I have the Buffalo WHR-G54S router and since i got it i have problems with it.
I connected an external 16dbi antenna on it. Everything works fine except that msn live messenger and windows messenger cant sign in. First i enabled the upnp support on the routers settings but still having the same problem
I even cant open some web pages like MSN.com
or mobile.de - der Automarkt für Gebrauchtwagen und Neufahrzeuge - Finden oder Verkaufen Sie einfach und schnell ihr Auto
... it sounds very strange but its true
My ISP said that everything shoud be working and that all ports are open. And since i live in croatia i cant count on my ISP provider and the service.
I really dont get it because it seems that everything i change in the routers settings doesnt have any affect on the problem. I really dont want to flash the firmware on the router because i never did something like that before.
Sometimes i would like to make a warcraft3 server, and even i know the port the game is using, it seems that i cant disable the firewall of the router.
I tryed everything i know (change settings, apply, reset of router, plug in/out, and even reinstalled windows) but since i dont know much about router/ap-s i hope that someone can help.
Any suggestions would be nice. Thanks to all who are willing to help and sorry for my bad english
