Weak !! 4G signal/service on custom roms ,not on stock.

I've bin pretty disapointed with the roms signal and service strength on my G2 lately.
When I bought my fone I had full 4G bars all the time in my area and at home, so it can't be that "towers" moved or network error. I can explain why.
First with stock rom I got it all bars, rooted and everything.
I notice the signal change once I jump to a rom first was virtuous, I get 3G all the time..speed test sucks and it sometimes goes to edge. It goes to 4G once in a blue moon...for only like 6 seconds max. I swear.
Than I go back to stock "backup" and my signal strength is back to awesomeness and check speedtestt and they're out of hand perfect.
So I stayed stock for a bit, tried other roms and same crap.
Stayed stock for a bit more longer, now on cm 6.1.1 and its not as bad as it was but its really bad still. Edge is on as I speak at a spot where 4G is full strength all the time at my house.
I need help figuring out what's the cause? Is it a kernel? Or something? If so can I flash the stock one for it on the cm so I can have my stock speed since its the best?
Or what can it be?
Pleeeaaasee help ! I wanna enjoy this rom,but without excellent signal/service strength it means nothing at all to me but back to boring old stock...
Thanks..

did u check ur apn?

Not really, but it shouldn't have bin touched since the apn isn't in stock.
Just don't get why all of the custom roms have bad service but when I got back to stock with root and all the service goes back to being excellent again.

Compare 6.1.1 and stocks build.prop files
Maybe you will find your answer there?

Another point to make is that the stock rom doesn't show a 3G icon.....it just displays the 'H' icon regardless of whether you are on 3G or 4G.
So when using the stock ROM, you just *thought* you were getting 4G all the time when you were actually only getting 3G connections.
On the non-stock ROM's, they actually differentiate between 3G and 4G. Thus you get to see when you are 'really' using 4G and the few times you actually get 4G speeds.
It's all a marketing game by the providers.

Your right, the stock rom doesn't differentiate between umts n hspa. But one thing I noticed is that all rooted roms have a slight lag when switching from umts n hspa.

I can totally attest to this statement. Stock data access speeds and signal is much better than custom ROMS. It must be something that is missing in the kernel or maybe the ROM itself. Dont think it is the radio because no one has mentioned flashing another radio in any of the stock roms list so far.
I am on CM 6.1.1 right now and I really want this ROM to have the same signal as the stock....

I have the same thing on mine. When I tried cyananogen my signal was crap. I would get slower speeds and less service overall. Same for MIUI. Couldn't handle it and went back to stock. Not to be unapreciative to rom developers but its hard to beat stock connection and battery life

I agree, I'm currently back to stock till someone finds out what's the problem and fixes it.
This clearly states its not only me.

Wish you where right, but I wouldn't post this up if it was just that.
I tested the speeds out with speed test and my results cleary show that stock has perfect 4G speeds. also used tethering and on my ps3 it loses connectiong with custom roms. When usually it doesn't . So, it couldn't be that. Download speeds and everything lags a lot, and I go to edge awhole lot where I'm at when I'm always in 4G.

I have owned many diff types of android phones. And all were rooted with custom roms and all exhibited the "laggy umts to hspa switch."
might be something we r gonna have to comprimise...
On an unrelated note. My n900 from nokia is capable of hspa plus but only till about 10mb where as my g2 can pull in about 14mb. Today I noticed that the n900 consistently hovers around 5-7mb per second where as my g2 hovers around 2mb-4mb per sec lol.
Can't wait for the nokia n9.

I'm confident your answer is in /system/build.prop. Check the HSDPA and HSUPA categories.

And what do I do here?
Is it possible, that everyone that owns a G2 having this problem but doesn't notice it?
We need to let people know.

It's gotta be something in the software, a setting gone awry or accidentally unnoticed, a line in the kernal code or something.
Eventually CM or someone will figure it out and we'll enjoy "4g" speeds even while ROM'd up.

I believe its in the build.prop file. Rodriguezstyle once released a beautiful black n green rom for the nexus one. It didn't exhibit the umts to hspa lag. I remember reviewing his build.prop. it was definately very different from what I have seen in the past

Is it possible to port his build.prop into one of our existing ROMs? Maybe that'll fix the problem.

Ive compared the build.prop files from a stock backup and 6.1.1 and there's nothing in there in the communication settings that would be causing this. They're literally the same going down the list.
It must be the new radio 6.1.1 uses which isn't the Tmobile stock radio. That's the only thing that could be affecting communications (bars and data speeds).
But I agree I'm seeing similar results i an HSPA+ area where Speedtest seems to get stuck and wobble around 1.5mb down like its some kind of cap or something. Haven't seen a huge signal bar drop though.

