In a nutshell, my venerable, decade+ WRT54GL started going flacky, and recently quite so. So I picked up a second hand WRT1200AC (Rev A02, if it matters) for a song to replace it.

Recommendations on what dd-wrt version I should make use of for it? (I did some cursory searching before posting, and it appears there's some trade offs between either a version that biases towards the ethernet working or wifi working? If so, I'd lean towards making the former rock solid. And I have a UAP-AP-Pro I'll likely try to make use of, so I may turn off the WRT1200AC's wifi entirely anyway.)

So that's a V1? I don't have your router, but Monza has been reporting in the most recent build threads with no major issues (WRT1200AC v1).

I'm running 12-29-2019-r41813 currently and waiting for the next build after 01-14-2020-r41986 but again different routers.

If you can find a used EA8500 or R7800 they are highly recommended. I recently put my WRT3200ACM back into its fancy box.

There is nothing against an 1200 ac v2. I am using it, with no issues. Everything works fine and stable. Ihave wlan 2.4 and 5.0,vpn client usb support and nas. Everything works priity well. At moment realy stable version is DD-WRT v3.0-r40009 (06/11/19).

Nothing wrong with 1200 series; I was trying to clarify as revision and version are not the same thing. I confirmed Rev. A02 should be a V1 though.

Not a big issue either; it appears V1 and V2 firmware are binary identical.

I agree r40009 is a great baseline stable build for Marvell WRT series.

If jumping between current builds and r40009 it's advisable to reconfigure from scratch and keep backups for each.

The models I recommended are because they are very well supported by DD-WRT. With people having "upgraded" to mesh/ad/ax the used router market has a lot of good deals.

I'm still on r41813 as kernel samba is still in development, but looking forward to a build after r42114.

Many thanks for the replies all.

I'm accordingly starting with the v3.0-r40009 (06/11/19) build recommended.

After an unsuccessful attempt, I'm a bit discombobulated on the process though. Apparently I'm not supposed to do an old school reset on this type of modern router? And am I supposed to do a reset after factory-to-ddwrt.bin and before ddwrt-linksys-wrt1200ac-webflash.bin, or am I supposed to immediately upgrade to ddwrt-linksys-wrt1200ac-webflash.bin after the Linksys successful firmware upgrade message and then reset... in a non-oldschool reset sort of way?

The factory-to-dd is for initial flash. Webflash is for upgrading to a newer version. The two methods to reset are reset button for x seconds until the panel light(s) do their thing, or in the firmware webUI "reset to defaults". Some folks are adamant about going in via telnet or ssh and doing an 'nvram erase' via CLI, YMMV. You should be able to upgrade to the latest build (42335) without much issue.

Now squared away. I found I had to use an older factory-to-ddwrt.bin.

11-Jun-2019 and 10-Feb-2020 factory-to-ddwrt.bin were unsuccessful. With those two: After successful firmware upgrade message in Linksys, I got a router rebooting (only option to click OK), Waiting..., and then within Linksys realm got a successful firmware upgrade or the like message. And reset or power cycling left me still within the Linksys firmware realm, hence my confusion if I needed to do something in addition to the factory-to-ddwrt.bin when within the Linksys realm.

Success with 26-Mar-2018 factory-to-ddwrt.bin. After firmware upgrading to that in Linksys realm, I left the computer and when I came back -- glorious dd-wrt.

From there I was home free. After all this fun, I successfully webflashed to 11-Jun-2019 for now, since it's apparently know for its stability. I guess I should check in or arbitrarily try a newer version every blue moon or so for security reasons?

Thanks all. Now I've got to read up on all the new configuration aspects introduced since the WRT54GL era..
