Greetings since Colombia
----------------------- Introduction: -----------------------
My HTC Sensation 4G, like the majority, suffers of the terrible Death Grip problem/issue. The signal decreases both wifi and mobile signal.
I've founded some advices, since change radio version, including many radio/Ril combinations... Also, aluminum foil (initially it doesn't convinces me, at apply it... neither)
Some day in a free time, after make some philosophization I've get to this conclusion: use cable.
Yes, CABLE.
As you know, our Sensation has its antennaes in the back case, and if we remove that case out signal is over.
This trick consists in strenght the Wifi and Mobile signal, right this our signals stay alive although our back case is out.
If we put again the back case, the signals become more strenghten.
----------------------- What we need: -----------------------
Our phone, slim and bare cable, pliers/chisel/pin, insulating tape, and so much CALM,
----------------------- What to do: -----------------------
We locate, please, the antennaes position.
Now we cut two bits of the cable.
According to the images situate the cables.
Finally, join the cable with the insulating tape.
You can make this with the phone turned on.
----------------------- Some considerations: -----------------------
In wifi photo (near to camera) preferably, join the cable to first pin (number 1). It doesn't effect if connect to the second pin, and it could function if connect it to both.
In mobile data photo (near sim/sdcard) preferably, join the cable to second pin, if you joins it to the first one there's no effect.
If we "cap" the antennaes, only one or two signal lines can be lost, but the signal can be complete in few seconds.
----------------------- Some advices: -----------------------
NEVER join both cables, it can provokes short-circuit.
NEVER join a cable outer to battery pins nor to battery itself.
You can activate the "Better wifi performance" option in wifi menu.
----------------------- Conclusion: -----------------------
This method could improve the wifi and mobile signal. Is recommended use a correct radio, and a matching radio/ril, etc.
I hope this method can help you. I wait your comments and your THANKS!
Thank you very much.
Wow this looks very fascinating, I will have to try it. What is the risk in doing this? Are there any negative long-term effects?
I did similar to my phone, as I found the reported signal wasn't as good as on my desire HD.
I think there's a slight improvement, but I couldn't say I've tested it scientifically. In my office the signal is quite poor, after doing the mod I found the signal doesn't drop out anywhere near as much, but I can't say its increased call quality.

Yes, the major risk is that the mod could become into a short-circuit ONLY IF you JOIN THE CABLES each other.
E.g. join the mobile signal cable with the wifi cable.
Negative long-term effects?
Surely NO. There aren't negative long-term effects. One month ago I've made this trick and I never experimented negative effects.
---------------------------
Remember, this trick increases a (much) bit the signal (mobile and wifi), ergo, in my case/opinion there's not signal drops with this trick.
Thanx for the tips !
i tried both mod and i don't get a good result for the wifi (long/short cable, different paths left/right) but the gsm signal is really better !
no more signal drop in my apartment !
Although a good idea in theory, I have tried it, and although it doesn't improve signal strength by a LOT, it improves at least by a bit. Of course, others may have varying levels of success, if you use different wire, the method of connection etc.
However, it is quite possible to damage the antenna pins, so you have been warned.

Exactly, you're right.
In my case I've improved the mobile signal and the wifi.
It's necessary to 'drive' correctly the pins. Situate of a correct form the cable in the pin. And NEVER join the cables each other (wifi cable with signal cable, etc)

Also, the signal strength icon is totally UNRELIABLE as a true indicator of signal strength, unless you change it to display the actual measured value in units ASU. (Which can then be converted to dBm, and you can work out the gain of your antenna, relative power etc...)
did, the guide, mobile is awesome i download with over 1.5 mbs but wifi is very poor, first i had max wifi now only 3 lines.
video guide would be nice, if possible :fingers-crossed:

Yes, after several days of testing my trick I may accept the following results, also according to your comments:
* This trick improves, I can say, much, the carrier signal. There's no drops!
* But wifi signal is improved a (little) bit. I've discovered that the culprit is the Broadcom chip (if you cap the wifi antennae with/without back cover the wifi signal is OVER). In my case the Wifi isn't stable but the signal improves 1 or 2 lines.
In the following days I'll try to improve the wifi trick, in order to know if my trick makes effect OR it's a factory problem.
Please, give me thanks to my post, if it helps you!! Everybody!!

Great Job men
Im seems very difficult but if you do it right it works
at leats in my case it works... not whit the wifi signal is the same but whit the mobile network it get a
big boost...
thank you very much really too much
i cant give thanks many times to the post but im really excited and grateful (xd)

Jajajajajajaja... Yeah, it requires so much CALM and patience
My theory is that the Wifi chip is (a bit) defective, therefore my trick doesn't make so much effect on Wifi-side.
But in general words, I'm glad that my trick made effect on your phone.
Greets!
can we use copper wire?
what type of wire you're using?
from the pictures it looks like a threaded thread to me :/
is it a conductive wire?
I will give this a try. I have low signal since i changed the stock T-Mobile radio (which I can't find to flash again), tried many but the same.

