bad signal related to the radio version?

So I decided to Root, S-Off and flash Coredroid v4.7 on my Inspire, but I leave it with the stock radio (12.39.60.19P_26.06.04.06_M), but the signal seems pretty weak even on places where my Nexus one was at full strength my Inspire seems to only be able to grab 2 bars at much, and the WiFI connection seems week too, on my N1 I used to be able to get full signal from more than 20 meters, but my Inspire seems to lose it after 15 meters.
I read some posts and other blogs/forums and some attribute those issues to the radio version, so I hope someone can give me an opinion and tell me if I should Update the radio and to which version if so.
Thanks in advance.

Try this
For phone signal, try *#*#4636#*#* in the dialer. This will bring up a screen that has 5 options, I went to phone and scroll to the bottom. Under the preferred network I changed it to GSM only as its an AT&T phone anyway, I was getting 1 or 2 bars at home and was missing calls left and right. after setting this, back out and shut the phone down then restart. I have all 4 bars now. It would also eat the battery, mine was on WCDMA preferred and I think it was searching for that signal constantly. There is a screen for wifi also but there is nothing adjustable there.

Odd that it would have WCDMA preferred as default. I just adjusted this as well and it improved the signal in my office. Good catch.

Gsm only does not work for me, my lame carrier runs on gsm but their mobile internet runs on their 3g so I need to connect to both. Setting it to wcdma/gsm auto seems to have improved the signal

You saw this option in the phone menu after dialing *#*#4636#*#* ?

Hey all, I'm on AT&T running radio 26.06.04.06_M. Any specific recommendations? GSM/CDMA Auto (PRL) seems to give me the best service based on bars, but that doesn't necessarily mean much (I'm on an HSDPA connection with 3/4 fluctuating right now).
Also, I think I might not have HSUPA enabled with this radio, I'm only getting .56Mbps upload and around a 2.79 download (Whereas on standard 3G with my old iPhone I typically pulled around a 1.2). HSDPA is without a doubt enabled and it shows that I'm connected on that network, but is there a better radio I should try out?

Thats what i thought and when I tried that it only gave me an "E" signal so I went back to how it was WCDMA

Nice just changed mine and full signal now. Thanks guys.

3G internet does not work - although it does say H

My HTC Desire S seems to be connected on the Internet on 3G (H) but nothing comes through. The 2 arrows also blink but the connectivity does not seem to take place.
If i turn WIFI on it works and when i switch off WIFI - the internet get stuck
I have done hard reset, restored to factory settings and problem persists.
I tried the sim card in another phone the and internet seems to work there on 3G suggesting it is not a network or sim issue.
I wonder if there is any setting that needs to be rectified.
Any idea?
Thanks

what rom/kernal are you using?

You've already tried most of things that I'd normally suggest, so don't think that I can help very much.
Sounds like it could be APN issue (which I now little about), where do you live and what network are you on? As this will help others to possibly assist further.
Does your network provider have the function where they can send your phone network settings, if so possibly try this?

if it doesn't you may have to change to a different provider

[Q] Poor signal GSM/WCDMA auto

Im looking for some help to try and resolve the poor signal i have on my handset.
The problem is, at home-
-if im on GSM only (settings-Mobile networks-network mode) i have no 4-5(FULL) bars signal no problem.
-If i am on WCDMA i have no signal-1 bar.
-if i am on GSM/WCDMA auto i also have no signal-1 bar.
So what i am asking is- does anyone know how or where to alter the threshold for when the phone switches from GSM to WCDMA when in a low WCDMA signal area. I think the threshold is set more towards WCDMA and i would like to at least fiddle with the values to make it more usable.
I could just leave the phone on GSM but i lose out on high data speeds if i am in a good signal area.
Also for reference i am in the UK on O2. I previously had a desire and never had signal issues. I have also tried a new back cover on my phone to check that the anteneas were working- and it was the same with the other cover (genuine HTC not from fleabay).
I have also tried a few different roms, Different radio's & matching rils and i still have poor signal so this is my last idea really.
Any and all help with this issue is much appreciated.
Thanks

What type of case do you have ... That can make a big differences man .... In poor signal ...

i dont have any case on!
I have since discovered, i went into the phone config secret menu (*#*#4636#*#*) and the network selection was WCDMA prefered. When i compared this to my girlfriends samsung galaxy W (stock) her's was set to GSM/CDMA (PRL) so i swaped mine to match her's and it has helped a bit but the setting seems to revert back to WCDMA prefered when i reboot.
Does anyone know where or how to set this permanently? Built.prop or something?
Thanks

I struggled with signal I bought a case mate protective cover for the back, and from time to time I stretch the pins under the battery cover, my signal is pretty strong normally get 3-5mb down speed aswell, wcdma preferred is the right option IMO, have you tried your sim in another phone? Sometimes sims need replacing

# Default network type.
# 0 => WCDMA preferred.
ro.telephony.default_network=0
Can anyone tell me why, if i change this value using es file explorer to
ro.telephony.default_network=3
it is still WCDMA prefered after a reboot. i even tried wiping cache and dalvik?

