my internet connection keeps hanging. tytn on orange uk

hey,
i have a tytn that doesn't have any orange customisation (for the first time i almost wish it did!).
for some reason my umts/gprs connection seems to hang. it looks like it's still connected but it isn't. sometimes it's just a case of resetting the connection in comm manager and at it's work i have to soft reset!
anyone else suffer this? if so, how did you fix it?
cheers

I'd say everyone suffers from it. The reason it's not reported/discussed/solved is because most people don't require constant data connectivity and therefore never discover the problem.
I just posted about this problem yesterday:
http://forum.xda-developers.com/showthread.php?t=297002
So far it seems to be a problem related to WM itself since it affects different devices.

thanks for the response, but maybe I should make myself clearer.
i've had an spv m500 and m600 and never experienced this.
when I say it hang I don't mean after a significant amount of time. this happens about every 10 minutes! as you can imagine this is incredibly frustrating!

Does it do this if you select gsm only rather than auto?

may be a silly question, but how do I change it?

Start>Settings>Personal>Phone Icon>Band Tab and here you can choose GSM and certain bands only instead of auto.

if you find this does help, then you might want to look at
http://commmgrpro.com/_wsn/page3.html
which is a little app which will switch from band to band from your today screen.

thanks marisa! a neat little app!
anyway, it seems to not hang on gsm. is 3G unstable? or is it my device?

Lots and lots of people seem to have one kind of problem or another with 3G.
I personally think that these devices have problems with switching from one to the other as signals become stronger & weaker, and that's when connections get dropped etc.
I discovered this when trying to use MSN messenger to give me a kind of push email on hotmail. It worked, but only while logged in to messenger, and when the connection dropped, so did the log in!
So, now I'm always connected by gsm, and when I really want to download something quickly etc etc, I switch over to 3g and then back again.
A bit tedious, but at least I know that when I think I'm connected I am!

good answer! it's kinda what i'm thinking now! hell, if the thing is in my pocket should I really care that the d/l speed is whack! like you said I think in future i'll gsm when my device is not in my hands and 3G when i'm browsing!
thanks a lot for the heads up on that app and your advice!

No probs, I've solved most of my issues through this forum, now on the Hermes, and before on the XDA IIi. You'll find it does wonders for your battery life too!

Which Radio ROM for UK T-Mobile MDA Vario II?

Hi all, apologies for posting this, as there I know there's tons of other threads relating to this matter - I've spent quite some time reading (and being confused!) by them, but I can't seem to find a thread which a) has someone describing the exact problem I have, or b) giving a definitive solution. So here it is:
I have a UK MDA Vario II. It's my second one (replaced under warranty), this, and my first one both had a problem where I would seemingly randomly not receive calls or texts. The phone shows it has a signal, and the green light would be flashing to indicate service. However, on occasions, if you try to ring the phone, it diverts straight to voicemail. Sometimes service resumes normally (about an hour later) and I get a message informing me of my missed calls, and sometimes I have to do a soft reset to get it working again.
What I have gathered from reading on these forums is that I may need to upgrade my radio - it had version 1.05.02.00 on it (which it must have been shipped with).
So - following instructions, I put HardSPL 2.10 on to the device, then flashed the Radio ROM to version 1.47.30.10, deciding that this looked the safest bet based on the feedback of other people on the Forum. Having done this (last night) I decided to test the phone once per hour today by just calling it, and I only got to the second test before it failed again - showing signal and green light flashing - but calls going straight to voicemail.
So - I don't want to do any damage to the phone - but I need to know that when someone's calling me, it's going to ring (we're moving house soon, so I'm relying on certain calls from solicitors, bank etc etc). Can anyone tell me of a reliable Radio ROM version for an MDA Vario II on T-Mobile UK? (which won't introduce further problems!)
THANKS!!

Ive never had any problems with calls not connecting, the only times it has failed is due to poor reception and ofcourse network busy errors.
I wouldnt worry about the radio version it sounds like a network issue. Have enabled 3G on it??

