Good day, first time here and not the most intelligent of when it comes to networks.
Here is my issue (both with the 1.0.1.8i and your beta), I love the features but the enable radio timers do not seem to work well.
I tried the beta (I think you are on the right track) because I have had issues with the Enable Radio not shutting off as scheduled and catching my daughter streaming video from the internet in the middle of the night. A reboot seems to correct the problem.
I have tried to disable individual devices with the beta and it did not work (caught daughter surfing at midnight). So I went back to disabling all of the 2.4G on schedule again. Now I have discovered that the radio isn't turning back on in the morning and when I go into the settings the Enable Radio button is clicked off.
Any ideas?
The radio schedule is half broken in some versions of the firmware. Asus fixed it in the recent 178 release for other routers, so you'll have to wait for Asus to release an update for this router with this fix.
