"it's obvious the problem is not the router"
If a router reboots in use that means the router has issues. Routers do not reboot unless they have a bug.
Awhile back I bought a new computer for playing games online. (upgraded version of this : http://www.komplett.no/k/ci.aspx?sku=10274 )
I bought it without a a windows installation because i already had a copy of vista 64 cd which I installed when I got the computer. Then I realized vista couldnt handle the amount of ram my computer had or support some of the other new hardware, so i went online and purchased a copy on Windows 7 for 600dollars and digitally downloaded it from a non microsoft site, as it turned out after I installed it the cd validation key was not included in the purchase sadly so I was running it as trial version for 30 days.
Anyhow, at some point (and it has been going on for awhile) my router reboots quite frequently when I am online playing games such as Civilization 5 , world of warcraft and CoD on this computer. Sometimes it can reboot up to 3-4 times an hour if I'm really unlucky! When I'm not playing games and just surfing the web it is rare the router restarts, and while I sleep I keep my computer online and it dont reboot at all.
So it is basically when I play online games this occurs the most. However! If I play games online on my laptop or playstation 3 the router -never- reboots, so it's obvious the problem is not the router itself since it works with my ps3 and laptop but not my stationary gaming computer.
I have not a clue what is wrong please help me..
here is a log from my router right after it restarts : http://i54.tinypic.com/dfhkj8.png
It is a SpeedTouch 780 (0736JTG9C) wireless router, but I use a cable and turned on the WLAN setting.
