I am experiencing weird network problems with a MacMini 2018.
At my home, I am connected through Wifi: No Problem.
In a different house, I try to connect via Wifi, "impossible to connect". And it's OK with a laptop for the same Wifi endpoint. I verified the password several times. Same result with the Wifi created by my iPhone SE.
I try with an Ethernet cable which was used by a desktop computer. The MacMini get an IP but when I try to connect on a website I've got timeouts, no online service works (this ethernet cable is connected via CPL).
The only thing that works is when I connect an Ethernet cable directly on the internet box. This time, I've got an IP and everything works as expected.
Any hint to point me on what could be wrong?
- Can't connect on a new wifi network, this wifi is OK on a laptop
- Can't connect with ethernet with the same cable used by a desktop where everything works
- OK only when connecting directly on the internet box via ethernet.
A ping when I am connected with the non working ethernet:
PING yahoo.fr (22.214.171.124): 56 data bytes ping: sendto: No route to host Request timeout for icmp_seq 2
One thing I noticed: on my laptop I see a lot of Wifi (of the building, more than 20 but on the MacMini I only see a few.
Edit: I don't know why but everything works now. I have deleted the "Wifi" entry in the parameter > network setting. Then I have recreated it, it may have helped, but I can't be sure.
