[Q] Signal Strenght Reports Wrong - Galaxy S II Q&A, Help & Troubleshooting

Hi there.
I got this problem which has been annoying me for quite a while, where the signal strenght given in dbm, is reported wrong. It can only show 4 values:
-89dBm
-95dBm
-101dBm
-107dBm
Even when i am close to a transmitter, it gives me -89dBm, where my previous GS would show -51dBm.
I assume this is only being shown as -89 but in fact i have better signal, but is there a way to fix this?
I found some posts on xda with others having the same problem but no solutions found yet.
ROM, Kernel & Modem changes have no effect, they all show me -89.
Thanks,
Ben

Whick firmware does the phone have now? Because i don't have this problem

I have ran Slim ICS, Hydrog3n ICS and now it is on Resurrection Remix.
All roms gave the same results, the current modem is NELP2, though i have tried like 7 which gave me the same result. Also, now i am running Siyah kernel, but i have ran Fluxi, CM standard kernels etc.
My neighbour's phone which is running WIUI seems to also have the same behaviour as mine.

I'm aware this thread is old as hell. But hey there's no answer to the question, I'm having the exact same problem. Even driving to the tower I still get exactly 89dBm when my other S2 goes around 60dBm

It will be down to your modem version which has been updated at some point by a rom. Go to the modems thread (use search) and try another.

[Q] Data Issue with Phonebreaker 2.1 Rom

Hi Guys,
I recently got the SG2 on AT&T (i777) and the first day I had it stock I was getting consistent H+ connection in my house and pretty much everywhere I was going. I ran the speedtest app a couple times, and I was averaging 2.5-4 mbps downloading which wasn't too bad.
That same night I rooted the phone and flashed Phonebreaker 2.1 rom following the correct steps (Not my first time rooting/flashing roms, I've done it to my Tmobile SG2 a few times). However the following day it seems my data connection has become inconsistent and speeds have slowed down to a drag. The indicator on the phone can never stay on H+ or even H..it consistently cycles from H+ to 3G to H (tried it in same locations as the first day with the phone). I ran the speedtest a few times and my download speeds ranged from 300Kbps to 1.6mbps if I was lucky.
I tried looking around in all the forums, I re-did the APN settings found in these forums, I troubleshooted with AT&T but to no avail.
Anyone have any suggestions? Would much appreciate it as I love this ROM minus this data issue I'm having.
FYI - Stock only shows H+ even if your not actually on it.
Its an illusion AT&T does to make the user think they have great connection everywhere.
Also try flashing a different modem, that might be the issue with your speeds, cause I changed to the leak's modem upon many request.
Thanks LiLChris06!
I tried the KH7 modem which did nothing, and I tried the KK6 which seemed to improve it a bit. I went into AT&T today and they said maybe it's just a defective phone and were willing to switch it out, which I might do.
However I love this ROM so much, is it available without the custom modem you added or with a different modem in the install rather then the UCLK2 I think you included?
Thanks

Hmmmm...what you mean by is it available without the custom modem? Maybe Im reading it wrong. As you know, because you said you have tried different modems, there are many different modems you can try. Shouldn't matter what modem the ROM comes with. Think there is a modem thread around here that has some good info. I think Task also just uploaded the the new LC5 Modem
I should have worded my reply a little better, and it might come across as a newbie question but basically I was wondering if that rom came with the stock modem the i777 comes with because when I had the phone the first day stock, the data speeds were pretty reasonable (3-4 mbps/downloading).
Wasn't sure if flashing different modems other then the one that came with the phone originally would help out my issue, but I suppose it doesn't hurt to try. I did find the UCLC5 modem so I'll try that in a few minutes along with the other ones I haven't tried. If no luck, I'm going back to AT&T to exchange, probably defective phone like they said.
Thanks again for everyone's help
Sweet, found a solution!
I tried all 7 different modems under the same conditions, KJ1, KJ4 and KK6 were around the same ball park. KH7 and UCLC5 were a bit slower but close to each other, UCLC2 was by far the worst..and the winner was KJ2, big difference.
Thanks guys!

