I think this has to do with the fact that dd-wrt doesn't do CFE and CTF hardware acceleration. See this discussion about it:

860L is a single core arm processor so the performance will be a lot worse than dual core R7000 or higher end models such as Linksys WRT1900AC; Kong confirmed in other posts that WRT1900AC is capable of runing full gigabit with DD-WRT, R7000 is still only capable of ~700Mbps.

Exactly, that is the other issue. The single core processor can come close to 1000mbps with the help of hardware acceleration in the stock firmware (with QoS disabled). Dd-wrt doesn't have the hardware acceleration cheat, so it will take a performance hit. The only options you have to increase the throughput in dd-wrt would be to try to overclock the CPU a little bit. I doubt it would bring you up to 1000mbps though.

Active Wireless Physical Interface wl1 [5 GHz/802.11ac] is connected, for example, smartphone, makes the power indicator glows orange. It's all right?

I can not fix this problem. If I unplug the device from the interface 5GHz, cleaning Internal Flash Storage, it returns the power indicator is green. But connected at 5GHz, and the orange light again.

Does it work? Who cares about the lights then.

Just wanted to say thanks to those people who delved into this router model and posted all the helpful info.

I live in an apartment where I have an office at the end of the hall where the cable modem and router are hooked up but I can't run a physical line to the entertainment center in the living room where I have a smart TV, gaming PC and console.

I ended up buying a new ASUS router with external antennas and I took my old DIR-860L and flashed it with dd-wrt. The result is I now have a fantastic client bridge for the living room that is polling 585Tx/866Rx. I can run speed tests from my gaming PC and get the same 130 Mbps down as I do on the wired connection in the office.

Very happy! Very Happy

Anyone notice the CPU is a bit toasty even when idle?

Around 67c when load is about 10%

I feel like a heatsink would do wonders for the performance and longevity of this thing. Has anyone cracked one open before?

The 860L has heat sinks. I think all that would be required would be to attach a fan to the top of the case to provide better cooling.
My 860L is running at 1000MHZ and the temp is 70.2C (ambient temp in my home around 70F). I have had no problems with my 860l running at this speed or temperature.

These are normal temperature, my 860L is running at 67°C @1000MHz clock, while the Trendnet TEW811DRU is running at 85°C @800MHz, same BCM47081 and both never had any problems, all have been running 24/7 for over a year now.

Thanks for that info about the temperature. Also guys, I am unable to do any virtual interface (guest network). I followed several guides religiously and can't get DHCP working on the Virtual AP.

I have guest network working with dhcp fine. Can't remember what guide I used. If I find it I will post the link. I think the trick was to click save or apply at every step.

I'm using build 28647 and I used the instructions from here:
http://www.alexlaird.com/2013/03/dd-wrt-guest-wireless/

Clicked save and apply at every step. I added these rules to the firewall commands: (use br1 instead of br2) I used br2 because I have another router assigned to br1 already)

iptables -t nat -I POSTROUTING -o `get_wanface` -j SNAT --to `nvram get wan_ipaddr`
iptables -I FORWARD -i br2 -m state --state NEW -j ACCEPT
iptables -I FORWARD -i br2 -o br0 -m state --state NEW -j DROP
#aditional fw
iptables -I FORWARD -i br0 -o br2 -m state --state NEW -j DROP
iptables -I INPUT -i br2 -p tcp --dport telnet -j REJECT --reject-with tcp-reset
iptables -I INPUT -i br2 -p tcp --dport ssh -j REJECT --reject-with tcp-reset
iptables -I INPUT -i br2 -p tcp --dport www -j REJECT --reject-with tcp-reset
iptables -I INPUT -i br2 -p tcp --dport https -j REJECT --reject-with tcp-reset

Yeah, that is the guide I used. I've tried it on a few different builds as well. I will try it on your build sometime here soon. I spent about 3 hours on it this past weekend and was pretty bummed I couldn't get it going.

Am I correct in thinking you can just create the virtual interface and connect to it like it's your primary wireless? (obviously on the same subnet).

I'm just trying to go through the steps and see where things stop working.
