We have a client location of over 300 sites with R500 over 600 AP and controlled with zone director 3000.The problem is when a user roams from one site to another, clients will lose the IP. This seems to happen more often with clients who roam from one site to another. But when will remain connected to the wireless and suddenly have an APIPA address. Sometimes it will self-resolve after a minute or so...others the user will have to disconnect and reconnect.
So please kindly help me to solve this problem and I don't have any idea for this.
Are you using DPSK and/or 11r? If you're using 11r with dpsk, you can disable 11r and see if it improves. If it does you should reach out to support. This was a bug in 5.x and is resolved in 6 for sure but we noticed it lately on a network using 6.1
Edit: The exact version it was reported in, was 5.2.1.x with # ER-8555 and resolved in 5.2.2.x We are now running 188.8.131.52.959
I am not sure if ZD3050 has similar issues, it's quite an older platform compared to smartzone. You could try disabling 11r and see how it goes. If you have voip over wifi this might cause some issues of course. 11r is very beneficial in .1x though, so find an appropriate time to test this if you have many mobile devices such as phones where fast roaming is handy.
