Hi,

I have an hp 5550 and when I connect to the Net with wifi the green light
flashes and intermittently turns to orange at random times then back to
green. I have done all the updates and returned the device to hp who
replaced the wireless module, but still no joy. Every combination of
settings has been tried.

No matter what I try I still can't get it to connect permanently. I've even
done a hard and a battery and soft reset after upgrading the drivers, but to
no avail.

I would be grateful if anyone can suggest a solution to my problem.

I would have thought that hp would have upgraded the machine while it was in
for service. They didn't seem to think it was necessary apparently.

When in the cradle the device will connect to the Net OK. I have tried
WinCE also the two utilities in the article on fixing the problem, but they
are of no help.

Thanks in advance,
Graham.

Maybe interference from another device transmitting in the same frequency band, ie. a 2.4 Ghz
wireless phone for example. Is this at home? Where are you in relation to the wireless access point
when you see signals drop out? Try changing the transmit channel on the AP to minimize interference
with other devices.

Hi Al,

I have tried it in the same room as the AP, but still the same result
unfortunately.

I also thought it may have been interference although there is nothing in
the room where the AP is located.

Thanks anyway for the suggestion. It's almost as if there were a black hole
in the house which affects 2.4 GHz!

The fault seems to be worse when I turn on IE on the PDA if that's any help
in trying to track down the problem..

Cheers,
Graham.

Can you try the 5550 device on another wireless network at a friends house or at work to see if the
problem follows the device or stays at home? Is it possible its an access point problem and not a
PocketPC problem? What access point do you have, ie. manufacturer and model? Do you run the latest
firmware in the access point?

Hi Al,

The AP is a D-Link DWL-900AP and the firmware is Ver 1.5.

I looked on their Oz site and they don't have any updated drivers.

The next thing I guess is to try my PDA on another system. It could be that
the D-Link is a bit of difficult unit to connect to.

Thanks for your suggestions.

Cheers,
Graham.

You also might try moving the access point, if possible, to another location in your house as an
experiment.
