[Q] HSUPA Disabled (Rogers)?

Hey, I just got my Galaxy Nexus in the mail today and noticed I was getting pretty good download speeds 4-5 Mbps however I seem to be capped at just under 400 Kbps for upload.
I am on Rogers in Canada.
Is HSUPA disabled by default, any way around this? What speeds are you getting on your upload when connected to 3G/HSPA+?

Its probably rogers capping your speed.

Unfortunately you may be right. Just popped my sim card back into my Nexus One. Lower download speeds but exactly the same slow upload.
They didn't use to do this. Thanks Rogers!

Wait for a different radio to pop up. Flash.
That's a quick way to remove the upload limitation. I did this only Nexus S (KB3 radio) and the upstream was consistently over 1mbps.

Run a getprop (in ADB shell or terminal on your phone) and see what ro.ril.hsxpa is set to. Back in the Nexus One days you had to set that to 2 to enable HSUPA if you ordered it from the US like most of us did over here. It would be kind of strange if that was needed still though.

It seems this ro.ril.hsxpa parameter isn't set to anything on the Galaxy Nexus.
I have tried setting it to 2 and 3, neither appears to make a chagne in upload speeds.

Ok. Good to know. Didn't think it would be needed as HSUPA should really be default now basically everywhere and non-HSUPA networks still worked fine with that setting set to 2.

I've talked with Rogers and they claim to not throttle their upload speeds. It's possible it may just be the towers near me.
Can someone else on Rogers post the speeds they get on their Galaxy Nexus (or any other HSPA+ phones)?
On the download side of things I have seen up to 13Mbit, not bad at all but I can't stream anything from my phone because of the upload speeds.

What baseband do you have? Every UCxxx radio I've tried was capped to 400kbs upstream. I run XXKD1 and get full upstream speeds as well as faster downstream. 6M/3M isn't uncommon on the newer towers. (I'm using a Nexus S so your mileage may vary)

i'm on Rogers with the Galaxy Nexus and my speeds are alright
using modem XKK1
i get download speeds averaging around 3-5mbps and uploads from 1.5-2mbps
sooo im pretty sure its just your coverage area
i havent modded anything in the build.prop file either

I contact Rogers and after about 4 or 5 days I noticed that my uploads speeds were back to the normal ~1Mbps.
Speeds were back full speed on both the Galaxy Nexus and Nexus One at that point.
So if your having speed issues, contact Rogers, hopefully they can do something.

If his 400kbs speed is right then I'll still guess it is a capped radio. Even on old towers you can get faster speeds. The tip is that is is a consistent 400kbs or slightly lower. That's a UCxxx radio, have seen it many times. I have no idea why that group of radios are capped but for sure they are, if that's what he has.

I'm on Rogers and everything seems fine.
8140 down / 2614 up

In a decent coverage area, I get 7.5mbps down, ~1mbps up. Rogers doesn't seem to be capping or doing anything strange.

Yes i was also on rogers and noticed that i never ever got above 1Mbps, which was usless i find if i was doing VOIP on googlevoice.
I switched to bell and notice i always have a constant 3-4Mbps up peaking at 5-6.
Not sure why rogers lacks their network since they've been around for a long time running their network and upgrading.

GN owners on AT&T. Which Baseband?

For you guys with Galaxy Nexus on AT&T, which baseband do you have it installed? UG or stock XX? Just wondering which baseband offer best signal quality on AT&T.
I had UGKK7 up until last night and I like it overall but I just found out yesterday while going out with family in downtown Seattle area that my data connection suck. Basically it is really really slow or I get no data connection when I try to browse. At the very spot that I had very slow data connection or get no data connection error, I was able to use my wife iPhone 4 to browse internet fine. Although a little slower to usual, it was able to get on internet and browse fine.
So I was wondering which baseband you guys using on AT&T network?

I am currently using XXKK1 and have no issues.

stock here. faster down and up and the wife's iphone. make sure you are previsioned for the 4G data plan.

Not on AT&T but on T-Mobile, XXKK6 for me.

XXKK1 on AT&T with no issues.

Thanks guys. I just installed XXKK1 this afternoon. So far everything is running fine. I need to take a trip to downtown or mall setting where there are lots of people to really test this out.

hmm, best bet is to borrow a friend who has one of the AT&T 4G phone (inspire, infused, atrix). pop in your sim, call att to have them grandfather you to the unlimited 4G smart phone plan.

Currently using XXKK6 and it stinks over K1. My uploads are about the same, but downloads are about half.

UGKK7 right now. But these modems are region sensitive so you have to trial and error to find the best one for you.
Initially stock XXKK1 didn't give me good signal strength however data speeds were consistent within 2.0 - 2.5 mbps. With UGKK7 signal strength is a lot better than XXKK1 in most areas where I usually go (30 mile radius from Philly) however my data speeds are not consistent at all ... now I see anywhere from 700 kbps all the way to 6.5 mbps.
I am sticking with UGKK7 as it gives me the best signal (min 4 bars) and data speed (2.0 - 2.5 mbps) at home ...

That's awesome about your Dad, heck there's a good chance we've crossed paths In New Braunfels I get anywhere from 6-11 on downloads, which is plenty fast for me. Fyi, I'm actually the admin of one of the largest Texas Mason websites: www.masonsoftexas.com there are a handful of others on xda as well.

Anybody using The Ugk ones on ATT?

