netgear gs308t dropping frames

bought a netgear gs308t mainly for igmp multicast as my amplifi hd router was flooding the other ports when watching iptv and plan to learn about the rest of the features later on so theve been left at default,this is my first managed switch so I'm a bit lost with all the settings,the problem is out the box without changing any setting 's in the port detailed statistics its showing alot of dropped transmit frames on the g1 port which connects to my bt hub,my nvidia shield is connected to port g2,after I enabled igmp the frame drops go through the roof,jst continually dropping frames,after about a hour of iptv port g1 to my bt hub is showing 15511 frame drops while my nvidia shield in port g2 is showing 111 frame drops,I presume this is bad?although I haven't noticed any problems yet,my download speed is the same,I enabled RSTP but it didnt make any difference,so I'm at a loss here

    Easy test is to put the bt hub on a different port. 

    If that port starts having dropped frames/packets, then I'd try replacing the connecting ethernet cord first.

        I own a GS308T and it works fine for me. However the traffic flowing through it is very light. I have another switch that was just flooded with transmit errors, but it was heavily used. There were several HD cameras connected to it plus a NVR and another switch with several HD cameras. I replaced it with a more powerful switch and assigned it to lighter duties. None of them shows any errors now.

    Hash70,

     

    NETGEAR recently released a new GS308T firmware which is v1.0.5.5.  I suggest you to update the firmware then observe if the same problem will occur.  

     

    You can download GS308T firmware v1.0.5.5 here

     

     

    Regards,

      The new firmware does not offer any performance improvements. You need a better switch, i.e. a switch with a faster processor and/or with more memory.
