Ok I'll have a go at updating it, I did try updating it via the admin login but said illegal file or something, I'm guess that's due to not having zyxel standard firmware upgrade permissions due to john lewis, so will superviser login allow me to upgrade ?, and is it just a case of upgrading or do I need to wipe the rom-d before, and will the passwords still be reteviable via the csamu command ?
Thanks
