My two wire antenna (Main and Aux) was disconnected in my mother board.. can you tell me where part of motherboard should i connect the black and grey wire?

These antenna cables should be connected to the wireless card. How to connect them? It depends on the model of your laptop, but I think it shouldn’t matter.
You can try Main-gray, Aux-black.

I have a Gateway MA2 laptop and my wireless connection in network connections disappeared. I have looked in the device manager under network adapters and it only shows the 1394 LAN adapter. I cannot figure out how to connect using wifi without this connection. Any suggestions?

1. Try reconnecting the wireless card, maybe it’s not making good contact with the slot. Remove the wireless card from the slot and plug it back in. It’s possible that after reconnecting the card it will appear in the network connections.
2. Try reinstalling the wireless card driver. Download it from the Gateway website and run.
3. Finally, try reinstalling Windows. It’s possible you have corrupted software. Backup all personal files and run the recovery disc. Reimage the hard drive back to factory defaults.

If the cannot get it work, it’s either bad Wi-Fi card or motherboard problem.

I have a Toshiba A215-7422 and would like to upgrade the wireless card to the Intel® Ultimate N WiFi Link 5300.Will this card work and would I be able to get wireless N performance or will I have to install another antenna? By the way can another antenna be installed?

I’m not sure if the Intel card will work in your laptop, but Toshiba has an Atheros a/b/g/n card listed for Satellite A215-7422.
Here’s the part number for that card: V000090370. Google the part number and you’ll find it.
You’ll have to replace existing antenna cables with a new set. Here’s the part number for Toshiba antenna cables (a/b/g/n): V000100060.
The Wi-Fi antenna cables can be replaced. They are running inside the display panel and routed under the LCD screen. You’ll have to disassemble the display panel, remove the LCD and replace cables. The keyboard also has to be removed for that.

mini pci-e connectors came apart from wire. can these wires just be re-soldered to connectors or are they like an RCA plug w/2 wires (per wire) + and – ?

I believe they are 2 wires per wire. You’ll have to replace the antennas.
Same happened to me last week. I was fixing a laptop and accidentally separated the connector from the wire. I replaced the antenna cables after that.
