I have about 30 access points, connected and receiving reserved ip addresses from windows server 2003 dhcp, all running this version of software:
System Software Filename:
System Software Version:
I have MAC filtering set on them. Clients with authorized mac connect, get ip's, and can do network activity. After about 5-6 minutes, DNS issues begin to occur:
During testing, streaming radio continues, network browsing continues, but browsing the internet stops. I can't resolve websites through address names, but I can browse to sites using IP addresses. As soon as the page calls for a www.whatever.com, there's nothing. Any hints?
As I have this conversation with myself :P, it seems it's just certain wireless clients. I've tested a gateway 7500 fx laptop and hp laptop and they work fine with my setup. So it seems it's a driver issue or setting on the driver (nic) that's incompatible with the APs. Does anyone have any idea of what?
Okay, after a support call to Cisco and many days of back and forth with settings, cli, resets, disable this and that...the problem is that in the web interface you do not apply mac filtering to the Apply Filter section like in Figure 10-2. You just add the mac addresses in the MAC Address Filters section like in Figure 10.1(all interfaces should have like in the figure) .... The end result is clients won't associate to the access point unless added to the 10-1 section if Default Action is Block all and Filter Classes are set with MAC Addresses to Forward. Again, don't actually apply the filter in the apply filters section. I don't know what logic this is, but this is what is necessary. This applies to CLI and Web interfaces.

This is the start of a display filter cross reference between Wireshark
and OmniPeek. The 1st installment is a table of advanced filters. More
filters will be added as time allows. It is a living doc, so check back
