    6250 blocking UDP on new Win8.1 install

    GrahamSt

      Hi,

       

      Have a DELL laptop - and fitted this card a year or two back - worked perfectly with Win 7 Pro.

       

      Just rebuilt laptop to use Win 8.1, and now the wifi seems to be blocking some incoming UDP traffic.

       

      Turned off firewall to test = no difference.

       

      ALL latest drivers installed in the last 2 days.

       

      Turn OFF wifi and plug in an ethernet cable and my UDP packets get through - so its not my firewall etc.

       

      Run the same app on a Win7 laptop (on 2G) - and the packets get through so it not my router (unless its no longer getting through on 5G) - but I see no reason why this would have changed....

       

      The biggest change is to install windows 8.1 on this laptop :-O.

       

      Hope someone can advise what setting may be wrong under this new setup please ???.

       

      NB The traffic is from a completely separate box - on the same subnet (192.168.1.xxx), broadcasting to 255.255.255.255 port 56001.

       

      With the ethernet cable plugged in - I can see incoming packet in my app AND in NetMon 3.4 (microsoft). With the wifi connected - neither sees them :-O.

       

      Also they are short packets - a single line of text each (mainly 20-30 charcters or so).

       

      Thanks
