anyone here have tried this newer firmware?  it is not yet showing in router's auto update firmware page.

GreenBay42:
Correct. This is still considered a BETA firmware which is not pushed through the auto update server.

I haven't heard of any issues with the beta. If it doesn't work you can always downgrade back to the older version.

hydra3333:
thank you for the information.

happyhere:
any DIR-885L owner who was  braved enough to update to v1.21B03 ?   

I am still on v1.20 for more 18 months now and find it stable, if aint broke then dont fix motto. 
Anyway, yes I would like to have that KRACK fix.
But this 885L is my main router with 25 to 35 devices (e.g. repeater, AP, IP cams, IOT, smart devices, pcs, phones, etc). Downtime will be nightmare for households users, seems internet is a must thing now :)

I really love this 885L, the CPU is great and able to handle video calls with ease even with dozens of devices, qos off.
