ZTE P729V San Francisco aka Blade: Poor WiFi Reception

If you happen to notice that your ZTE P729V San Francisco GSM or Blade (in USA) has a very weak and unstable WiFi reception, you are not alone.

Although in general pretty pleased with the device, the WiFi was not stable and had a very very poor reception. Less than 1m /3ft away from the router resulted in less than 2 bars. (<50%) 

This is what I did to improve the WiFi reception:



1 Pre-emptively: download a little free application from the market "WiFi Analyzer" (Thank you Kevin Yuan for developing this app)

2 Test your current reception strength on your device

3 Power off the device

4 Pry off the back cover

5 Prepare 2 strips of scotch tape and 2 pieces of aluminium foil. (sizes you can see in the image, try to aim closely to that size for best results)

6 attach the strips of aluminium foil covered with the scotch tape carefully on the phone antennas as shown in the pictures. Be very careful you don't short any contacts.

7 place cover back on the phone

8 Power ON the device and test the reception now.

If you do it right and made the strips the right size, the WiFi reception improves drastically.Actually the ZTE San Francisco now has almost the same reception as my HTC.


I hope it works for you also.
