I have a WZR-HP-AG300H running DD-WRT build 17798 broadcasting and it runs great. I have it set up to reboot once a week and I never have to touch it, it just runs perfect.
I have a WZR-HP-G300NH2 running DD-WRT build 17798 sitting in my entertainment center (open air so it's not a heat thing) and it's set up as Client Bridge (Routed). I also have it set up to reboot every day to try to combat this issue. I have a PS3 and a HTPC plugged into this router and primarily use the HTPC. After some use (I have yet to determine exactly how much but a few hours of streaming will do it) the router will lock up and become unresponsive, unplugging and replugging it back in fix the issue. I have looked at the system info and everything looks fine, memory is always mostly free (44MB free / 60MB total), I rarely have a bad packet, and load averages are always at 0.01,0.01,0.00.
The WZR-HP-G300NH2 works beautiful except this lock up thing. I was running the shipped version of the firmware (version 15???) on this router but updated in hopes to alleviate this issue, updating helped but did not eradicate the issue.
