 Posted: Fri Oct 11, 2019 10:43 am Post subject: Not getting IPv4 on boot |
 |
|
Booting Gentoo, both my fixed ethernet and wifi are started using hotplug.
Ethernet is not connected, so gets in state 'down'. That is correct.
Wifi sets up a connection using dhcpcd. When I log in, I see that the interface received from the ISP modem an IPv6 address, but no IPv4.
I need to remark that openrc shows a lot of services 'waiting for network (xxx seconds), probably until the wifi gets its address.

That means that I have internet access (I can ping google), but cannot ping other PCs on the network that do have an IPv4 address.
When I manually restart: rc-servicehttps://pastebin.com/W2XwTnKT net.wlp4s0 restart, I get both IPv4 and IPv6, and have access to my lan.

This is dmesg until I have manually restarted https://pastebin.com/W2XwTnKT

Clearly there is a difference between what is happening at boot and what happens when I restart wifi. I have no idea what or why. |

i had no problems with dhcpcd yet. what version are you using? what happens if you force -4 via dhcpcd.config?
could be a problem of the router.
also what is hotplug?
