[Q] Wont go past 2 bars

Hey guys. I dont know if this is a big issue or not because my phone doesnt drop calls or anything. After rooting and going to CM6 my bars for sinal don't seem to ever want to jump past 2. And if they do get past 2 its only for a split second then my bars drop again. I know theres a RADIO and a WIMAX to flash as Ive read but never knew if that was necessary or not. Anyone have any ideas?

I am on CM6 official and I have the same problem, I have reflashed multiple times as well. My internet speeds are horrible speedtest and xtremelabs reads me at about 500 kbps tops. In the past I was getting 1.5 mbps easy.

I believe the bars dont represent signal strength but 3 g signal strength. I've been using cm6 since the first nightly

I have heard this before but it does not explain my slower data speeds. I have been using Evo since launch I download constantly and browse the web on a daily basis. Since going to CM6 I have noticed a considerable decrease in speed.
-I flashed to the latest radio updates
-I went back to an earlier rom and made sure the pri is updated
-I've reflashed multiple times
Still no help and speedtest and xtremelabs speedtest has me rated at half of my usual internet speed.
Thanks again!

Can Sprint blackball your bandwidth?

I have no idea what is going on, but my 3G speeds have gone to ****. I've tried everything to get them back... I just don't get it...
This is with 2 'coverage' bars on CM6...

How long ago were you getting good speeds? Because it could just be the Sprint network, because they have gotten a lot of new people because of the new phones to come out, and that could be the cause.

I've had my phone since Aug 11th... So almost a month and a half... My speeds have just got worse and worse as time has gone on... Maybe the network is overloaded, I don't know... but man it sucks.

Try rebooting. I was having that same issue some weeks back. I was hitting > 14.4kbps on 3g and 3.2mbps on 4g. I did a quick restart and 3g shot back up to 600ish kbps.

sometimes this is the case, not just the evo, but having to reboot the wife's hero also.

I notice that at night my speeds drop dramatically. I can play youtube vids in the day time without any stutter but once it's about 8pm the numbers on speedtest drop and I have constant buffering. I don't know if it's because everyone is home and bandwith is being used a little heavier or if sprint automatically drops the bandwith at night.

I've tried rebooting multiple times with no luck... looks like I'm either being capped or in high usage area...

your ping is pretty terrible too - did you try other servers?

My 3G got really bad right before the unofficial launch of 4G here. Not quite as low as what you show, but BAD compared to what it was.

Welcome to Sprint, mine is exactly the same. I can rarely get over 500 kbps at night but can usually get 1 mbps or better during the day. The weird one is that at night my upload speed is almost always higher then my download speeds.
Night before last I noticed my browser was unusually sluggish so I did a speed test. Download was 39 kbps upload was 150 kbps, did a test the following morning and it was 1101 kbps down and 550 kbps up.
This is in a very rural area, so I seriously doubt if the tower I am connecting to is getting overwhelmed with bandwidth usage.

Haha, I can hope my man...

Wow, yeah that's pretty bad. I am getting 960Kbps (1040 max) down and 88Kbps (158 max) up speed on one bar (-89dBm)... ran Speedtest right now to check what I'm getting.
Stuff might very well be congested over there, although one way to for-sure rule out bandwidth capping is are you doing anything to cause them to cap your bandwidth?

I'm consistently hitting right around 400 kbs down and 800 kbs up, the only time I hit higher is when I'm roaming then it's 1 mb down.

Not that I can think of.. I use my phone a lot, but it's not like I'm browsing torrents or anything... Most of my bandwidth is probably youtube and ROM downloads...

I'm on CM6, the 9/19 nightly I think (or 9/20 I can't remember). I don't think it has any affect on 3G speeds. I flashed the latest radio and PRI if that makes a difference (didn't notice one).

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

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.

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....

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...

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.

