Network problems, can't play gw anymore...

Hi, I've been playing guildwars for about 6 months now, and, now that I changed my connection to wireless, it is impossible for me to get the game to work properly. As soon as I decide to start the game, every other program that is connected to internet gets immediately logged out, and guildwars doesnt even start. I've tried configuring the router thousand times. Disabled firewalls. Configured router again and ensured the ports guildwars uses are open, and nothing. Still, as soon as I start guildwars my connection to internet gets screwed and I can no longer do anything on internet. Can anyone help me with this?

What kind of router and wireless adapter do you have?

Router: WHR-G54S Wireless-G High Speed Router & Access Point
Adapter: WLI2-PCI-G54S Wireless-G High Speed PCI Adapter

I just updated the firmware for the router, which shouldve fixed a disconnect issue, according to the buffalo webpage, thou it doesn't give a description. So far ive been connected on BOTH internet and guildwars for almost 15 minutes with no problems, I hope it goes on like this. Anyway i'd STILL like to know if anyone has had the same problems and ideas to solve them, for if they appeared again tomorrow... And also id like to let you know my oppinion on buffalo technologies now is the same that I have about microsoft ¬¬ Only billy or anyone like him wouldve shipped a wireless internet router that disconnects itself all the time ¬¬

Are you using any security protocols on the connection? I have a wirelesss set up at home as well. My router is a D-Link DGL-4300 with WPA enabled with MAC filtering active. I originally tried to run it with just MAC filtering and got frequent connection drops. Once I switched on WPA, the connection became 100% stable.

Whats MAC and WPA? Im new to wireless neway im not even running on a codified connection,theres no need for it here since wireless connections arent common...

The MAC address is a series of letters and numbers that are unique to every network card, whether land line or wireless (spoofing doesn't count!). MAC Address filtering means that only MAC Addresses on your router's safe-list are allowed to connect through your router. WPA is an encryption protocol that prevents other people from spying on your connection and capturing keystrokes or other confidential info. You definitely want to use some kind of wireless encryption if you want to avoid hackers listening to your online key strokes... they might capture passwords, CC#'s, etc...

Well I was trying to use AOSS yesterday but with connection being a crap it was useless to even try ¬¬ Ill try to set it again today thou, maybe ill have better luck now
