USB wifi and Bluetooth dongles under GUIX

USB wifi and Bluetooth dongles under GUIX

On switching distros to GUIX a couple of weeks ago, I had what I guess 
is the not uncommon experience that my laptop's internal wifi and 
Bluetooth interfaces needed proprietary firmware and therefore wouldn't 
work with Linux-libre.  No problem, I thought: I bought USB wifi and 
Bluetooth dongles that were known Linux-libre-compatible.  I have three 
residual problems which I'm hoping the community can help with, please:

- The wifi connection drops with even the lightest of physical touches 
on the body of the dongle (Atheros AR9271), and because the dongle 
sticks out a long way from the laptop case, it gets touched a lot.  Has 
anyone had any joy with a Linux-libre-driven USB wifi dongle that 
doesn't have these properties?
- One or both of the dongles is frequently stopping the machine from 
resuming successfully from sleep.  I can find instructions online for 
how to configure systemd to handle awkward USB devices during 
sleep/wake; are there equivalent instructions for shepherd, please?
- I've tried following the instructions in the GUIX reference manual for 
how to configure the system to activate Bluetooth at boot time, but with 
no joy: I still have to activate Bluetooth manually after logging in to 
Gnome.  Any advice on this, please?

yes, but unfortunately I cannot suggest a particular brand. I have bought
a random, rather large and rather cheap external Atheros dongle years ago,
and it just works. I have even somewhat twisted the metal part of the USB
plug, and it still works.

dmesg says this:

I have tried bluetooth, but just enabling it in the service part of my
system definition did not make it work, and I was not motivated enough to
spend time debugging.

Similarly for the sleeping function.

Thanks.  Yep, 0cf3:9271 is the same model I've got.  It works, just a 
bit flaky and rather obtrusive.

I occasionally use a ~15 cm USB extender and then plug the wifi stick
into that. I've found that it's just long enough that I can tuck it
behind the screen where I'm less likely to tap it.
