Its always possible that there is more than one issue here but I my case it is definitely related to location.

For me today's experiences were conclusive.

I set of at my normal time on my normal route to work and left ActiveSync open with my Leo in the cradle as always. Instantly I entered the area I have defined (my 'Hammersmith and Fulham Triangle!! tehe :)) it went from 'Connected' to 'Synchronising' with the spinning icon rotating constantly (I use Exchange by the way).

I tried immediately a couple of other apps - nanoGroove wouldn't connect, Opera wouldn't load BBC Mobile but Internet Explorer would (as usual).

It stayed like this right through the area and BANG the second I left the area, everything connected and I could stream music FAST. All this with 4 bars of 3G or H all the way.

On the way home this evening, I left deliberately an hour earlier to see what would happen - 4pm GMT.

This time the area was as well defined but the drop-out was less severe. It happened as I entered the area and definitely towards the end of the area but I occasionally got some connectivity in between and could stream but it was buffering more slowly.

The problem was definitely still there but not as bad as when I usually drive through an hour or two later (peak rush hour)

The area I have defined starts as I drive close to Earls Court Exhibition Centre and finishes as I drive past Olympia Exhibition Centre.

My journey also takes me very close to Stamford Bridge (Chelsea's stadium for those who didn't know ;) ) and Queens Tennis Club.

I have been to busy technology exhibitions at both EC and Olympia in the past and had loads of problems with connectivity - even when displaying a full signal.

I am also an IT consultant who regularly works with big groups of people using Windows Mobile devices so I often get the opportunity to test theories with up to 30 devices at a time.

One thing I can say is that its impossible to get a consistent internet experience with that many devices in one location. Up to a quarter or more will always have difficulty connecting. They display often very different signal strengths - some on G while another right next to it has 3 bars of 3G.

I have similar problems with GPS fix but I have always put this down to quirky handsets as it seems to be the same ones having issues but this is not the case with connectivity.

Today I was working with school pupils doing GPS activities in the playground using HTC TyTN II's so it is definitely not just restricted to HD2's.

Another thing I have noticed is that with the growth of the iPhone over the last year or so, my internet performance has dramatically degraded and continues to do so.

My theory remains the same - it is to with volumes of traffic on the network, particularly at peak times and my suspicion is that the networks are restricting certain services from certain masts at peak times - otherwise why would I nearly always be able to use Internet Explorer when all other services are dead?

The plot thickens....
[HD2 General] rodrigofd:
Well , taking in account your sayings, we can state that what is currently happening currently in the world regarding wireless internet, is similar to transit networks in some developing cities (like mine, Buenos Aires) : same, fixed size network, with limited capacity, and an explosive increase in high bandwidth 3G users hanged to those networks (the 'cars') ... inevitably, on some circumstances (like rush hours)... there will be traffic jams....and they will be more critical each time, until operators enlarge or acommodate infraestructure.

Issues with hd2's and tmobiles 3g is tmobiles fault

Just a heads up. I have been having issues with my hd2 and 3g on tmobile for the last couple of weeks now. After many talks on the phone with tmobile I finally found two tmobile people that stated the hd2 and 3g issues are because some type of weird permissions issue since march 23rd. I now have no 3g signal since then and they stated that the problem is being fixed but 3g will continue to be down for almost all locations throughout the united states untill at least may 17th. WOW. Weird thing is there is no buzz about this on twitter or no where else but they keep selling the phones and not letting the people still purchasing the phones know this. Thanks Tmobile for giving us the shaft.
[HD2 General] Frameshift:
Doesnt make sense though, since the problem is the same anywhere else in the world. I highly doubt that all providers all over the world have the same 'wrong permissions' set on their network... Not trying to be a ***** or anything, but Im extremely sceptical about all solutions being offered, since Ive tried everything written in this topic, however useless it may seem. The only common denominator is the HTC HD2, everything else differs...

