Network auto disconnect

[Craziest]

I'm using window 7 ultimate , my pc connected to a TP-Link 54M TL-WR340G (wifi router) connected to a netgear (that i don't remember the name)
The issue is my network run pretty fine with 3pc connected into the wifi router
But the problem is everytime I run window media player (11) on my pc , the router ultimately reboot exactly at the moment wmp appear
Can anyone help me solve this problem cause it really annoying
(Sr for the bad english)

Well I would download the firmware update then update it to make sure.

Make sure you get the right one. Since theres 4 versions. It'll say what yours is on the bottom

But use an ethernet cable not wireless to update it
