Hi,

I'm having issues with the wireless setup on my Cisco 857w.

I can't seem to get an IP from the router once authenticated, I just get an APIPA for the wireless connection.

Here's the config:

Is there something glaringly obvious that I am missing??

Hey Spice Weasel,

Thanks for your suggestion, I gave that a go but it didn't help the problem.

I tried connecting via the Ethernet ports and found that I couldn't obtain an IP from that interface either.

I have put a new config below, minus some access-lists and security on the wireless (I wanted to make sure that it wasn't one of these that may be causing the problem) but I'm still at a loss as to what the problem may be??

don't you have to enable the service:

service dhcp

?

 

You can try the service dhcp command, it is worth a try, but service dhcp is enabled by default. If it is disabled "no service dhcp" will show in the config.

Run debugs to watch the dhcp process when a client connects to f0 (f1-f3 are shutdown) - that should provide some useful info.

Just a wee update to say I have sorted this problem now.

The problem was resolved by configuring the BVI1 interface to have the IP address of the router, and setting the VLAN 1 and dot11radio0 interfaces to have no ip address.

Basically I just passed all the original settings from the VLAN 1 interface on the BVI1 interface.

Thanks for your input guys


Below is a copy of the working config in case anyone has a similar problem in the future.