HTC is picking my HD2 up tomorrow for a second time, but I for one certainly aint getting my hopes up for this one...
[HD2 General] cgrec92:
ok follow me here

i live not a half hour from earl's court, i live in piccadilly circus

and someone here also mentioned that they went to a shop in tottenham court road to get their phone replaced because of this problem

all very close to each other, happening to all 3 of us

perhaps a location issue? or perhaps im being superstitious ;)

rodrigoft's bands explanation seems the best to me as of yet

i remember when i was on the phone to t-mobile, and they were suggesting to change which bands

unfortunately i forgot which bands they said to change to but the HD2 simply does not have them, i remember the 850 was fine but they asked for a 2100 and i only had 1900 or visa versa although they didn't seem too concerned by this

so in fact, perhaps it's the antenna in the htc phones which cause this issue, happening in both the HTC HD2 and the HTC DESIRE and the HTC LEGEND and the HTC TYTN.. never had a problem on a nokia or anything..

THEORY

the antennas for most HTC phones do not support the bands which most operators use (definitely in my UK t-mobile case, confirmed by tech support) very likely causing connection dropouts

again the explanation on the previous page explains what the bands do which further proves the point that the dropout depends on location (better when the environment is less 'dense') and the operator (use and support different bands or different locations of towers).
[HD2 General] Frameshift:
Could be, but I had 4 previous HTC phones (Touch Cruise, TYTN2, Diamond, Touch Pro, even 5 if you count the Sony-Ericsson X1, which is made by HTC) and none of them had this problem. Untill a year ago, I was a full-time employee of the phonestore here in The Netherlands (2 years), and I cant recall any HTC-phone being sended out for repairs with this particulair problem.

So if it is the antenna in the phone, it must be a new one, because the phones you mentioned are all brand-new phones from HTC.

But then, whats even more strange is that not all new HTC-phones use the same antenna? How else could we explain that only a small percentage suffers from dataconnectionloss?
[HD2 General] cgrec92:
true, and i am almost certain it is an error that occurs after the G1 (works fine for my brother who has the G1) in fact the G2 had massive amounts of problems regarding this issue, and now other phones such as ours.

only a small percentage suffer based on my previous post, location and service provider.
[HD2 General] Frameshift:
I guess we can forget about solutions then... I'll just keep sending in the phone untill I can get it replaced... How and when I dont know, but as it seems, there is just no solution whatsoever.
[HD2 General] sony7771:
Orange fix It !!!!!

i have the same problem , loses web connections every 5 or 10 minutes,

i call my phone company and the problem was there no in the phone , and they fix it.

so u can try to tell then that u check with other brand phone and have the same problem. so they need to check in their server. it will take like 2 week

until they fix it.

[HD2 General] Sik96teG:
TMO USA isn't changing something in their network on the 17th they are going to be releasing a patch for the device on the 17th that is suppose to fix the random occurrences of data going out.
[HD2 General] rodrigofd:
I hope this info. is real... if that is so, i'll be the first to get such update, unpack it and investigate the real implications, so very likely we can all benefit from it , besides TMO US users....

By the way, i believe the issue we have here, which apparently doesn't apply to the 100% of HD2 users worldwide, triggers with a combination of two factors:

A) Some recent innovation on the HTC technicians: either on hardware (could be new Snapdragon platform? or any of auxiliar chipsets, like the 3G/GSM chip, shared on all failing devices?)... or some drivers/WM OS setting regarding TCP/IP stack, data connection config, .. etc. as we can see that this affects not only to HD2s from various editions (original, Telstra, TMO US, by now), but also other phones (Desire from Cgrec)

PLUS

B) Certain cellular locations (network operator/country + location antenna).

Seems that some of this combinations make a portion of HD2 suffer from this unbearable, deal-breaker issue.
[HD2 General] chrisnash:
Hey, I love my HD2 and have no intention of sending it back until there is a better piece of hardware out there - despite the frustration of the dropouts.

I have reverted back to a slightly earlier rom and honestly the only issue I have now is to do with the time and place I have been.

I have had the same experience today with an old TyTN II.

I am far more interested in producing a useful map of the hot spots that are causing me problems and in seeing if I can identify individual rogue masts, because the area dead connectivity increases as you head further into rush hour.

