Just an update -- Still running stable since the update. 5GHZ works fine for me. 150 Meg / 35 up cable network - can max it, even on the 5ghz via android.

Firmware: DD-WRT v24-sp2 (04/01/15)
Time: 08:38:40 up 14 days, 41 min, load average: 0.27, 0.26, 0.21

Build 26635

Merlin and Asus firmware would lock up randomly.. at least once a month requiring a physical power down/up.

No more dropping wifi (happened all the time on the Asus OEM firmware / Merlin).

I have tried several recent builds including 26635 and 26866 on my AC87U and all of them are giving me sluggish download speeds. www.speedtest.net results look fine but downloading real files I'm only seeing 20 to 50 mbit. Changing to Asus firmware and I'm maxxing out both of my connection lines on the same files. The connection lines I'm using are a Comcast 105, and a FIOS 150. This is directly connected to the router.

I wish DD-WRT would use same QoS as TomatoRAF. The one in DD-WRT is rubbish. But TomatoRAF still doesn't support this router... Sad

Btw, has anyone tried overclocking the RT-AC87U? How high did you get it without stability issues? The CPU temperature seems a bit high at 83°C with stock already, is this value correct?

Also, why is connection light violet instead of blue (or red)? Have never seen it like this with stock ASUS firmware...

Why is hard reset not working after failed overclock? I can't reset the damn thing!?

Why is dd-rt QOS bad?

http://www.dslreports.com/speedtest

allows to test how well qos is working.

On my R7000 with OQS enabled + FQ_CODEL the result displays grade "A" which is really good and shows, that dd-wrt qos does extremly well.

I would really be surprised if tomato, which only comes with an outdated kernel, can beat that.

QoS doesn't even work properly anymore, since the changes in r26825 & later. I guess nobody bothers with reading this: http://svn.dd-wrt.com/ticket/4093

Looks like AC87U needs WPS reset as well instead of normal reset button... Or maybe I just got damn lucky...

Why DD-WRT QoS is bad? Because it lacks fine tuning of Tomato RAF's QoS and also the awesome interface that one has. And DD-WRT has no Layer7 control from the looks of the interface. And even if it does have it, seeing the list of apps/protocols there, it's either not functioning or it's very poor.

When I've set QoS on my old Linksys E4200 properly using TomatoRAF, I could do everything and once without any service suffering. Here, it just doesn't feel like it.

Same goes for original ASUS "smart" QoS. It just doesn't seem to register certain network content properly and it just gets stuffed or out of buffer when you need it the most...

Hello, so I just flashed mine from build 26635 to 27119 and it has been running well. However, both builds give me a problem that every time a new device is connected to my 2.4 ghz network, the WiFi would drop for like 30 sec and then come back on. Anyone know why this is happening and how to fix this? I have 50+ devices connected to the router wirelessly and using bandwidth at all time. Router with this specs should be able to handle this load just fine right?

Do we have a set of instructions? I cant find them in the forum. It looks like I need to preload a special firmware before I update the firmware to DD-WRT. But I cant find that firmware.

Just load any beta firmware for the AC87U, no need to upload a special firmware first.

Hello , excuse my bad english .

I have the latest beta version installed by 05/06/2015 .

But now I have the problem that when the AC87U is restarted, he is no longer easily reachable .
On the first Lanport I get no connection, he is virtually dead .

I have to restore the router with the Recovery Tool .

Latest Stock firmware is installed and a reset has already been attempted.

many thanks

Probably bug http://svn.dd-wrt.com/ticket/4141 introduced in build 27147. You could try previous 27119.
