Activesync Disconnects

[cpetzny]

Hi,

I have been suffering with a persistant Activesync connection problem. It usually connects and syncs fine the first time I boot my machine, but after around five minutes it almost always disconnects (though my Vario II continues to charge). Unplugging and replugging the USB cable does not work and the Activesync icon remains grey. Trying to start the connection manually either from the Vario II or from Activesync on the desktop also does not reconnect the device. In fact the only way to get it to connect again is to reboot my PC.

I'm using Activesync 4.2 downloaded from Microsoft this morning. I've tried deleting and recreating the partnerships, which does not help the issue. I've tried several USB cables which also do not resolve the issue, so I am now asking for your help.

If anyone has any insights into whaty might be happening I would appreciate your help...

Thanks,
Chris

I'm having the same problem, but in my case unplugging the cable from the device and plugging it again usually restarts the sync. Sometimes, however, I have to soft-reset to get it working again. Very annoying.

Hi Chris,

Ive had tons of issues with activesync on my works laptop..... I use a VPN and zonealarm... I used to have tno issues but since I got WM5 wich uses IP address's it always does the same thing as yours.. ive made sure the IP address is allowed in zone alarm.... my colleague also had this issue.. he managed to solve it by using a differnet USB port as his laptop has 3 one is on the side of the machine ... try using a different USB or disable zone alarm if you use it this could be causing the problem.

I sometimes get it to work if I have no VPN client running but as soon as I do use it the active sync stops.

Hope this may help you

I have exactly the same issue with my Vario II, never happened with my Vario and I have changed nothing other than my phone. Makes me think its summin to do with the harware possibly? Anyone else found a cure for this?

I Had the same problems, so I gave up on USB connection with active sync, I have 4 USB ports on my laptop and tried all, I now use bluetooth and works everytime.

There has always been problems with USB and actgive sync, so 4.2 was suppose to fix, but not for me.

I've got the same probelm on my Tytn. I've solve it to delete the Pocket Mechanic :shock: , I've done a S.R. and from now on the A.S. works correctly.

Had to use my old vario for a bit today, used activesync and it worked fine for the whole time I had it plugged in, got a new Vario II replacement today, got home and its exactly the same, would appear to be a mismatch between Vario II and activesync 4.2, can I connect by wifi?

Hello hmm the problem is if it uses direct or ip ,try go settings - connections - ( usb to pc ) and disable advance network funtctionality.

Hope that works

thanks

I had this problem too - I disabled advanced network capabilites in the "USB to PC" control panel under the Settings/Connections folder, and then Activsync stayed connected after that.

Just given that ago, Took me 5 attempts for the usb to pc connection settings screen to show up but then I realised it had to be plugged in to do it! Duh! What features do I loose by disabling ADVANCE NETWORK FUNCTIONALITY?

After the activesync working fine with my orange spv3100 for 4 weeks it suddenly refused to connect. I un-checked the "advanced functionality" box as suggested and it works again. Many thanks for the solution peeps.
I too would like to know what functions this deactivates.

Same problem, I've installed ActiveSync 4.5beta and now it stay connected, sometimes it disconnects but after restart of the phone it works again, one friend told me that the problem comes from the Activesync in the phone, so may be we have to look for the problem in the phone not in the PC

Hi all,

I too started having the same problems with Activesync 4.2 hanging my phone if left charging overnight. I decided to disable the advance network connection and that worked for a while. Now the phone wont sync AT ALL. It charges, but I can't do anything else. I reinstalled the Activesync 4.2, did a soft reset, off-on to the mobile, turn off-on my computer and still nothing. I will d/l Activesync 4.5 beta to see if that solves the problem, but it looks to be a problem with the Activesync in the mobile and not the one in the computer. I did the troubleshooting and it is detecting the USB connection but does not sync. I would really like to know if wireless sync can be achieved. Will post any fix if I find one. BTW my mobile is about a month and a half.

