Active Sync 4.1 / WLAN trouble

Hi, since I can't locate any bug report form...

Here's my problem. I have a running DSL internet connection with WLAN Router
(Zyxel P-660HW-T7C) provided by Arcor. Usually two Computers are connected to
the Router, plus a PPC (O2 neo, running Win Mobile / CE 5.0). Now, when I
plug in the phone via USB, Active Sync 4.1 starts - and all (!) computers
connected to the WLAN Router immediately loose their connections. None of the
computers can re-connect while the PPC is connected via USB. Only afterwards
reconnection is possible, sometimes requiring resetting the computers. IPs
for WLAN connections are obtained via a static DHCP which is configured in
the Router and which assigns one IP to each of the computers, and - if
connected via WLAN - to the phone. Active Sync assigns an IP of its own to
the phone, which is different from each of the WLAN IPs.

My Operating System is Win XP Pro on each Computer, one has a Network
811.2bg via USB installed, the other one is a Centrino Notebook and has a
built-in intel chip.

Any ideas are highly appreciated, best regards

Hi,
Do you have any special networking software installed such as a VPN, PPPoE
Client, or Firewall on the PCs? What IP address are the PCs using? If
they use the 169.254 address then it could be a conflict.

Further since you are using an Intel 802.11g (probably the Intel 2200BG) you
need to check the version of software you are using. There are known
incompatibilities with version 8 and 10 of the Intel software.

Hi Chris,

no VPN, no PPPoE, just PPPoE passthrough on the router. Windows Firewall is
installed on the PCs, but this should not matter, since I got solid WLAN
connection before _and_ after I plugged in the phone. No need to mention that
Active Sync alone also works fine. The IPs for the PCs are automatically
generated by a static DHCP (MAC -> IP Lookup), they are 192.168.1.x. within
the local net. The adapter in the notebook is indeed a intel 2200BG, and I am
running intel ProSet 10, since honestly, well, version 9 was not working too
good. So this would actually be worth investigating. Is there any way to
avoid these incompatibilities with Active Sync ? Any idea what exactly the
ProSet is doing to spoil the entire WLAN?

Thanks a lot, best regards
- Jens

PS: Just checked at work, connecting to a 811.2b, here everything runs fine
with the very same configuration. So my guess would be that the router is
somehow misconfigured. But I don't know where to start here...

I've dropped a note to the AS team about this. Can you describe any known
differences between the situation where everything works and where it fails?
It wasn't clear to me from your postings whether PPoE was on with the
working system or not, for example.

Hi Paul,
The issue is with the Intel drivers for the 2200 chipset and using WPA
security with 802.11g and the version 10 drivers.

The combination of all of these features with ActiveSync causes the issue.

It causes *all* devices on the network to lose connection in all cases?
I've been in communication with Harish and some of the other guys on the
team about the loss of AS computer connection (the "Activesync Kills
Wireless" thread, here), with WPA/Intel/version 10 drivers, but that doesn't
sound like the same problem as described here, where the entire wireless
network is destroyed when the WM device is connected.

The (almost) same config here:

Intel 2200BG with Version 9.0.4.13 Drivers immediately kills my 802.11g
WPA protected WLAN connection for good the moment my PC obtains an IP
address from the WM5.0 client via AS 4.1 - only a reboot reactivates it.
My notebook is running Win XP SP2 at the current patch level with no
third party firewalls or such nonsense installed.

Other WLAN clients do not notice a thing so it really seems to be a
driver / AS issue...

Yes, it kills *your* connection, but it doesn't prevent others on the same
WPA network from working, does it? Your problem sounds like an *exact
match* for those in the Activesync Kills Wireless thread in this group,
which started a long time back. You can use GoogleGroups to find that
thread and read all the old messages and my attempts to get useful
information to the AS team concerning what hardware/software versions which
trigger the problem. That problem is definitely Intel-specific. You can
see what success a small percentage of people have had in fixing it with
different driver versions in that thread, also.

Yes, that's a nice job of debugging. We have had a *long* thread about
what's going on. Most people who used the 9.x driver got it working, but I
think you've explained why some did not.
