I feel i'm reasonably technically-minded, but this router's been a bit of a headache.
i purchased this dir-850L on 10/8 from newegg, and received it on the 16th. the 850L is replacing an older linksys wrt54g2. our wlan has mixed 11b/g/n devices, running windows 7 and xp.
1.07 firmware's been installed on the 850L, Hardware version is A1
let me start with setup. for some reason, it seems that the dir-850L either cant, or wont, get proper DHCP info from our comcast cable modem and will not be able to establish a connection to the internet (but it will if daisy-chained through the linksys wrt54g2).
i was able to puzzle out a solution, under Manual Connection Setup, i apparently MUST enter a dns server (either comcast's or google's) AND click the "clone your PC's mac address" button. manually entering the 850L's mac address (or that of the wrt54g2) will not work.
if this is documented anywhere, i wasnt able to find it.
once that's done, the router's able to get an IP address and establish a connection to the internet though the cable modem.
If you could shed some light on that issue, why that happens, or what i'm doing wrong, i would very much like to know.

second issue, low WLAN performance.
for this: Laptop will refer to a laptop running WinXP Home with an ASUS USB-N13 wireless adapter (11n) and PC running Win7 Home with a TP-Link PCI card (11g). both computers are in the same room. the dir-850L is not 30ft away, on the other side of a wall, and is configured as: 2.4ghz band in mixed b/g/n mode, auto channel scan enabled, best (auto) transmission rate, with 20/40mhz auto channel width. security is WPA-personal, WPA2-only with AES cipher. 5ghz band is disabled. all other settings should be in their default state.
signal strength, as reported by inSSIDer, is good on both laptop and PC, but transferring files between the two is very sluggish. 800KB/sec-1MB/sec at best, but more commonly around the 200-400KB/sec range or less. and unlike with the wrt54g2, transferring files simultaneously incurs a much higher latency when playing online games.
in the same vein, pinging around the WLAN, such as from PC to laptop or from PC to the router, result in wildly variable ping times, all several hundreds of milliseconds, and even pings over a full second, and that's assuming the ping requests dont simply time out, which they frequently do.

etc..
http://prntscr.com/1z8gufeven with a 50ft length of cat-6 between PC and the router instead of the WLAN, ping times will still be inconsistent and much higher than i expect them to be.
i would very much like to see better performance out of this router, if you can provide assistant in that regard.
========================
third issue, web configuration idle log-out
simply put, getting logged out after about a minute is far too short an interval, and annoying when trying to read up on a setting, or say, type up a email to d-link support.
sucks, but looking around on the forums apparently its not possible to change it.
