I can not get signal from my router in the back room but can about 20 meters/65 feet up the house so would i be able to run a 20 meter/65 feet usb cable with a network adapter attached to it and get signal that way. I am aware that high speed usb connections are limited to 5 meters/16 feet but i dont know if a network adapter is included in those limitations. If it could even give me half strength i would be happy at that or if you have any other solutions please feel free to voice them.....Thanks in advance
Answer
USB won't go that far.
Wireless signals are affected by many factors including wall density, electrical interference, directional antenna range, etc.
All of these factors will affect your actual wireless range. As wireless connection quality varies the connection speeds are renegotiated. The connection may start at 54 Mbps and end up at less than 20 Mbps.
Just because a particular wireless router works good at one location does not guarantee that it will have similar performance in a different location due to variance in the factors listed above.
You should try to centrally locate your wireless router or gateway up high and away from dense walls and electrical and 2.4 GHz wireless interference such as microwave ovens, cordless phones, baby monitors, etc.
There are solutions,
The best solution is to run a Ethernet cable to your router. Pre-assembled CAT5 Ethernet cables are relatively inexpensive. Ethernet can be run up to a maximum of 100 meters.
A good quality 50' CAT5e is about $9.50 http://www.amazon.com/gp/product/B001W26TIW/ref=as_li_ss_tl?ie=UTF8&camp=1789&creative=390957&creativeASIN=B001W26TIW&linkCode=as2&tag=excharge-20
If it is not feasible to run cables you have other options such as powerline network adapters You plug one in by the router and one in the room where you need access and connect them to the devices with standard Ethernet patch cables. http://isp1.us/reviews/netgear-xavb2101-powerline-adapter/
The network signals are transmitted over your existing home electrical wiring which will not be affected by wireless interference.
However, if you need the wireless mobility there are various other ways to extend a Internet connection to areas with a weak wireless signal.
Devices such as wireless extenders that can expand your wireless range if need be. http://www.amazon.com/gp/product/B004YAYM06/ref=as_li_ss_tl?ie=UTF8&tag=excharge-20&linkCode=as2&camp=1789&creative=390957&creativeASIN=B004YAYM06
The wireless range extender receives weak wireless signals and repeats them to extend the signal range to greater distances. Some models include 4 Ethernet ports in addition to the wireless radio.
Good Luck...

How do you connect a sensor to a radio transmitter and programming it to transmit one task only?
Q. I badly need advice on how to do this for our science project. Our project is to monitor garbage through radio waves and sensors... the problem is that how do we connect the sensor to the transmitter and how do we get to program it to transmit the garbage levels... and one more thing... What Type of sensor do we use?
Answer
Sounds like a cool project that's best if broken down by section.
The key to a successful science project is to keep it as simple as possible while demonstrating one or more concepts. Cost will also be a concern. The trickiest part will be your radio link since there are all kinds of government regulations about what you can and cannot do especially at the unlicensed level. Instead you want to find a transmitter and receiver that already work well together over short distances. Garage door or car alarm remotes can be difficult to work with on the receiver end. A pair of cell phones might work if you have unlimited minutes to burn. Low power toy walkie talkies might work if you had a way to push the transmit button for short intervals. An iPod type transmitter and FM radio might work together. So would a couple of WiFi enabled laptops networked together through a wireless router, but now we're getting complicated again. A battery powered wireless baby monitor just might be the ideal solution.
Note that most of the transmit/receive link possibilities mentioned above involve audio. You'll want to use your garbage level to control either the frequency or volume of the audio you transmit. Volume is probably the easiest since you can use a relatively simple meter circuit at the receiving end to measure it.
One of the nice things about a science project is you can control many of the parameters. Use a small waste basket as your garbage can and use something that packs relatively uniformly like tennis balls or crushed aluminum cans as your garbage. Now all you need to do is weigh them to know how full the can is.
Place your garbage can on a plywood platform hinged at one edge and held up by springs. Get one of those slide style volume controls and rig it so that the slide moves as the platform edge moves under the weight of the garbage. Adjust the tension and number of springs as needed.
You'll need an audio source such as a simple oscillator or a steady tone saved on an MP3 player. This feeds the volume control on you platform scale which in turn feeds your garbage monitor transmitter (in place of the microphone).
The volume at the receiver (after substituting a meter for the speaker) will track the weight of the garbage. Lookup LM3914 for circuits that use LED's that you can label from empty to full.
I'm assuming that someone in your group can handle the basic electronic connections.
Now go get that A.
