After upgrading to 2.1 clients loss internet and sometime IP

[poplap120]

I upgrade my personal Pfsense box to 2.1 a bit ago but had a corruption of my HDD so I had to do a reinstall, afterwards it was working for a while then the issues started. At first it was few and wide and I noticed that only some would lose internet or wouldn't get an IP when trying to reconnect. For another project I setup a static mapping for a Server and the issue got a lot worse with all clients having the same issues and more often. After deleting it it go better but the issues are still there.

Any ideas why this would happen. If you want me to pastebin any logs then I can do that

Thank you
