There are many ways to boost wifi signal. Try hanging a router from the wall or placing in the center of the room. You could also try investing in an antennae.
I bought a signal booster from cellphonesignalbooster.us and it made my wi-fi catch full signals.
What it basically does is that its powerful antenna catches signal and passes it to phone booster which amplifies it.
Buy a wireless range extender
Depending on the make and model of the USB WiFi antenna, it can boost a WiFi signal range up to 1000 feet and some claim to boost the signal by four times whatever the current output is.
The best thing to use in order to boost your wifi signal is to get a wifi booster. Radio shack sells them for around $90.00.
You can purchase a wifi signal booster from Amazon.com. You may find a cheaper price at tigerdirect.com. This is a good way to boost your signal to the far corners of your home.
Technically it is possible to transmit a WiFi signal 1 mile because the record for the longest transmitted WiFi signal is 238 miles. In the real world a few hundred feet is much closer to the maximum that you will ever see and even then it is limited by any obstacles that are in the way. Maybe some day our WiFi equipment will get better but until then it will just be geeks with too much time on their hands sending WiFi signals long distances.
Hawking HWREN1 Hi-Gain Wifi extender works just like it says- doubles the existing connection signal… My large house has full bar signal everywhere, no complaints from me.
Only if your 3G signal is on. If your 3G and wifi signal are both on and if your within wifi, it will use the wifi signal (connection) first.
If your wifi router has an antenna that can be replaced i would suggest just buying a bigger better one off ebay. The antenna you have now is probably only a few inches long, get one like the one in the link below to really boost your wifi signal round your house.

Signal for what? wifi
A prepay phone can connect to a wifi signal as long as it has a wifi receiver and there is an available wifi network within close proximity to the phone.

No. There is no WiFi signal capable of going that far.
