My network is sometimes up and sometimes down. I use a wired connection. Sometimes it is up when i first start my computer. Another time it is down. Most of the time it will be up than when i restart the computer. Sometimes when it is up when i start the computer for the first time, it is down when i reboot.
This is the nic card i use: 02:09.0 Ethernet controller: Marvell Technology Group Ltd. 88E8001 Gigabit Ethernet Controller (rev 13)
I use dhcp.
