Message-ID	<EiG9P-cINS-9@gated-at.bofh.it>

Hi, I'm using a USB dongle to connect an old desktop machine (updated
debian-stable) to my home-WLAN (Wi-Fi).

This is the hardware:

```
$ sudo lsusb -v
Bus 001 Device 007: ID 148f:7601 Ralink Technology, Corp. MT7601U
Wireless Adapter
Device Descriptor:
  bLength                18
  bDescriptorType         1
  bcdUSB               2.01
  bDeviceClass            0
  bDeviceSubClass         0
  bDeviceProtocol         0
  bMaxPacketSize0        64
  idVendor           0x148f Ralink Technology, Corp.
  idProduct          0x7601 MT7601U Wireless Adapter
  bcdDevice            0.00
  iManufacturer           1 MediaTek
  iProduct                2 802.11 n WLAN
  iSerial                 3 1.0
(...)
```

Working fine til just now, then (after system upgrade) it stop giving
me connection (ip route: nothing).

I tried to ifup the interface:

```
$ sudo ifup wlan0
[sudo] password for desktop:

```

Then checked journalctl:

```
$ sudo journalctl -b -exp3

```

Tried renaming the interface with:

$ sudo ip link set wlan1 name wlan0

But it was unable to connect:

```
$ sudo ifup wlan0

Apparently until I restarted iwd.service and tried again.

And this is all I have in dmesg that seems relevant:

```

I think some HDD errors slip through (I have to fix that also...),
sorry, please ignore them.

Seems to me like the interface changed its name without reason.

Any hint what could had happened?

Thanks a lot!

Hi, it just happened again.

'wlan0' is no more, instead I have 'wlan2'. Apparently this fixes it (manually):

```

Any idea why the name-change and how to solve this?

Thanks again.

Does "system upgrade" mean more than, say, apt-get upgrade?

I recognise that MAC. You posted about it in January. You were running
it with iwd. Why is systemd-udevd trying to rename the interface?
Do you still have the file:

$ cat /lib/systemd/network/80-iwd.link
[Match]
Type=wlan

[Link]
NamePolicy=keep kernel      ←←←←←←←←←
$ 

or your own version under /etc?

Or has the upgrade tried to revert the system back to a more
conventional ifupdown/wpa configuration in some way?

Hi, David, and thanks a lot for your help!

Literally means:

$ sudo apt-get update && sudo apt-get dist-upgrade

Afterwards:

$ sudo apt-get autoclean && sudo apt-get autoremove

This is what I do normally.

Indeed^2.

Have no idea. Maybe I did something in an improper fashion...
In fact, can't recall touching nothing about systemd-udevd.
Should I?

I still have the file:

```
$ cat /lib/systemd/network/80-iwd.link
[Match]
Type=wlan

[Link]
NamePolicy=keep kernel
```

And in /etc I only found:

$ sudo ls -aR /etc/ | grep iwd
iwd
/etc/iwd:
iwd.service

But nothing I remember to have created (at least manually).

Maybe, that's one of the things I'm trying to rule out/discard,
but can't think/know of a way to check it.

If the USB-port makes an unstable contact, could that connect/
/disconnect make the system assign new name to the dongle in
each iteration? (Just an idea...)

It has not happened again since the last occurrence, couple of
hours ago.

I don't think that's the main issue. But see below.

I suppose so. That would presumably be done by the kernel and
USB driver. I have flaky USB (and HDMI, and power) ports on
one laptop. The power cable has to be tucked under it so that
it imparts a torque to maintain contact (the battery is shot).
The HDMI doesn't matter too much; I just wiggle it.

For USB sticks, I use an extension cable, also tucked underneath,
but not imparting any torque. It just means the inboard end of
the cable doesn't move when I connect and disconnect things at
the outboard end.

That might work for a wifi dongle; after all, some people have
to use a socket extender to improve the radio signal behaviour.

Some time ago I read about iwd on their blog, and it talked about
the redundancy of interface names when using the index instead.
Or something like that. But memory is hazy as I didn't understand
a lot of it, and the context.

I thought the .link file should prevent all the renaming, as it
uses a wildcard match. But I don't have any experience of this,
nor can I replicate it as using the rfkill switch would not be
a comparable operation. (I have a dongle that used to work with
ndiswrapper, but I think that's gone since 5.x kernels came in.)

I know your configuration is a little more complex (hybrid) than
mine, as you posted it here a few months ago. You were using:

  allow-hotplug wlan4
  iface wlan4 inet dhcp

if your /e/n/i file rather than using iwd's built-in DHCP client.
I wonder whether some of the problem is caused by hotplug being
fooled by the reconnection into trying to redo the DHCP, which
could cause the old lease to be "stopped" (I don't know the jargon).

Is it possible that iwd could sail through the interruptions,
perhaps even /because/ it locks onto the index/interface name,
but for the hotplug actions screwing things up. I don't know.

As for my configuration, I've now settled on iwd+openresolv,
controlled by systemd-networkd/systemd-resolved. Perhaps it's
time I reposted it. Not that it will solve your underlying
connection problem, unfortunately.

Cheers,
David.
