"windows tell this wireless card is not compatibility with win 8.1 yet !! "

Well then why did you upgrade to 8? At a loss?

Your Solution = Go back to windows 7, where your card is supported. Get another card that is supported under windows 8(8.1)

That is a REALLY OLD card anyway.. How about something like this

Hello,

Like Budman said, not only is that card not compatible with Windows 8.1, but 3Com doesnt exist anymore so I doubt you will get a driver update that works.

Im actually having a hard time finding any decent PCI wireless card. USB a option?

Its a Desktop - why is Wire not an option? ;) Both of the cards I linked to got decent reviews.. I would think either of those should work riahc3?

Before going through the trouble of downgrading, is there  a way to get the Win7 driver working on Win8?

Good chance that the Windows 7 driver just work on Windows 8.1, I've got here a Windows Vista, 7 and 8 machine, and all they are now all running Windows 8.1 with their original drivers and work great!

Its a POS card from like 2005, even if the windows 7 driver works.. It is G only, OP - is your wireless network only G? If so then sure you could try that, curious why the upgrade process just didn't keep the driver that was working then?

Yikes, G only? :s If it's a desktop, time to find a new card!

The whole desktop is prob due for replacement, Think 755 was circa 2008 if not mistaken.. Even with some updates its got to be horrific on 8 I would think..

Maybe he got one of the last ones off the line or something with a bit more umph? Maybe its just me, 3 years is about the life of a PC at most, even with upgrades along way. I bought myself some time on my old dell XPS 8300 (2011) with SSD, bumped to 12GB and newer graphics, usb 3 card. Not all at once, memory was first, then say 6+ months ago graphics HD 7700 with 2GB, on the cheap $100 and most recent the SSD, prices have dropped and the 840 Pro's were just getting all kinds of great write ups.. The SSD was the biggest improvement - should get me through 2014 I would think. Just couple weeks ago got a usb 3 card for it.. It was like watching paint dry moving anything via usb..

5 year old box I am guessing - its about time for update I think! Did you ask Santa? ;)

Hello,

TP-LINK TL-WN951N Wireless N300 Advanced PCI Adapter, 300Mbps, w/WPS Button, IEEE 802.1b/g/n, WEP/WPA/WPA2

TP-LINK TL-WN951N V3 has drivers released on 6/20/2013 compatible with Windows 8 (note, not Windows 8.1, there have been a couple of hardware that are compatible with 8 but not 8.1. You should be OK though)

TP-LINK TL-WN751ND Wireless N150 PCI Adapter, 150Mbps, IEEE 802.11b/g/n, WEP, WPA/WPA2

On the TP-LINK site, there are no drivers for this card for Windows 8/8.1 Last driver download was released on 11/22/2012

Id go for a USB 802.11n adapter IMO...
