Very bad T Mobile UK data performance with current radio

All,
There seems to be an incompatability between the "current" G1 Radio ROM (62.50S.20.17H_2.22.19.26I) and T Mobile UK's network.
Even though this is the ROM they are rolling out to G1 users via OTA updates!
There are a number of issues including data connections that freeze and never re-connect without a phone reboot, incorrectly sticking to GSM in areas of good UMTS coverage, random disconnections from the data service, and a strange problem with the first SYN packet in most/all TCP sessions going "missing".
Combined with the ever-present problems with their packet shaping and web proxies and it's pretty grim.
TM UK are certainly aware of the problems unofficially - most of their (very good) UK-based support team tell people to lock their phones to GSM only, which does help a lot but is quite frustrating.
Anyone know whether there's a new radio coming that fixes this? Or a TM UK network fix? Or a better work-around?
Cheers

I am using an unlocked g1 on 3 in the UK and I am experiencing the same problems.
I was going to try downgrading the radio if possible but not tried it yet.....

I personally don't recomend a radio downgrade, especially if you have haykuro's spl. Instant brick

The previous radio doesn't work with cupcake.

I do have some speed issues in certain areas but I've not had any frozen connections that I couldn't fix by restarting the browser.. I actually assumed it was an issue with the hero browser, not the network.
I doubt there will be a radio update just for UK users. We are insignificant. As a Briton, you should know this by now.

I live in Carlisle, Cumbria and I have no problems with either 3G or GSM. Well, apart from the obvious lack of connectivity in Lake District
You can see my specs in the signature.

I am also a UK user, Im running a rooted phone with exactly the same setup as Karolis. Im not experiencing any issues either.

So if it's not the radio, it means that you either have hardware problems, or T-Mobile's coverage sucks in your area.

It is some sort of issue between the radio and TM UK- it was quite widely reported as being an issue when the Cupcake update was first rolled out, but things then went quiet. It could perhaps be regional, but it certainly isn't related to signal strength.
I'm aware of multiple people with the same issue .

Well, I guess some of us just got lucky while others not so much.
Did you try going to / calling T-Mobile?

Officially there is no problem - but they suggest you lock your G1 to GSM.

[Q] *Is anyone having problems w/ 4G and flash sites?*

Peace All,
Has anyone been having problems w/ their 4G service wherein it hangs (on loading) a site that is heavily ladened w/ FLASH (not to be confused w/ the current Gtalk and market issues)? I've tried the plug-in selections of "ON DEMAND" and even "ALWAYS" and it seems that it takes my 4G almost 3 -4 minutes (if it even loads) just to download the site fully---my 3G is actually faster . I've ran speed tests and when i'm on 4G i"m pulling 4.63 mbps down and about 1.00 mbps up---I've even checked to see if my RSA keys were intact and they were. The people (customer service) seem oblivious to this problem. Is there a fix for this?
thanks in advance for anyone's insight to this problem

I don't know, I'll check mine tomorrow when I'm in a 4g area.
Problem with customer service is, they don't have a clue with anything network related. All they do is check to see how many problems similar to what a person reports as a problem and then make a note of it.

No problems with flash on 4g.
FYI - I am running AVO v9 and Flash Fix 10 so I can watch Hulu, and it worked great.

Peace,
Well i guess I'm the only one---this has happened on every ROM I've tried (Ava9 and Myn's Rsl2)---I've called Sprint and I've ran various tests to check my 4G and my RSA keys are in tact and my MAC address is cool---I also have the latest radio, prl, pri and wimax versions---I'm going back to stock---theming and custom ROM's are too much of a hassle and not worth it (most people on here appear to be sooo OBSESSED about battery life that they turn off every function of the phone so that they can brag that they havent charged in 8 days ). I use my phone to the fullest and like running 4G--since im in a 4G saturated area---all day
Thanks anyway,

use flash on demand, that speeds up all your site loadings, make the browser more stable, and removes ads, unless you like ads, .

For me flash site works perfect on 4G...

only issues i have on 4g are pc related, whether im tethered or using hotspot, if the 4g dips just a little the flash video stops loading, when i get to that part the players just hang at what ever the buffer says which is usually 45% to 51% and i have to refresh and jump to the place it stopped, the overall 4g connection is very stable, i have no clue whats going on
btw would you happen to be using dolphin browser hd?? there have been a lot of comments about browser slowdown with froyo and the site has a few suggestions to help speed it up

I've actually got the exact same problem as the OP. I recently did some modifications to the wimax settings so 4g would connect faster and stay connected longer and wonder if that may have something to do with it. Otherwise I do not know what might have changed.

[Q] flakey network

Hi,
I'm on my 2nd tab now (1st had a battery fault). Both have exhibited the same issue, so I'm pretty sure its firmware or some other influence. I've seen the problem with both 3G and Wifi, so I'm guessing its the network stack.
When connected to the internet or in the app store I get network errors, the most common is "Web page not available". Clicking retry a few times will often resolve the load. Rebooting the tab will correct the issue (its also snapper at loading pages after the reboot).
Anyone else seen this issue?
Cheers
Jim

I'm not sure I've had the problem with networking issues you describe but I can confirm the battery issue is legitimate having owned Sprint, VZW, and now the T-Mobile version of the tab. The are all extremely slow to charge, and also discharges (or at least it says it is) to 99% even when plugged in.

[Q] Connection issues

Ok so I have been searching for an answer to my issue for a few days but have had no luck. My wife and I both have an evo that we got at the same time. I rooted both using the same method and and we both have the cm7 Tom with the kernel it comes with.
For the past week she has been having connection issues. Sometimes when accessing the android market it says network connection error and other times it works fine. When accessing the internet it will sometimes not load the page and say that the site may be down. The has been happening a lot to her lately. When these things happen I try the same sites on my phone and they work fine. This is all done over a 3g connection. I have tried resetting the phone to factory and then redoing the rom and nothing helps.
Any suggestions?

I'm having the same issues as well. I've flashed a few different roms and my radios are up to date.

I had similar issues and found that by tweaking the Pri, Prl, and radio...can be found in dev section, that I was able to overcome... could just be a bad combo with that rom

VyperVainz, do you mind sharing what worked for you? I'm running synergy with the latest pri, nv and radio.

I think this is a network issue. My wife and I have been having both data and texting issues. She has a blackberry so not Evo isolated.

Sprint's network has been pretty crappy lately. Slow speeds dropped loading pages, I don't think it's a rom issue

It's an internet, non phone issue. :-D I often go betwen wifi and the normal connection to get a connection to the market.

3G Problems

Hey all.
Iv been following xda for awhile now... im loving my SG2 but I have some trouble with my 3G.... I use it to tether to my laptop and noticed browsing speeds etc will be fast then go really slow then fast again as if it looses the signal... even browsing and using anything to do with the net, even downloaded apps... it will download fast then suddenly slow down and speed up again... and sometimes I cant download apps at all because it doesn't even start...
BTW: Im on LeoMar75 2.6 XXKH3 and on Optus Network, I have tried other versions of LeoMar, MIUI, CM7 and others...
Can someone assist me, maybe have seen this problem else where.
