I have the same setup as you, Oliver, a EPC3925 cable modem with WNDR3800 connected to it as second device so I am able to fight buffers where I have access.
What I started doing last week though is I deployed an additional WRT54GL for emergency, including family use if I make WNDR3800 inoperable. I connect it to the cisco cable modem. For the WRT54GL I am using Hector Ordorica's Tomato RAF build with some anti-bufferbloat changes, for the broadcom chip buffer size, txqueuelen and around qos: http://ordorica.org/blog/tomato-firmware-wreduced-bufferbloat Hector is not doing any further builds, but it gives very good results on netalyzr. This allows me to tinker away with WNDR3800 and if I break anything, anyone can still use the WRT54GL. Yes, this means I can have competeng traffic on the router, but the 54GL is for emergency use only.
