I need help with 2 issues I'm havingwith my e51.
1) We keep a list of allowed MAC numbers allowed to use our wifi (shared place

) and our D-Link router does not like the my e51's MAC number format which contains ":" instead of "-". What can I do?
2) At certian hotels with free wifi I manage to connect with my laptop but not with my e51 although the e51 reports 90-100% strengtht signal. Where's the problem here?
