I have a G4 ibook 10.4.11 that will associate to our Cisco Access Points at work. The problem I am finding is that the Network Manager seems to "lose" the DNS servers that are served up by DHCP. This is an open 802.11 network, NO security enabled what-so-ever. It is our public internet for patrons to use.
When the laptop "looses" the connection, I can still ping local network IPs by name, and internet addresses by IP but not by names.
If I enter a new DNS entry into the Network Manager on my MAC it starts working again.
What would cause this? Interestingly enough I found another user of a new MacBook Pro (OS X 10.5.5) who's airport card won't even list the wifi networks, or connect. the DNS trick on mine does not work reliably on the MacBook Pro.
This leads to the last question: How do I find and upgrade the firmware on the Airport card? I cannot find it on Apple's website, that does not require OS 9.1??? and Firmwares dated 2001! I found this thread on Apple's website:
Apple - Support - Discussions - MacBook Pro will not connect to Cisco ...
There are apparently LOTS of Mac Users in a Cisco Infrastructure with connection problems.
Of course all Windows based clients work fine.
I am no expert in the Mac world, either. But I can troubleshoot.
Thanks in advance!
