Re: Headless RPz(W) weird happenings.

Eventually i tried to reboot the router/AP instead of the PI, and on its return to service the Pi was available without any intervention??? Yeah, that can be annoying. I have asked about the "hotplug" option here: https://www.raspberrypi.org/forums/viewtopic.php?f=28&t=251021 That is a whole other ...

Re: Headless RPz(W) weird happenings.

(Oh great first attempt failed.) Yes, in a perfect world that would be nice. (And easy to do.) Though I can move the RPz to another (better suited) location to connect to a monitor, the failures are random. The last time it was more than a week before it happened. I don't have a "spare" monitor to l...

Headless RPz(W) weird happenings.

It has happened now a few times and I am not able to understand how to fix the "problem". My RPz(W) is connected to my WAP. (Linksys WRT 1900acs) The RPI is headless. Every 18 seconds - or so - it sends an "I'm alive" signal back to a central machine. A few times now I see the LED on it going crazy....

Re: allow hot-plug wlan0

I am sorry.

I have two BIG problems with the RPI just now.

I am getting them mixed up.

One is the RPz(W) not reconnecting and the other is a RPI (early version) suddenly not working with a new kernel being installed.

My head is all over the shop with it and I am sorry I mixed the two problems up.

Re: allow hot-plug wlan0

/etc/network/interfaces, ifup/ifdown, the "hotplug" keyword are all obsolete . Even in Jessie. What you want is the modern way of configuring network interfaces, which is event-driven: when an interface is brought up, an event is fired and dhcpcd configures networking (see /etc/dhcpcd.conf). When a...

Re: allow hot-plug wlan0

It is kind of difficult to try a different "card" on a RPz(W). The "card" is part and parcel to the machine. I really don't get the sarcasm - though I am from Oz. If that is the accepted way to talk to others, then it is not really of any help to anyone. If people know things and other people like m...

I have a RPZ(W) and now and then the WiFi goes down. Yes, that is in itself a problem. Every time it goes down, the RPZ dies. Or, more so: Is disconnected from the WiFI and doesn't reconnect when it comes back up. Reading stuff there is/was a line you could put in the file that is: allow hot-plug wl...

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...

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

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

Can't ping it.
