IF IT WORKS, DON'T FIX IT!!! 

Given that this is a security fix, I'm inclined to install it in spite of this advice.  HOWEVER:

Are there any difficulties installing the previous version (1.06 B01 -- no betas-- which I have running now) over the newer one if it causes problems?  Thanks again! -- jclarkw

Should be a problem if you follow the FW Update Process.  I would save router configs before going up or down. However I would not load any configs after upgrading from one to another. If you have a config file for each FW version, then load that config file for that version of FW that you load. Keep config files with there same perspective FW versions. I know upgrading to newer you should be save to load the config file and you can. However if you run into odd issues, you should do a factory reset then set the router up from scratch and see if there is any differences.

Just loaded this FW on top of the original v1.06 from 2015. I couldn't test wifi however wired seems fine. Visited some sites and all seems working well.

Not upgrade issues.

why is this beta only available for NA routers?
I am in Europe and would like to get a security update, too.

I believe this firmware will work for most regions. Let me find out.

[GreenBay42]

There is no mention of specific regions listed for this firmware file so I will assume it will be OK. You can always downgrade if you experience any issues.

Well, I just bricked my dir 645 using this b02 firmware
It blinks (WAN LED) and even 192.168.0.101 does not let me flash anything to it

[FurryNutz]

After upgrading FW, default settings will be reset so default web page access will be at 192.168.0.1 using default admin and blank PW.

Recommend using IE11 or FF browsers for doing any FW updates. Chrome has been known to cause problems.

Thanks for your help. I could access emergency through 192.168.0.100 (strange!) and flash FW .106b01, but then the router just showed power and WIFI LED and no connection on any IP (tried IP range scanner to find it in LAN). resetting brought me back to step 1

[naddel81]

on the third try I was able to revive it:

how can I see which beta I already have flashed? it only shows main FW version 1.06.

BTW: It would be great to include the hint to scan your IP range (LAN) with a free tool to really find the router Emergency Room IP. For me it was 192.168.0.100!

[FurryNutz]

Try loading last working fw version from your region

[naddel81]

It told me before that there was no newer FW than the 2015 released one, but there were two newer beta firmwares.
so there is no way to tell on which beta I am on, right?
