LAN disconnection issue

Dear all,

 

I have a single PC on a LAN that every few days suddenly reports a "Red X" and no connection to the LAN.

 

I've run a cable test, and no error/short etc. is reported.

 

I restart the switch, and all is working again.

 

Has anybody experienced anything like this? Do I have a defective switch, perhaps it's best to warranty swap out?

 

Any advice welcome. BTW: I do not have a support contract, so cannot ask Netgear which I find a real irritation! (Note for Netgear)

 

Best regards,

D.

    Hi Donchik,

     

    As far as I know, there is no compatibility issue between the GS724Tv3 switch and Realtek GBe PCIe LAN card.  A new firmware version  for the GS724Tv3 switch has been released which is the v5.4.2.25.  I suggest you to try to upload it to your GS724Tv3 switch.  You may download it here.  Be reminded to perform a factory reset after updating the firmware then reconfigure it from scratch.  Observe if same problem will occur.

     

     

    Regards,

    a. Have you tried connecting another PC or laptop to your GS724Tv3 switch?? 

    b. Does same problem occur if you connect your PC to other LAN ports of your GS724Tv3 switch?

    c. Have you tried to update the software driver of the LAN adapter of your PC?

    d. What is the current firmware version of your GS724Tv3 switch?

    e. Have you tried to perform a factory reset on your GS724Tv3 switch?

      Hi DaneA,

       

      a. I've hooked up other devices, but as they need to sit at the location for several days before the issue appears, I've not been able to isolate it.

      b. Other PC's on the network do not appear to have this or similar issue.

      c. Yes Latest LAN drivers installed.

      d. I think this is the latest

      Model NameBoot VersionSoftware Version
      GS724Tv3B5.1.1.15.4.2.19

      e. Yes as part of the latest firmware update.

       

      Thanks for the assistance,

      D.

        Hi Donchik,

         

        You may try to open command prompt on the PC where the problem appears that is connected to the GS724Tv3 then do a continuous ping to the IP address of another PC that is also connected to the GS724Tv3 and vice versa.  Observe which PC will time out first and which PC will still continuously ping.

         

         

        Regards,