Be cool to have some nice graphics like a dynamic weather map that shows the 'hot spots' and how they radiate out at different times of the day.

Might start on a Google Map tonight ;)
[HD2 General] cbeenhackker:
It is definitely some sort of Bug on the HD2. I have tried many things now. I downloaded the HD2Tweak tool to set all the data connections to Permanent but still it happens once today.

It looks to be more stable now. The main problem I am having the it is not picking up the data connection. You can see the 3G on your screen but when the wheather should be updating or when receiving Tweets or other things you should see it switching to HSDPA but it WONT...:mad: You will receive a "Server Error" when trying to connect to internet.

It is stuck somehow and cannot make a connection. Only way to resolve it is to turn Off data connection and turn ON data connection in the Comm Manager.

I am using the Stock ROM with every update from HTC on it... also the latest Radio version.....maybe this is the problem?!

I need a permanent solution. I need to know I can rely on receiving mail.:(..etc.
[HD2 General] arienvijn:
If you delete your email account.(s)

is your probem whith your dataconnection gone????:confused:
[HD2 General] cbeenhackker:
I did not try yet...and I rather not..actually :(:( I depend on my email.

I think the more applications polling to internet the better, not?! So the connection will not fall asleep:p. Maybe if I have the guts to try I will do it tomorrow. Maybe someone else can check:D?

From the data connection reset, this afternoon, still working.. Lets see tomorrow morning.

Cya!
[HD2 General] mickfarr:
Happends to me on 3 Ireland. Data turned off and back on fixes it for me too.
[HD2 General] jonnyjay:
Me too. Im on tmobile UK, using dutty Rom....

Why is this not a big issue on forums????

Why only a few affected like this???

hmmmmm...

How boring...
[HD2 General] ronin1973:
I have the exact same bug!

I have to reset my data connection or soft reset my phone at least twice a day ands it's the only thing that really annoys me.

The weird thing is most mornings around 6am I'll receive several emails (various sources), but if I want to update the weather after this, it won't connect to hsdpa and I need to reset my connection again. All works fine for several hours untill it locks up again.

It would appear to be a software bug, not hardware or network related.

(I'm in the Netherlands on the Dutch Vodafone network.)
[HD2 General] arienvijn:
Ik heb dat ook nu eens ff me email uitgezet (gedelete)

Nu blijft hij wel werken ?????
[HD2 General] Ramzidk:
Im having the same problem with all programs that uses data connection, the only thing that helps is to restart the data connection in comm man.
[HD2 General] Dioky:
Have the same problem. First with HTC ROM 1.16, and now with HTC ROM 1.48. Was quick to find out the data switch trick. But that barely is a work around...

On Dutch Vodafone network btw.
[HD2 General] CruSer:
Also

I'm using ROM Touch-IT Black Leo HD2 - v3.1 with radio version Leo_RADIO_15.29.50.07U_2.06.50.04 and the connection problems are driving me crazy! :mad:

Tried a few different roms with different radio's, but the problem is still here.. My provider is KPN... I'm going te email HTC support, because I think it's hardware related.
[HD2 General] firiel:
having the same issues from day one. Did occur using 1.43 (stock) 1.48 (stock) 1.61 and 2.02 based roms.

I also tried 2 different radios the first and the last and still occurs in daily bases. It looks to me, as more of a radio problem

Having to delete my emails wont help me, as my biggest issue is not receiving emails and even worse is not to notice that you have an email. All day I refresh my weather to check if my connection works.

Did anyone brought that issue to htc ?
[HD2 General] Cret:
I've had this happen with at least my HD and HD2, both with Sure. I think it used to happen with my Omnia which was with Sure too.

A reboot cures it every time.

Is it possible that it's just a winmo bug in general?

The thing that annoys me most about this is the fact that when it happens, of course non of your auto updates work.
[HD2 General] imperiallight:
Yes this affects me too.
[HD2 General] firiel:
Nope never occured on any of my other winmo devices and through all version of windows 6.1, 6.5, 6.5.3
[HD2 General] CruSer:
Send support to HTC

waiting for the answer... :confused:
[HD2 General] northernneil:
Happing to me too using O2 stock ROM (about time they did an upgrade!)

