AE 5.7 upgrade killed my network
Network is DSL modem/router with the PC on ethernet, ethernet to the AE and wireless from there, and ethernet to a printer.
ACK!
Also happening at my work where I run a Mac lab with about 30 wired and 20 wireless clients. Similar issues where my Xserve DHCP service is running and all settings are set like they were the last two years, upgrade to 10.5 and then ran a firmware update on my Airport Extreme to 5.7, and my network flaked out. Now my DHCP service will not give out any IP addresses and my computers in my lab self-assign.
If anyone has any ideas...PLEASE!
