Hi,
I configured 2 pools of DHCP with different subnet range in my switch. The second pool leases the IP address to its client mechines and works fine.
I am having issues with the first pool. The client machines takes more than 45 seconds and I can see "Acquiring network address" and after acquiring "Limited or no connectivity" with default windos range of 169.254.xxx.xxx. This happens only while connecting through the wireless interface, but while connecting using a cable between the router and the system every thing is perfect.
I am pretty much confused, since I am using the same set of configurations and one works and the other doest work properly. I also used helper address, but its of no use. If any one know what is happening, plz help me in fixing up the issues.
Thanks
Rajesh

Hi Rajesh,
Since you are only having problems when using the wireless interface, that implies that there is a problem with the wireless connectivity, and not the DHCP server. I would suggest hard-coding an IP address on the client machines first to verify that the wireless access is working fine or not. Then, you can go about troubleshooting the DHCP issues.

Hi Paresh,
When i hard-coded the IP address, i can able to ping with other mechines on different vlans. So, we can say that commnication is taking place.
I did a search in the net and some say that its router configuration issue and others say its windows sp2 issue. But, i am not in a position to accept both. Since, my router works fine for one set of Vlan and its pool and it dosent work for another Vlan.
Thanks Paresh for your quick reply.
Regards

Hi Rajesh,
Are you in a position to run any of the following debugs to see whether or not you are receiving the DHCP messages from your clients:
debug ip dhcp server packet
debug ip dhcp server events

Hi Paresh,
I saved my configs and restarted my router. Now, i cannot ping the Hard-coaded ip which i pinged earlier.
Even now i can able to get the IP address from one pool and cannot be able to get ip from the other pool.
I have attached the configs along with the debugged output which works properly. I d't get any debugged output for the non working one.
Thanks

Hi Rajesh,
It does appear that your issue is related to the wireless setup and not DHCP since you don't even see the DHCP messages coming in. Unfortunately, I haven't done much work with setting up wireless connectivity so I can't advise you on how to go about fixing it.

Thanks Paresh.
Same here.. i also haven't worked much with wireless networks. But i have configured wireless setups using a single SSID which is up and working fine. I thought of moving one step ahead by adding one more SSID and here there is a real need.
Because of this i am redesigning my network.
Anyhow thanks for your reply Paresh.
