Connection Up Time :    4 Days, 06:14:51

has been passed with the firmware update to 2.02, there are 8 devices that connects to the router. DHCP seems to allocate I.P correctly, the DIR-815 has similar issue with the DIR-685. Does not log any attempt of connection, and provides an non allocated I.P. The other topic, is that his router always provide him a new I.P allocation due to believing it's a new MAC address which is not.

So far the DHCP seems to be okay, though then again I just got home.

Now what happens if you reserve the IP addresses for the devices ON the router?
I loaded v2.01 as v2.02 is only a WPS PIN fix. I'll test it out this weekend.
Hopefully the 685 will be stable on v2.0x. I do like the features it has.

I'm not sure if there is an 2.02 NA version, the latest is 2.01. If you have a WW router, then the 2.01 firmware still has the bug. Though the NA and WW are different in terms of development.... so far the router seems okay. Only applied 3 I.P reservation, and need to check that it has actually been fixed before I go crazy adding more I.P. But happy overall leaving as it is...as I played around with the routers settings so many time.  ::

Ok well, v2.01 is loaded, I have 1 IP reservation right now. Will add more as time goes one. I have the 685 online now for the weekend.

Ya, trying to get my Iphone to connect is not happening. Even thru a wired AP, it's not getting any address. I think the DHCP server goes to sleep and doesn't wake up when something comes on line to get an IP address.  :-\

Seems to be not very seamless when connecting. I see why there is a problem. Oy vay.

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.

Well atleast it's not just me  ::), will try avoid DHCP reservation. Though my local LAN that has I.P reservation are doing just fine.... I hope

But the issue will arise after several hours, so even if you reboot the router the problem will arise later. Do you have a NA (North America) hardware?

Yes I'm in your situation, that I do like the features it has .. 1Gb ports on all available ports, any SATA 2.5 HDD, built-in Torrent Client. But the lacking QOS and DHCP support are kinda a let down...

Ya, wish they had done more on DHCP and QoS. Oh well. Does make nice NAS box I guess.

I've kept it online since friday. Been working well since I removed the reservations. No other issues seen.

I think we'll have to close this an theres isn't much else left to do.

Hope yours works out well. Keep us posted if you have any other issues. Let us know about your friends DIR-815. Maybe we can help with that. Thats a fairly new product so if there is any problems, please post over on the DIR-825 forum and we'll help out.

Enjoy.

Update - DHCP Working  :)
Manage to update my friend router, the DHCP issue seems to be resolved. The router uptime was on for a week, yet it is capable of handling DHCP allocation correctly. I notice a minor bug on the DIR-815. If you pre-set the DNS Servers you will have two set of DNS servers for your devices.... 4 DNS servers of the same primary and secondary DNS servers repeated.

Other than that the routers are working as it should be, below is the firmware that I've used.
DIR-815
DIR-815_A1_FW:v1.03

DIR-685
DIR-685_A1_FW:v2.02WW

Glad you got it working. If you have any DNS problems, Please post in the DIR-825 forum regarding this issue and phone contact DLink support so they are made aware of it. Please also post your 815 experiences there too so others will know. I added the link for the v1.03 there as well.

Enjoy.
