I'll point you in the direction of another temp fix... As wireless B/G modes only support 50mbps (52 or something) that's the TOTAL for the network.... So how many people are using wireless on your router? Also if anyone is on a LAN connection and you use heavy wireless they sometimes can have 2 options. 1-LAN takes priority or 2-WAN locks up lan due to encryption because of the router. All this does what you say? Gives you ****ty ping. So my reccomendation? try a land line.... If that doesn't work try flashing the router with DD-WRT firmware. If that doesn't help, get a new router. When Cisco bought Linksys they ****ed up the routers bad, making them crappy pieces of ****, 2MB flash and 4MB ram, ****TY!!!
