How to Increase Your Wi-Fi Signal
Tear off some foil in the shape of a rectangle, give it a curve and then place the foil behind the antenna of your router. This will reflect the wireless signals into your preferred directions.
If the router is mounted on a wall, you can make holes in the Aluminium foil and insert it inside the antennas as shown in the following video.
If you are away from your home base and want to connect to an unprotected wireless signal, this short video provides some great tips to help you do this. By using your cell phone, laptop, an ethernet cable or a salad bowl with aluminum foil, you can increase network availability and extend your wireless range. Now I can finally go set up shop with my laptop in that beautiful park near my house! Yay!
1. use your Ethernet connection which is nor a wireless connection,,,
2. wrapping up your cellphone want do any good to any signal ....
3. ... and for sure not by putting it in your salad bowl.
so if you really want to increase your wifi signal you can just google for "how to extend wireless range" and you'll get real ideas (common is reflecting back the AP signal by putting aluminum foil behind the antenna)
