Frequent 3g connectivity on/off on vista side

[danielherrero]

Hi.
Anyone with same problem. I only have seen it on vista side. Working with 3g conectivity. One minute is connected with tray icon showing globe. Then 30 isnt connected with tray icon showing computers with red cross. Then again connected 3 minutes. It seems a problem between vista side and internet sharing service from snapvue. I ve seen this issue in other spanish shift. Maybe a spanish version problem? any idea?
Thanks

[gavmiller]

Not much help I know but see my thread titled 'continued vista connection problems'. Have you been using internet sharing to gain access to WM 6.0? i noticed Activesync was always starting on the snapvue side which I think is linked to the constant disconnections.

A full restore from the restore partition solved my problem and I now get a steady 3g connection.

[danielherrero]

Thanks for your response. Not alone now. Format is a solution but we should know the origin of this problem. Obviosly is related with the way connects to 3g, this is, using Internet Shared connection with snapvue...but...why suddenly activesync (client or server part) tries to connect the other side and breaks the internet shared connection? any idea?Did you install sp1? is your shift language english or other one? ( I am trying to discard sources of the problem).

pd. While I write these lines on winmo side I can listen vista side sounds (connect/disconnect each minute...)

[danielherrero]

Hi,
I did some changes and It seems (by now) the problem is solved. I ve playing with continous 3g connections. This is what I did (I dont know which one did the trick).
1) Disable activesync usb connections for both sides( I did it for vista side days ago but know I did too in snapvue size.
2) Sevice Sync bluetooth Server stopped and set manually.
3) Reset both sides

Now I ve a stable 3g connection....

Glad you got it working. What do you do to disable Activesync on the Snapvue side?

I only noticed this problem after installing SP1 but I was working mostly with WIFI so cannot be sure there is a link.

Hi.
The problem is solved, now for sure. Open Activesync in winmo,then menu/connections and uncheck "use usb ...". I removed too the partership between both sides althought It isnt important, I think...

[gavmiller]

Thanks Daniel. Good to know incase it happens again.

[danielherrero]

Today I am having the same issue...mmm, I dont know what else I can do. I will post the events I can see in the event's viewer....

Hi Daniel - are you still having these problmes?

[danielherrero]

Hi. I didnt have that issue anymore. I removed the partership whith the device on vista side. I remove "Usb connection option" on activesync in both sides. I uninstalled "Remove NDIS Share connection" (Device Manager) on vista side and rebooted. Then on restart vista recognized again the device(Remove NDIS Shared connection) after some minutes(5-10 min) and then all worked correctly. I think the last step did the trick. But I am not free of problems. Like I told before when I resume the device and It was hibernated/suspended for a long time (several hours) the 20% of times It cant connect 3g and even I cant restart vista but keeping pressed the power button. So, by now, If my device is going to stay suspended for a long time (night) then I turn it off......

pd. When I need connect vista and snapvue I turn the phone off. I enable usb connection in both sides and use usbtools. After using the connection I undo these steps and all works correctly by now (last 3 weeks).
Ensure too that Vista hasnt setup a new Windows CE device on Device Manager. To check it open Device Manager, then "See devices by connection" and check each usb connection. If you see any Windows CE device disable it. I think both Remove NDIS Shared connection and a Windows CE Device was fighting for the same usb connection (In my case)

OK, the only bit I hadnt tried was the uninstall of the NDIS in device manager. I'll give it a go and see what happens. Thanks again for this reply!

[schijns]

Thanks Daniel for your detailed description on this problem, which I also have. Interesting thing is that for me it only occurs when I am on the move with my Shift. No problems when my Shift remains on my desk (like others described in this thread: http://forum.xda-developers.com/showthread.php?t=381220&page=2 )

On your described solution: I removed the Vista/Snapvue partnership and the usb connection on both sides. But I am not able to do the next step: "Remove NDIS Share connection" in device manager, because it's not there (see attached screenshot). Does this mean it was never there, so I do not have to uninstall it? Or is there a different way to find it?

