I work for a large company in Minnesota and support a product that utilizes an HP Z220 Workstation connected wirelessly to a customer network.
The version of Fedora is: 18.104.22.168-2.FC15.X86_64
The wireless adapter being used is: Anatel (lite-on) WN7600R-MV
My question is this. Assuming the DHCP server/router/customers network is not to blame (which it probably is) and assuming there is no EMI present, what could cause the device to frequently renew its IP address with the server? Like I said, lets assume the router/DHCP service has a lease of 10 days. Our device is renewing, or attempting to renew its IP address with inconsistent frequency. Sometimes its only a few hours, other times its every 10 minutes. We have noticed that the frequency of renewals DOES NOT exceed 12 hours...however it varies from 10 minutes to 12 hours and everywhere in between.
Just focusing on the software and possibly the wireless hardware, would anything in the software cause this? Would anything relating to the wireless adapter cause this? (Like I said, its most likely a server/router issue, but just humor me)
Any help would be greatly appreciated. Let me know if you need any more details. Thank You.
