Hallo ,
               one of  my wrt54gs v2.0  seems to have a problem,

   Stops responding to any network traffic  and freezes. No ping reply nothing .This is happen once-twice a day. The solution is to  make  2-3 (never one) power-on-off  and then the router is ok. This problem  it doesnt happen under heavy traffic. 
Now runing RC4  but the problem appear 1 month ago... when running Talisman over 3 months.

Can I run this script on my wrt54gsv2.0  http://forum.openwrt.org/viewtopic.php?id=2874

Any other ideas of what is wrong?

Thanks in advance