I have (and thanks btw - it was your guides that I followed attempting the flash last night). The thing is, a good friend of mine has the same phone, in the same area - and he doesn't get these issues. My other half is also on T-Mobile, but uses a Sony Ericsson and doesn't have any problems with coverage. I'm in a city centre right now, and my house isn't far out - we both have decent reception there.
In fact - an interesting thing just happened (literally..) - I have my phone on a charging cradle, and it had been dormant for a while, so the screen was off. It woke up, as if about to receive a call or text, but then nothing happened... so I called myself from my office phone - and it connected ok.
About 5 minutes later my girlfriend called me up on the mobile, and I mentioned the issue was still there - and she said 'yeah, i tried to call you about 5 minutes ago'.... so it's like the call was received (i.e. the phone new about it), but it didn't complete the process.
I had thought a new radio version might help (from my very limited understanding of such matters) - are you saying that's not the case?
Does 3G affect this too? What can I do - I use the internet more than anything else on my phone....
Thanks

does anyone have any further advice on this?
Mr Vanx? Anyone??

My phone is still randomly losing signal - generally not accepting incoming calls (though today it was not accepting calls, whilst I was still able to make them...). I think I may go and get it replaced by T-Mobile - but I have upgraded the radio to 1.47.30.10, and have put HardSPL 2.10 onto it.
I guess I need to downgrade to original versions, but I can't seem to find a guide which tells me if what I want to do is OK (and how...).
Please - can anyone assist - I believe my original radio rom was 1.05.05.00, and the SPL version was 1.01.

I'm using 1.54.30.10 and it's fine. I found 1.54.00.10 pretty good as well. Much fewer dropped calls comparing to any 1.4x RadioROMs. Signal strenght is also better. The only thing I cannot comment on is the battery life, as I charge the phone every night whether it's 90% or 10%.

did you have the same problems as me? - phone appearing to have a signal but calls being diverted to voicemail... seemingly randomly...

Use GSM mode as default
I have the exact same problem (I travel between Birmingham and London mainly) on my Vario II. It is really fustrating and my wife seems to think I dont answer her calls/txts on purpose(!)
On mine, the problem is due to the 3G mode - when I turn OFF 3G and use normal GSM the problem goes away. I get all calls/txt and internet connections sucessfully. When I turn on 3G the problem comes back - lost calls and unsucessfull internet connections. When in 3G mode sometimes it works somtimes it doesnt
Someone mentioned it could be that it is not switching between 3G and GSM automatically when no 3G is available. However, it happens even when in a good strong 3G area.
I swear this problem did not happen in the early part of my contract but only recently. One theory is that TMobile has sold so many 3G devices now both monthly and pay-as-you-go (esp 3G Data Modems with users using the network for their laptops) that the TMobile cells are just getting overloaded. Also, it could be that TMobile are also doing an upgrade of the 3G network and it is causing problems for users.
So what I do is run the phone in GSM mode as default (so no missed calls/txt and use Opera Mini for quick web surfing works well in GSM mode) Then switch on 3G mode if I am going to do any web surfing for more then 5 mins.
The added side benefit is also much much better battery life in GSM mode (3G soaks up the juice very quickly). I never use video calls ect so no loss there.
My Comm Manager has a toggle for 3G/GSM mode so I use that to quickly change between the 2 modes.
In Summary I would rather have a reliable phone for recieving/making calls then one which is hit and miss.
btw, Im now due an upgrade - wondering if I should stay with TMobile or not...

We appear to have the same phone 'lives'!

Ditto - im due for upgrade in March, and had been looking at the Vario iii - but am now wondering if I should be looking at another network? Is this a consistent problem with all 3G devices on T-Mobile - or does it just affect the Vario ii?

I signed up in Sep 06 and there was no problem with 3G mode then (problem free for the first 12 months at least).
From your phone internet rowser goto http://mini.opera.com/ and click on Download Opera Mini (this is latest version 4).
Before you do this make sure you have Esmertec Jbed midlet manager installed (Opera Mini is a Java App).
I use Opera Mini 90% of the time and its still renders fast on a GSM connection.
Ive uploaded the CABs for you for the Midlet Manager and Comm Manager.
I dont know if it only affects the VarioII maybe others can comment. If its a network issue then I would expect it affecting other devices also.
I want to go for the HTC Touch Dual (aka MDA Touch Plus on TMobile) as my next phone but may go with Orange if it is a network issue. Only reason I stay with TMobile is for the 'unlimited' web'n walk tarrif..but if I can't use 3G realiably then what is the point?