XXKK6 here
if you want to flash custom rom and stuff
i think u have to have XXKK6 or later baseband
tried UGKK6, UGKL1 and XXKL1
not much difference honestly
so went back to stock XXKK6

[Q] Best radio to use with Galaxy Nexus on T-Mobile USA

So the official GSM version of the Galaxy Nexus (http://code.google.com/android/nexus/images.html)
is supposed to have xxkk6 radio (radio-maguro-i9250xxkk6.img)
I read in another place that the Asian varian has a different radio, and the canadian varians also have different radios. So being that the GSM Galaxy Nexus is not officially in the US on ATT or T-Mobile I was wondering wich radio is best to use on the T-Mobile network?

North American code is UG, I think UGKL01 is the newest released radio.

I'm using XXKK6 - it's been working fairly well for me. Probably gonna try out one of the UG roms.

i'm currently on UGKL1, live in denver colorado (where t-mobile has 4G coverage) and i dont get any type of HSPA+ speeds, on a good day my down is only 5891kbps and my up is a mere 1243kbps (same speeds as my Nexus S).
maybe US radios are optimized for CDMA networks, i'll switch to XXKK1 later and see if it helps - anyone actually get 4G speeds yet? if so, which radio are you on?

Probably best to use a UG based radio if you're in NA. I'm on UGKL1 and it's fine. I accidentally flashed an XX radio before and data would cut out a lot...

i updated to stock 4.0.2 for tmo and i'm getting 10mps down and 2 up around my area of the woods.

If your tower doesn't have any more capacity available, it doesnt matter what *you* do. There's only 21mbps (or 42, depending on where you live) per tower sector to go around to every user in your sector. If it's 21mbps, all you need is 3 other active people on your tower to get those speeds (factor in radio link loss too).
Long story short, not a single thing you can do to control your speeds. And judging a radio's "ability" based upon speed test results is extremely inaccurate.

And the nexus only reaches 21mbps on T-Mobile anyways so there's that. The north American radios are optimized for Canada.

So my area JUST got 4G on a partnered carrier that TMOUS shares. Im getting 4g on my Sensation but am thinking about getting the GSM Galaxy Nexus. We went from Edge to 4G. All i want to know is if i will be able to get 4g on the Galaxy Nexus for TMOUS?

If you get it on the Sensation theres no reason why you wouldn't get it on the Nexus.

I was using the KK6 radio that came with my phone (assuming it was a UK one since it had a UK style plug in the box) but within 2 days of getting the phone I had dropped signal errors where only a reboot would fix it. I moved to UGKK7 and haven't had any issues since. Pretty sure my speed is slower though (haven't testing yet) so if you have no issues with KK6 keep it.

i've been on KK6 for about two weeks now, speeds never go above 5.5down - i guess i dont have very good HSPA+ coverage north of denver. i also have to turn on and off airplane mode once a day to fix connection issues.

I'm using XXKL1. I get speeds near 5-7 Mbps. Sometimes 9-10 if I get lucky.

I'm also in Chicago on the xxkk6 radio and I never seem to be able to get above 3-5mb down and .5-1mb up. I've also noticed that it shows "3g" as the connection status most of the time, save for when it momentarily shows an H at times.
Anyone have a clear answer on what is displayed when you attain an HSPA+ connection w/ this phone? I find it weird that with the dense 4G coverage in Chicago, I can't seem to get any better speeds than what I get w/ my N1.
Cheers, dudes.

Those sound like pretty standard 4g speeds to me. On a good day I get 10mbs. It really depends on how many people are sharing your tower. People with Verizon LTE are reaping the benefits of new technology without many users.
As for the icon I believe the GSM radio switches to 3g when no data is being transferred and switches to H when active to save power.

[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.

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

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.

Is it normal/acceptable for "4g" speeds to be less than 2 Mb?

About a month ago my area upgraded from EDGE to HSPA+. I finally decided to play with the speedtest.net app yesterday and I was only managing download speeds of maybe 1 or 2Mb, on a good test. This is enough for casual use, I suppose, but most people (on this board at least) seem to be getting much better speeds than that. A nearby area where the State University resides also produces similar speeds on my GNex and my previous phone (AT&T Galaxy S2).
Is this normal or do I need to change something on my phone?

1-3mbps is pretty normal for me indoors with 2-3 bars of signal, with 4-5 or so outdoors with better signal. I can only pull down those crazy numbers of 10+ with HSPA+ late at night when the towers aren't as busy. I'm in a small town, but we've had HSPA+ for a good year or more now (heck, I was on Verizon when it was switched on, so I don't know exactly how long...). Maybe your network is still getting upgraded / installed and the process isn't done yet?
I'm on the T-mobile $30 plan, by the way. I've heard AT&T's HSPA+ can be significantly slower in some places, so that may be part of it?

if they just rolled out the towers a month ago and upgraded to HSPA+, I'm not at all surprised by those speeds.

Att's hspa is notoriously slow compared to Tmo. I see between 6 and 18 mbps on my Tmo phones and my Att phones max out at around 6, averaging around 3.
For an area that just now got hspa turned on when the rest of the country is getting LTE, those speeds you are describing seem perfectly normal.

T-Mobile's "4G" in Phoenix is exactly the same speed as my 3G Vibrant.

I would be happy to get 6Mb down with AT&T in Austin. Max is about 3.1Mbps which I think is crap since we know it is capable of more. Interestingly, AT&T LTE in the same areas rock!

Well that's also because T-Mobile has HSPA+ 42mbps deployed, and devices that can make use of it. Most AT&T devices are at best 21mbps capable, and not all of their towers are.

Depends on signal strength. On VZW LTE I can pull 20+ mbps in Seattle, but only 2-5 mbps in outlying areas.

"4g" in quotes, and OP specifically is talking about AT&T.

I'll have to run speedtest some more when I'm out of town and see what kind of numbers I can get. I would be interested to see what speeds a 3G phone gets in the same region as my "4G" Gnex (HSPA+ via AT&T, not LTE via Verizon).
