I have installed Ubuntu Server 20.04 on a Raspberry Pi 4 4GB model. It’s meant to be a media/file server for my parents.
I set everything up on it at my house and it works great.
However, when I hook it up at my parents, it simply will not get on the network. The only real difference between my house and my parents is the network.
I have tried multiple Ethernet cables.
If I ping anything, i get
Temporary failure resolving <hostname>.
On the router’s admin panel, I can see the Pi’s MAC address but hostname is blank.
ip route comes back empty.
I’ve tried plugging directly into the router and also through a switch into the router.
The other odd and possibly related thing is that the date on the Pi is always wrong there. When plugged in at my place, it gets the time fine through the network.
When plugged in at my parents, the date is stuck at the last time I had it on the network. I
set-ntp off and set the date manually and
set-ntp on again.
timedatectl1 reads this after that
<roughly correct time, since I manually set it> Time zone: <Correct time zone> System clock synchronized: no NTP service: active RTC in local TZ: no
I’m really at a loss at this point. The only difference is my router vs. my parents, and there doesn’t seem to be anything wrong with their router.
Please, does anybody know what else I may try to fix this issue?
