August 19, 2019 at 7:42 am #3871Does switching power Off and waiting five minutes and then turning power back On fix this ?
When modem freezes, can you still gain access to UI ?

Have the same router and no freezes yet. Free RAM fluctuates between 4 MB – 10 MB free. Max 93% RAM in use.
What I did notice are the following quirks;
Router throughput WAN>LAN fluctuates between 50MBit/s – 75 Mbit/s . Only once I saw 95 Mbit/s which is close enough to the actual Fast Ethernet LAN ports on this router.
Toggling the radio ON/OFF by designating the WPS button to it causes irregular behavior. Sometimes the radio wont turn ON or OFF, or only the 2.4 Ghz radio and so forth. Seems you have to press > 10 seconds for stable behavior.
When you turn OFF the 5 Ghz radio through the WEB_ui and power cycle the router. The 2.4 Ghz radio and the 5 Ghz radio wont turn ON any more. So then you need to connect the LAN cable to get into the WEB_ui again ;-(
Have not experienced modem freeze yet, but its still early days for me.You need to login in order to vote

Hi, firmware for the DSL-N66U is indeed not available/listed, I will ask ASUS why this was not included

October 1, 2019 at 12:17 pm #4641I have spoken with ASUS and they have now added the latest firmware for the DSL-N66U to the original download link/set.
ASUS will continue to provide updates for this router model, but had assumed no demand and hence removed from list.

Edit: ASUS have just given me this direct link to the latest firmware for the DSL-N66U

Your DSL-N66U is safe for a couple for years