Jjajajajajaajjaja .... The cable is from an old AC-to-DC adapter, it's like conductive wire.
At making the trick, make sure that the cable you use is thin, in order to the back cover puts fine into the phone.

You can try to match Radio and RIL through GetRIL app.
Otherwise, in this post (http://forum.xda-developers.com/showthread.php?t=1202867) there are many radio versions.
You can try several radios and rils and see which of them is better for you.
PD: It seems that you have the HTC Sensation TMOUS (T-Mobile), find in that post the "TMO dish".
In general lines, follow the instructions.

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.
The connectors are for the nfc chip

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?

Always wonderd

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...
Sent from my Nexus S using XDA
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
So my phone is useless for controlling my RC AR Drone then?
Wifi signal is crap, I'm pretty handy with electronics but I've read that even the chipset they've used in the NS is rubbish... Does anyone know which reasonably new handsets have good wifi range? My old N1 was pretty good but it's just too old.
if someone can confirm that it's the antenna and not just a sh*t wireless card then i'll have an attempt at replacing it with laptop antennas.
A little question, it won't be easier to improve the antenna of the WiFi router, instead of the mobilephone's one?? You can do that simply, by putting a can on that antenna (Search on google for the tutorial, it really worked for me).
Regards
Hmm.. I think you can.

Check the Battery Cover, and you will find that. But it's not sure
Wooooow Nexus S have WiMax
There's definitely something wrong with the Nexus S 4G's wifi. I have to be next to the router to be able to use the wifi. No other device, phones, tablet, notebooks, etc has an issue. Odd that others are having the same issue.
Did they forget to connect the wifi antenna?
just upgrade your phone maybe? and your antenna is somewhere in the back.
I found that the WiFi on my NS went to **** after upgrading to JB.

Hi guys I have a usb wifi reciever, and I want ti extend the range, I have a flat near my house with wifi and its about 400metres away, I wanted to know if some how I can extend the signal reception to pick up this wifi, the usb reciever has a small antena that can be taken of, could I attach coaxial or other kind of cable and attach it to my tv antenna or a satelite dish I have to pick up sky? Please aswer me, I think this is the right section, for me this question is a big thing because ive been without internet for 9 years know, I only have my phone! Thanks!

An antenna is made for a specific wavelength, there is some physics behind it so you can't just put a big antenna and expect it to work. What you can do is extend the range of the emitter. You can do that either by getting a high gain antenna or a directional one.
I've also seen people receiving wifi from a distant router with a directional receiving antenna, but it has to be especially made for wifi, you can't use a tv one.
Also take in consideration interference. If there are lots of objects and other devices operating in the wifi signal range between you and the wifi router that signal is going to lose its quality so even if you'd get 100% signal, it might get jammed by all the interference.

Thnks for the clarifications, ive seen this antena on ebay but dont know what the range is! Any idea?, what u said about directional recieving antenna, whats that? Could u please upload some pics? Thanks, I dont think interference will be a big problem because I live in a rural area! Thanks for your aswer!
Press thanks if I helped!

That looks like a cheap antenna. I don't think anyone can tell for sure what you need to receive a signal from that far away. There are so many unknown things you need if you want to make the calculations.
The gain of the antenna is used to calculate how weak the signal can be and still be received.
Think of it as hearing a guy scream at a distance.. you can have an amplifier next to your ear, you might hear him if it's a directional amplifier but you will also hear everything that's between you and him. Although sound waves are different than electromagnetic waves, you can think of it like this to understand why the long distance is such a big problem.

Thanks for taking time to aswer, the distance I was hoping to pick up is about 450 m no more! Will interference still be an issue?

Try this: http://www.freeantennas.com/projects/template2/index.html but I don't think this will work at that range.
If your usb wifi reciever have an external port for antenna, try to connect an axternel antenna to increase the range. This may work. Or you can buy a cheap wifi router to bridge with the one existing in the flat.
And YES, interference may be a problem!
Hello.
I had the Sensation for almost a year now, thanks to all the developers who help make this POS still usable.
There is a problem, or so I think. The signal quality decreased over the last month or so. I used to have all the bars at my house and 2 bars at school. Now I get 2 bars at home and nothing, not even edge at school. The connection is also very weak in terms of stability, I used to be able to browse the internet while riding the subway (above ground), can't do the same now, it will drop the signal.
Changing roms didn't do anything, nor did the flashing of the different radios. Currently on stock and 3.32, S-off.
Is it possible that radio module was damaged somehow which resulted in poor signal reception?

