I have recently moved from ADSL (tpg.com.au) to unwired wireless (unwired.com.au). Other than enabling PPPoE, and editing /etc/sysconfig/network-scripts/ifcfg-eth1 to set BOOTPROTO=dhcp & ONBOOT=yes to get the thing to work at all, nothing else has changed.
I now find I can't access a number of websites, which I could previously. Among these is msn-messenger (don't blame me, the kids insist on it), ebay.com.au myaccount, hotmail, westpac online banking, and I'm sure many others I haven't discovered yet.
I found a reference on whirlpool forums about msn-messenger needing to have the MTU set to 1456 or 1440. I tried connecting the unwired modem directly to a windows machine, installing Dr.TCP(.exe), and setting the MTU to 1500 (same as the SME server) to try & replicate the problem, with no success.
Does anybody have any experience with getting SME 6.x to work correctly with unwired.
I might add this setup worked perfectly for several years with adsl before the move to unwired. I also have two other SME installations in remote parts of Australia running adsl perfectly.

EDIT:
searching through the log files, it appears it's not authenticating; repeated attempts to connect ending with CHAP failure.
EDIT #2:
Figured out unwired don't use PPPoE. Just set it to DHCP (send username).
