Are you using an ethernet cable and trying to get wifi? If so that won't work.
We had our second PC on wifi and I bought a 50 foot cable, snaked it to the next room to the other PC and got rid of the wireless. What a difference. Solid as a rock, never drops the connection and both PCs have the exact same speed now.

We started having problems because we have neighbors that have wifi that are as strong as the wifi in our house. When searching for a connection we see 2 new networks that are just as strong as ours one room away. It was confusing our computer, so we just got a cable and plugged in. It is so much better. And we know we're secure now.

Even though we had a password on our wifi, I'm sure it wasn't hard to hop onto our connection. We connected to our neighbors wifi with no problem so we just dumped it. Believe it or not one person's network password was "password".
