[Q] GSM Galaxy Nexus 300kbps

My 3g was working very slow so i downloaded this app called sppedtest.net and my download speed is around 290-350 kbps and the upload speed test gives an error it can't even complete, what is wrong with my phone, i have unlocked it officially

would flashing a new radio help?

Are you in a bad 3g area with your provider?

What carrier? If on AT&T, you need to have it 4g provisioned

i am gsm, from romania, orange. in my house, this is not the problem because my samsung galaxy s 2 i had before was blazing fast..

here is a screenshot

please help?

I'm using a CDMA Verizon Nexus and my Speed Test app won't even work half the time. When it does my 3G speeds never go higher than what you show. Have yet to have uploads past 100kbps. I'm on my second Nexus already.

It's probably the tower and/or the server you're testing on, not the phone.
My GN blazes:

I went from xxkk1 to xxkk6 radio and i get better dl speeds now.

funny thing is that i have the xxkk6 now, so this is a software bug?

????????????

can someone answear pls

please can no one help?i can't do nothing without wifi and i am paying for unlimited data plan for nothing

a lot of us are from the US here so we won't be able to do much to help you since your an orange subscriber. if you notice, most of us have usa companies in our sidebar.
as far as your issue. i don't think it's something with the phone. your best bet is to go into the orange store where you bought the device and talk to them about the issue and see whats going on.
i'm on T-Mobile USA, and i've had no issues with the speedtest app and have been getting on average 5Mbps down on 3G.

I have the same issue with my Galaxy Nexus. It is bought from Spain. I have tried all GSM radios, several ROMs, including the stock ones, nothing. The same SIM, in a Galaxy S II, on SpeedTest.net app (same server) gets 5 mbps, on my Nexus it never goes past 300kbps and it extremely jittery.
I suspect the phone is defective. What are your thoughts?

Your best bet is to call up your service provider and have them run through the settings of your access point names with you to make sure the settings are right.
If it's a hardware problem, you will most likely not be able to connect to 3G at all.

That gave me an idea and I found the problem. On each reboot Orange forces down my throat the settings and it defaults to WAP. THAT is why nothing works on mobile data; if I delete all APNs and manually create just the one for data it is fine.

Very high latency with Galaxy Nexus on T-Mobile

I just got a Galaxy Nexus yesterday. Am upgrading from my Vibrant.
In Speedtest, my Galaxy Nexus gets an average of 1,600 ms latency. I've repeated the test with different servers over the last two days. I've never seen a test lower than 500ms.
If I take the SIM card out and put it back in my Vibrant. And repeat the same tests, I get 70-80ms typically.
Looking around, I don't think 1,600ms is normal. Is this phone defective? Something else going on? Download and upload speeds aren't impressing me either. Get about 3 to 5Mbps down and 0.5Mbps up. My Vibrant is 2 to 3MBps down and 1Mbps up.

that's definitely not right. Have you messed with the APNs at all or did you just put the SIM in and go?

I just put the SIM in. Didn't mess with the APNs.

Hm dunno. I just put my prepaid t-mobile SIM in my GNex and it works just fine. Speeds are great.

I have a prepaid SIM card on the way. Was going to switch from my contract to the Monthly4G plan. So I'll see if the other SIM works better before I freak out (freaking out a little already though, haha).

My 3G and H indicators are going back and forth quite a bit. Could this cause the high latency when switching from one to the other during the test?
If so, is it possible to disable HSPA+ since it's so spotty in my area? Might have to reconsider T-Mobile if HSPA+ is going to give me trouble.

What apn are you using?

The issue is 3G to HSPA switch that causes speedtest to halt and give you close to 2sec latency.
To solve this, start the speedtest as soon as it gives you "begin test" button, and repeat the test as soon as the test is finished.
If you give it more than 3-4sec after the test is done, your phone switches back to 3G and when test starts it takes about 2 sec for phone to switches back to HSPA and starts the test.
It's common.

I have the exact same problem. I have a Vibrant, and get around 120 ms, but my Galaxy Nexus gets 1500 ms. Does this even if I do back-to-back speedtests.
VoIP using GrooVeIP is next to impossible over HSPA+

How do I improve data speeds on T-mobile?

My galaxy nexus usually does 2.5 mb down and 1 up. It also usually says 3g, and when I start using the phone 4g "kicks in." I am using it on t-mobile right now. Is there anyway to get faster speeds?
I used to have a t-mobile galaxy s2 and would get anywhere from 6-10 down in the same area and 1 up.
Thanks.

Your experience with the phone switching between "3G" and "H" is normal and the way it should be working.
As far as speeds go, I'd tell you to possibly change radios and/or check your APN settings to see if you can improve the speeds. These are the usual simple "fixes" for data speeds.

With my experience with unlocked phones... I've tried flashing different radios and it generally improves speeds.
I haven't really had to mess with APN settings though.
So far I have tried: the stock radio that shipped with the device, XXKL1, and XXKK6, with about the same speeds
If anyone has t-mobile and can point me in the right direction for better speeds please let me know.
Also--how fast are the overall data speeds you guys get?

