Airport network issues

[TitanJeff]

I've spent the last few minutes reading about network issues and the Intel macs running 10.4.8. This issue may be related but I'm not sure so I turn to here.

I have a wireless network at a local college. We have a number of students connected to it to print, access a server and the internet. Sometimes, a few of the students get a IP in use error when trying to connect and must shut down and reboot in order to connect. Sometimes no error message appears at all and they just can't connect.

Any ideas as to why certain laptops have issues? Any recommendations? It appears to be the same computers each time.

I had one new Intel today where rebooting never solved the issue. I assume it may have to do with the same errors others have had. Has Apple offered any solution I might pass along to this student?

Thanks for any help provided in advance.

I wanted to give this another shot. Any suggestions appreciated.

Without knowing too much about your network, I think it may be a DNS Server issue. Instead of restarting the machine next time this happens, try pressing the Renew DHCP Lease button in the Network pane of System Preferences. While you're there, check the DNS Server settings with the other machines that are working normally.

you are going to troubleshoot it. considering it a university, I am assuming you are using something like Cisco Aironet.

are they dropping connection the access point or is something going wrong between the dhcp server and the WAP? have you checked the logs of your dhcp server or the logs of a WAP if you are logging that?

Many thanks for the replies. We are a small college with not much tech help. I'm working with the tech guy (who really only knows the PC) and is turning to me for mac help. I'll give this a shot and see what happens.

Are the PCs able to connect? There is a problem with airport and intel macs running 10.4.8.

I rolled back to 10.4.7, and it hasn't disconnected since. Uptime of about 12 days, sleeping the imac frequently.
