Stuck commands

[Ranger802004]

I didn't run or use your script for "production." I simply tried to run it on my router to see how it works as a "proof of concept" (which I'm very familiar with as a professional s/w dev. myself). The point was that the current version of the script goes into an infinite loop because some NVRAM vars are set to empty strings or not set at all, which are not uncommon scenarios on ASUS routers. A "proof of concept" demonstration should take care of common scenarios like empty values; it doesn't have to be completely foolproof, but it shouldn't go into an infinite loop either.

Look, I get it. Nobody likes criticism, and some people are more averse to it than others even when it's constructive, as my feedback was meant to be. In one way or another, we're here to learn and if you are, I can offer some advice. If not, I can certainly move on - I got no skin in this game.

I actually don’t mind criticism at all and this may be how you write but you do seem to come off as providing a little more than criticism and you are welcome to edit the script for checking values you prefer to test with that aren’t null. Again it’s just a conceptual script.

I seem to be experiencing the symptoms mentioned here. The AC86U in question is abroad and use a vpn connection to login to it. Wifi unstable, client list not updating, connections dropping etc etc. Could these all be symptoms of issues mentioned here? Any help is appreciated.

Probably not. See post #1. SSH into the router and run top or ps to see if there are any processes that look like they shouldn't be there.

Ran the script for a day, below is the grep from trace file for the script. Lots of 'nvram get' commands get stuck!