Remember that our Sensations (the majority, the mine for example) have the Death Grip problem.
... backward of the hard case there are some gold pins, these are the antennaes (GPS, wifi, radio/signal...)... in your case You can try to "clean" the pins of the signal (two gold pins, D/E ones in the attachment) with an eraser.

Well aware of death drip, it never bothered me unless I did that on purpose.
I tried cleaning contacts, to no avail. I've even tried different back cover from another sensation (which gets signal), the other person was able to get signal on his phone with my cover. Guess it's not the contacts.
Any thoughts?
Ummmmm.... the problem seems to be hardware issue (when flashing new roms/radios/ril doesn't function)

Great, now I can get something new and still have clear conscience
My shiny new PiPo U8 has terrible WiFi, and it can only see the router within a couple of metres. Things improved when I set the router to 5GHz. Before that it was around half.
The tablet is in an all metal chassis which seems like an oversight. However, I find it hard to believe the company would release a tablet with such poor wireless performance.
Is it likely that a firmware update could improve things? I think I've read of such things before.
Thank you
Do you have that problem only with that router? have you checked with another wifi source?
If you have landline wireless phones at 2.4ghz they can mess some wifi adapters as well, check that.
it can be due to a miss connection of the wireless antenna inside the device, there are many possible causes.
Also it can be related do kernel/driver issues on your device, that would be solved by some mods.

Same problem at work. Earlier all the guys with Android phones used WiFi Analyser to show the local WiFi networks. They each got over a dozen and the main one was at -90. My tablet got the same network one at -65 and no other networks. Turning the tablet could add or loose around 5 units.
I suspect it may be a badly connected or badly positioned antenna. I've been trying to find out how to open the tablet up in order to check. Apart from this major issue, it seems like a great device and a real bargain. Elsewhere online there are reports of very good WiFi performance with this tablet.
5 units as in network strenght or 5 units of visible APs?
You know that -65db is actually better than -90db right?
Check if your device is at 2.4ghz Wifi band, and not at 5Ghz as most of the public wifi router are 2.4ghz.
Yep, the antenna wasn't connected.

there's a setting on the phone which you can choose 2Ghz, 5Ghz and automatic. choose automatic.. if it doesn't work reset your modem and press the WPS.
Unfortunately some tablets are designed poorly where they impair WiFi/GPS/3G signals. A prime example is the Asus TF300 tablet.
Try using some apps in the appstore like Wifi Booster
Hmm, I've already answered this. Does no-one read topics any more?

Hey at45, I also took my u8's back off tho check the antenna. It was connected and while the back was off it got great reception. Now to my question, just to be sure the antenna is the small co-axial cable coming from near the power button and going to the area by the speaker, correct? Also does anyone know where I could get a stick-on antenna that I could maybe mount on the back and connect to my antenna lead? I think this would turn this really good tablet into a great one.
I do realize you've already answered this, I was hoping for some insight on the external antenna notion I had
For me wifi is medium to good - not as good as the laptop but not as cruel as some others described it - so there might be different versions.
If you're already as far as attaching an external antenna, why don't you cut out part of the cover and replace it with some nice piece of plastic? Might actually look better than an external antenna...
Hi everyone,
I have recently cracked my screen and replaced it myself using youtube tutorials. I have (somehow) completed the task although I had many problems with the two side cables (black and white antenna cables, I hope you know what I mean as I don't know their proper names). Specifically, I wasn't able to slide them down the channels intended for that and at the same time I wasn't able to connect them properly in the jacks were they need to be plugged in. I thought I have somehow did it but it seems I did not do it properly as I do have frequent ups and downs with the network signal, I lose it constantly in places where I used to have full network signal and I can't reach LTE at all, there's no connection at all when switched to LTE. There's signal only when 3G is ticked in settings and internet signal remains to E, rarely if ever moves to H.
At the same time, Wi-Fi is good although I feel it worked better previously, but that can only be my imagination working.
So, I think it has something to do with those cables, as those were my main issue during reassembly. Is there any advice anyone can give me. They don't seem broken, but I can't fit them in the channels and in the jacks properly. Would it work if I put something like a sticky paper in the channels to hold the cables down. Also, is there any trick for connecting them in the jacks or I just need to be precise?
Or, is the problem something completely different?
Any advice would be much appreciated as my phone is rather new and I absolutely love it.
Thanks in advance
Those mini-coaxial sockets can be a bit harder to push in at times - just get a pair of good quality tweezers , get a good grip on the connector and push it down with some other tool. I can guarantee it is going to go in . If they don't make good contact you are either going to get intermitent network , or a very week network signal .
