Odds of timely D-Link DIR-882 or 878 support in 2018?

D-Link has a couple new routers with great mediatek hardware. However it looks like the mt76 driver only supports the 7602 and 7212 radios, not the mt7615? Does anybody have any insight into when, if ever, 7615 will be supported as well as the hardware in older routers like the DIR-860?


I'd like to say that these devices look very interesting to me, and I would also love to see support for mt7615 in the mt76 driver :slight_smile:

I'd be very much interested in the MT7615 3x3 radio being supported as well, but no idea if support will make it into mt76. Mostly depends on Mediatek themselves, I suppose. Last I heard, that wasn't looking good.

We really need one of the chipset manufacturers to step up their game and produce the new ath9k chipset for AC WiFi. Fully opensource drivers rock.

Keep in mind most hardware rocks a 2x2 configuration so 3x3 might be a bit overkill. It is
more future proof though :wink:

Is this just lazy speculation?


Someone on IRC said that at the moment the mt7615 driver is a bunch of quick hacks, but once it's been cleaned up (not clear when) it would make a chance of getting (upstream) support.

I'm not sure what this license actually means though, it seems to suggest this is an 'unauthorised' repository:

IRC source?

Source code is source code. In this thread, I don't hear good things about the source though. Incomplete mac80211 support. Avoid this hardware platform for the time-being.

There's 'source code' that gets you in court and 'source code' that you can use. I'm not a lawyer, but statements like 'unpublished work', 'use of a copyright notice does not imply otherwise' and 'confidential trade secret' all sound like potential trouble to me. Someone posted some Broadcom or Marvell drivers to the mailing list(s) a while ago, it got deleted - because it was code under NDA. Nobody wants to touch that with a stick. That's just a can of worms.

I too have a DIR-878. Once it is setup properly, it performs very well, and for a very low price (when on sale). That said, the stock firmware is quirky and behaves oddly at times.

The router would really benefit from some open source configuration and UI.

The main thing that needs to happen is for the mt76 driver to support the mt7615 chip. Once that has been made, developers will probably look into bringing Lede to these devices.

I posted in the H/W questions thread - does the current MT76 source support the D-Link DIR-882 which is apparently a MT7621AT (Wiki says MT7623)? I realize there's no built source but I'm not opposed to spinning up a VM to build it myself. Just more curious if I should even attempt it based on the unknown whether it's supported/working or not.

@Dekker500 Are you able to provide a boot log from the stock firmware?

@cwasser Same for you if you own a DIR-882?


I bought a 882 today, didn't want to stay on the limited stock fw so I quickly flashed DD-WRT.
Is that of any help?

$ cat /proc/mtd

$ uname -a

And dmesg, on a freshly rebooted device: https://pastebin.com/qXuJAqVb


The output of dmesg would also help developers working on the device


I realised that dmesg ran out of buffer.
Here's a log taken from serial, including uboot sequence.


What I get from the docs, because the platform is already supported it should be fairly straightforward to get a initramfs up and running, no?

It should yes, but I have no experience myself with it.

This I want to know as well

MT7621AT is the SoC and e.g. the RT-AC57U I own runs on that very same SoC. The mt76 driver only concerns the wireless radios. SoC support is independent from that. You could e.g. buy an mt76 based wireless card (like you can e.g. buy an Intel or Broadcom one) and use the mt76 driver for that card, on an x86 or ARM system.

So you mean the situation is a bit like Broadcom, that we can have it supported by OpenWrt, but it won't have wireless?

This is a really nice cheap 4x4 + 160MHz platform, I hope OpenWrt can support it soon.

DD-Wrt already support it but I prefer OpenWrt :slight_smile:

BTW, some people say 878 and 882 are actually the same (similar to archer c5/c7 old version situations), is that true?
