Linksys RV082 Router Reset....

Hi all,

I have a Linksys RV082 router and i connect to an external network
using this router and i use multiple PPTP clients to connect to the
same external server ( the PPTP clients are from different OS ). But,
my problem is the Linksys is getting reset very often say every 1 hr
but even after i restore the Linksys connection, my pptp clients
couldn't connect to the server . Any idea why this is happen ?. Any
known problems on the Linksys RV082 router resets ?.
Can someone pls shed some light on this.

Thanks and Regards