Radio Needed For Cyanogen And Samsung Galaxy S2?

Hello, I've flashed the Cyanogen mod for my Samsung Galaxy S2? I've been using it, it works fine.
I'm wondering, do I need to flash a radio? If so, which one? I've seen the links of radios from the Wiki page of Cyanogen under Support Downloads, just don't known which one to use or if I'm supposed to.
Thanks for your help.
Radio is not changed by CyanogenMod.
If you have no call, sms or data issues then i dont think you need to change

OK, thanks for your help.
I have successfully installed this rom. I think it's the most amazing jelly bean rom for galaxy s2 at the moment. I like its smoothing and quick response. feel a bit warm at the back and the battery is losing 1% at every minute while wifi is on. Over all is great. Cheers!
Actually, I've been experiencing data connection problems. My phone works, but it won't connect to 2g/3g for internet.
Should I try switching radios?
If so, which one is recommended? Or do you just try them at random?
Thanks again
On first boot normally can't get mobile data to work because APN was not configured properly (or the list empty), after a reboot mobile data will work again. If it doesn't, then you have to key in the APN manually.
For radio/modem, since there are no changelog released and nobody know what are the differences among them, it is assumed that the latest one will be better.

first and foremost asking or recomending which ROM/KERNEL/MODEM ,is against XDA rules, since all phones are different due to various reasons , hence if u have a an issue with ur modem u have to try a cpl of them on ur own and see the one suits u the best.
link for the same below.

OK. I'll try a few different radios. I see a list of links in the Cyanogen Wiki page of under Support Downloads.
Thanks for the quick replies!

It sounds like your apn settings are messed up. Try to reboot twice and then try. If that doesn't work, you will have to find the settings and input them manually.

After trying over 30 radios I always end up on nelp3. Best signal best data thoroughput and best for battery life.

Thanks everyone! The radio did it!
I flashed this radio:
galaxys2.radio-XXKDH-signed
Now, the data, 3G, works great.
I've been experiencing an issue and have read several post about RADIOS on the SGS2.
I flashed my mobile with the nightly 10.2 CM and after that it started to ask me for "SIM network UNLOCK" Which I can't unlocked, thought it was the version issue so I dl a the newest one and same issue, I tried the ICS stable 9.1 and same issue.
I've read something like radios on the CM support part. Which I dunno where is it yet . If I need to flash it and u guys can help me out to pick up the correct one I'll appreciate it. my model of SGS2 is the i777 from AT&T.
May I install NELP on my CM 9.1? how? where can I get the files to do it?

What phone do you have? This is the thread for the i777 S2 variant, and at least one of the modems you mentioned are for the i9100 variant (don't recognize the others you list).
You can only use modems designed for your device, so if you have an i777 see the link directly above your post.

Strange signal problem

On my i9100 I have a really strange signal problem my suspicion is a hardware issue.
Let's start with the actual problem, from the title you can tell its signal related, it constantly is really low but in some places full. In places where other people on android get full signal I get no signal what so ever. I have tried a custom ROM (super nexus JB 4.1.2), I've also tried a few modems giving each a few days to test but they all act the same so I don't really know what to do in software terms. Any ideas anyone?

If you already tried different modems (and RILs?!) it could be a carrier or hardware issue.

Yeah I used getRIL for the RILs and as I say there's no difference, also I've tried sims from different networks in my phone and doesn't make a difference but they work perfectly in other phones so it mist be a hardware issue

[Q] Modem/Connectivity issue

Hello people,
For the past few months I'm having this issue which I find extremely [email protected]!!
Every few minutes, my phones just loses internet connectivity - the 3g signal appears to be normal during all the time, thing is, whenever I try to use any internet application - it just hangs. and then, after a minute or so, connectivity is back(again, for a few minutes).
I have tried flashing so many versions of modems - some improved it a little but most of them didn't help at all, or even made it worse.
Hopefully someone could help me with that as I'm that close to give up on this and buy a new phone.
Thanks in advanced.
Nir.
Which firmware are you running on your phone? What modem do you have right now and where do you live? Do you have problems with all apps that use internet-connection? Do the problems dissapear when you use wifi?
Just some information would be usefull

