Suddenly no internet connection?

[brianosaur]

W7 PC suddenly has internet connection issues.
It is LAN hardwired via switch to router.
Another pc on LAN has no connection issues. Other wifi devices have no connection issues.

Tried rebooting pc, modem and router several times.
Ran registry, malware, spyware, virus scanner/cleaners.
Unplugged/replugged ethernet cable and mb rpc shows a yellow light at the RJ-45 port.
Uninstalled ethernet card via device manager and let W7 auto reinstall upon reboot.
Booted W7 in "safe-mode with networking" and still no dice.

Any suggestions?

Can you be more specific about "connection issues" as that could many things.

Is problem constant or intermittent?
Do you get an error message?
Is it showing cable disconnected on taskbar?
Is the problem only with internet but you can access network shares or network printers just fine?
Can you go to some websites and not others, or some applications can get internet and not others, etc?

Try removing the NIC from device manager the refresh the device list to redetect it.

Constant

Do you get an error message?
No

Is it showing cable disconnected on taskbar?
Yes

None works. Cant see or share with PC from my other PC anymore in HOME network LAN

Can you go to some websites and not others, or some applications can get internet and not others, etc?
No websites. Nothing Connects (ie. windows update nor email)

Try removing the NIC from device manager the refresh the device list to redetect it.

Do you mean: Uninstalled ethernet card via device manager and let W7 auto reinstall upon reboot?

Do you get an ip address? You need to start your trouble shooting there...

I ran ipconfig in command prompt and got an address in IPv4 and IPv6

You are not receiving an IP address from your router. Please make sure your NIC is set to automatically receive an address from the DHCP server under its IP v4 settings.

That or bad router or bad cable.

Do you mean this?
(It was set to auto already)

 

[reedo_43]

can you ping 127.0.0.1?

 

[brianosaur]

can you ping 127.0.0.1?

Yes.
4 packets sent/received. 0 lost.

 

[bazzarooney]

So you can ping your loopback address 127.0.0.1 so your IP stack works, try connecting to your router with a different cable.