[danielherrero]

Hi.
Reset Vista to ensure It boots correctly. Then wait to be 3g connected. Once you are connected the device "Remote NDIS shared connection" should be there under network cards. Then uninstall it and reset again. Once booted you have to wait several minutes until vista detects it again and installs drivers.....

pd. And try to contact HTC. Maybe (only maybe) if HTC is reported with same problem from many people they releases a fix.....

Hi there,

That did not help at all!
Waste of time.
But thanks for the hint.

What DID help for me was closing WMDC through taskmanager.
When you just exit WMDC, task manager still shows that it is running there in the background and apperantly scanning your ports for mobile devices ore something.
I stopped it from running and have a stable connection now.

Hi

Do you have to do this each time you start vista?

Cheers

I think you only have to do it after you used WMDC. On my shift it doesnot start at boot (not anymore...) If I want to sync shift or my kaiser, I need to startup WMDC manualy.

My experiences so far.
Is it possible that it is the energy plan that is responsible for the loss of connection. I installed SP1, no problems it seemed. Today I wanted to use the 3G connection with the battery (balanced energy plan). And then it started to disconnect and to connect in small intervals. I did the routine Daniel described: uninstalled NDIS driver. Reinstalled it but connectivity problems remained.
Is it something to do with the battery powered system?
Because, as soon as stop using the battery, plugging in the power adapter again everything seems to be okay. I am not sure about it, but I think, when I use the max power option with the battery the connection stays and fails when I use the balanced energy plan.
So can it be that something in the energy plan is responsible for the loss of the connection?

Experts, does that make any sense?

I will give it some more tries.

S.

[Pfeffa-rah]

I had the High Performance powerplan on all the time......

[abp]

Hi

This is a problem when sp1 is installed and you are using 3g in vista being in balanced or power save power plan. it has nothing to do with activesync and usb ports (i have never had a connection)

i called htc yesterday, they clamed they had never heard about it before, so please as many as possible call htc and tell them then maybe just maybe they would release a fix

in rhe meantime i uninstalled sp1 and everything works

[Settembrini]

In my case the solution is quite clear.
3G works in Balanced mode and in High Performance when power is plugged in. I am not so sure if it works in “Power Save” even when on power.

3G does not work when either on “Balanced” or “Power Save” when using the battery. Battery works in “High Performance” even when all the options are set like they are in “Balanced” mode.

This I found somewhere else in the forum. It is from Daniel and I guess he says the same, more of less.

Well. I ve been doing many tests and changes and I thing the sd, suspend crashes and 3g closed connections are gone.
I use equilibrated energy plan but I hadn’t any issue when ac connected so I ve modified this plan to make equivalent the behavior when not ac connected, but not success. The problems are still there. Its incredible because the configuration for ac connected/disconnected is the same I ve modified all the parameters (usb, expressPCI, , etc)
So I ve set High performance plan and I ve modified it a little bit, only screen brightness when no ac connected and now all works correctly. I start the system (no ac connected). Then I suspend / wake, hibernate/resume the system several times being ac no connected and the problems are gone. 3g connection is very stable. No crashes from standby to hibernate state. No sd missing problem. So by now I will keep in this "High Performance" modified state
pd. So It seems that a plan is compounded by customizable parameters by the user and hidden parameters)

Now, those who have not installed SP1. Is this really no issue for you? Or have you always been on power or always used “High Performance”?

Well, even when I plug in my external battery and the green light indicates that the machine has been plugged to power, even then it only works in “high performance” and not in the two other modes.

Very strange!

This would seem to confirm some of the strange behaviour people have reported when 'on the desk' compared to 'moving it around' The thing that connects these two would be that when 'on the desk' they probably had the shift plugged in. This was certainly the case for me - I knew it sounded implausible at the time but of course it was linked to the external power, not just that the unit 'was being moved around'!!

I'm almost tempted to reinstall SP1 and try it on max power plan. Mmmmmmm Anyone else tried this solution yet?