Yop.. forgot to mention a 'few' things...
Model: GT-I9100
Rom: RootBox V3.8
Kernel: 3.0.31-CM-g7ce58e6
Baseband: I9100DXLPB
Android version: 4.2.2
I live in Israel, bought the phone in Thailand.
I tried flashing all available Israeli modems(from various cell phone providers) - none helped.
Problem disappear when I move to WiFi - as 3g connectivity moves to background...
Thanks.
I assume you've read the Rootbox threads to see if other people experience signalproblems?
Did you compare the connectivity with other roms? Stock-based roms for example...

That seems quite weird.. The only thing I can come up with is 1) a hardware problem, or 2) you live in an area where the signal is crap
Hopefully someone else knows anything.. Good luck.

Anyone else...?
If you've only tried flashing the modems bundled with stock roms from Israeli carriers, you haven't done nearly enough. There are literally dozens of modems available, you need to start flashing as many as you need to. This isn't going to fix itself magically.

I haven't flashed only Israeli modems but others as well. I've tried around 20 so far...
Question is, which direction should I choose? should I look for Thai modems or IL?
That depends. I know Israeli carriers sold (still sell ?) the I9100T, are you sure you don't have one of these ? If that's the case, I'd be trying modems bundled with roms released by the Australian & NZ carriers which sold the I9100T (I have one), and yes, the Thai ones as well.
If you do have an I9100, then keep trying any/every modem you can get your hands on. If it's not a carrier-side issue, this is really all you can try, unless you want to start messing around with RIL's as well. I've not found any difference in connectivity doing this personally (tho many people have) but if you get to the point of trying every single modem & you're sure it isn't a carrier issue, you might as well try. But I would leave this till last given many people find their connectivity messed up even worse by flashing an incompatible RIL.

[Q] Can I change modem im my AT&T Note?

HI everyone... I have a question:
I have an at&t sgh i717 with a virgin sim (Im outside of the us), and I need to choose a new modem (I think) because currently I have this t989 uvle1 for tmobile that I had to use to unlock my phone. I'm getting three bars in the signal so my question is or are: do I really need to change the modem? Does the signal have to show more bars so that one can be sure that the modem fits the phone? And, a modem has to be chosen depending on your phone and on your location (since I'm in southamerica)? does having a 2.6.3 kernel affect any of this, should I upgrade it?
I hope I'm not asking too much, sorry,
thanks
Wrong forum, belongs here. I've asked mods to move your post, sit tight.
Edit - You mean i777, right ? (I717 is the AT&T Note).

Since you have an i717, normally you would probably want to flash back to an AT&T based modem. However, since you're probably not on AT&T's network, your best bet is to try several modems and see which one works best with the provider in your area. My recommendation is to at least base your tests on signal strength and speed tests.

OK, I'm going to try several because just yesterday I found out that my gps didn't work and I think that's related to not having a suitable modem.
Additionally, I performed a speed test and whereas I get 12 mbps for download in my laptop I got 10 mbps in my phone, not much of a deal though.
Regarding signal, I get from three to four bars which isn't that bad and I've made a couple of calls and everything seems to be fine.
Since the gps thing is a real setback I'll flash another modem but I'm also thinking on upgrading to ics because right know I'm on gingerbread 2.3.6 with 2.6.3 kernel so I wanted to know if It's better to flash the modem before or after upgrading.
Thank you for your answers
You will probably have better luck if you upgrade to an ICS or jelly bean based rom.

The gps not working isn't always antenna issues. You can try to update the gps data file. Go to the market and get a gps fix app. You're looking for an app that will replace your gps configuration file with an updated file.

Thanks, good to know that.. it's just that when I received the phone it was working and based on that and some comments on internet I attributed this error to the switch in modem/baseband/radio...
Anyways, I'm installing a rooted ics rom and I'll come back to comment, hopefully positive things