Underwhelmed by the Sprint Samsung E4GT (SPH-D710)

The firmware on my wife's SPH-D710 was just upgraded to FH13. Based on my reading here, that upgrade included an improvement to the 3G modem. If that is true, this is a pretty sad phone - let me explain.
I downloaded Speedtest to my phone, a 2+ year old HTC EVO and here phone. I then ran Speedtest on both. (Actually, it was much harder than that. The GPS on her phone was simply not working, and Speedtest thought I was near Wichita, not southeast Michigan. Even after rebooting to get the GPS working, Speedtest still thought I was hundred of miles form here. Fortunately, the second-to-last server listed overlapped with the servers listed on my phone.)
To be clear: I did one phone then the next. I turned off the WiFi and help both phones in the same location.
HTC EVO: Ping - 192 ms, download - 2531 kbps, upload - 612 kbps
Samsung E4GT: Ping - 173 ms, download - 1789 kbps, upload - 520 kbps
The only difference is that my phone is rooted and I am running AdFree, but that certainly cannot account for the huge difference in performance.
I was actually quite pleased with my wife's phone until I a) ran headlong into the very poor GPS performance and b) saw the poor modem performance. I understand now why HTC phones cost more...

I thought it was common knowledge that the antennas on the e4gt were a little weaker than most, that seems to be a common trend in Sammy phones. If you want strong antennas I'd recommend Motorolla, however the software on their phones is ****. Motoblur, bleh. Regardless, Samsung still makes the best phones on the market and smother everything else out right now. The S2 helds its title until the S3 came out, nothing tops a Sammy phone but another Sammy I believe the smooth performance and top of the line GPU/CPU/screen is a good trade off.

My apologies if this sounded like a troll message. My wife's phone is clearly faster than mine with regard to processing speed. This is clearly noticeable when updating apps. My post was more a matter of disappointment - why it should clearly excel in some areas but seem to fall flat on others, especially given that it is a much newer device.
I just downloaded and installed Quadrant Standard on both phones. My perceptions were correct - the Samsung is MUCH faster than the EVO. So, again I ask/wonder, why the much slower 3G speed and poor GPS performance?

Your Samsung radio is not going to do better than the HTC radio, first and foremost you have to accept that. Then you can move on to trying out other modems in an attempt to improve signal and download/upload speeds.
There's a LONG list of them that have been released since back in February; you'll find the downloads for each in a stickied post in the development. It doesn't matter what kernel or ROM you are running, you can swap out modem builds at will. If one doesn't work, flash another but always make sure you update profile & PRL after each flash and before running any sort of speed tests.

Fh13 is battery improvements, if you update your prl that will help with download speeds. There are way to many variables for data speeds to get reliable info. 1.7 mbs download is damn good on 3g, I wish I got those speeds, I get .5 MBS if I'm lucky in Sacramento, ca. So anyway unless you have one of the lte phones that Sprint offers there is no better phone then the S2. And those phones are by no means leaps and bounds ahead of this one.

Thanks for the feedback. I am not an expert with regard to these matters and had assumed that a) the the newer phone would have a faster modem than the older one and b) the download speeds I recorded were not out of the ordinary. My expectations have been reset and I will enjoy her phone (when I can) for what it does well.

Those speed differences are small, I don't think you will notice. Also the faster processor will probably still load Web pages faster even with the slightly lower network speeds.

You'll find there is a whole lot to love about this phone and with the amazing developers in this forum your choices for customization are endless. Getting rid of my E4GT was one of the hardest things I've done (as far as my gadgets are concerned) but I'm also enjoying the SGSIII.

You have to understand something, network speeds tests are not exactly reliable measures. If you want comparable measurements, you have to run multiple tests on the 2 phones using the identical server at the same time. Then you average the tests. Otherwise, what you have is one data point, testing from a server at different times. So one point may have been when server was less loaded, or the network was less loaded. And even then, your original tests were close enough that you would not notice it, and to be "underwhelmed" just because of that is silly.
Root has absolutely nothing to do with data speeds. What accounted for the improvement is most likely a decreased load on the server or Sprint's network. I have seen much more variation than that on my own phone, simply by testing at different times of the day.

worrying about a 500 k difference on what appears to be pretty great 3g(remember, some sprint users get literally 100kbps) seems kinda bourgeois. how much faster do you need your porn to download?
