SAR715PV CPU Utilization

Discussion in 'Broadband' started by Lynton Towler, Nov 20, 2003.

  1. Hi,
    I have recently purchased a Solwise SAR715PV ADSL Modem/Router and am
    having a problem with it.
    The router in question has a built in VPN server which may well be the cause
    of the problem so I'm interested if anyone has had any experience with this

    I first noticed there was a problem when using videophone software when
    periodically the streaming audio and video just grinds to a halt followed a
    few seconds later by lots of garbled audio and missed video frames.

    I downloaded a diagnostic software called Netspeedo which indicates the CPU
    utilization on the router is at 100% when the system stops working and goes
    back to 4%~ when things return to normal.

    I'm wondering if anyone else has had a problem like this with this
    particular router ?

    The Firmware the router is running is "pheenet_ddns_030627", although this
    is not quite the latest version I am led to believe that the latest version
    for some reason doesn't allow the router clock to synchronize to an NTP time
    source which I think is a necessity for a reliable VPN.

    There is no problem with the ADSL connection or line because I have my old
    trusty (VPNless) SAR715 which works absolutely fine with videophone etc etc.

    Your comments are welcome !

    Best advice is Upgrade it, as I have seen this as well and after upgrading
    all is ok. I dont use NTP on the router as my gateway does this for my

    Hi Bit of an update. Have you got dynDNS setup ? as this is the cause of the
    cycling I have had on a PV. Clear the entry and save twice. as saving once
    it kept cycling and its now solid after the second save.

  4. Hi,
    I do not run DynDNS here Ian so its looking like I'll have to perform a
    firmware upgrade at the weekend and hope that cures my problems.

    Thanks for the response - I'll let you know what
