i9020a slow 3g speeds?

I just migrated from theN1 to the NS and my 3g speeds seem slow in speedtest. downloads are around 2000kbps which is usual for the rogers network in my area, but uploads are around 60-80kbps and pin times are almost 200ms. I'm using the Koodo version on the Rogers network.

Updating the baseband to KB3 or KD1 should fix up your upload speed.

Are those radios compatible with the 9020a?
Any links to them?

I've successfully flashed both of the following radios via fastboot onto my i9020a (after extracting the radio.img from the zip of course):
KB3 http://forum.xda-developers.com/showpost.php?p=11742701&postcount=1
KD1 http://forum.xda-developers.com/showpost.php?p=13315514&postcount=122

I flashed the kd1 radio and my ping has improved as well as download speeds. Upload is still stuck around 60kbps

Hmm that is strange, I was running cm7.0.2 with KB3 and KD1 and had normal 1.1-1.2mb upload speeds. Over on hofo there was a thread where quite a few folks were complaining about capped upload speeds with the NS, people were focused on the source of the issue being the KB2 radio, but it is seeming more like some sort of network issue in Quebec and Ontario as I have never seen capped upload speeds over multiple android phones here in Vancouver. It may be worth doing a nandroid backup, wipe and CM7 reinstall just for testing purposes though.
Here are a few threads that may be helpful:

I'll put my SIM back in my Nexus One and retest. That should rule out network problems.

This is clearly a local Montreal issue. I'm in Toronto this week and HSUPA is almost 1000kbps.

I am experiencing very slow 3g data speeds with my i9020a (AT&T US). I have never gone above 400kbs down on full bar 3g signal.
What's the deal here? I thought the i9020a was compatible with AT&T bands? 3g lights up, but data is just slow. My baseband after the 2.3.4 update is I9020AUCKD1.
Is there a radio flash I can do to get 3g speeds? If not, this thing is going back to Amazon. It's very annoying.

Just went to an AT&T store and they guy changed some settings on my account (I had a 4g plan with my Atrix). Initially, this resulted in faster speeds, but now they have dropped back down to like 300 kbs down on 3g and 100 up on 3g.
I'm so irritated with this. I'm most likely going to return it and go back to my Atrix. It sucks bigtime as I really like the Nexus S.
Is there anything else I can do to speed this thing up on AT&T? Surely there are others who have the i9020a on ATT in the US?

I too have an i9020a on ATT in the Denver Metro area - I applied the 2.3.4 update and saw abysmal upload and download speeds with the bundled radio. I flashed the KB3 radio and immediately saw improvement - consistant 2.0Meg down and 1.5 Meg up. I then went into the ATT store and switched my plan (was on an iPhone and thus had strange voicemail issues on the NS) and since, my data has been significantly slower (1.0 Meg down and .5 Meg up)...
I'm headed back there tonight to see if there is an issue in my account - otherwise, I'm going to start looking into the build.pref changes that others have referenced in the forums...

EVO SHift 3G Network question

I don't have cable internet where i live due to the fact i travel to and from class way to much to use it. I tethered my phone via wireless or usb to my computer and run off of the 3g network speeds. I currently switch between CM7 and then new EVO Shift 2.3.3 leaked GB Test ROM. I noticed that i have 57% signal according to opensignal and when i download anything or load web pages they are very slow no matter how many bars i have. My download speeds are usually around 20kbps to 55kbps max Is there anything i can do to increase the net speed of my 3G connection? Or is there a app on the market place that i can use to improve or some how boost my 3g network speeds.

