I have been trying to send a hard disk image file across my wireless
network from my Win98SE machine to an XP Home machine for storage, via
ethernet cable to a WAP wireless enabled router, then wireless to the XP
machine.
About 7 or 8 minutes into the transfer I get an error message on the
sending Win98SE machine saying that the network has become "unavailable"
and the transfer stops/fails.
I have tried turning off the screen savers and power saving on both
machines but still encounter this.
The wireless adapter on the receiving machine has power saving DISabled.

Small file transfers work fine and the wireless network seems otherwise
stable.

Incidentally every time I switch users on the XP machine the wireless
connection goes down and then comes back up again.

Is there anything else I should be checking - I'd like to be able to do
these large file transfers if possible.

Many thanks.

Try selecting a different channel (frequency) on the wireless router
in case something is interfering with the signal. The xp machine will
automatically detect the frequency change so you only need to
reconfigure the router.

I am not seeing any instability on the wireless network over lengthy
periods EXCEPT when I do an unattended large file transfer - I am
inclined not to think that there is any instability in the actual
wireless link itself.
If I keep pounding away on the kb this network link is solid.

I'm now trying this the "other way round" - while sitting at the XP
machine (the one with the wireless connection to the router) I am
copying from a shared folder on the Win98SE machine, to a shared folder
on the XP machine, and keeping the XP machine awake by using keyboard
etc. The win98SE machine is unattended and has all Windows power saving
including screen saver disabled, including power saving disabled for the
ethernet adapter.

So far so good. I've copied one 300Mb image file and am copying the
second 700Mb one at present.

Next I will try the same exercise leaving the XP unattended and see what
happens. It should stay awake as there will be disk acitivity via the
IDE controllers which are enabled (in Setup/BIOS) to reset the suspend
timers.
If that works, then I will have found that things work with XP wireless
copying from Win98SE wired, but not with Win98SE wired, pasting into to
WinXP wireless.
