x up with static ip outside the dhcp range,
but on the same subnet as the router.

 

i never thought of that, what should i change it to ?

 

Check the driver for the 5300, and the drivers for your wireless router. The 5300 should be a 7/30/10 driver and for your wireless router just search it up on the manufacturers website.

 

i made a static IP and it works fine now

 

this is happening again, need some help !

 

I feel like a noob for asking but how do i put my IP on a different DHCP ?

 

The problem with your question is that it doesn't make any sense to me.
what do you mean by different DHCP. There's only one DHCP server running on a router, so what do you actually want to achieve?

 

I cant connect to the internet with my m15x but i can with my other notebook. and iwas told if i put my computers IP on a different DHCP ? it doesnt make sense to me either

 

I NEEED HELP haha, i cant get on the internet at my house, but anywhere else i can perfectly, both on home networks and public networks, only at my house and only with my Alienware. My Macbook can connect perfectly unless my M15x is on searching for a connection?

 

What Wi-Fi card does the Alienware have on board?

 

Intel WiFi Link 5300, it connects everywhere fine besides by house.

 

if it connects everywhere it's your routeur failing ethier cheq for a firmware update for the routeur or change it

 

I udated the Firmware and still nothing, My router isnt that old, and it works with all other computers.

 

How is the network configured 802.11g or 802.11n, maybe mixed?
Are the other computers on it b/g or n?

 

Its on 802.11n

The other stuff I have not a clue what that means haha ?

 

Can someone please help me out on this ?