ROM: 1.43.206.4

Radio : 2.04.50.22_2

Only had it 2 days and I'm pissed about this!
[HD2 General] Si607:
New (2 days) HD" on Virgin UK. Had to do hard reset five or six times as completely locks up, I noticed it was a couple of times when I was comparing browsers simultaneously, opera and windows on same page, and switching between, but other times just completely at random.

My HD2 software information reads as follows

ROM date 11/18/09 ROM 1.48.405.2 (71294) WWE Protocol Version 15.30.50.07U Radio Version 2.06.51.07

Is htere any point in applying the ROM update on the HTC website, I am not sure if its for people with ROM 1.48.405.2 (71294) WWE or to update to a newer version from it.
[HD2 General] qweac:
Do you guys use push-mail? I just disabled my push-mail (gmail) to see if that solves the problem. Replaced it with non push-gmail.

Nevermind. Did not work...
[HD2 General] Stephen Selby:
This problem, together with other quantum wierdness, has built up after installing successive HTC Hot-fixes. (I have the original ROM and have never installed a new one.)

I have now resorted to a hard re-set and re-installing all my previous applications, minus the hot-fixes. It has cured all wierdness including the loss of the data connection.

[HD2 General] CruSer:
Found a workarround!

Change the existing connection name to internet :confused: and my data connection is stable again.. using KPN Mobile Internet...
[HD2 General] endGameXIII:
you know what...that sounds like what happened with the iphone 3g first came out. remember that? 3g was dropping on every phone, battery life was abysmal, phones were crashing and overheating, etc.

and then they issued a firmware update and everything was "magical" again.

i wonder if htc will be kind enough to do something like that?
[HD2 General] Scrtcwlvl:
The HD2 has been out for almost 9 months now, while it is still their flagship windows mobile device, it is relatively old news to them other than the T-Mobile US variant.

Not sure if we will see any more fixes at this point, other than from T-Mo.
[HD2 General] sstolk:
I've read the whole topic from top to bottom (1,5 hours) and my opinion is that it is the network with several options that the operator restricts.

My theory is this:

My provider T-Mobile caps the connection to what ever my speedcontract is

When I am in a crowded area and I want to download much data like ActiveSync emails and Twitter or submitting a photo to Facebook, T-Mobile is downgrading my connection to let other people also download stuff. To prevent that their data connection is overloaded. This is what a HTC doesnt understand correctly and hangs / locks up.

When I am in a much less crowded place (countryside / woods) the connection never drops!

How I figure? I work nearby the woods not in a crowded place and a T-Mobile Base station nearby. I can even use LogMeIn to connect to home and take over a PC without any problems with my HTC HD2.

When I try this at home to take over a pc during dinner or rushhours.... Bam! Connection drops.

Also I noticed that when I receive a call my band is 3G and when I hang up it's G. After the conversation the connection switch back to 3G within 10 - 20 seconds.

This is my story and can't wait for the solution or the acknowledge to arrive!
[HD2 General] Frameshift:
My HD2 has been picked up by HTC last wednesday, and to my surprise, I got an e-mail on friday from HTC, telling me that my HD2 has had a mainboard-swap. They tested my HD2, and they told me they experienced the same problem, sounds promising that they actualy found something! It will be returned in the coming week. Amazing how fast they were this time.

I will keep you guys posted again, when my HD2 returns...
[HD2 General] Matt7402:
I've been reading a few threads around here and I came across another thread where a member had an interesting thought as to the data issues everyone is expericencing.

It won't let me post the link but its the:

[REF] Official HD2 T9193 (Telstra 850Mhz) Discussion Thread

Page 37 Its the last post on the page. The member mentions that he has AT&T and swapped his sim back to his old AT&T Fuze and then back to his HD2 and didn't have data issues for a few days.

I'm in the process of trying this same theory with my old AT&T Tilt 2. I'll post back when I have something. If this theory proves true do ya'll think it has something to do with what IMEI number is register with your service provider?

