I bought a XR300 on clearance, saw it had the same FCCID as a 6400v2 and 6700v3, and decided to try the 6700v3 DD-WRT firmware on it. It flashed no problem. I did factory-to-dd-wrt.chk (v3.0-r47479 (09/23/21)) from the stock DumaOS webUI (didn't do any kind of settings wipe/reset).

After about 2 hours, it seems like the basics work fine (IPv4, IPv6, 2.4 and 5GHz wifi, 1Gbps Ethernet). I heavily tested the 5GHz wifi with wireless PCVR (Oculus Air Link and a Quest 2) and had no problems, and it was even a little better than the stock DumaOS firmware (2ms lower latency and less spikes).

Only difference is the board id, looks like. Shouldn't be too difficult to add official support.

To get proper support we need things like boardid etc.

See the R6400v2/R6700v3 guide, link in my signature.

I will update the guide that it probably can also be used for XR300

Thanks for testing

P.S. If you have not already done so please also report in the build thread

It's in the wikidevi I linked earlier:
Quote:
Manuf (OEM/ODM): Foxconn U12H332 T78
PCB ID: U12H332T78
"U12H332T78" is in the header of the firmware file that is available for download.

Thanks we probably also need:
boardnum (probably: 32)
boardtype (probably: "0x0646")
boardrev (probably:"0x1601" )


With those and the boardid of U12H332T78 it should be possible to add the detect/ambitcfg/sysinit with the right values Smile

Maybe even possible to:
Code:
return ROUTER_NETGEAR_R6700V3;


So that sysinit does not have to be adapted?

not sure about this, better ask BS to do this before I brick routers Wink

Yes, a complete serial dump would be ideal; and my vote is for proper detection and identification, but that's just me. You could possibly check the Freshtomato ARM code repo for the information, since it's already ported over there... Wink

https://bitbucket.org/pedro311/freshtomato-arm/src/arm-master/

Not sure if it's in the master branch or the arm-sdk7 branch; I just happened to notice it when I caught this post and didn't investigate fully. Off to snag a bite on the way to a walk-through for a gig.

Hello.

Was any progress made? I have a few 'T78 that are unused. The one flashed to the latest R6700v3 via NMRPFlash has some issues. Is it an incompatibility, and is there something that would assist? Please advise.

TIA

Developer still needs full serial dump / cfe dump with the information already noted to port this device properly. "It doesn't just happen"...

Well, to be frank, Broadcom is of little interest to the lead developer to add device support because of the situation with proprietary drivers, and I never got an email reply from the lead developer when I inquired almost 2 full years ago (my email was sent 09/23/2021, 19:22). Not sure if I want to bother poking the bear and bring it back up. I could always acquire a device since I already have the serial adapter(s) handy, and possibly translate the required information into patches and submit them, but that requires time I may not necessarily have to devote to the cause and all I need is another Broadcom device in the bin taking up space.

Did you do a full reset after upgrading?
Lack of doing that is the usual cause for problems.

From the commandline (telnet/Putty):
Quote:
nvram erase && reboot


Put settings in manually never restore from a backup to a different build

Best wireless settings is a sticky (first few threads in this forum)
