HP Wireless DHCP Problem

[amvc]

Hi

I have a strange problem, which appears only to have started over the weekend. In short, DHCP requests over wireless are timing out in the majority of cases and so IP addresses are not being renewed.

The DHCP server is a Windows 2003 machine. I have installed Wireshark on this, as well as a few wireless clients. What I see is that DHCP DISCOVERS are always received by the DHCP server from the wireless cleints, but DHCP OFFERS are not always received back at the client. They appear to go missing.

I suspect a VLAN routing issue perhaps (especially as wired DHCP requests are always dealt with and sent/received correctly), but I can't see what.

The wireless module is a HP Wireless Edge XL Module, situated in Port H of a HP 5308xl switch. I have included the config of that switch below.

Any help much appreciated.

Andrew

Fixed it myself. An upgrade to the the 5308xl firmware did the trick. Can't say why though...
