Antenna Strength - (Telstra)

Does anyone know if its possible to boost the strength of the antenna (either by software or hardware)
I'm located on a mine site in remote West Aust where Telstra Next G is the only coverage we have.
I've found that out of all the my work colleagues, the HD2 has the worse reception of all. Comparing it to a friends iPhone he can get a signal in many places I get none, and once I've reached an area where I do have 1 bar (out of 4), he's usually got 3 bars (out of 5).
I've done a fair bit of Googling/etc but haven't really found anything. I've updated to the latest Telstra ROM (1.72), and that was no better. Also tried a couple of other ROM's from the HTCPedia site (eg Dutty's) but they were even worse.
Are there any software tricks to boost the signal? Can I get it modified to have a better antenna installed, or even have an external antenna connection fitted? I've tried one of those inductive antenna's that clips to the back but that didn't help.
Cheers

HD2 antenna
I have a similar problem and have fired an enquiry off to the guys at 'comnet' to see if a high gain antenna can be hooked up to a universal inductive cradle for my HD2.
I will only try it out if I can find someone who has got it working.

There are such things as local area booster relays, but, you would have to get one for the correct frequency and they are not cheap.
Try the latest release radio in the radio thread in the ROM development forum. Its the best so far.
Make sure its compatible with your ROM.

i tested USB Dongle with a laptop to all areas that I would use the mobile at high-speed, loads of places worked and then order a batch of HD2's, the signals are so poor on the HD2 that made me anoyed.
I do have vodafone's suresignal which helps, but not the point.
I have wondered if the metal plate on the back is being a problem, but not tested any combinations yet

I've tried an inductive booster (~30cm aerial), definitely makes it better, but still worse than other phones.
With removing the metal cover and using the inductive aerial its a little better again, but still not as good as other phones.

Most the phones I have had have lost reception at the back of my local Coles, including a Blue Tick SE W705... But not the HD2... Not only do I keep signal I've had several calls there while shopping...
What phones do your mates have?
Maybe its a band issue...

Maybe because the OP is in a mine site? It may hinder the reception, I dunno.

I'm on a mine site with only a Next G tower, and its been specifically positioned so you can't get reception in certain parts.
However, standing side by side with a few other phones, I'll get nothing on the HD2 (sometimes even with the inductive aerial) and mates iPhone 3GS will have a bar, as will another mates Nokia 6120.

[HELP] SGS2 not receiving signals

Hi
This past Saturday, the 3G signal strength in my area was pretty weak due to heavy rains and thunderstorm. So I connected the CRC9 3G antenna to my SGS 2 that I used with my 3G modem. Later on I disconnected the antenna and then I found out the phone was not receiving any signals. On further investigation found out that if I went outside the phone was receivng signals but juts a bar or two at max. Tried the same sim in my friends SGS2 and it was receiving full signals.
After this I tried flashing different roms, kernels, modems etc but to no avail, the situation did not improve. Now the only way I can receive signal in my phone is by connecting a thin copper wire to the hole of the CRC9 connector at the back of the phone.
The phone was purchasded in UK from CPW, hence does not carry local Indian warranty.
So whats the best thing to do? Please help me.

Tried factory reset?

Yep tried hard factory reset.
Tried all possible modems vers, things work a bit better with KF2.

so guys can anyone help me?

Would you be able to put a different networks sim in, to see it it is just the network being faulty, or a hardware problem. Maybe if you have a different phone you you can see how good the signal is in that and compare the two, to see if it is again hardware or networks.
If it is hardware, there is really only a couple of things to do, take it to a phone repair shop, or get in contact with Samsung and pay them to fix it. I know that a couple of weeks ago in the uk, I started getting only 2g connectivity and it kind of scared me a bit, thinking I had damaged my brand new phone. It turned out the networks 3g was down in my area for a couple of days.
If I have helped, please hit the thanks button (please) >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>

I had the same problem, I put in a different sim and it worked fine, for some reason it hated the orange network in the uk, but seemed to work well on o2.

Help! Dropped my HD2 hard. Wifi error!

So it fell on the glass screen hard onto the floor, but not a scratch! BUT WLAN isn't working anymore and shows "error" in settings now Everything else including bluetooth works fine.
Any ideas to what/where the problem could be (likely hardware)? Easy to fix?

