WiFi Slow after 2-3 days until reboot?

To those whom is using RBK50 and Voxel's customized firmware. And has wifi speed drop down after reboot about 2-3 days later. 

You can login the backend to set up cron job to schedule reboot. 

Here is how and dependancy. 

1. you are using  Voxel's customized firmware or able to login by SSH. 

2. login into the router such command like :

ssh -l root ip.address.of.your.router

input your password which same as you webui login password.

crontab -e

then press " i " for input. Here is the command. 

00 02 1,4,7,10,13,16,19,22,25,28 * * /sbin/init 6

which means: “At 02:00 on day-of-month 1, 4, 7, 10, 13, 16, 19, 22, 25, and 28.” kill all process and reboot gracefully rather than forceful unmounts filesystems and restarts the system.

you can check here: https://crontab.guru/#00_02_1,4,7,10,13,16,19,22,25,28_*_*

then

press " Esc " and type " :wq "

to write to file and quit edit window. 

to verify all set, you check as this command:

crontab -l

and you should see "00 02 1,4,7,10,13,16,19,22,25,28 * * /sbin/init 6" is there. The rest is wait and see. 

Oh, btw, it looks like RBK router has not showing system up time on default homepage. But you can check it here:
