Default Improve Nexus S WiFi antenna

Hi everyone!

Is it possible to improve the wifi antenna of my nexus s? With my last nokia it was possibile by salding an extra copper wire, is there any similar mod that I can do on it?

Thankyou..

not 100% sure but the antennas are in the back cover along with the nfc chip.

If you remove the back cover, you can see the connector.

Default Improve Nexus S WiFi antennaArrow

I have just bought my Nexus S and am experiencing a weak wifi signal. I normally get 3 bars on all other hardware in my bedroom but am only getting 1 bar which occasionally goes up and down to 2 bars. When I am 3 meters away from the Wifi access point i only get 3 bars out of 4. All my other hardware gets full bars. When i am 6 meters away from the access point I have only 2 bars showing for wifi.

The wifi signal icon seems to fluctuate alot. Does anyone else have a similar problem?

First and foremost bars don't mean anything really. The signal strength typically is better but what matters is the SNR (signal to noise ratio). This can by typically improved by allowing your router to switch channels automatically (from the default 6) to find the most open one. Adding your own antenna is a bad idea and it likely will make the problem worse. Those antennas are precisely designed (exact configuration) for that ranges of frequencies, adding wire will ruin those characteristics.

With GB the wifi signal was completely awful...but now with ics wifi isn't that bad....I'm not having a lot of issues now...

I haven't seen any difference in wifi signal between GB and ICS: in both of them I get 1-2 bars while my ipod gets full signal. BTW it isn't a good idea to mess up with your phone's antenna.

Most probably it is not.

WiFi antennas on theese devices can even be SMD only (trying to improve is waste of time), or "copper plate sticker" type, ussualy stickered on the internal back cover.
I've been messing around with the second type on crappy chineese WiFi phone - I've added a tiny connector used in mobilephones and connected simply a piece of coax wire to make a dipole. After few changes signal finally got a bit better, but also because in original it was really poor.

If there is a sticker-type antenna, it is theoretically possible to change antenna quite easy. In practise, you will hardly get it better because you can't just put some wire in and done (well, you can, but it will be like wining a main prize in lotery if it gets better). The wire should have right size, right shape and must be on right place. And milimeters makes a difference there, so have fun

Most likely it can get better only with some kind of external antenna, but you could hardly use your phone as mobile then

Easiest way to tune-it-up could be disconnecting the original sticker and connecting a flexible internal notebook type of antenna, but even that will probably be too big to fit inside - it must not overlap another antenna. And that's not the only rule.
Even if it does not overlap anything, it can interfere with other circuitry or Tx-devices. Bluetooth works on almost the same frequencies as 2.4GHz Wifi, for example. It's a piece of science theese frequencies, actually

I'm absolutely NOT thinking of trying to tune it up on my LG O2x, coz I know it won't be better
