Cannot set TP-link TL-SG105 + Arris CM820 modem on Macs
My first post here, so hello to everybody, and TIA for any help!
I just bought a TP-link TL-SG105 switch
So, I plugged it to my Arris CM820 (I tried port 1, 4 and WAN)
Then I have connected my two macs to port (1,2,3,4 - I have tried all possible combinations)
One of the macs connects without problem. I see the IP of my provider, the Subnet Mask Address (255.255.240.0) and the router address (93.73.224.1)
But the other Mac does not, I get a message
“Ethernet has a self-assigned IP address and will not be able to connect to the Internet.”
With an IP address (169.xxx.xxx.xxx) a Subnet Mask address (255.255.0.0) and no address for the router
So, what should I do to get the switch to switch my internet connection???
(I am completely ignorant of connectivity and network issues, so use simple and detailed language to answer me :) )