I've noticed a little bit slower speeds using the Gingerbread leak but nothing as slow as what you are experiencing. Have you tried the fix from this thread? [FIX] 3G Upload & Download Speeds

Sprints network for Michigan, Ohio and all its surrounding states flat out sucks I get them speeds daily and all Sprint keeps doing is knocking 20 and 50 off my bills, I don't care about money off they either need to fix their network or that roam controlling app is going to get me out of contract etf free I don't care to pay good money for good service but when I pay 160 a month for 2 lines I would expect to be getting the 3G Sprint lies and says I get,

Ah is that what it was. I flashed a new rom the other day with the sense 2.1 and everything was cool except the 3g data speed. It was taking 5-10 minutes to download a 1mb file so I had to restore my other rom lol. My normal 3g data speeds are over 1mbps which is super fast. I couldnt even browse the web with the leaked build, it was ridiculous.

Wow when mine hit 700 kbps I thought that was fast. I came from T-Mobile and was getting 2-3mbps on their 3g also my girlfriend uses Comcast to go which uses the Sprint towers for the service and she gets 1.5 to 3 mbps speeds

hey
going to try what one do you guys do "1.17.651.1 RUU (Stock):" or 2.72.651.2 RUU: i dont have 4g here

i believe 1.17.651.1 ruu is the stock version that's already on your phone, for people that want to flash back to stock settings if the new radio fails to perform. you should flash to 2.72.651.2 if you want an attempt at an upgrade. personally, it did nothing on my end for the internet, but voice calls did slightly improve. i encountered problems too, where it would hang on the htc splash screen. i don't have an sd card adapter... so i had to put my micro in my old htc hero, run that as a mass storage unit, delete PG06IMG from the computer, boot into bootloader, delete everything, clean cache, davilk (i think that's what it's called), and re-load from nandroid backup. after that i saw 1.08... in about phone, baseband version so i guess i was successful lol. pain in the ass, but will further test it later outside and stuff... once the heat drops down over her in n.y. :]

Besides the fact that my 3G speeds crawl. My 4G is SLOWER on occaison than my 3G. Lol, why is this and how can I fix? It all started when I first flashed cm7

I was wondering the number i had to enter to access the network settings for the mikshifted 2.1 mod. I tried to enter ##3282# and no luck with that . I noticed that my 3g speeds were 20kbps and its horrible lol. Have flashed the new radio on a previous version of CM7 and Kingdom 3.0 rom and didn't work so hot for me. Anyone have any recommendations?

Slow data speeds Philadelphia suburbs possible fixes?

Anyone else live in this area and experience slow data? Fastest we've recorded was 1.5 mbps. Avg is 300-500 kpbs downstream. Tried to verify all APN settings with 4 different roms, these were correct. No change in speed.
Anyway to verify the radio is working correctly? I'm starting to wonder if it's hardware issue. (settings show hsdpa connection) I've tried stock radio, ota radio, and most recent the M2 radio. M2 has fixed gps problems, but still have slow data.

Using Mikes latest atm, I'm using the recommended radio for this ROM (the ROM contains the correct RIL files).

I live in the burbs as well, but the fastest I've gotten is about 3mb down / 1mb up.
Normal speed is around 1.5mb down / 1mb up.
Not as fast as others, not as fast as I expected, but still not terrible either. I've found the updated OTA radio the best. Maybe try flashing a different ROM and make sure your're using the correct RIL for the ROM your using. AOSP Roms use the G RIL I believe. Sense ROMS use the HM RILs.

I don't live there but travel there from day to day. What you 2 are getting I got also. I make it a point to check data speeds wherever I go. Speeds are much better in Harrisburg and York area.

Guess this is enough for confirmation, I've been going crazy trying to get 3G speeds...basically I'm getting edge 90% of the time.

