said by AndrewShnide  :Can same WiFi network card receive wireless signal from router and send it out to another PC using wireless AD-HOC connection? You asked two questions: Subject line "Can Wi-Fi network card recieve and send at same time?" Answer NO. The radio operates in what is called half duplex mode and can only receive OR transmit.
Second question: Only if the card can be controled by suitable software to operate in "repeater" mode, but as stated by nwrickert, not many WiFi cards can. Many wireless routers are available, however, to do this either out of the box from the mfgr. or using third-party firmware on them.

I believe you can now with Windows 7 hidden feature. Not sure if this does exactly that though, but still interesting.

"It wasn't all that long ago that Microsoft was talking up the Virtual WiFi feature developed by Microsoft Research and set for inclusion in Windows 7, but something got lost along the road to release day, and the functionality never officially made it into the OS. As you might expect with anything as big and complicated as an operating system though, some of that code did make it into the final release, and there was apparently enough of it for the folks at Nomadio to exploit into a full fledged feature. That's now become Connectify, a free application from the company that effectively turns any Windows 7 computer into a virtual WiFi hotspot — letting you, for instance, wirelessly tether a number of devices to your laptop at location where only an Ethernet jack is available, or even tether a number of laptops together at a coffee shop that charges for WiFi."

hehe
dunno how they found it. but this is the little upstart that makes the new software that exploits windows 7 hidden feature of acting as a hotspot.

course that software may not work if microsoft ever patches to really turn that feature off in the OS |

IEEE 802.11 by definition is CMSA/CA and half-duplex.
No 802.11 product can simultaneously transmit and receive in the same band. A dual-band product may operate each wholly independently. |
