Cccam Settings Dissappear??????

Hi

Got a Ferguson Ariva 202e HD for a friend.

Flashed with latest EMU firmware.

Edited the Cccam Settings via Network (IP in browser) all connected and channels clearing

Unplugged in my house last night - took it to his house tonight and all the Cccam Settings were replaced by other settings (user, port, password & etc)

I then had to re-enter said Cccam Settings ?

Is this normal ? Is there a reason for this ?

p.s. Last night the PIN 0 0 0 0 was working and now its not ??????

Really?

Im fairly new to CS, he has talktalk ISP using WEP encryption.

Found it really strange?

Is there a possibility that the Cccam settings will disappear again?

Any ideas on PIN???
