X3 modem browsing issue!!!!!!!!!

HELP !!!

my X3 modem has a browsing issue !!! I have to restart the modem every 5 min
when i ping the DNS or any web site  i got a reply with any Loss ,i have checked cpu load i found that i rise between 81% and 95 % (Is this normal?).

I have a Private IP of /24. (Could this causing this issue ?)
i checked nat stats i found a lots dropped sessions.
this is a serious issue cause i can' t use any wireless devices or more than 2 PCs, I han 2mbps/512kbps connection, i have tried everthing ,cleanning PCs tracking downloading PCs in vain, seems that a traffic is there but after a certain time there is no longer TCP traffic but VOIP still working without any problem,
could you please help me to handle this issue.

Ding,

I think Nimrod is right in diagnosing the session count issue.

In iMonitor for your site, select the "Probe" tab. At the right you will see the Protocal Processor, with a drop down box labeled Protocol Layer, select "Spoof" then click the "View Stats" button. Near the top of the list of results you should see a entry called "SessionCount"
The number there should equal around 10 or 20 for each PC you have on the LAN behind the modem and 4 to 6 for each VoIP. So if you have 5 PC's expect between 50 and 100 Sessions. If its way more than what the math should total, its not a VSAT problem but a LAN issue. I would go to each PC and from the command line enter the NETSTAT command (this will tell you exactly how many sessions each PC has open. )

What your looking for is the infected machine with LOTS of open sessions, which would be likely caused by a DOS (denial of service) virus, which opens so many ports that the network becomes unusable). Remove that PC from the LAN and see if the issue persists.

ok,

I think you should get better support from your provider, but here are some things you can try, as it looks like a maleware openning too many sessions indeed. So I suggest the following:
1. disconnect computer by computer and check if network becomes better; try to isolate the problematic computer or computers.
2. Try to offload from the X3 modem, for example, using external good router like Cisco for the NAT.

Good luck and tell us how it goes
Nimrod
