I have R7800's which are fine and work in a mesh, wlan0 for mesh, everything else on a VAP on wlan 1.x

I see the R9000 is tri band. Does that mean you can mesh of wlan0 (11ad), then VAP on wlan1 (11ac) and VAP on wlan2 (11g) ?

If so, does anyone know there are potential known bad blocks on the devices - like there are on the R7800's ?

The ad range is very small, about a meter, so you will need to have a pretty dense mesh of R9000's.

Maybe more than a meter and depends heavily on LOS:

Of course, Ubiquiti has 60GHz wireless bridges that have a much longer range (a couple of examples):

AD band still not that useful and more looks like marketing trick leftover...
no idea how many clients for it too... but yep if its working as a bridge mode(quite low range),its just another option for WDS or wifi bridge/client mode... but overall AD is a gonner...as AX is now on the marketing move...

bad block's ... i've seen all those routers R7800 / XR500 as well R9000 / XR 700 with bad blocks reports..so, when you get them, its a bit of a Russian roulette ..as some of them come with bad blocks by default and their stock firmware fits just about right...

thanks for the comments folks.
My R7800's are OK at the moment, but was thinking of how to get clients onto 5 and 2.4g in a mesh and knew these say "Tri".

Seen a couple lof R9000's around at a decent price which was a), tempting, b) worrying incase there are bad blocks.

To make it better... bad blocks are 'mostly' dangerous for the initial DDWRT flash from stock...where later on the new builds upgrade.bin has a bad blocks check and it will skip those...
if im not wrong.. that's why some bad blocks are fine as far as you can fit the initial flash..
i keep buying second hand R7800 with bad block, but fully DDWRT flashible...
not long ago i had one more second hand R9000 which i flashed and the guy who owned it, didn't like the DDWRT GUI - so we moved back to stock, where R9000 had a bad blocks too, as every NAND memory could have... so the window to get a BAD router is very small it must have those bad blocks on the edge of the DDWRT firmware size....

After reading this i grabbed my old r9000 that would only take a stock to Kong DD-WRT build and wouldn't upgrade further, last time i tried upgrading from the kong build it would always brick it but would go back to stock via serial. Anyway confirming i have just upgraded to r50671 via cli.
Radios still not running but that's another story.

Cool Very Happy Cool

if R9000 is operational with no radios...but the last build 50671...you can add a WAP with ease Razz

The only problem with these is the active antennas and the radio chips dying; please show us where these reports of bad blocks are.

Not sure if it was a bad block issue with this r9000 or BS has stopped fw looking for radios up during boot, but this r9000 wouldn't take newer fw some time ago but now it does! Laughing

https://forum.dd-wrt.com/phpBB2/viewtopic.php?t=328048&highlight=

My 2.4Ghz does not broadcast any SSID (doesn't show the 2.4Ghz next to wlan1 in ui even) Network mode only shows mixed or disable, The 5.0Ghz broadcasts but unable to connect just fails regardless of security settings. I have just tried a VAP on 5.0Ghz but sadly still fails to connect same issue as 5.0. To be honest not to bothered about wireless i have mesh BT system, just need to sort out 1 van for my I-o-T network and i can replace my r7800 if it continues to work as gateway router.

I am not a software engineer by any stretch of imagination. However, Netgear R9000 has some peculiarities that are not found in other Netgear products that came across my desk, namely R6220, R7000, R7500, RBK50, R7800, XR500 and R8500.

Unlike those routers, R9000 running DDWRT needs a longer wait time to complete changes made to its logical functions. And this may result in it being 'out of sync', at times, with the off-then-on pressing of power button to force a reboot. This peculiarity sometimes results in unexplained R9000's behaviors such as 'half-bricked' when power button is pressed, before R9000 completes it changes. I refer to this symptom as a voodoo of R9000.

Workaround: i) Use GUI to reboot R9000 after changes. ii) Keep an eye on the four indicator lights (starting from left) to signal that R9000 is ready. (If not making changes, especially CLI, pressing the power on/off button works fine).

This is very much the trick to 'tame' Netgear R9000.
