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
Graham