[SOLVED] Horrid Network Speeds (not just mobile network)

Hey everyone, I was wondering what kind of speeds I should be getting here.
On the mobile network I get most of the time less than 2mbps, around 1.5-1.75, I ONCE got above 3mbps. That's download, upload is a dismal 1.2-1.5 mbps.
I thought maybe it was just where I was, bad cell tower, etc., but check this. My home wifi is reasonably fast, I get 12-16 mbps down on the computer with ~3mbps up. On my phone, connected to wifi, gets 4.5mbps down and just under 2mbps up. This shouldn't happen, should it? On my old mytouch slide, in the same room I'm in right now, I got 3-4mbps consistently over the mobile network (not even HSPA+, just plain old HSPA), and at LEAST 7 or 8 mbps over wifi, on the same wifi network. I'm very confused here, why is my HTC Sensation, which is supposed to be the latest and greatest, getting such terrible speeds? Do I have hardware issues? It's the same dismal speeds on every ROM I've tried. Stock before rooted, stock after rooted, arhd, cm7, everything is horrible. Should I call t-mobile and ask for a replacement? I just can't figure out why I'm getting slower speeds on HSPA+ than I was on 3G HSPA. Yikes.

Make sure your radio and RIL are correct (search the RIL and Radio threads) ... if you've tried different ROMs you may have over-written something.
I consistently get 16-20 MBPS down 10-15 MBPS up speeds on my home wifi (Verizion FIOS 25/25 service).
Get Wifi Analyzer from the market (free) and make sure you are not sharing WIFI channels with your neighbors.

My baseband version in about phone reads 10.58.9035.00P_10.15.9035.02_2. I think the radio that they test CM7 with is 10.56.9035.00U_10.14.9035.01, so I suppose I COULD downgrade, but I was having the same issues even before I rooted. As for RIL's, I know what they are but I have never come across them. I don't know if they're built in or if I have to flash them or even where to find them.
I have noticed HORRIBLE wifi reception with this phone. I can never connect to the wifi at my school, and at home, I can hold the phone right next to the router and it will still be 3/4 bars of wifi. Right know I'm in the room right next to the router and it alternates between the little dot of the wifi icon and the 1st bar. My computer gets 5/5 bars. My cell reception has seemed to be normal though, haven't noticed any huge issues. In fact, it seems to hang onto 3G/HSPA better than my old phone did. My old phone constantly bumped down to edge in my house. Speeds suck on this phone though, and I can't figure out why.
I tried that app you suggested, didn't find any interference, but saw how stupidly low my signal strength was. Here's a SS, attached.

Bump,any ideas?

Check the antenna contacts on the back of the phone; try bending them up to engage the pads in the cover.
Failing that, return the phone for replacement.

I decided to do a test as I have been experiencing substantial drop in DL/UL speeds utilizing my personal favorite CM7.
Radios varied with CM7 reco through latest HTC radio. Stock & OC kernal. Observation.
Dozens of tests. 6+ DL 2.5 Mbps UL.
Wi-Fi- Avg expected speeds 31 Mbps DL 6.50 UL Mbps. ( Wifi signal was extremely erratic). No fix.
revert back to Sense 3.5 NRG rom with 169 RIl matching radio.
Stock kernal.
Dozens of tests. Avg 9.25 DL1.50 Mbp UL
Wi-fi- same as CM7 however signal is perfect.
FWIW- complete stock sense posed higher DL/UL. Odd but how much stock I put into this?
Benchmarks- with both Cm7 & sense OC kernals.
Both scored heavily using the most common benchmarks.
AnTuTu-6381
CF-7667
Quadrant-3810
Stock kernal- nothing to write home about.
Other then the data speed, in terms of user experience, difficult to say. Other than I was always plagued with accurate gps lock using CM7.
I'm all over the place regarding the breakdown but I don't have much patience right now.
Enjoy.

Typical WiFi performance for me at home (fastest is ~20 D 10 U). Router is at the other end of the house (blue on the graph). If you have strong signal, look at the software (radio + RIL), if signal is weak check antenna.

So I guess I'll try the recommended radio. How do you check which RIL you have? I don't think its the radio though, since I had the same bad speeds on stock s-on before rooting. I'll try checking the antenna connectors in the casings. If I do have to do a warranty exchange, will I have to get the phone back to s-on to be under warranty?