I've read through all the messages in this thread and wondered if someone could help me with some problems i've been having with syncing mine with a laptop. Often when I have the device plugged in when i boot up the laptop activesync won't start until i've disconnected the usb cable then reconnected it again-i never had this problem with the imate jam. My second problem arises when sometimes it says on the files section that there are un resolved items???? i then try to resolve the issue and a wizard comes up with add or remove buttons.afraid that i might remove something essential i tried the add button hoping this might resolve the issue-it didn't. i then gave up as nothing worked. after switching the laptop off and then syncing a day later there were no items to resolve so what exactly is happening. how can there be unresolved items one minute and nothing the next.also i hadn't done anything different on the tytn.if i select the add button on the window does it add a copy of the file highlighted and could this affect the operation of the device.Sorry if this seems a little confusing but i never had this problem with an xda exec or an imate jam.
please could someone help a non technical fifty something.

hi,
where can i find ADVANCE NETWORK FUNCTIONALITY

[Sevenhelmets]

I agree, where is this option?

I'm running version 4.2 and along the top bar all I'm seeing is:

File - View - Tools - Help


Nothing like "Settings" and/or "Connections" in sight. Under "File" there is the "Connection Settings" option, but nowhere does it mention "Advanced Networking Functionality".......


Can someone explain this please?!

[pof]

The "Advanced Networking Functionality" is on your phone, not on desktop's activesync.
On WM5, go to Settings -> Connections -> USB to PC and you will find the "Enable Advanced network functionality" option.

Every time I try that, I just get an error message saying: "Failed to disable RNDIS to use Serial".

Has anyone else seen this message? Happens regardless of whether the Vario II is connected by USB or not...

Thanks,
Chris

[cpetzny]

I'm still getting the RNDIS error, has anyone else come across this? Is there a solution?

Cheers,
Chris

Had exactly the same problem with a previous TyTN that I had but managed to solve it.

1. Uninstalled Activesync
2. Did a soft-reset
3. Re-installed activesync but then tweaked my firewall to accept everything incoming/ outgoing from Activesync
4. Installed a patch from MS, because Internet pass-through was not working

Problem disappeared. Hope that helps

I just got a Dopod 838Pro and was about to turn it in to the seller when I read this thread. After having had similar problems with my JasJar, I thought I new enough to make it work! Tough luck!

Had I read these valuable info before resetting, and hard resetting, and reeinstalling AS over 10 times, I would not have had all the agrevation! Anyway! Disabling the settings -> connections (USB ->PC) on my device, did the trick! The only thing I learned is that in my case just unchecking the USB-PC mark was not enough! I had to HR the device and reinstall AS 4.2! Have not tryied AS 4.5Beta yet!

Thanks

Indeed using BT-AS had resolved my ActiveSyn on/off problem, I am using AS 4.5 beta. It works fine via BT since more then a month now without any issue.

I bought my first Pocket PC HTC HERMES(or TyTN?) 3 days ago and I had this problem of "Failed to Disable RNDIS" from the beginning. I tried to solve it by changing the registery but I couldn't locate the exact registery keys(Wittcomm or etc.) so given up. http://forum.xda-developers.com/images/smilies/mad.gif
:mad:

Lately, I discovered that while I was pairing my device with Pc through bluetooth accidentaly I have created new COM entries. (look in settings-connections->bluetooth->com ports)

After deleting these COM entries as well as my device itself from bluetooth settings, I tried to disable RNDIS and voila! After unchecking advanced USB to PC connection box, now I have my first connection with ActiveSync.http://forum.xda-developers.com/images/smilies/smile.gif
:)

I hope this helps.

Once I had the same error when disonnecting advanced usb and it turned out that my bluetooth gps was causing this, I deleted the com port it was using and voila!

[DdimDdim]

Good time of the day!

I have a slightly different behaviour (no solution yet found). The device (HTC touch cruise) connects, synchronizes, then in about a minute disconnects (charging stops), waits for another minute, connects again, etc.

Disabling "advanced network functionality" doesn't help. Any other ideas or suggestions?
