I think I may have posted this in the wrong place first time. Sorry.

Just got a new 2495 and can sync to my PC with no problem except one annoying thing; when I plug into the cradle it knocks the PC offline. I need it to stay online because I use the PPC for a moving map program in my airplane and it has to be updated each month from a web connection.

I have been all over the MS and HP sites with no luck. I basically have troubleshot it down to ActiveSync because when just going from the cable modem to the PC it still fails.

Has anyone seen this or have an idea how to solve it?

Other than that I really love being able to check web mail and change things on the internet from a wireless hotel room. If it will ever run like my PC, that is, almost without problems, then I will be very happy.

Thanks to all the helpers from this site who take the time to help us newbies.

Cheers

Now that's what I like about this site - there's always something new & interesting popping up

I have never heard of this happening before, but I guess that the problem is to do with your A/S connection settings.

On your PC, in the System Tray, right click on the A/S symbol & select 'Connection Settings'; I would expect to see the Serial Cable connection box & USB Connection box ticked, but not the Netwotk & RAS box. Can you confirm what your settings are?

Thanks for the reply. I don't have a system tray that I could find in XPHome but in the connection settings of the A/S opening box only the use USB is checked. The other options are either COM 1 or 2.

I have a router in the system but I have removed it and gone directly from the cable modem to the PC with the same results. As soon as the PDA is inserted into the cradle it drops the PC offline. I have the settings in A/S set to connect upon insertion of the device.

This is driving me nuts. At least I am learning more about networking than I ever thought I would like to know, so I guess some good comes from all the problems.

It would drive me nuts as well!

Sorry, but I can't think what would cause this - you could try deleting A/S & then reinstalling it to see if that cures it.

Otherwise, I'll have a think & see if I can come up with other ideas....

I have tried removing and re installing A/S but to no avail. It syncs good but just causes the PC to drop offline. I think it may be part of the network software from MicroSoft. I cannot believe that I am the only person to have this problem. At least when I solve it I will be in a position to be someone else's hero.

Cheers

Count me as one who also has this problem! I seem to fall off my work network at random...and then have problems reconnecting. I'd be interested in anyone's ideas here.

Stats:
WinXP Pro
AS 3.8
Network servers are Win2003

Thanks!

What happens if you change the connection setting from "on connection" to "manually"? Does your PC go offline when you drop the PDA into the cradle then? If not, does the PC go offline when you synch up manually?

What version of ActiveSynch are you using?

     

I just tried your suggestion and it drops off as soon as it is plugged in with the "connect when plugged in" un-checked. I am using 4.1 A/S.

I just bought Networking for Dummies and I think it is related to my network settings.

Cheers

I am no network expert, but I think you are correct in your belief that the problem is with your network connection.

Windows Mobile 5.0 and ActiveSync 4.1 use the Windows system TCP/IP stack for communication, so the PDA device connection appears as a network interface on your PC. It appears that your PC can only handle one network connection at a time and that the ActiveSync connection takes priority over your internet connection. If your computer is Bluetooth enabled, I bet you can synch up your PDA via Bluetooth with no problem.

I think the problem you are experiencing is either related to Network Connection Managers or to Network Traffic Optimizers. I am quoting liberally from information I found on Microsoft's website:

Network Connection Managers are utilities that allow PCs to handle multiple, consecutive network connections (e.g. Ethernet, Wireless LAN, etc.). In some cases, the utilities will shut down network interfaces and promote other interfaces for the best connection performance. Some of these utilities are implemented as NDIS Intermediate Drivers that monitor and affect the Windows system TCP/IP stack.

Network Traffic Optimizers are utilities that enhance a connection to increase connection throughput. In some cases, this is done by modifying the network packets or re-directing network traffic to save transfer time. Some of these utilities are implemented as Transport Driver Interface Drivers that are installed in the Windows system to monitor the TCP/IP stack.

     

Julie, thanks for taking the time to research this. I had zeroed in on the Network Traffic Optimizer but MicroSoft left it off at the point of "disabling the Network Traffic Optimizer" that is used and see if that had a positive effect. The only problem is, I cannot find out where to look for the NTO and what I am looking for if I do. I am going to do a complete review of the network and see what happens. Mine is simple; I go from the cable modem to the LinkSys wireless router via CAT5 and from router to PC via CAT5 and use a wireless laptop in the other room.

Thanks again to all who responded and/or spent some time on this irritating quirk.

Cheers

I am having the same problem. I installed the Windows Mobile 5.0 on my Dell Axim x50v and installed ActiveSync 4.0 (which I later updated to ActiveSync 4.1 to see if it would solve the problem). As soon as I put the PDA in the cradle my network connection was gone for my PC. I can access the network on my PDA however. If I go to control panel, network connections, local area connection, then select Internet Protocol (TCP/IP), click properties...it tells me that I need to install and enable a network adapter.
My connection won't come back either if I take the PDA out of the cradle.

Please let me know if you have figured out this problem.

Navion,

Did you ever get this worked out? If not, perhaps this will help:

I don't know if this will help but it won't hurt to try it out:

With ActiveSync 4.1, the iPAQ connects as a network adapter in the device manager. Some utilities may mistake the ActiveSync connection as a valid internet connection. To see if this is the case with your PC, open up Control Panel -> Device Manager. Look under Network Adapters to see if it registers as "Windows Mobile-based Device". Then look in the network connections control panel to see if there is a second LAN connection now. If so, double click on it, select the "Properties" button and enable TCPIP.

If you try this out, let me know if it works. I've seen your problem reported on other forums and if this provides a solution it will be really helpful to know.

Julie

     

Hi,
I am also experiencing the same pb. I have a Mio P350 and Activsync 4.1.
What I did is to have 2 connections and i disable one (the PC) when I want to syncronize the PPC. But never found out how to make both work together. If anyone has a solution....
thanks
Tof

You have to insert properly to the cradle. When I had no bluetooth i insertet couple of times wrong, cuase it has to touch to the spciecial thing in the cradle, you have to pre-insert couple of times, sorry if im wrong but thats what happened to me before it wouldn't work and sync, It said couldn't recognize usb , but it works now, unless I insert it wrong, its not easy inerting the ipaq into the cradle, at first use

I have a Dell Axim X51v running WM 5 with ActiveSync 4.5 and have the same problem that Navion describes. Whenever I sync to my laptop the wireless connection to all laptops on the network get disconnected. My one desktop connect by LAN is uneffected. I'm using a Lynksys wireless-G 2.4 router. I checked the things you suggested above and everything is set as above. The only way to get back on the network is for all the computers using wireless to a restart.

My work around is to disable my PC's wireless adapter, synce my PPC, restart my computer and then enable the wireless adapter. If I enable the adapter without doing a restart, all wireless connects drop.

I've only been on one other wireless network other than my own and it was using a router/modem (can't remember the make or model but definitely not a Lynksys) and the connection was NOT affected. Don't know a whole lot about networking, but it sure seems like a conflict somewhere somehow.

The work around is not too bad, but sure would like to resolve this. Any suggestions?
