Re: Stretch | Not able to rename network interfaces any more

Ah, good to know, thanks for tracking this down! This only happens on upgraded Jessie-to-Stretch installations, correct? A fresh stretch shouldn't have that in /etc/systemd/network, and none in /lib/systemd/network either.

Re: Stretch | Not able to rename network interfaces any more

When it comes to systemd-networkd in Stretch, I'm reminded of Monty Python's "Norwegian Blue" sketch: "no Sir, your networking isn't broken. It just, erm, sleeps."

Re: Stretch | Not able to rename network interfaces any more

Can you try to run "sudo udevadm test /sys/class/net/..." to see what rules udev takes into consideration? This is a fry-run and should give be a fairly lenghty report, from which you can diagnose the order of rules. It was only this that allowed me to find the 73-usb-net-by-mac.rules culprit. And y...

Re: Stretch | Not able to rename network interfaces any more

I've found out after a long investigation, see also https://askubuntu.com/q/947519/723098. Someone enabled MAC-based naming with priority in Raspbian without giving much thought to what the kind of hell she or he is going to let loose. Luckily, there's a fix: the impatient reader can skip right to t...

Re: Can't find new Jessie version of Raspbian OS

Jessie isn't EOL yet and receives fixes. I really find the Foundation's behavior regarding dumping Stretch on the (unsuspecting) masses irritating, especially by removing the easy to find download links. Anyway, see here, as it is actually quite difficult to google: https://downloads.raspberrypi.org...

Re: Headless WLAN with Stretch, how?

Does a "plain" wpa_supplicant.conf also works, one that only contains one or more network= blocks?

I'm asking because I also failed in preparing a fresh Stretch mSD for headless boot.

We have made no official statements, so not sure what you are referring to. Also, this release is based on Debian, with a few Raspberry specific changes, which do not affect net naming, so this is a Debian issue, not a Raspbian one. When Debian released Stretch, we did a Raspbian version and starte...

At least I finally found out why the stock Raspbian Stretch (as Debian and Ubuntu) don't allow (re)naming USB network interfaces to specific names, but instead insist on using MAC48-based names. And this is relevant to the Pi computers, as the Ethernet network interfaces (and the WLAN) are connected...

Using the officially posted "fix" for returning to the "unstable", yet stable naming scheme by setting the appropriate symlink caused my wireless LAN interface to completely disappear. Well done.

We're talking about even breaking the internal wireless LAN. Now that is something I expect from Windows 10. But not from a Debian distribution. And not from a Raspbian distribution tackling the educational and maker markets. And the official fix breaks the system. Good work!

This feature is toxic on Pi. I call for an rpi-netmods package that would install automatically one of the methods documented for disabling this.

I've also seen undervoltage warnings with the Pi 3B + 7" Touch LCD + 2.5A power supply when feeding the power to the display control board and through it to the 3B. This setup has too many connectors and thin wires in series. Also, the dedicated micro USB Y splitter cable from The PiHut/Adafruit cau...

There are these kwel colored and flexible antennas with the two 8pin connectors at each end. Available in different lengths, to match with where your access point is. Very fast.

As always, wireless sending and reception heavily depends on your specific setup and surroundings. There ain't such a thing as an ideal setup, much the same as there isn't a pot of gold at the end of the rainbow. Even your body with so much water is a terrible thing to have around radio systems.
