Launching activesync cripples wi-fi on laptop

[watersigndj]

Using
ActiveSync 4.5
Win Xp sp2
xv6700 Kirvins aku 3.5

just as i connect the usb cable to xv6700 and activesync starts, the wi-fi conn on the laptop disconnects and further cripples the wi-fi router at my place rendering it unusable even by the desktop. the issue only resolves once the device is removed and the laptop is restarted...

SOS out to anyone who can help me resolve this...

have you tried to enable or have enabled tethering with your PPC? I am asking since WinXP has the ability to use your PPC device as a usb modem, and since WinXP may be detecting your PPC as a modem, then it maybe disconnecting your WiFi as it is seeing a better connection device, aka modem. I would make sure that the WModem.exe file is not trying to run on the PPC device.

I had this problem as well, but with a Treo 700wx on a different laptop than mine. When the Treo was connected it did exactly what you described and all devices on the network became unusable. In my case I had WPA turned on for the wireless connection, and I read this appears to cause the problem.
The two ways around the problem is to use a wired Ethernet connection or in my case I had WPA and completely turned encryption off and this solved the problem as well. You might even try just going to WEP.

It's such a weird problem, because I have an almost identical HP notebook running the same version of Activesync 4.5 and have no problems. I even downgraded the problem system to 4.1, but still had the same issue.

Good luck.

I have had similar symptoms (loss of wireless connection when plugging in 6700 to laptop) and have always attributed it to MS's decision to cripple activesync over wifi, starting with the 4x releases. The windows mobile team blog has a security-related explanation. Mseigle's experience seems to prove me wrong.

Nah it only affects Centrino laptops (i.e. have Intel Pro wifi adapters) that are connected to WiFi networks running with WPA security. It is a problem in Intel's drivers and to my knowledge it is still not fixed.

The workarounds are (pick one):

1. Use WEP instead of WPA on your wireless access point
2. Use a different brand of WiFi card
3. On your PPC go to Start->Settings->Connections tab->PC to USB icon and uncheck the "Use Advanced Networking" box. This is the method I use--it reverts the activesync mode to the old serial-based way instead of the new RNDIS method.
