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).
Anyone else having this issue? My 4G speeds are cut in half with any of the ICS roms. I get on average with Tuesday or Eugene's CM7 rom 14 mbps down 3 up and with any of the ICS roms, the down is cut to 6 mbps down. Is there any known reason for this?
I have not experienced this...try flashing the blaze modem?
I've noticed that using the latest Racing ICS Hercules ROM that the 4G signal does appear to fluctuate quite a bit and at one point died completely. I had to turn data on and off for it to come back. I have flashes the latest kernel if that makes a difference.
I've also done Speed tests and I rarely go to 4 Mbps. Before on Gingerbread I would be upward of 7 Mbps.

I have not noticed this at all. In my area I get equal speed, around 12-14 down and 1.5 up. I have never had more than 2Mbps up.

Yes I've tried this but even with the blaze modem for ICS, I get half the speeds I get on the Gingerbread roms. I'm surprised no one else is experiencing this.
i have experience the same to it only improve with a script called 3g turbo charger in fastest mode 4
Highest I get on 2.3.6 is about 6-7mbps in my area, same on 4.0.3, gonna do a test in other areas to confirm this though.
i average 8-11Mbps down on both gb and ics.
Half speeds would be great. I get about 10kbs with any ics rom and the LB7 Blaze for ICS radio.
I get half of what i get with GB too, i usually get 12-20 with GB and now i get 5-8 and sometimes 12 by accident?
I barely get a signal on any of the ICS Roms to the point where talk\text and data no longer work

That's about what I am pulling
I have run pretty much all the ics roms and speed hasnt been a factor at all ...been getting 17 to 19 mbps..call echos is whats killing the ics roms
I've been averaging around 7-15mbps down, 1-2 up on ICS Perfection II and was averaging 5-12mbps down, 1-2 up on Racer's Skyrocket ICS port.
With stock GB, I was getting 17-22 in most areas of Glendale, CA.
It's gone down a bit, but nothing I'd notice in day to day use. The signal strength has stayed the same otherwise.
On a regular GB rom I'd be hitting 6- 15.. with ICS I'd be lucky to hit 4.
EDIT:: Does anyone know if flashing another modem (in my case the original Telus modem) would help?? or brick the device? lol
Hi,
I've been using JB since the version from io12 was out. Currently I use Bigxie's deodexed 4.1.1 and all is wonderful. Except one thing that is. The wifi signal is weaker than I'm used to from ICS. Especially the wifi range seems worse. Connections that I've used with ICS are now out of range. Some of my friend or family's connections are now very weak and I drop out of range very often. This goes for any JB rom/kernel I've tried.
I've tried several roms, trinity and franco kernels, dirty flashing, full wipe. I've even tried a couple of different basebands, even though I don't think they affect wifi.
So I'm wondering if other GSM GNex users are experiencing the same thing? I've seen a thread with a flashable "poor wifi fix" for the Verizon GNex, but nothing for the GSM version.
Verizon GNex wifi/gps fix:
http://forum.xda-developers.com/showthread.php?t=1739097
Any suggestions? Coukd a similar solution like the Verizon fix help?
Best regards,
P
Ok, allow me to explain whats going on with the "fix".
There were some folks who ported the GSM version to Verizon (myself included). However, they failed to use the correct wifi/BT firmware (I did but thats besides the point). They left in the GSM version. So that above fix is merely the bcm4330.hcd firmware and bcmhd.cal calibration file for wifi/BT from 4.0.4 for Verizon. It is not meant to be used for GSM and only applies to those who ported GSM to CDMA. Even with the fix, wifi is weak.
Verizon users currently have a newer version now, specifically for them from Google. However, the weak wifi issue still exists even for us. There are some who have strong wifi routers or are always close to them that do not see the issue, but it does exist for every JB user. Wifi is simply weaker, and BT is fairly janky.
It is a Jellybean specific problem, and I am assuming it will be fixed in time. You could try a 4.0.4 bcm4330.hcd, bcmhd.cal on Jellybean, but I doubt it will help, and it could end up hurting. I am thinking that broadcomm needs to fix these files.
Thanks for the reply and the precise info about the problem and the background for the Verizon fix. Very much appreciated.
I guess I'll have to wait and hope for an update.

The more I think about it, the more I think it can probably be resolved by tweaking the calibration file. However that is a bit beyond my abilities as I don't understand whats contained in it to know what it needs tweaking to.
wifi weakness
I'm not sure why it does this but when I am in my house about 15 feet away from my router I would notice my wifi signal dropping down to 2 bars where my other phone would stay at full strength until I got around 15 yards away.. I decided to see how far I could get away from my router before completely losing signal. I walked a total of about of 30 yards from my router to the edge of my street and stopped every time the signal decreased down to one bar(which was between every 5 or 10 yards)... every time I thought the signal was about to drop out it would return back up to 3 bars after a moment of adjusting. Once I got to my furthest point it dropped out completely and then came back to 1 bar. When I came back inside where I previously had 2 bars I then had full signal throughout the house. I tested this a couple times and it seems that it only uses what it needs. If someone could do a similar experiment to confirm this isn't specific to my router set up I would appreciate it. I also did not notice any drop off in performance in speed from 1 bar to full signal while I was within 20 yards of my router, however, I didn't run a speed test, I just used my youtube app to load a video... I will run some speed test when I get home this evening to get a solid figure on the speed difference. This may not be a bug but a feature to conserve energy to increase battery life.

