Yesterday, I updated my AEBS to the firmware 7.4.2. After that I can't connect to the Internet through AEBS using airport in my MBP any more. I can still using the Internet thru the Ethernet port (also thru AEBS) but not by airport. It happens to every other devices at our office such as: iPhone, Nokia e71, iPod Touch... It shows that we still connect to the AEBS, but with self assigned IP. my MBP is updated to the latest patch of Leopard (10.5.8 and the update after that) and can connect by airport to other network not using AEBS normally. Could anyone help me in this situation or have experienced the same thing and got the solution? Thanks in advance.
