Connection distruption WiFi/WLAN

[trintin7]

Router Linksys Ciso E1000 V2.1
I have the network which is consist of PCs and Laptops. PC is connected via LAN and for laptops is connected using Wireless B or N. Whenever PC plays online game (ie. TF2, Garry's Mod (basically Source game)) all of the laptop that is connected via WLAN will go down no wireless connection can't be made at all but the PCs that are connected via LAN is still working fine.

Is there anyway to fix this ?

it might be that the gaming is taking all the bandwidth.

look into QoS settings. set gaming to low.

Wow...that much bandwidth? I'd have called my ISP and given them an earful...

QoS is disabled and I turned it on and add the game. Still having the same problem