A good theory, but I am dropping wifi in some of my rooms. Switching to and fro like that doesn't save power
didnt people have poor performance with their wifi signal on ics? did broadcom leave everything the same of did they change/update drivers for our phones with jb.

Me too, I only need to move to the next room or so sometimes. The main problem for me is range. The range for me was better with 4.0.x.

ICS wifi performance on the GNex wasn't exactly perfect for me, but it was better than what I get with JB. My router at home is giving me an okay performance and range, but the routers I normally connect to at family and friends are giving me problems since I moved on to JB.
I believe JB does come with new drivers. At least I've read that it does, in other threads.

Wi-Fi has been fine for me, but only when using 2.4GHz—5GHz, on the other hand, is horribly broken. If you are using 5GHz, I recommend trying 2.4GHz instead—hopefully Google will have this sorted before the Galaxy Nexus II ships.
you may want to revert back to ICS to verify if the phone hardware is not a problem? otherwise for me I have used both... ICS and JB, and I don't find any difference..

5 Ghz was fine for me on ICS. It works on JB too, but the range...ugh.
I'm pretty sure it's not hardware related. It's definitely related to JB. It's not a 5 GHz problem either, that's what I use at home on my d-link. Family and friends have both 5 and 2.4 GHz. I'm sure it depends on the quality of the routers also but I didn't have any real range problems with any of them before JB.

2.4 is pretty weak for me too.
I looked at the calibration file from ICS to JB. I don't think the difference warrants the problems seen.
From ICS to JB, these are the changes:

rxgaintbl100=1
# 5GHz Starting Tx Gain Index
initxidx5g=96

Silly question but it must be asked. Are you sure that your friend's S2 is with T-Mobile and not Sprint or some other carrier?
Also, are you using some funky aftermarket case that might be blocking your reception?
Third, here's a link to the newest radio. I've tried all and it is by far the best. I get d/l of 27mbit and upload around 3.6mbit. Insane speeds using a touchwiz rom.

If you were on CM then it's a known issue but you said stock rom so.... I'm fresh out of ideas. There's no reason why yours should be slower. My speeds are insane and there really isn't much different in your setup. I suppose maybe your antenna isn't connecting like it should? Do you have weak or low signal that is lower than your friend's S2? If they are the same then it's not an issue.
If you are rooted the first thing to try would be to flash each of the radios in the dev section. Could solve your problem right there.
If that doesnt check your build.prop and try a few of these values:
ro.ril.gprsclass=12; 30;31;32;33;34
ro.ril.hsxpa=3
ro.ril.hsdpa=26;28;30;32;34;36
ro.ril.hsupa=7;8;9
You will only use one number at a time for each. I listed multiple as any one of them can be best for you in your location.
My recommended starting values for testing are as follows:
ro.ril.gprsclass=32 then 12, 30, 34
ro.ril.hsxpa=3
ro.ril.hsdpa=28 then 32, 34, 30
ro.ril.hsupa=9 then 7, 8
Good info about these are on Wikipedia.
You will need to reboot after each change for it to take effect. Time and data consuming to test, but it might help you out.
Thats just my recommended testing method. You can of course jump around as much as you wish!
Make sure there is a blank line at the end of the build.prop and also check for and delete duplicate entries.
If all else fails go to tmobile before selling it. Ive heard of a number of people getting replacements for stuff like this, even after the remorse period. If you can get an S3 going good itll blow that S2 away! I see no reason why the S2 should be significantly better in any area!
Good luck!

Hi guys!
I am having a BIG issue with this ROM with LTE connection.
I thought at first it was a matter of issues where I live or maybe I was being capped by ATT (I should not be over the limit yet) but yesterday I decided to test at home which usually is about 20Mb download and got the same result as I get at work, not even 1Mb down! Really just about .55 and 1.18 upload!
I checked the APN and it looks like the normal ATT settings I use but even tried some other "alternative" ones I have used before and same thing. Changed the modem to the one on the OP and same issue.
Tested a different ROM and back I was at the 20Mb download at home.
No idea what is going on but this is a killer for m :/
Anyone else seeing this?
It almost looks like it was been capped since it speeds up to 1.5 and then starts kicking down to that .55 or so level. But as my test showed, it works fine with other Roms
I am more surprised not seeing more reports about this. This is testing right after flashing so no other apps could be causing this etc.
Unfortunately i was getting all-around sluggish performance from Skynote 4.3 and was essentially forced away from it to get better performance out of my device. On my t0ltecan(TELUS) i was getting about 1/2 speeds compared to my typical on other ROMs
Well now I am totally confused. Flashed CM11 again today and my speed is still slow. So it looks like throttling but that does not explain how I got normal speeds yesterday...gosh I hate mysteries like this! :/
