Has anyone encountered 8841’s dhcp timeout after attempting to reconnect from loss of wireless signal? My 8841’s are continuously moving between buildings and wireless controllers. Occasionally they lose wireless connection, when attempting to reconnect, I get a dhcp timeout and the connection attempts stop. It has become an issue with multiple wireless phones.

I apologize, I made a typo on the phone model. The wireless phones are 8821’s I’m sure you gathered that from the description. The phones are all running the latest firmware.

was there any change in the environment or was this behaviour always present, but increased?
find hints in the lVoice Over Wireless LAN (VoWLAN) Troubleshooting Guide
you mention multiple wireless controllers
1) do these have a common DHCP scope/subnet for the phones? or does each has its own scope?
check this document section roaming between subnets
2) are all WLCs in the same mobility group ?
the phone may "hang on" to the old ip-address too long before requesting a new one
