Just getting started with WiFi, could someone please let me know the affects of having a wrong ip name-server defined? Apart from not being able to ping a host name on the cli does it affect connected clients?
Thanks in advance.

That's about it .. Clients should still connect. Just can't use their name ..

Thanks, I've just started playing a bit and trying to figure out why our iPhone and iPad users are getting some issues. Found that 5 of the 7 1200 series APs had the wrong Name server. All corrected now, iPhones and iPads still seem to have problems connecting after wake, thinking its a client issue after reading a few posts about it.

Autonomous or controller ?

Autonous

IP address of the DNS server is specified with the ip name-server command. So, if you have wrong ip name-server defined you will not be able to reach or ping the hosts outside your subnet.

In my case the correct DNS was being supplied by my MS dhcp server, just unsure if the incorrect name server settings in the APs was adding to my connectivity woes.

So the DNS the client has is where the DNS will get resolved ..

Just for the benefit of anyone reading this... I couldn't post my config due to privacy. But George directed me to the fact that there is a known issue with Apple devices when using mixed modes.
Standard is WPA/TKIP and WPA2/AES
On pre 12.4 IOS the authentication option "authentication key-management wpa version 2" is not available, so either upgrade to 12.4 or stick with WPA/TKIP.
First time I've taken part in Cisco support forum other than reading posts. If I get responses as quick as this I'll be an active member
