Poor performance on SpeedTest.net (GSM version)

Hey all,
I live in Chicago and have a GSM version of the Galaxy Nexus using the T-mobile network. Honestly I have never gotten more than 10mbps download and often get less than 5mbps. My ping is also very unstable sometimes its 1000+ or its 100. Is there something wrong with my 4g radio? As a comparison my gf's Samsung Galaxy S II gets 15mbps or better.
Thanks

Here in Baltimore my tmo galaxy s2 pulls 10 to 12 mbps and my gnex on tmo only gets about 5. Don't think there is really anything wrong with the gnex radio. Its just not best suited for tmo network as good as the tmo branded sgs2.

does your gnex show 3G when you are not browsing and then switches to "H" when you are?

Try flashing some radios. Ug--x radios are for north America but it seems a lot of people do better with Europe radios on T-Mobile which are XX--X.
bow chicka wow wow.

Try different radios to see if it helps. The T-Mobile SGSII will always get faster speeds because its a 42mbps HSPA+ device, whereas the GNex is a 21mbps HSPA+ device.

This is how it should be. This is how GSM/HSPA+ devices work. It saves battery.

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.

I'm on T-Mobile and 1-2Mb is normal for me with 5 bars. If I'm extremely lucky I sometimes see 3Mb.
T-Mobile's "4G" in Phoenix is exactly the same speed as my 3G Vibrant.

True, location also plays a big role.

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).

[Q] Throttled 4G Speeds

Anyone else having insanely slow 4G speeds on their Android devices after the iPhone 5 release? I did a side-by-side speedtest on the same server, 35mbps on the iPhone 5 and 5mpbs on the Galaxy Nexus.

I do believe the iphone 5 is lte and the galaxy nexus is not, just hsdpa. The lte network also has fewer phones currently due to being new and only in few markets.

The 2 cdma (sprint and verizon) variants of the galaxy nexus in the USA are lte devices.
@op, no. On verizon results are right on par with previous speed results with lte on the nexus.
good day.

If LTE was being affected, it would slow down speeds for both phones assuming they're in the same place on the same network (and tower). The iPhone doesn't have its own separate network...
One phone getting 35mbps and another 5mbps is a fluke. They should both be roughly the same assuming they have the same signal strength.

and assuming you used the same location (as in the server location) for the speed test.

Yep

verzion bc it has many tower... if there is no tower close by then you will not get 4g or 3g u will be on edge..
how i know.. my co-worker called up sprint to see whats wrong with his samsung galaxy s3

Is it possible the account for the nexus is in the 5% that gets throttled on high traffic towers?

[Q] Download speed??

Hi all,
My question is does the Note II have a weak antenna compared to Note1 or does the Note II comming from Korea need an Aussie CSC/Modem to be able to performe at its peak in Aussie?
I finally took the plunge and bought the Note II.
Managed to Root, CMW, Back up with CMW and Tiatanium, also backed up EFS.
Still on stock as much as possible and mostly happy. The phone is vey smooth and fast. (came frome Note 1).
My question is related to the data speeds. I have a N7105 (SHV-E250K) from Korea, and the data speeds on the Aussie network Telstra are the fastest and slowest Ive seen.(see attached).
On my Note1 the speeds were constantly reasonable and I could live with them. ( I live about 1/2 hour from a large town). Note 1 could pick up 3G where I live, The Note II won't. Note II looses 4G and 3G soon after leaving town. Note 1 keeps getting 3G all the way Home.
As can be seen the 4G speeds are amazing. However not sure I can live with the G speeds

Speed ​​is affected by too many factors, one by one, to clarify a bit difficult

Agreed, but the difference between 40Mbps and 0.02Mbps cannot be explained by network congestion. All speed tests were outside (so no building interference) on a clear night. My thoughts are either hardware (antenna) or software (VPN/CSC). Could be wrong, but it is a huge drop to be explained by anything else. :-\

G=GPRS its not going to be fast....
3G yes
H even faster
H+ Faster still
Then 4G
So yeah G icon in speed tests are going to be slow as hell

Okay, Maybe I should have been more clear.
When I'm in the 4G area Note 2 shows 4G is Fast++, Note 1 shows 3G and is fast+.
In the 3G area Note 2 Shows G (sometimes 3G) and is slow (reasonable speed when 3G shown). Note 1 shows 3G and is fast+
in G area Note 2 shows G and is very slow. Note 1 also slow but picks up 3G most of time (speed okay when showing 3G)
Basically Note 1 shows 3G in most areas whereas Note 2 only picks up 3G/4G near and in town
Will try to get a side by side comparison of the two phones in the same areas at the same time and screen shot

Note 2 sounds like my S3 If your not in a strong 4G it tends to go back to 3G a lot got to be Samsung radios (modems)

I think I know the source of your problem and hope the forum can solve it with a s/w Rom fix/advice...
Simply put you need quad band for UMTS(3G) to work properly in Oz.
E250K has UMTS(3G): 1900, 2100
N7105 and N7100 has UMTS(3G): 1900, 2100, 850, 900 aka quad band
For more info see google wiki whirlpool for frequencies used in australia and
Google wiki GN2 versions - I would have it the links but I'm new here and it won't let me (spam prevention).

H+ or 3G what is the difference?

every time i browse the net on my Note 2 I'm getting "H+" on the status bar in my area while at the same time whenever i call someone i get 3G at the same place, so what is the difference between them? which is better? sorry if it is a noob quastion

H+ is for HSDPA+, which delivers much higher speeds than normal 3G. Technically it is an upgraded 3G network. so if you have H+ then your network is faster than if you get only 3G. and H+ is used only for data download. so you will not see it in normal voice calls.
Based on your network, Note II can handle H+ speeds up to 42Mbps. 3G is only 384kbps.

Capable of 42Mbps!? I can't imagine anyone ever gets anywhere near that. I only get 35Mbps on my home computer with cable internet.
With H+ in my area, I generally get somewhere around 3Mbps maybe a little higher.
What is the max speed of LTE supposed to be?
Now that I know my phone is capable of 42Mbps (which is faster then my home connection), I really have no problem with not having an LTE phone. Especially since the max speed is probably as probable as seeing a unicorn.

Not to put a damper on it, but H+ doesnt mean DCHSPA as my N7100 shows that symbol and its not DCHSPA capable.

That's because H+ means HSPA+. Unless that's what DCHSPA is, but I've never heard it called that before. Even then, are you sure about that? HSPA+ is listed in the specs for this phone.

HSDPA, 42 Mbps; HSUPA, 5.76 Mbps; LTE, Cat3, 50 Mbps UL, 100 Mbps DL
H+ is faster than 3g without a doubt
DCHSDPA is known as dual channel ie three uk are dishing it out but us n7100 owners nothing to get excited over its not supported..
Mainly only lte models have dchsdpa only a couple of non lte devices have it

Well, that sort of clears it up. (Although I don't fully get it, I sorta do) Not like it really matters though. No one is going to get anywhere close to what those technologies are capable of anyways. If they ever do, we will probably all be on our next device anyways(probably more like a few devices down the road).