Yes stock ROM to CM 6.1.1 was what I meant. Nothing different in build.prop that would affect the radio portion. Just some memory tweaks but that would have nothing to do with the signal or data speeds.

Oh ok. Sorry for the confusion.
After the new g2 update I actually got stronger signals n better data speeds though. I don't think downgrading the radio will help....
But its worth a go I guess

[Q] Problem with connectivity speed

I apologise if this has come up before. However, and I don't understand why, my HTC DEsire was running perfectly about 2 weeks ago. But for some reason after I installed the iNSertCoin ROM my internet speed and market download speed is INSANELY slow. My phone says that I've got a 4 bar HSDPA connection so this really shouldn't be occuring. I've reverted back to the GingerVillain ROM (the rom I used before iNsertCoin) and it's still a problem.
I've tried many different Radios with the correct RIL's and nothing seems to work. It works fine with wifi (don't know why that would help but meh )
Help would be much appreciated guys. THanks.

Is anybody there?!

Come on guys. Someone help lol

You do realise that using something like HSDPA or 3G connects maybe miles away. It also depends on how much connection your carrier is giving out. Just use Wi-Fi or something but using something like HSDPA isn't always guaranteed to be 100% fast at ALL times.

Check at your carrier if you have any kind of maximum bandwith use. Maybe after like 200MB data transfer your account gets limited speeds. Fair use policy or something. Maybe that's why your speeds are so slow.

My plan is Unlimited Internet and I'm 100% sure I don't use so much that I exceed the fair-use policy. And my point is that 2 weeks ago it was perfectly fine. The speed was fine and I haven't moved house or anything. Just seems very odd that it would drop so much. For example, it takes me A VERY LONG time to download an app now. Before, this wasn't the case.

Slow 3g speeds

Lately I have been experiencing some slow 3g speeds. At first I thought that 3g reception in my area was just not very fast, however I don't think that's the case anymore. For example, I did a speedtest and got 300kbps down and 400kbps up while a friend of mine standing right beside me (also on verizon and has a Droid X) got 1000kbps down and 500kbps up.
What could be causing slower 3g speeds? Any help would be great as slow speeds are very annoying. Also now he keeps insisting that his phone is vastly superior to the Dinc...

Not sure what would be causing that. Have you tried flashing different radios?
Also, throw our massive dev community in his face if he thinks his phone is all that. Locked bootloader < Inc.

I have not tried flashing a new radio ever sense I first flashed 2.15.00.07.28. Is there another radio I should use or could reflashing that one help at all?

Noooo no no no no don't flash the radio again. That causes bricks, so I've heard. There are three newer radios than yours (9.01, 11.19, and 4.09, in that order), but there isn't any way to tell which one will work for your phone in your area except by trying them yourselves. But... Flashing radios is risky. You should always check your MD5 sum with the one provided from where you downloaded it. You can get them all from www.dougpiston.com

Only way to brick is to pull the battery when flashing the radio. Check md5, have a good charge and you'll be fine.

Ok if a new radio might help I guess ill try that.
The same friend mentioned that his rom included something that removed the data throttle. Obviously that could increase speeds... anything like that for the Dinc?

I don't know if it was just the natural variation in data speed but I got better speedtest results with the 4.08 radio. As far as throttling, if there is any throttling done its on Verizon's side and you can't do anything to your phone for it. If you were being throttled you would see an icon in your status bar and (should) receive notice from Verizon. The only people that would be throttled are (I think) the top 5% of data users so unless you use A LOT of data I wouldn't worry about it.

Data download speeds really differ stock vs. CM7?

I was running speedtest.net app on both mine and my fiancée's DInc and noticed how much better my d/l speeds are while in wifi mode. I was at 10,000kb and she was only getting around 3,500.
Does anyone know why this would be? Why would the stock ROM not allow me to download at the top speed possible? Is it a CM7 thing or this just a fluke? Anyway I just found it interesting
Sent from my ADR6300 using XDA App

I run CM7 and have noticed slow speeds the last few months, but have chalked it up to network traffic. I am not a big data user, and when I run speedtest in the morning speeds are much more reasonable. I also ran a different speed test website, and it was considerably different. I don't know if the app is that accurate.

Through the different Sense ROM's and CM7 versions I've used I can say I get the same results.
CM7 has faster 3G transfer rates and WiFi. Don't know why

Cyanogenmod 10 Stable AT&T Galaxy S3 Connection

Hello, I I'm using the stable version that was just released and my phone keeps switching from H, H+, to 3G every 20 seconds or so?! What am I missing here? I have flashed all of the AT&T modems and the problem still exists and drains my better! I cleared everything before installing and everything else is working fine! Just not the data connection. Please help!