Thanks very much for loading this stuff...
my other half is after the touch plus too - but have advised her to do some research before committing to T-Mob again.... though if she gets it and it's ok, i'll post some feedback on here...
Cheers

The Touch Plus is a good phone if you can live without Wifi...Ive read somewhere that this problem is dependant on the area you are in ...in particular the TMobile cell tower servicing the area you are in and it is possible to phone TMobile tech support to get an engineer to investigate and correct the problem. In my case that would be my home address and my work address - maybe worth a try?

Just to add my 2p worth... my radio is 1.05.05.00 (came on the phone, which was a replacement for the first which had the screen drift)... I've had occasional times when the phone's lit up but nothing's happened, but I usually chalk that down to the phone doing an activesync check for push mail, and as there's nothing there, it goes back to sleep.
To my knowledge, I've not really missed any calls or anything like that since way back last year - when sometimes I'd be sitting in the same café as a mate also on T-Mobile, and we'd do the you-call-me-i-call-you thing to get each others' numbers - and it'd go straight to voicemail! That was quite amusing.
Nobody's told me that they've had problems trying to reach me on my mobile though for a fair while now, so I'd almost completely forgotten about this problem!
edit: yay, 500th post! Took a while but got there eventually... Anybody want to sponsor me with a free Kaiser?

Hi, I confess I haven't read the thread in great deal (am in a rush and am just passing through!) but you could try this official T-Mobile UK ROM. It's Windows Mobile6 and Radio 1.50.xxx (as far as I remember). The main thing is that it's official, and includes their latest sanctioned bootloaders etc. I flashed it to mine before taking back for warranty (as it's not possible to go back to the old 1.05 radio from recent unauthorised versions).
T-Mobile UK WM6 complete MDA Vario II ROM:
http://member.htc.com/ruudownload/t-mobile/TMobileWM6Step1-TMuk.aspx

:O when did that become available? I swore to myself I'd keep an eye on the TM phone downloads site because I knew WM6 was available for some devices, but I completely forgot and since then they've rolled out WM6 for my phone... Which is a proper pain, but at the same time a really nice surprise.

Hard reset your device, install ALL applications on the phone (nothing on the micro SD - except outlook attachments). This should solve the problem.

T-Mobile Shadow - No Wifi Problem

We refurbish and sell HTC phones. Currently we have received about 250 T-Mobile Shadow phones.
Upon initial testing we are finding that some of the phones the wifi does not function. After some reading I see that this is a common problem. Some people have resolved with hard reset, reloading rom, and one by changing some hardware.
We have tried all these steps and still have not gotten any defective ones to work.
Has anyone had this issue and able to resolve it?

I wrote on the wiki some information about it but so far there is no solution.
So far I could "isolate" the problem to the circuit board on the screen part that control the wheel/d-pad and probably the wifi part.
If you use that part from a working wifi phone with the mainboard from a non working wifi phone you can get the wifi to work.
You guys probably can get more info from HTC on that as for me, they simple answer "thanks for contacting us, you need to check with your mobile company or send to repair" but no info

FROM THE WIKI
WiFi Problem:
<LI class="tightenable top bottom">Some versions of this phone are cursed with the "driver is not loaded" error while trying to use the WiFi. <LI class="tightenable top bottom">Some people reported that doing a hard-reset solved their problem.
The cause and solution for this is still unknown.
Software "view" of this problem: On a broken WiFi phone the radio stack wasn't corrupted, all the files and registry seamed to be correct.
Hardware "view" of this problem: Swapping parts between a phone with working WiFi and one with broken WiFi, the problem was isolated to the circuit behind the d-pad wheel where the screen is attached to.
On the working WiFi phone:
<LI class="tightenable top bottom">The writting on the antenna reads: the manufactured date and the word PHOEBUS
The stamp on the microSD slot reads GUKE
On the broken WiFi phone:
<LI class="tightenable top bottom">The writting on the antenna reads: a version code and the word PHOEBUS
The stamp on the microSD slot reads GTIE
Print that out take it to t-mobile and tell them you have a manufacture defective phone and you want a new one.

I tried that and it worked, but my screen quality lost and it was kinna yellowish and at different angle the screen looks different. why?

