We have the same problem, and according to our supplier we had to use the Regsave for saving the settings, due to internal proceudres, we haven't use the devices for a year, but now we have to use them again....
We have found this solution in the net, perhaps will help you...., now we are trying to find out the RegSave utility, if you find it, PLEASE e-mail me at firstname.lastname@example.org
Some brief notes about the use of RegSave on Symbol 90X0 terminals, specifically the 9060 with the 802.11b RF option.
You will need RegSave_2_53_04.zip
Unzip this and locate the file RegSaveCED.exe in the 9050 folder.
Connect your terminal as a guest in ActiveSync and explore it using Win Explorer. Locate the c:\applications folder and copy the RegSaveCED.exe file to this folder on the HHT.
Now you can uncouple the HHT and click start menu and Windows Explorer to look at HHT's local files. locate applications folder and locate the RegSaveCED.exe file... double tap
Now screen RegSave EMEA TS appears.
In Registry section press "Create Template File"
Accept \Application\RegSave.tpl option offered
Click Create template and wait forever !
............. time passes ..................
The app rattles through all the registry entries and builds a file with them all in. Just when you assume it'll last forever it stops...
Now back to the main screen ...
Click OK (top right) to exit the app
--- oOo ---
Now set your IP parameters and RF bits... in fact anything you need.
........... time passes ...........
--- oOo ---
Now re-load the RegSave app.
Press the button in the Registry section entitled "Save Current Configuration"
I got some missing file error here which I rode over roughshod... basically it's looking for a registry exception file. You can create this but and it can be a list of ignored keys but for our purposes it doesn't matter so I just said "Yes"
It'll do some stuff regarding comparing and checking for differences, then it saves the changed bits.
Now you can exit RegSave and try rebooting... it should have saved the changes to the Registry and everything should be the same as before