I'm on T-mobile with XXKK6 all stock 4.0.2 and my normal speeds are in the 6mbps down / 2.5mbps up range. My highest are about 9.2mbps down / 4mbps up.

Same here is Dallas... No change sto radio and/or APN.

Has it always been this slow? Maybe your data is being throttled.

No idea... I guess I'll check. It's not slow by any means though just my t-mobile galaxy s2 picked up the signal a lot better since it had nearly double the speeds? I'm in Phoenix so I generally have excellent coverage too...
I'm getting 3.5-4 down and 2.5 up with XXKK6 and franco kernel

The numbers you are getting are pretty normal for TMobile. The galaxy s 2 theoretically should get better speeds, just because its max theoretical speed is twice as fast as the galaxy nexus' on the same network. Your speeds will carry depending on where you are, time of day, etc.

I remember on previous phones including Nexus S there would be a build.prop hack to make your speeds faster. Not sure if it works for the Galaxy Nexus but here they are,
ro.ril.hsxpa=2
ro.ril.gprsclass=12
ro.ril.hsdpa.category=16
ro.ril.hsupa.category=8
Click to expand...
Click to collapse
Add those to build.prop in /system/ (may require additional tweaking since NS is only capable of 7.2 Mbps)

I don't know if anyone is still monitoring this thread, but I went in to a t-mobile store yesterday and watched a One S get 21 meg download speeds on 4g when I can't get better than 3.5 with my GN. I've tried different radios, nothing changes. As though I am throttled at 3.5- which I am not.
Any ideas?

[Q] SGH-T989D (Telus) Slow "4G" on T-Mobile

Hello all!
Noob here, first post, so first and foremost please pardon any ignorance. I did search here as well as google without finding any significant results. I appreciate anyone who takes time to answer.
I recently bought an unlocked Galaxy S2x (989D) for use here in the USA on T-Mobile. I went with the 989D and not the 989 because I'm using a grandfathered T-Zones plan.
I rooted/flashed Juggernaut 5.0 through cwm, and the phone is working fine EXCEPT my download/upload speeds are lousy. Consistently 1.5Mbps down / 500Kbps Up MAX with 800-1200 ms ping via speedtest app from various parts of Maryland (Baltimore/DC corridor) and using different servers. My N1 has always tested faster than that in the same area, which is why I'm particularly concerned.
I tried flashing Telus KJ3, T-Mo KID and T-Mo KL1 modems found here:
http://forum.xda-developers.com/showthread.php?t=1426001
But saw no improvement. I've also tried using the stock epc.t-mobile and the old internet2.voicestream APNs, with equally crappy results on both.
Is it just a matter of T-Mo having terrible speed over HSPA in this area, or is it possible that there's something screwy going on with the device/rom/kernel/radio? FWIW, calls and texts are fine, and wifi calling works as well. I've attached a few screenshots in case any of them might be helpful.
TIA!

hmm... you should read this http://forum.xda-developers.com/showthread.php?t=1514954
there's no spoon
highest speed i ever got was close to 10 Mbps in Canada 3G/3.5G networks
seems more like the area you live in, have poor Tmo coverage for data

That's disappointing, to say the least, especially since according to the coverage map, I'm smack in the middle of a giant blob of "4G Excellent" coverage. I'm still confused as to why my Nexus One would have better speedtest results. Perhaps HTC/Google FTW.

seriously???
Is this legit? Full 4G signal? I can't imagine how it's THIS slow. Does jugg 5.0 have any build.prop tweaks that could be farking with my data? Just threw my sim card into my N1 to compare and it's way faster.

@JoshD422, Did you ever figure this out?

[Q] Whats the difference between each of the radios?

I am also wondering about this same fact with a real Telus phone in Canada. I'm also wondering about the difference between the 3 radios that were provided with the Darkside.UCLE2 Beta 5 ROM. (Don't get me wrong, appreciate all the hard work from these guys, amazing where the T989 dev has come already!)
I tried all 3 radios, and get different speeds with each one. Blazes 4G radio I can't seem to tether, and then the T-mo radios I'm having issues with Bluetooth and even Data.
Could someone if you have a minute explain what the difference is between the radios and maybe suggest what radio would be best for us Telus users in Canada?
Cheers, TIA!

JoshD422,
I will be the first to tell you living in Toronto, that its completely unpredictable in Canada.
I've had areas if there is high use downtown I will get even worse results than that (seen a ping of over 1000ms ).
At the same time I can redo a speedtest about 200 metres away, and get results up in the 10 Mbps and pings of 45 ms. So I don't believe that part has to do with the radios but more the quality of service, and I'm in whats supposed to have the best service city in Canada.

Your problem definitely seems to be due to the T-Zones plan. I don't have that plan and I'm using an unlocked stock Telus T989D in Maryland and I get 2-4 Mbps down and 0.7-1.0 Mbps up

Do you get the "4G" icon?
I am on a stock unlocked T989d in the Atlanta area and get similar speed to you. However, I only see the "3G" icon in my phone.

