So my other PC connection would not connect this morning. I had to restart the router to get the device to get an ip address. So I removed all IP address reservations and turned on a different PC and they are now getting IP addresses. I had about 6 loaded last nite. Not the ones I want them to have, however they are getting addressing and internet. I presume there is a problem with IP reservations and the DHCP server. Other than this, the router is running pretty good. I'm going to leave off any reservations and will probably have to remember that this router can't do reservations at all. I tried last night and one time my Mac Book Pro would get the IP address I reserved for it, then after another reboot of the router and LT, the LT got something different. The reservations are not holding well and seem that is preventing other devices from getting any DHCP IP addresses if reservations are enabled. I could not get my iPhone 4s to connect at all last nite. Definitely a bug that, unfortunately won't be fixed.
So I think from now on, for any one with this router, use DHCP automatic IP addressing if your running it as a main host router.
Eventually mine will become a AP/NAS I think. I do like the fact that it seems to support any size drive. I have a 320Gb installed now. I did watch a movie from it connected in AP mode to my DIR-857 and streamed the movie over 5Ghz to my Mac Book Pro so it seems to handle videos and streaming just fine.
I did game on MW3 pretty good last nite. No issues. Did a speedtest today and all it at my paid ISP limits.
I think other than the DHCP reservation thing, it's a pretty good little router. Is a shame that it didn't get any more or enough FW development and QC attention. This problem should have been caught early on.
Well, been a learning experience and for $80 bucks, it's a ok investment. The unit is still usable and works.
For those needing IP reservations, I'll recommend finding a different model DIR series as you should now know, the DIR-685 is EOL. Time to move on.

I'll let the 685 run over the weekend and see how it does using DHCP only.
