actually his post is a lot of sense.
The impression I get from reading the forum is people keep upgrading to the latest all the time blindly assuming everything is always better.
Whilst buffed up security is nice imo stability comes ahead in a secure home environment.
The reported asus fw security issues can be mitigated via good configuration.
If you have a fw thats working well for you, then its very good advice to stick with it, leave it alone.
374.40 was working reasonably well for me, but now I have a new wireless issue that appeared out of nowhere, suddenly my s3 phone has torrid download throughput on 5ghz, I had numerous issues with 5ghz on android tho so I am not blaming the router as of yet, I am guessing when I test using my 5ghz dongle on my spare pc it will be fine. I have the ac-66u not the older device.
Of course one reason asus maybe not complying with regulations is the fact routers ship with incorrect regions that are hard coded not configurable. I cannot set the UK wireless region on my router.
