stretch WAP suddenly not working.

I know.... I've asked about this before. Something has happened and the WAP now won't come back to life. (Headless RPI 2B running Stretch) It has been there quite happily for a long time. The power was lost to it and when it powers back up, no WAP. I tried the second USB port: Same. To check the don...

Re: Help with log files and seeing what is/was going on.

Epoch1970, I don't think so. I shall investigate that. But really that isn't the real problem. It is really more that sometimes I try to log into that machine and it is just dead. I'm just mentioning this because it may be related. Neilgl, Yes, sorry. NR - Node-Red. Oh dear! Sorry. Update. No the RP...

Re: Help with log files and seeing what is/was going on.

Thanks to all. Bit more. Dunno if this is "O/T" or not, but it is part of the problem. I am running NR on that RPIZ(w). It connects (via WiFi) to another RPI which is also running NR. The second RPI is a 2B is my "main" machine for this. It is also my MQTT broker. These two machines are on 24/7. I h...

Re: Help with log files and seeing what is/was going on.

Thanks.

I hope it helps.

(As said)

It is headless, and from past tests I remember I can't just plug in a monitor/keyboard to see what is/was happening.

Re: Help with log files and seeing what is/was going on.

It is a headless machine and it (now and then) seems to lock up.

Can't ping it.

Dead for remote access.

Thanks. Not having a go at you for the reply. That makes sense, but I can't reckon the values from the top command. On TimePi - the RPI2 - I see the column of CPU load and I can see the total makes sense. Looking at the Zero's column, the gauge is showing 100% load, but the column total is way short...

Stuck with getting WAP working again.

I was running Jessie and one day for no reason I know the WAP stopped working. After a lot of lost effort, I decided to update to Stretch. After that I went looking for links: None of them really specified which version of RPI they were for and I have been told "mixing and matching can lead to a wor...

No worries.

I wasn't meaning I wanted to go in "all guns blazing" and hack the program.

But I was told (don't shoot the messenger) that the menus are text files and can be edited.