[danielherrero]

I never had that problem since I changed the power plan (one month ago)
Dani

[firedup]

OK, had some time on my hands this morning and reinstalled SP1. Installation was fine. Problem occurred as soon as I unplugged the external power supply. I chnaged to high performance power plan (turned down the brightness a bit!) and hey presto! All seems to be OK. Not sure what battery life I'll get but fingers crossed this has sorted it!:):):D

[Flanimal]

I can confirm that after installing SP1 a second time (rolled back after the first time due to the connectivity problem), HD connection is working great now with SP1 when power cable is connected, or high performance is selected when running from the battery.

Whilst running from the battery on balanced, HD connections tends to keep dropping off.

Ramping the power back up to high performance and switching the modem OFF then ON gets me back a relieable connection.

I've only had half a day usage since reinstalling SP1, but so far my observations have been 100% in line with your hypothesis.

Thanks for working this one out. Now I'm hoping for a solution so that I have my longer battery life back.

[Settembrini]

Hi,

as I said before, when you have to use the battery and switch to "High Performance" you can change all the settings to "balanced" mode and it still works.

3G + power adapter = all modes work.
3G + battery = high performance only works, but you can use the settings of "balanced".

I would assume that if you go to the 'advanced settings' of the power plan though that there is a setting in there which if changed would prevent it from working. Sure, you can reduce backlight and timeouts etc but it must be one of the other advaced settings to do with processor etc that causes the issue.

[stormforger]

I read an article over at pocketables.net about benchmarks being higher on the shift using balanced vs high performance. I know it sounds crazy but I drank the cool aid and everything seemed fine but was at home on WLAN for couple of days after that. Now I am on travel for a couple of days and my 3G has been failing with all same issues listed in this thread. The switch back to high performance settings was a instant fix! It has been stable for the last 2 hours.

:) BIG HUGE THANKS to all of you for figuring this out and posting your findings. :D

Hi Folks,

I have the same issue: 3g unstable. Tried all of those uninstall, uncheck, reboot whatever tricks. None of them worked.

The only thing that always helps: use the high-performance setting.

I reconfigured the brightness etc., no problem.


Wrote 2 emails to HTC, no response.

Cheers, Hyrex

[Settembrini]

Hi,

I have already written 3 emails. No response.

I sent 2 mails and called them....They will be busy with htc diamond looking for new customers and leaving alone the old ones...

[StefanoR]

I've been having this issue only for the past few days. SP1 was installed two weeks ago, and ever since the only way to get the 3G modem to connect was by resetting SnapVue from ShagCtrl. After that I could get a stable connection even for hours (I actually survived a one-day LAN outage in my office thanks to the Shift!).

Now I've just tried the "high performance" setting, but I don't have too much time to fiddle around today. I'll see if this works for me as well over the weekend. Anyway, thanks for the tip! :cool:

Indeed you are correct. I have now created two new power plans based on High Performance, one with the settings of balanced and the other with the settings of power saver, and both have proven to have solid SIM connection whilst running from battery.
I am very happy. Thanks for this top information!

Hi all!


Here's yet another victim of the 3G problem. I got my Shift about a week ago and started having problems after 2 days of operation. What seems to be different than with most others, I needed to log off or restart in order to regain 3G. Hitting F5 (reload) or just waiting didn't help at all. Sometimes switching to WM and updating the weather did the trick.

Now I've reinstalled Vista with NO updates at all. Using High Performance, disabled HSPDA (which isn't available in my town anyway), disabled PIN code enquiry, and enabled roaming. SnapVUE is unliberated.

So far about 4 hours of uninterrupted 3G operation, with and without the power cord attached. I left the Shift home for the day dispaying a web page that reloads every 5 minutes. When I get back home, I really hope to see a working 3G connection...

[EeroA]

When I get back home, I really hope to see a working 3G connection...

... and I did! The connection had stayed on all day (or so I presume because it never recovers by itself when it drops). During the evening I used it for maybe 3 hours and it only disconnected once. although it happened when the battery was almost drained, I believe it was the networks fault this time.
