Unable to connect to Ethereum main network

1. Network is not good, you log in again to see, if still not, you can try to restart the phone.

2. There is no problem at all, but relatively speaking, we must buy some reliable ones, because we must pay attention to them.

3. All wireless cat No.2 with 4 ports can't be used. Even if you use it temporarily, it will be broken soon.

4. The description is not very clear
I don't understand your purpose

eth0 is the device name. Eh0 is connected to an Ethernet network

if you mean you can't connect to the Internet
it depends on the network condition of your home
if you want to use PPOE, you can click on the link to change the configuration of the linked device, and you need to enter the password you set at the time of installation. Then add PPOE

5.

See the article:

6. Just set IP to get it automatically
VI / etc / sysconfig / network scripts / ifcfg-eth0
change bootproto = static to bootproto = DHCP

7. Let me tell you the steps. First of all, make sure your hardware connection is OK
1. Make sure the eth0 status is up, sudo ifconfig eth0 up
2. Configure IP, sudo ifconfig eth0 x.x.x
3. Add default gw x.x.x (your route)
4. Set DNS, edit / etc / resolv.conf file, and change the content to nameserver x.x.x.x
5 Restart the network instead of restarting the machine. Sudo / etc / init.d/networking restart

if you are in FC environment, you may be prompted that ifconfig cannot be found, just change to / SBIN / ifconfig

8.

The CentOS network card cannot be connected to the Internet. The ethtool displays link detected: no speed: unknown! Duplex: Unknown! ( The solution is:

1. Edit the virtual machine

9. Are you in the same network segment with Tianrongxin? You can try to log in with the IP of another port. Is eth2 port disabled for you.

10. According to my understanding, you should connect the broadband cable to lan1 port. There won't be a net in other ports. Connect the home broadband to lan1 port. Then pull out another network cable from lan2 port and connect it to the computer. Try it.