Regarding RIL check- Run getprop gsm.version.ril-impl in Terminal Emulator (Download from market if you don't have). Takes 2 seconds to get RIL which will show 169, 173, etc...
Regarding exchange- I'm assuming you will have to revert back to S-on but I could very well be wrong, however I know for peace of mind, I would do this to ensure a complete hassle free exchange.
Wish I could assist more.

ahahaha.
i live in italy. I paid 19 € so about 25 $ for a bad connection of 7 mega in download and 0,45 mega in upload, but the real speed is 4/0,3
for curiosity how much do you pay in United states???
return to your phone, probabily you can to flash other radi.img

I am on a shared plan, but I think for just me, 4G data is $20/month, which guarantees 4G speeds up to 2GB of usage, then it starts throttling. I did check my usage, I'm under 1GB.
Checked my RIL against the RIL thread that's stickied in the dev forum, I have 2.2.1073HMQ, which is matched to the 10.58 radio that I currently have. So it can't be an RIL issue.
I also tested the speed of the data connection through a wifi hotspot on my computer. I still only got about 2 mbps on the computer, maybe 2.5, don't remember exactly. Definitely under 3 though, which is unacceptable. I think I'm going to call t-mobile, because I'm supposed to be in a 4G coverage area. But on top of that, my wifi speeds suck as well, which tells me it's not just network coverage, it's something to do with the wireless chipset, something isn't working correctly. I think I should be able to except AT LEAST equivalent speeds to my old 3G slide.

Verizon FIOS @ $100/mo gets you 25/25 fiber to the house, phone, and a few hundred channels of hi def TV. Wireless router included gets up to 20 MBps to the phone.
Sent from my Bricked Energy ROM Sensation.

So I called t-mobile, the first guy said he thought I knew what I was talking about and had tried everything that he had ideas for, so he sent me to tier 2 support, and that guy told me that it was probably something faulty in either the back of the phone (antenna) or the radio controller. He thought my wifi and cell speed issues were related. Since I got the phone at costco he suggested I try to do an exchange through them since I'd get a new device in exchange instead of a refurbished one. I'm going to end up going that route.
So here's my question now, once I get the new replacement phone, since it's the same phone, is it possible to take a nandroid of my current phone how it is and then restore it after I root and get s-off? Or would that not work since the phones would have different serials and IMEI's? It would be so much easier if I could just nandroid restore after I s-off, root, and get clockwork.

Yeah, only sense roms don't differentiate between 3g and hspa. I've tried in different cell towers where I'm supposed to have full 4g, and I don't. I have maybe 2.5 mbps, most of the time 2 or below. I'm exchanging my phone Friday at Costco so hopefully the new one is different and I don't get one with the stupid ssharp screen. I like this Acer one better.

[Q] Data Speed Issue

Every time my phone switches radios (Edge, HSPA+, LTE) my data speed seems to be throattled. I would have to reboot the phone to correct the issue.
So for example, I ran a speed test on LTE the results 20Mbps. Then I switched to HSPA+ then switched back to LTE and ran a speed test. Initially it would connect to 10Mbps immediately afterwards it would slow down to 2 to 3 Mbps. It would stay like this until I reboot the phone. I used Odin to flash back the stock from...still the same issue. Anyone have any ideas what's causing this problem?

Woot! im not the only one
I am on the same rom in Vancouver. The first day it was fine...i get nice consistent speeds but when i run the speed test now, it jumps up fast and then throttles down to 2-3 mbps!!
I remember i cleared cache and ran it again ,seemed to fixed the issue for a day or so and now its back to 2-3 mbps. Upload speeds are usually higher too.
Any ideas?

try different rom and kernel see if that fixes something.

I just started experiencing this in the past two weeks. I used to have to restart my phone to fix it but now I just enable then disable flight mode and I get the usual LTE speeds again. Much faster than reboot. I'm also on Rogers, stock ROM.

I guess its not just me. What about ur HSPA+ and edge speeds rates?
For hspa+ I'm only dl'ing at 2Mbps and for Edge I'm only dl'ing at less then 1Mbps. Even after reboots