Might be an issue with the radio. If you are on a custom ROM, make sure you flash the recommended radio.

Same problem
This dude(beady) has literally given detailed description of the problem im facing aswell..
-good network in GSM mode(only edge no HSDPA)
-very poor network in WCDMA mode(HSDPA) with a lot of drop calls ...
im not rooted..In India Dehradun on Vodafone with Samsung Galaxy S3(pebble blue)
is it a hardware problem??..software problem??
please help..i need good data speeds with a good network to take calls aswell(what phones were originally meant for ..)
what to do..nobody still seems to have given substantial answer.

Have you tried the generic ICS radio/ril? I know you tried different radios but have you tried those?If you want you can change radio /ril and find one that provides a better signal. Radio /ril is something that you really have to find out for yourself as to which one is best because we all live in different areas and our signals will be different. Best place to start would be generic ICS radio and ril . They have several different ones available. It will take some experimenting on your part to see which radio and ril files will provide the best signals for your area. This is a option. I've done this myself. I was lucky, the first radio and ril files I flashed Madre a great difference for me. But start out looking in the generic ICS radio / ril files.you should have success there. Remember to flash BOTH radio AND ril. The ril is flashed the regular way , the radio is flashed like pg58img file through bootloader. Also remember to DELETE the pg58img file after it updates or it will continue to try to update over and over. Hope this helps! Best wishes!

Try this, on dialer type in '*#*#4636#*#*' without the quotes.
Click Phone Settings.
Select 'GSM Auto(PRL)' under the list to choose from.
Don't touch anything else.
No reboot required. A reboot restores what you've done. So, if you have more problems then reboot.

Dropped Connection to Network Problem

my phone will drop connection and then not reconnect. no voice, no data. (wifi still works)
what I've tried:
1. Different radios/firmware
2. different roms
3. different preferred network types
4. switching airplane mode on and off
what I haven't tried:
1. different sim
2. calling tmobile for suggestions
What else could cause this problem?

it could be a hardware issue

Hello,
I have the same issue than you !
I am facing issues such as call drop and no 3G data connection in some area in my region since I have 5 signal bar and H letter displayed (HSDPA connection)...
I have found a workaround consisting in:
1 - Switching to GSM Only mode (2G Only)
2 - Desabling Mobile Data Connection
Then it works, I can pass and receive voice call ...
Regards,
Nino

I'm new to the Sensation and having the exact same issue.
Followed the stickies in the Dev section to S-OFF, root and bypass SIM lock and then once the SIM card is inserted I get only GSM and no data.
If you use *#*#4636#*#* in the Dialer and go to Phone Information do you notice that it always switches to WCDMA preferred? I change to GSM/CDMA auto PRL like all my other Android devices (on Rogers Wireless) and it disconnects, reconnects but only for GSM and no data. It sometimes says it's connected to EDGE or HSPA but no icon at the top right and then it reverts back to GSM.
I have also tried flashing virtually every firmware, ensuring that the radio and RILs match (I had an HTC Desire Z so the HTC phones are not new to me entirely). I don't know what else to do. I tried a Bell SIM card and tried all of the same options to no avail.
I really hope someone can figure this out. I don't want to have destroyed a phone that I just bought for my wife. Her Atrix broke and I purchased that outright as well, so this is really killing my wallet. I've been through about 10 Android devices and I wouldn't say I'm a newb, but I really do feel like one right now. This sucks!

Get a new sim from tmo if it's over 2 phones old.

Exactly. Although I got it before I saw your post, you were completely correct.

definitely try a new sim card.

I've tried 5 different SIMs now. It's not a SIM issue. The other poster has a different issue but mine's identical to the OP's.

look for the only drop down box - hit it - choose wcdma prefered - hit back 3 times
Go to menu settings woreless and networks
hit mobile network - it need to be ticked
hit mobile networkS hit APN or Access point names - hit the menu button - choose reset to defaults
go back to mobile networks - choose network mode, select wcdma only - look for the 3G or h sign when it shows go back and choose gsm/wcdma auto
if that fails do a manual net work selection - choose your networks 3G option

I did try every setting in there. The new sim card fixed it! So I guess our problems are different.

WIFI is forcing network settings to GSM Only when on.

Whenever my phone is connected to wifi it switches the phones network setting into GSM only. It essentially drops all cell signal. It still works over the wifi obviously, but I'm curious as to why this is happening?
As soon as I disconnect from the wifi, it immediately swaps back to the wcdma/gsm auto.
I cannot attribute it to any apps, or my ROM specifically (ARHD 6.7.2) because it was happening before I wiped and flashed the phone.
I don't think this is normal. Does anyone else seem to be having this issue?

Same. I tried different Kernals and different Radios as well.

I tried different ril/radio sets. Didn't work
I have to try stock RUU.

Thats normal nothing to worry about keep in mind our devices is infact GSM

I solved the problem. I cleaned contact pads inside back cover with alcohol and cotton earbud. Cleaned also contact springs.
Problem is gone since over week now.