Probably hardware, , dropped mine 18 months ago and lost GPS. The fact you are getting an error would suggest actual damage to the wifi hardware, rather than a disconnected aerial.

There is potential for that but read this: http://forum.xda-developers.com/showthread.php?t=1190180
One of the sets of contacts is for wifi.
Hope it helps, worked for my radio signal

Thanks for the replies. So if the wifi chip is actually damaged is it possible to replace it? Can I buy a new one from anywhere?

If i remember it well, the wifi chip is On the motherboard so I don't think it's possible to replace it

not a chance, the logic part of the wireless subsystem (wlan, bluetooth, gps etc) is located inside the qualcomm chip (the one we usually but improperly call the "cpu").

[SOLVED]no mobile data after screen replacement and weak reception

Hello everyone,
I'm having isssues with mobile data on my N4 after I replaced my digitizer and lcd screen. I dont have problems with WiFi, I also can call others, and others can call me, same with SMS's, but I can't access the internet. As I disconnect my WiFi, signal bars turn orange or get exclamation mark(tried on both kk and lollipop). It shouldn't be an issue witg the antennas, because SMS and calls work(wich also use cellular). Could be wrong though.
I'm also having weak singnal. In my area there is usually sufficient coverage, but in the moment I one bar indoors, 1 or 2 bars near windows(enough for calling, but too little for mobile data), but I used to have 3-4 bars indoors. Any fix to that?
Any help is welcome.
Edit: got access to internet by readjusting APN(duh). Never thought of that beause it usually does it itself.

Are you sure APN settings are correct ? I'm using TELE2 (Lithuania) and default apn settings are wrong - I need delete proxy server and proxy port from apn to have working mobile data ...

Yeah, I thought about that right after posting, and I got that fixed already,(I have also TELE2) but I still have reception issues. Anyway, thanks for participating.

for weak signal first what I would check - coaxial cable from mainboard to gsm antenna (plastic part above usb port) and maybe antenna connection pads.
have you tried 2G mode ?

The cable seemed fine to me, and the pads were okay. It might be just me, but it feels that the reception is getting better. I'm having almost constant 2G now indoors(before I almost had none).In 2G mode almost nothing changes, exept that it doesn't get occasional momentary 3G, like it does in 3G preferred mode.

I was wrong about the reception. Now it comes and goes absolutely random.

Problem solved. During the digitizer replacement I removed the electrostatic discharge tape. Replaced that with the insulating tape and now works fine.

Hi,
I've same issue, everything else are working fine but I get very low signal or no service at all. Where is this tape located?

It would be REALLY helpful if after you solved it, you could tell us the exact location, so any other person out of 7 billion people on earth, could solve it, including me.

First, I only thought at the time that it was solved, however I was wrong. I have reception only near cities.
Second, I put the tape over the coaxial cable and covering some of the battery as well.

G2 Very Weak WiFi

HI. I had this WiFi problem since I bought the phone like 6-7 months ago.
My previous phone was a Nexus 4. It had good wifi reception. From my apartment I could find like 6-7 routers with +2 signal bars.
My Lg G2 sees only 3 routers, mine and 2 others that are at 1 signal bar or sometimes no signal. I tried to flash other basebands but no improvment. I tried flashing other ROMs.
I now tried to lift the little conectors on the back cover and put a little piece of paper under so i'm sure they connect (i don't know if that's how wifi works because it's working the same with or without the back cover).
What else should I try? Is there something to do or every G2 has signal problems?

I might have a solution for you...

I had a similar problem with my G2. The old phone (Optimus 3D) had good and strong wifi signal. With this one, from the first day to connect to home network, I had connection problems and all I had to do was to set to one network mode (and only one - I use G), on a single channel (give it a low one - 1 to 6) and a 20 Mhz band channel. And guess what: I can have a clear and strong enough (plus stable) from down the street, while my flat is at the third floor.
Please try to modify your modem/router settings as stated before and let me know the results.

My router works fine. I have it on G/N 20Mhz Channel 5. I work installing internet antennas on top of buildings so I would like to access the routers from far away.
Another question. What's the purpose of the gold connectors on the back cover?I have like 3-4 pairs. My wifi, network and gps work with or without the cover. No difference.

You must have only one type of connection. Or at least in my case is so. I have only G, not mixed one. As for back cover connectors...I have none. Stock back cover, gold edition of D802.