If anyone else on another network could give it a shot it might help.

[HD2 General] cgrec92:
as for the sim, i have tried using a different sim on my phone and the problem was still occurring

it is not the IMEI number, i have had 3 different HD2s with different IMEI numbers, i highly doubt all 3 of them were faulty.
[HD2 General] rodrigofd:
Same here....

I might have a workaround, though (i touch wood)..

yesterday i flashed a differnent custom ROM to my T9193...

Used my phone at home, and on the street (car) around the city, and by now 0% drops. Finally i had forgotten what it was to use a nomal working phone....

Try it out and PLEASE drop results here... (after using it for a while)...

[HD2 General] Frameshift:
Well, today I had my HD2 returned. They did a boardswap, so I guess the whole mainboard was switched out...

But, I think u know where this is going......., it didnt work! My HD2 is still dropping connection. I have to say I was sceptical about the geographical theory, but I guess it sounds plausible now. Where I live must contribute to the problem. Dont know what else it might be.

Im gonna phone HTC again tomorrow, lets see what happens...

Edit:

Today I contacted HTC and they told me they were going to escalete the case. Not sure what that means but I hope it does me some good. I will be contacted again in 48hours..
[HD2 General] bjrmd:
I have found a solution that at least works for me (using a telstra HD on ATT usa--have tried at least 10 different cooked roms as well). I found this little app called toggle 3g, http://xdaforums.com/showthread.php?p=3578345.

It quickly toggles the 3G connection, takes about 1-2 sec, and the data connection is fine again. I wrote a mortscript to check the ability to connect to google.com every 5 min and if not there it runs the toggle app.

My suggestion is to first try the app alone, use it when you lose the ability to connect. If it works then you can either just run it as needed or use the mortscript(listed below).

------------------------------------------------------------------------

SleepMessage (2, "Starting", True)

While ( True=1 )

connect("The Internet")

If(InternetConnected("http://google.com/m"))

Sleep 300000

Else

Run( "\Program Files\Toggle3g.exe" )

SleepMessage (2, "Reconnecting", True)

Sleep 300000

EndIf

EndWhile

---------------------------------------------------------------

note the path to the toggle3g.exe needs to be in program files, but you can change the script, or timing if desired.
[HD2 General] Charlie360:
Hi All - I've been following this thread for some time as I've been experiencing very similar issues (I'm UK based with an HD2 with standard world wide ROM - the latest version, using Vodafone UK's network) I don't use my HD2 that much for web surfing however I do use it a lot for receiving and sending email on the move and find it excessively annoying to have to reboot the phone everytime I want to send a message. I initially tried disabling the HSUPA option and this seemed to work for some time until I had to perform a full reset and then this option appears to have made no difference to my drops - I have contacted HTC UK for support, but they don't seem particularly interested/knowledgeable or even helpful - so I'm wondering whether just to give up and buy another iPhone and put this one down to experience - it seems a little defeatist as I loike the phone hardware itself, but this ongoing seemingly intermittent and unsolveable problem is starting to drive me crazy, combined with HTC, showing little or no interest in a solution - I've never tried using cooked or non standard ROMs, partly as I'm a little inexperienced and partly as up until now I've been worried about my warranty, however if I'm going to give up on the phone anyway perhaps the warranty argument no longer stands - has anyone discovered a cooked ROM elsewhere that even improves the situation?
[HD2 General] friend'scatdied:
Same problem. Trying manual operator settings (T9193 on AT&T) now, will report back.

I always get a solid H, but data randomly drops off. The worst part of it is that it doesn't come back for a while, not even with a reboot or a quick airplane mode toggle.

i currently am not in the possession of the HD2 but im very glad this seems to be working for you, i hope i havent jinxed it ;)

please keep us updated with this

can others also try this rom with the same radio and post their findings, if this is in fact the case then it would be much appreciated

about a month ago i PM'ed Chucky to help in fixing this issue, perhaps he has in fact done this, unfortunately i can not try this.

this so far seems to be a plausible solution so please others test

thanks rodrigofd