Have found that sometimes it helps to remove the battery from the phone for 30 seconds or so. After booting, wifi is back to normal.
If that doesnt work, a restart of the router (at least 10 sec without power) also have helped sometimes.
Good luck!

i have tried to remove the battery restarted the router. flashed new radio etc. i run android on it now

Did you try for 30 sec on the battery? and at least 10 sec on the router?

yeah i did pull it out for like 1 min. both the battery and the router. have also tried to find wifi hotspots at friends and at work still not working.
anyone know of a place to buy cheap wifi board to the HTC hd2 ?

what RADIO do you use?

HyperDroid-CM7-v5.3.0[a2sd][CyanogenMod7 LEO 2.3.7][seader_R7] ROM whit RADIO 2.15.50.14

so iam guessing hardware error. i have tryed the red button reset and hardreset whit the volum keys and powerbutton. still not working
EDIT:
i have tryed flashing rom and radio again

This could very well be ROM/Kernel related you would most definitly get a much more specific answer if you were to post in the ROM thread. there is probably more than just you going through this same issue.

in the same vein as the post above, i recommend testing wifi with STOCK WM6.5 to eliminate the (community-made) ROMs (like android, WP7, etc) as possible contributors to the issue.
if you get the same problematic results with the STOCK WM6.5 ROM, then it very likely is a hardware issue. if things are fine with STOCK WM6.5, then do consider a different android build and/or post your findings in the relevant ROM thread so that the chef and users can look into your issue.
if it is a hardware issue, i have read several threads here which seem to indicate that an antenna cable might be loose. a strong indication that this cable is loose is that bluetooth also suffers from a significant drop in range (because wifi and bluetooth share the same antenna). these threads seem to indicate that fixing the cable is somewhat easily possible if you are comfortable with opening the device and fixing it yourself.

A very good advice IMO.
Also it may be a losen contact between wifi/bluetooth module and correspondent antenna: both cases imply to open your hd2..., after this point could be an easy fix!

[Q] Loosing data connection hard

Hi all, this is my first post or thread, i came here cause i heard from ppl this is best site for asking questions about cell phones, i started reading allot this forum and wow did i enter the other world i really like and wanna participate in.
Srry for little intro and lets get back to topic. So i got my first "normal" android and got trouble with it. I am using Samsung galaxy s5 g900F (european) factory unlocked and T-mobile as carrier with 4.4.2 kitkat. I have a big problem with a data connection that keeps going off every 30sec to 5 min if i use option to search and auttoconnect on LTE/WCDMA/GSM option. I read forum but no1 is mentioning this model as problematic 1 so now i post thread about.
Does any1 know what could be problem and how to solve it. Sometimes my data connection comes back and sometimes it doesnt and i have to switch type of network to get back again online. All other options that don't include LTE auttoconnect work just fine, i tried to get another SIM from carrier but same problem, i tried to get another Phone since i work in hardware firm and still same problem on another device, both were same models.
I still didn't put any ROMs but i really consider doing it maybe l8r on, it is stock version.
Pls be genttle since this is first time i post, maybe i did it on wrong place but i did read rules and everything and i think i did it on right place.
Ty in advance.

I did have a slightly similar problem years ago - when in roaming my phone could not connect to anything. What helped was a change of simcard for a new model - after that all was good.
Since you did try your SIM on a different phone (same 900F?) I would advise you to try: first on a completely different brand and phone model - if you can.
If this does not solve your problem do shake your service provider a bit - they could have supplied you with two faulty SIM cards in a row - that can happen. Otherwise - maybe there is a stupid limitation in your service plan which is causing this. There is no - to my knowledge - ready answer to the problem you have described.
Best of luck and if you do solve it come back and post - it will be very useful to lots of people for sure
Cheers!

Too many variables. You haven't observed enough of a pattern yet or tried enough things to narrow it down a bit. It could just as easily be carrier side issues as a bug in the firmware not negotiating a new connection if the LTE signal is lost.
A number of people were having data disconnect issues and that was addressed in the 4.4.3 /4.4.4 update. So that is one option to consider. And you could open a support ticket with your carrier. That is hit and miss as to results, but sometimes tickets actually resolve issues.
There are also a number of apps that may mitigate or possibly even solve your issue. Have a look at 4G LTE Switch and LTE Discovery.

Will try it today. Thanks for the help. Really appreciate it.

I did have a slightly similar problem years ago - when in roaming my phone could not connect to anything. What helped was a change of simcard for a new model - after that all was good.
Since you did try your SIM on a different phone (same 900F?) I would advise you to try: first on a completely different brand and phone model - if you can.
