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).
When I re-enabled wifi, the packets started arriving again....
Until Windows screensaver kicked in, then they were lost again - until I stopped and restarted Wifi :-O, when once again they started to arrive.
Looks like its related to screensaver then :-O - but I cannot see any screen saver/power management settings which could cause this :-O.
NB The laptop is NOT going to sleep - just turning off the display. No specific screen saver selected - just the default then I guess.
Hi Graham, I would recommend checking with the http://www.intel.com/support/oems.htm system manufacturer if this wireless adapter model was validated for your computer because the fact that this is a WiFi + WiMAX adapter could introduce some undesired effects.

Thanks for at least responding - but this 'answer' is worse than useless. It sends me on a paper chase through the DELL site where I cannot find if this card is 'warranted' to work or not :-((.
Basically - I bought a laptop - actually from Dell but that is irrelevant.I then bought a perfectly good WIFI adapter, and installed it into the Dell - as the fitted adapter did not support 5G. Its been working for many years now - quite happily. Its designed to a BUS STANDARD - so should be installable in any PC matching that standard.
I really don't see the point of your email - it does nothing at all to answer the question - just 'slippy-shoulders' the issue :-((.
Not impressed in the least with this response :-((.
Maybe I should STOP using equipment based on Intel products if you cannot (or will not) support them then.....
It was a simple enough question in the first place - and I did NOT need to be lectured about regulatory compliance etc.
