Saving defaults on the TG582n

[#1]

I am running this with firmware 10.2.2.9. I have tried to set the following but some return to the default settings:
Under Home Network
Wireless Power Save . Default is on but I want off
WPS: Default on but I want off
Encyption, Default WPA-PSK and WPA2-PSK but I want WPA2-PSK only.
DHCP scope: ...54 to ...253 as default but I want ...1 to ...100
SSID default is plusnetxxxxxx I want xxxxxx
After a reboot (not reset) these settings revert to default. Am I going to have to do a config backup and restore everytime I reboot the modem?
Regards
Adam.

Did you click the "Apply" button after making the changes?

Yes I did, at all times.

Have you tried with 10.2.0.B?
I am having the same problem with being unable to save the wireless settings using 10.2.2.9 and have put it down to 10.2.2.9 being BETA software.

As far as I can see, neither 10.x versions are production. They both have "demo" watermarked on the interface. However, I can confirm your findings. The user defaults are saved on V 10.2.0  without problem and you gain the wireles auto channel selection.
