877 Router Wireless Clients cannot communicate

peter.rowe · ‎10-30-2008

hi all,

877-w running IOS 12.4(22)T (latest)

I just noticed that any wireless clients cannot PING each other. I've never noticed this behavior before since all important infrastructure is wired.

IP address is on BVI1 and is PINGable by all wireless, as are any wired connections bridged through BVI1/VLAN1

No firewalls on clients etc, they are all reachable from wired clients (wireless IP cameras and laptops)

Any ideas?

Thanks

p.s ARP -a <ip address of wClient> does not work from other Wclient.

Router IP - 192.168.9.254

WclientA = 192.168.9.60

WclientB = 192.168.9.98

WclientC = 192.168.9.97

ABC cannot ping each other, but no problem PINGing router or any wired IP on same subnet!

Can you post a config?

I may be wrong, but my first thought is this line:

ip dhcp pool Laptop

==> host 192.168.9.80 255.255.255.0

client-identifier 0100.0e35.ae7c.cc

default-router 192.168.9.254

netbios-name-server 192.168.0.13

dns-server ******

Are you assigning this ae7c mac-address this address? What address are the other wireless devices at?

That's just a reservation for my old laptop so it gets the same IP address. It's on the same subnet anyway, so I'm not sure why it would be a problem.

Anyway, I'm not using that laptop anymore!! Wireless IPs are in the 1st post, all on the same subnet, it's not segmented by design!
