Just update my MR3420 V2 with HM2013-12-20red.
May I know how to setup Modem Keep Alive function?
Follow the step on Post #2
But there's no option to enable this function:


And under "Modem" > "Connection Monitoring" page, do I need to make any configuration on these three options?


Lastly, how can I get 300Mbit/s? It only show 72.2Mbit/s under "Network" > "Wifi" page.


Thanks in advance
