I wrote a combination script for people who have signal fade that is strange. I have a major backhaul that for days or weeks will work great with a -64/-68 signal, then one day it will keep dropping and have a -88 signal. Change it from 5745, to 5755 (for superchannel) or 5765, and it works fine again. A couple days later it will have to go back to 5745 to work again or suffer from signal fade.
So instead of being bothered by phone calls on the nights / weekend, I wrote this simple combination of Netwatch, Scheduler and a Script. I run superchannel, for those of you who don’t, change the +5 to +20, and the 5775 to whatever you want the high number to be and 5745 to be the low number.
Here it is:
/system script add name=“setNextFreq” source=“:local f1\r\n :set f1 ([/int wireless get Backhaul frequency] + 5)\r\n :if ($f1 = 5775)
do{\r\n\t:set f1 5745\r\n }\r\n /int wireless set
Backhaul frequency=$f1\r\n”
The scheduler item:
/system scheduler add name=“setNext” on-event=“/system script run setNextFreq” interval=20s
The Netwatch entry:
/tool netwatch add host=—THE OTHER IP ADDRESS-- timeout=1s interval=2s up-script=“/system scheduler disable delayStart\r\n/system
scheduler disable setNext\r\n " down-script=”:delay 15 \r\n/system scheduler enable setNext"
This whole bunch of stuff basically does this:
- When the Netwatch IP goes down, it activates a 15 second delay.
- After 15 seconds, it changes the channel, and waits 20 seconds.
- If the Netwatch IP comes back up, it deactivates the channel changer.
- If it doesn’t, it repeats until it comes online again.
Hopefully this will help someone, I couldn’t find anything like it on the forum.
