Hello everyone:

I have a peculiar problem that I can't figure out, I'm hoping someone 
will lend me a hand.

I'm running GuixSD, latest git pull on the Gluglug X200. Using wifi via 
commandline, wpa_supplicant, as I will demonstrate below. The usage is 
problemless on all wifi networks, even on the road, however I have a 
problem with my home wifi - which is a pain.

The problem is, it will connect, but then internet is inaccessible, I 
can't ping my gateway address. Every other computer and phone connects 
to the home wifi no prob. Also running Trisquel on the Gluglug, it will 
connect to the wifi no prob vie NetworkManager. If however I disconnect 
the NetworkManager in Trisquel and connect via wpa_supplicant using the 
same script as in Guix, I'm also unable to ping the gateway.

So something is wrong, but I don't see the problem. I can connect to and 
use any other network with wpa_supplicant, even connect to my phone's 
mobile hotspot, just not the home wifi. Can anybody help me figure this 
out?

So, in Guix SD, the working connection to my phone's hotspot:
