Is there a maximum length for Internet calls before their signal strength decreases ?

Th title says it all. I'm getting really frustrated with wireless connection for my PC.

The adapter's antennas are directly facing a wall and then there's another room to go before the signal reaches the router so The signal strength is just horrible.

I ran inSSIDer and the score was -75

So I finally decided you use wired connection. The length of the wires has to be about 10 metres for it to reach the PC. So would a 10 m cable be ok ?
