What are you guys doing for DHCP lease times on your wireless networks? We
have 30m with 15m renewals, but still running low on IPs. We have a large
subnet pool of /24 subnets, but I think the walk and drive by users are the
ones depleting the pools during the day. I am also seeing quite a di

Depends on how big the subnet is. I'd still keep it small just to keep
the leases open. Probably around 4 hours. That should give you a good
balance of lease time versus load on the dhcp server. If the subnet was
for a specific location were the user pool was going to be static in
size and con
If you have unlimited address space such as with NAT you might be ok.
Wireless users tend to be a transient bunch.
We found that every time a local-loop bus goes by an outdoor AP about a
dozen devices associate and grab an IP address from our open (cp) SSID.

30 minutes at Washburn as well. We had the same issue as what you

Ohio State moved from one hour lease times to 15 minutes lease times. (Be sure
to match your ARP timeout in your core with whatever DHCP lease time you
choose.)
