Ping127 0 0 1 and Ping local address, Ping, the default gateway can be connected, but there is no ne

Of course, you can ping the internal network and the local IP gateway, but you need to ping the external network, and check whether there is a problem with the optical modem and whether it reports an optical fiber signal error lamp.

1. The other party's shutdown IP does not exist.

2. The network segment is different, and it cannot be found through routing.

3. The firewall settings filter the ICMP packets sent by ping, resulting in no feedback and time out.

4. The IP address is set incorrectly, for servers with multiple network cards, the IP configuration of each network port must not be in the same network segment, otherwise it will cause the route to not know which exit to choose.

5. Network cable failure.

6. The gateway is not set, which is for the 128 network segment of the small network, if the router is not configured, it will not be routed.

This may be due to the router not being properly configured, please check if the IP address, subnet mask, default gateway, and DNS server settings of the router are correct.

1.I started thinking it was a broken network cable.,Try it with a book 1.,The situation is still the same Can't ping the gateway and the telecom's ping can't it.,I don't know anything else.),

2.But this book 2 is all normal,(Is it the same network cable?) ）

3.Book 1It's normal to surf the Internet in other places.。 (Explain that the hardware is fine).

1.There is a problem with your book 1 setting, DNS gateway, or IP setting.

2.Cable. 3.The gateway, that is, the router, has settings!

lz said this.,Now it's clear.,I think the problem is in book 1.,It's very likely.,1.I started thinking it was a broken network cable.,Try it with a book.,The situation is still the same Can't ping the gateway and telecommunications.,Book2 can ping.).

2.But this book 2 is all normal,(The same network cable,Means the network cable is fine)

3.Book 1It's normal to surf the Internet in other places.。 (Explain that the hardware is fine).

4.After the book 1 of the IP,DNS,Gateway,Set up all the same as the book 2,Still can't access the Internet。 There are no restrictions in the route settings, and the route should be fine.

Go back and try the ribs to change the transmission mode, but the transmission mode is automatically adapted, can't it be used?

The transfer mode shouldn't be the problem, the problem:

1.Is it pressed on the book 1 anti-ARP software,Such as 360 firewall,Color shadow,Jinshan,And other anti-ARP firewalls! If so, please reset the options on the time side, do not bond the gateway, which can be very small.

2.There is a problem with the network card, there is a problem with the driver installation, and the most suitable driver cannot be found. If you use ghost, it's more likely, so please get off it and re-install it.

3.This is the last question I thought about, viruses. This is a problem that our technical group has discussed before, I heard (I heard from them, I also encountered it once, no matter what, I can't get on the network, ping can't get through the gateway, even if it's reinstalled, it's only a while, it's not good, the last grid disk.

It's just that I heard that there is such a poison.,I don't know if it's this when I encountered it.,I don't know.,You better reinstall the system.,I hope you're better than me! (You know why!) ）

I can't help you.

It is estimated that it is a problem with the transmission mode, see that you should know a little about the computer, enter the device manager, call up the properties of the network card, and then change the transmission mode to 10m half-duplex full-duplex, 100m half-duplex full-duplex try to estimate it.

Software Setup Problems Non-Hardware Problems Maybe Somewhere It's Blocked Reinstall the System Restore! Absolutely!
