Before doing all that again, there is one comment I'd like to mention. Re:
the behaviour of the wifi connection. I have been referred to this
http://www.microsoft.com/windowsxp/u...02april22.mspx .
do you not think that the comments in here may be pointing to something on
my system that may have been contibuting to all the conflicting results I
have been getting. ie. the bridge may not work with a nonipromiscuous mode
network adapter (my wifi dongle)? What are your thoughts about following
the advice given to set the wireless adapter to 'ForceCompatibilityMode?

To try and clarify a potted history so far.
Yes my router's dchp server is on as the following addresses were assigned
by it when I had the XP Desktop, W98 Desktop and XP netbook (at one stage)
connected to it by straight ethernet leads.
2wire 2700HGV 192.168.1.254
XP Desktop 192.168.1.64
W98 Desktop 192.168.1.65
XP netbook 192.168.1.67

When I added the wifi dongle to the XP Desktop it was assigned 192.168.1.66
and the
XPnetbook on wifi was assigned 192.168.1.68

When I later moved the 2wire 2700HGV downstairs to be sited next to the main
'phone socket and connected the two desktops together with a crossover
ethernet lead, the W98 Deskytop was assigned 192.168.0.147 and the
'gateway' (presumably the ethernet adapter on the XPDesktop) was assigned
192.168.0.1. With that arrangement both desktops were communicating with
each other and would both connect to the Internet as long as the Internet
Zone security on their installed ZA firewalls was set to Medium. The
XPDesktop and XPnetbook would also communicate with each other - through
wifi, but XPnetbook and W98Desktop would not. What I am ultimately trying
to achieve is all three computers communicating with each other. Since
trying to do this by using a network bridge on the XPDesktop then the
problem with the wifi connection from XPDesktop to 2wire 2700HGV only
functioning if the network adapter is disabled or W98Desktop switched off
has appeared.

Follow up.
Looks like I'm there, but not exactly what you advised. After setting all
pcs to receive an ip address automatically then setting up the bridge on the
XPDesktop, the assigned addresses were, netbook(wifi) 192.168.1.68,
XPDesktop (wifi) 192.168.1.66, W98 192.168.0.147 and gateway (presumably
XPDesktop's ethernet adapter) 192.168.0.1 . The W98Desktop could still not
communicate to either other computer. I thought if I rebooted both desktops
then perhaps some helpful reconfiguration would help. I made sure that the
XPDesktop and it's wifi adapter were fully operational before booting up the
W98Desktop. During this boot up I got the error message "The following
error has occurred while loading protocol number 0. Error 59. A network
error has occurred" Clicking on the OK button got me through to the login
page etc. When I checked ipconfig all addresses were 0.0.0.0. I then
manually set up the ip address from the W98Desktop giving it the address
192.168.1.200 and assigning the router address (192.168.1.254) as gateway.
This has worked and I not have Internet access on all m/cs and data can be
transferred between them all. So I think I will now leave well alone. Many
thanks for all your help. Hopefully next time I boot up nothing will have
changed.

I don't know if this is your problem or not but I do know from
feedback that windows bridging is quite temperamental and doesn't
always work as anticipated. For anyone in this predicament the
alternative routing option is the way to go. I did post some details
of this earlier in the thread and that is what I'd advise you to do.
It appears complicated at first glance but it isn't. The only thing
which might be new to you is setting up a static route in your router
and maybe editing the registry.

That's an address assigned by the xp desktop running with ics enabled.

That's the ics server address which xindows gives itself when ics is
enabled. It can't be changed to another address.

The win98 would be able to access the XPnetbook but it's impossible
the other way round.

If you have two network adaptors on the same subnet (which you do
currently on the xp desktop) then windows will always use the wired
adaptor in preference to the wireless unless you manually change the
metric settings in the tcp/ip properties. Disabling the wired adaptor
(or switching off the connected win98 box) would then cause the
wireless adaptor to work. This is what you're seeing.

Your best bet as I said earlier is routing. Here's how to set up your
computers AFTER disabling ics

2wire dsl gateway at 192.168.1.254

set a static route to send traffic for subnet 192.168.5.0 to go via
192.168.1.2


xpdesktop_wireless

static ip address 192.168.1.2 mask 255.255.255.0
default gateway 192.168.1.254
dns server 192.168.1.254 or your isp's nameserver address


xpdesktop_wired

static ip address 192.168.5.1 mask 255.255.255.0
default gateway leave blank


98desktop_wired

static ip address 192.168.5.2 mask 255.255.255.0
default gateway 192.168.5.1
dns server 192.168.1.254 or your isp's nameserver address


You also need to edit the xpdesktop registry to enable routing between
the wired and wireless interfaces as follows

System Key:
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\Tcpip\Parameters]
Value Name: IPEnableRouter
Data Type: REG_DWORD (DWORD Value)
Value Data: (0 = disabled, 1 = enabled)

Hopefully.

I suppose if it ain't broke don't fix it.

I posted some further instructions which crossed with your post. Keep
note of it for future reference in case you need it,


Jim.