Yes, only "3g" icon in MD/DC area. I guess maybe perhaps this is not as fast as using the T-Mobile radio software that comes stock in the T989, but it's plenty fast for me. I don't think the "4g" capability is much faster, anyway.

I think the "4g" icon is purely cosmetic. I have an unlocked Telus T989d on Tmobile and my co-worker has the Tmobile T989 on Tmobile. We both did a Speedtest side to side and we both got ~12Mbps down, ~1.3Mbps up. My phone was showing the 3g icon, while his was showing the 4g icon. Both our networks showed up as HSPA. Both of us in our respective stock, un-rooted ROMs.

While T-Mo roms do tend to be a bit over zelus with the 4G icon, it is much faster than a 3G connection. Where I live in Orlando is a 4G area and I get over 20mbs download speeds and over 2mbps upload speeds..
Side note though.. it is funny that people still use "" or call it 3.5G when the T-Mobile network has been accepted as 4G for almost a year now .. I tried to find the artical but its being illusive today..

Officially, 4G is supposed to get 1000mbs peak download. Tmobile uses HSPA+ which peaks at ~80mbs. I think that is why people call it 3.5G or use the "4G" when talking Tmobile.

Rogers download speeds

I'm currently on Rogers Canada right now. I have the Gnex NON-LTE version. I've been doing speedtests on my device and I've constantly been getting around 250kB/s, usually less. There are a couple times where I reached 850kB/s but most of the time just 250 which is quite slow. I've tested this in open areas.
The baseband it came with is UGKL1. I've been downloading stuff and usually I get around 250kb/s or even slower.
I now switched to the newer radio UGLA4. I am getting about the same results. Once or twice I did speedtests and got 640kb/s.
My feeling is that its Rogers network that's constantly giving me poor download speeds. Does anyone else have faster speeds with non-LTE Gnex on rogers? Any solutions? I've looked around but to no avail.

I just tested mine (Rogers Network) and I was getting a consistent 1mb/s upload and download. I do however at the moment have a good quality hspa connection.

That's not the LTE version right? What baseband are you using and where are you located in canada? I'm in the Vancouver region.
I think I partially figured out the reason why I'm getting slow speeds. I'm currently using AOKP ROM (milestone 4). There's a power saver setting where if I'm idle for a certain amount time (ie 10mins) it turns my connection to 2G. Yes I set that up. Once I wake my device it turns 3G/HSDPA back on. However going into the secret menu (*#*#4636#*#*) I noticed that the preferred network type is set on "GSM/CDMA auto". This is likely the be the issue, if I want HSDPA it should be set on WCDMA. Now I've set that to WCDMA Preferred. Doing a speed test I'm getting speeds of 400-500kb/s. That's a drastic improvement. However upload remains to be the same at around 150kb/s. However keeping the power saving option it reverts back to the "GSM/CDMA auto" after idle time.
I don't think I have quite solved my issue as this device should be about to download/upload at faster speeds. I'm going to change back to my old baseband and see. Please let me know the details about your phone, thanks!
Edit: I see you're from PEI. Let me know your baseband still, thanks!

That doesn't sound like a radio problem, sounds more like a tower problem. Have you triend driving around ant testing your signals in different places? I usually get between 2,5 and 9mps in and around montreal. Where did you try? Were your four signal bars on with the H and the arrow?

Yes I have. I get about the same results. I have tried both open areas and inside buildings. I just reinstalled old radio and my speeds with WCDMA only enabled gets me about 300+kB/s.
Just to clarify my kB/s or kb/s is kilobytes for seconds (not bits).
I doubt we should be having tower problems in Vancouver though....

So I tried driving around more with the new baseband I got about 1000kB/s. Upload was still slow at around 200kB/s. Any reason why? I found some people believe that rogers caps the limit but still too low for me.

Could possibly be your carrier throttling the speed? For most users 250kbs is more than enough.
I have the gsm version and live in the UK. If I get 2.5mb download speeds over HSPA I consider it fast!

I'm on Bell, I get between 6-9Mbps down and 2.5-3.5Mbps up consistently.

Yea it's been pretty much up and down for me. Most of the time I get around 500kbyte/s and around 230 indoor. Upload is just pure crap for me outside or in. I've been getting around 150-200kbyte/s, mostly 160ish. Sometimes I even get 80kB/s. This is a problem and I don't know if its the phone or just poor coverage. I'm leaning towards poor coverage as I did manage to get a fast 900kbyte/s download and 250kbyte/s upload.
To those moving to mobilicty, honestly the coverage with them is worse. I can't stand dropped calls. I have friends who are on both wind and mobilicity and they tell me about the dropped calls. I sometimes have to make important calls and dropped calling is a nono. They can deal with it but for me I can't.

I've been with Mobilicity for just over a year now and I have never once had a dropped call. Coverage is poor though I've just never been on a call with poor coverage I guess. Basically if you stay editing the gta minus oakville you will have no problems
