The range depends on a lot of things. Antenna size and gain, the materials used to construct your residence, and aany local phenomenon that might create EM interference.

Under ideal conditions, you can probably expect around 100 yards. Under more realistic conditions, 50-100 feet for a reliable signal.

If you have lead in the paint or lots of steel in the frame of your domicile, or maybe there's a power line running over your house, anything that will cause EM interference will greatly reduce your range.

Drawbacks

The major drawback to wireless is that it's a half-duplex means of communications. You can only send OR receive at any given time. Most people won't really notice a difference, but this limitation will cause wireless to always be slower than wired.

In addition, many common household appliances can cause problems with the wireless network. Cordless phones operating in the 2.4GHz frequency range, microwave ovens (which cook things using a frequency right around 2.4GHz), poorly shielded electrical wiring in the walls, and dozens of other things can cause problems.

While not a problem for 1-2 system networks, wireless is also a shared bandwidth medium. If you have two computers connected, they each get slightly less than half the total bandwidth, and each subsequent computer degrades performance even more.

There's also a wide variety of really poor products out there. I've personally had very bad experiences with every piece of D-Link equipment I've ever used. So, you'll want to hit multiple review sites to see which products seem to fare better than others.

Thanks... That is a very detailed response to my question.

I might have to have my cable company just install another drop in my upstairs floor or just wire it myself
