Toshiba E740 PDA wifi problems

G'day all.
I have re-posted this plea for help into this topic, sorry if you are reading it again.
I have searched high and low for an answer to my PDA's problems.
My E740 inbuilt wirless unit will not stay on when switched on with either the hardware switch or via the software version at the top of the screen. I have installed the latest driver I can find, I've soft reset, hard reset, re-flashed the rom you name it.
HELP!!!
I have removed the CF card and done all the above again, and it works for a while (coincidentally long enough for me to find a local BORGWIFI node) then next time I try to use it, it switches on for a second or two then off and stays off. I'm sure it's not a hardware problem because it will work no problems after a full reset, until the pda is turned off for a while.
Any ideas at all would be very much appreciated.
Thanks

Is it covered by warranty and have you approached Toshiba or a Toshiba authorised reseller/service agent (such as ComputerLand) about it? You dont mention if you've googled this either...

Thanks for the reply.
No it's no longer under warranty. I've contacted Toshiba, and was reffered to?? can't remeber who, here in Auckland, gave them a call and was told they would only be able to send it to Toshiba, to get the switch replaced. Didn't fill me with huge amounts of confidence, so I haven't sent it yet. I'm not really in a position to spend heaps on repairs. The pda side of things is fine, so I may look at a cf wifi card if I can't get it sorted.
I have searched everywhere on the net for a solution, so far I haven't even found anyone with the same problem, some similar but usually related to leaving a memory card in all the time. I was doing that, have since removed it, rebooted, reflashed etc.etc.etc.

Cheers

This guy had a similar problem and fixed it by removing and then reinstalling all his software. Here he discusses the PDA

Thanks for your reply,
I had stumbled across this one also. He was lucky I think, I have un-instaled and re-instaled 4 or 5 times now. I must be doing something wrong!!! It probably wouldn't bother me so much except it works so well when it does, that it's a shame when it doesn't?? Now that makes no sense.

Cheers and thanks for the effort.

pocketpc2k2 or 2k3? I've noticed 2k2 has some strange habits...

PPC 2002,
I'm told Toshiba won't release an update to 2003 for this model?

Not sure.. I'll have a look when I'm at work (an aforementioned Toshiba supplier)

Thanks for that,
Appreciate your help
