I get the same problem as well. Wired or wireless,
Unifi can be pretty shit when it comes to PSN matters
Mine also like that, DC after a few minutes everytime. Seems like the router detect the PS3 is in idle then DC its connection. I dunno, just my speculation.
So I bought a new router and use that instead. Below is what its like :
[TM fiber whatisitagain] --> [TM router] --> [My router Belkin] --> [PS3 in DMZ setting, wired]
My TM router is using google open DNS.
This settings never give me DC anymore

You guys should try. The downside is you need another plug hole for an extra router...
