I am running r30356 for a week now and it seems fine, but I am not convinced that it is better than r30016 on my RevB.

Notice that I do not use AC, since I have no device that sports AC. So, max speed 260Mbps on 5Ghz 40Mhz is about top speed of my notebook.

Thank you, it took me months to get this right. I bricked my router and had to recover it using JTAG recovery. Your firmware revision for DD-WRT is the only that worked for my router. I tried dozens of revisions but they all crashed my router! Thank you again!

Edit: The latest build, like many, bricks my Rev. A 868L, but the one before it, r30432, works fine.

Can anyone recommend a stable build for Rev A1 868L that has OpenVPN working properly? Thanks.

Since we don’t require a “whole house” VPN solution so I did a few searches and found that HMA supports a Two Router Setup. HMA isn't our VPN service provider but was able adapt the two router setup to our VPN service. My primary router is the Linksys wrt1900acs-v1 (Kong build) and I have the Dlink DIR-868L as the dedicated VPN router running BS’s r30016M build. I’ve had this configuration in place for short time now and all is good.

On a couple of side notes: I recently had a momentary service outage which brought to my attention that the VPN will not auto-reconnect after service is restored so I set the Dlink DIR-868L to reboot dally @ 0600 which would only re-connect the VPN if there was on overnight outage. Obviously any ISP glitch after the auto reboot would still require a manual reboot of the Dlink DIR-868L to restore the VPN service.

Depending on your encryption levels you may have a different result but here's my experience. I have a 60/25 connection which is over provisioned to 67/26. At best even while testing with the Linksys WRT1900 as the sole router running the VPN service 25/25 is the best I could achieve. So I’m losing more than half my D/L speed regardless if I have the better WRT1900 as the single router running the VPN or if I have having the DIR-868L in second position as the dedicated VPN. I was told from our VPN service provider D/L speed loss is typical using "consumer grade routers". So the upside is the cheaper DIR-868L keeps pace the wrt1900acs as far as VPN speeds. So to conclude BS's r30016M works for me

Last build bricked my 868L Rev A totally. Does not respond to ping and the recovery mode is not working either.

Would you please post some information about the JTAG process, or did you just use serial?

Same here. I was updating software on Friday Sep 2nd, and downloaded latest from from the FTP site. The router did never come back online, and 30/30/30 reset does not help neither.

I think JTAG recovery is not for me, so I just ordered new 868l from Amazon.co.uk with total of 100€ (74£ + postage). I think that's quite good deal.

I just noticed from wiki-page that router doesn't support Hard Reset (aka 30/30/30 reset), use the Erasing NVRAM method instead.

Is anyone running one of the recent Kong builds on a Rev A? Recent builds sent mine into a reboot loop of even brick it. Recovery still works every time.

What could be the cause?

Rolling back to build 30020 each time, which runs very well.

My Rev A is on r30432 std (08/16/16) at the moment. 25 days uptime with no problems that I've noticed. I have tried a couple of Kong builds around the same time and they seemed fine.

I have not flashed anything more recent due to reports of bricking.

Hi Guys,

I despair, I have after setting up the aforementioned router
restart performed.

And unfortunately, he does not start by the power LED flashes (orange), the unit remains in "Recovery Mode".

Even if I upload the original FW via the browser, the device restarts and
stops with flashing power LED (orange).

EDIT: 30/30/30 also brings no help, the device is on 192.168.0.1 through the browser (Recovery) accessible.

TFTP, Telnet will not work.


I would for your tips, help and suggestions how do I get the router running again very grateful!

Hi everyone who struggle with this "soft brick"!

I was stucked with this problem last weekend, and it took me a moment to figure out how to resolve it.

First of all, the first "bad" build (868L Rev. A) is the 30471 one (2016-08-24). Each one since then was bad (don't know for the last one from yesterday, 30681, didn't tested it).

To recover from this "soft brick", you have to get to the router recovery page. By the way, with the 868L Rev. A, the 30-30-30 hard reset don't work. To get to the recovery page, connect your computer and your router with an ethernet cable and set your network card to this fixed IP address : 192.168.0.2. Then, unplug the power, hold down the reset button under the router, and plug in the power. Hold it for about ten seconds and then try to access the recovery page at 192.168.0.1 with a web browser. Before doing this, you can start a command line window with the "ping -t 192.168.0.1" command to check when the page goes online (normaly just 4-5 seconds).

Once you can reach the recovery page, you just have to load the factory-to-ddwrt.bin file that you can get on the DD-WRT ftp server :
ftp://ftp.dd-wrt.com/betas/2016/08-16-2016-r30432/dlink-dir868l-reva/

It's not necessary to load the D-Link Factory Firmware prior to this step, as stated elsewhere in this thread, the router can handle well this one (factory-to-ddwrt.bin). Once the DD-WRT web page is reachable (the web page will display a "completed" message, I don't remember exactly what), you can then flash the full DD-WRT build (dir868a-webflash.bin) of the same version with the "Upgrade firmware" page.

Good luck!

EDIT : Sorry, forgot to tell that after the first file load (factory-to-ddwrt.bin), the router will then be reachable with the 192.168.1.1 IP address. To get there, you can then reconfigure your network card to "dynamic IP addressing" because the router can now give address by DHCP. For the "fixed IP address" step, you just set the network mask to 255.255.255.0, no default gateway or dns server needed.

Hello spheryc,

Thank you very much for your detailed answer !
I've followed your tips and used the image from ftp://ftp.dd-wrt.com/betas/2016/08-16-2016-r30432/dlink-dir868l-reva/.

Unfortunately without success. I once linked by a video you can see how the router behaves.

WHILE the uploads is the power LED permanently orange, then it starts again flashing.

I think he installed the image not at first, and remains in recovery mode.
Here a video of the attempt to flash the image:

Incidentally, my router REV B

I think this post is exactly the error described to my router.

http://www.dd-wrt.com/phpBB2/viewtopic.php?t=301076

Can you give me detailed instructions how I should proceed?

I ordered this USB TTL cable.

Hi Tuxie!

Sorry for the mistake, but if your router is a "rev. B", you have to take the ftp://ftp.dd-wrt.com/betas/2016/08-16-2016-r30432/dlink-dir868l-revb/ files accordingly. I don't know if the rev. B has the same problem since the same build (30471), but if the build 30432 doesn't do it, don't hesitate to go back further in the past (july, june, ...). You'll shurely get a build that will work.

EDIT : when the router is in error, the led is always flashing orange. I had the same behaviour till I get to flash a good build.
