if i understand what a wallgarden is... the only page you get when you first open a browser that has the ISP logo and tells you to call them.. if thats what it is then the mac/cert you are using is one of theirs its just that it hasnt been registered yet IE its a legit mac/cert just that the original modem that contains said mac/cert is not in service, IE no one is paying for service on said modem so it hasnt been issued a working config...... so updating firmware wouldn't work unless you are getting a legit config when you logon(one that allows you to browse the web) but if you where getting a legit config you wouldn't get that page.... try checking the config with vulture