Sounds like a problem with AT&T. Some quick things to try when your connection is wonky like that is to toggle airplane mode on and off. I'm in Canada, so I'm not entirely familiar with AT&T, but I have read on a few other posts that they are a little sketchy right now as they roll out LTE to more areas. Also try running with just 3g for a bit, then try LTE and see if anything changes.

Tried doing that Still having issues.
I don't have LTE in my area, so that's not the issue. I do have the HSPDA+, so I get why I see the H+.
It seems to only be with the Cyanogenmod 10 Stable ROM that was just released 2 days ago. Doesn't seem very stable to me
I even just tried installing the nightly update that came out last night to see if there was a fix, and nothing.

Hmm, okay, well, then if it was me in your shoes, what I would try would be flashing back to stock with Odin and start over from scratch again. I find that's easier than messing around with radios and modems and everything. You can find a good stock image in the android development thread that already has root injected into it. Obviously make sure you grab the right image, yadda yadda, yadda.

If you're saying that its switching between 3G, H, and H+ in succession then its doing exactly what it should be doing. Think about it. If your devices data was constantly stuck on the highest speed (the most battery draining one) your phones battery life would be horrible. What aosp based ROMs do is show the true value of your data connection. What's happening is your device is switching to the lower level data (3G) when you're not using data services and then ramping up to the higher level (H+) when you're using data services. Touchwhiz based ROMs don't do this. They lie and always show the highest level data as always being used when in fact the data levels are actually switching back and forth like you're seeing right now.

Thanks, dude. I looked at it as a problem that needed fixing - but I guess if that's what it's supposed to be doing then it's not a problem at all. For some reason, I never see my data type drop from 4G.

If you're in an area with a really strong 4g signal it will stay on 4g. I've noticed that at work it stays on 4g the whole time but at home where my 4g isn't as strong it will switch back and forth.

Are you ABSOLUTELY certain about this? I will just let my phone sit there (not doing anything) and the icons go 3G, H, H+, back down to H in literally 3 seconds.
This doesn't seem right. Especially with my battery draining about 20% in a matter of 20 minutes. I figured it was because the data connection was jumping all around.
Can everyone else confirm that their phone is doing this too (jumping between all sorts of connections) that is running Cyanogenmod 10 Stable?
Oh, and I'm in a really strong "4G" area downtown Minneapolis, etc.

not sure why you would think that i would give information like this without knowing. either way. thats how its supposed to be. its flipping back and forth like that when you're not doing anything because of email syncing and things like that in the background. whether you think youre in a "strong 4g" area or not. your device knows better than you. if its switching in an area the you think its strong in, it's probably not as strong as you think if your device is saying otherwise.

Alright, thanks for the explanation. I might try it one more time tonight, but on the way to work today the data connection was flipping back and forth constantly, draining my battery as well too. I've been around the Twin Cities today (not just sitting in just 1 spot) and still happens. So I doubt the entire cities is not as strong 4G as I think :fingers-crossed:
Keep you posted.

WIFI Issues
Hi All:
I'm not sure if this the same issue as whats listed here but on CM10.0.0 Stable, wifi seems to fail to reconnect after the phone goes into sleep mode. In stock ROM, I could bring up the wifi menu by dialing *#0011# however on CM10 it doesnt work.
I know others have listed this issue on the web (not just xda) but wondering if any one has a fix? Thanks.

Okay, I'll admit when I'm wrong. Had some patience tonight and my mind wasn't playing tricks on me now that I got an explanation. Battery life is fine, and Internet connection doesn't go out when I'm on the browser ^_^
Thanks for your explanation!

hey...i know this might be a bit late but I'm on a rogers sg3 running CM10 stable as well and i mine is doing the same thing. I can understand where you are coming from because it seems that mine started doing this after i lost IMEI and restored. i think it's purely a case of me noticing things a little bit more after that whole ordeal. can't really confirm if it was doing this before but it seems to be working fine right now. recently i was in a very strong 4G(LTE) area and phone didn't switch at all...just stayed on LTE constant. At home on the other hand(rural ontario) my phone jumps around like crazy. I've even seen it go right down to E lol! So I, like yourself was a little skeptical and decided to switch back to stock and sure enought it just stayed right on H+ makiing me think that i was getting "better" service on a stock rom lol. but when i went into phone settings/about phone/status the mobile network type kept swiching even though it showed H+.
anyway...just my 2 cents. hope this puts your mind at ease
