Ethernet doesn't have a valid IP, wifi still works?

[concord72]

Running Win 8.1 on Lenovo Y410p. Verizon FIOS router, Actiontec MI424WR (Actiontec[1] ).
Everything was running fine until last night. No internet when I connected to the router with an ethernet cable, but the wifi still works. I ran windows troubleshooting diagnostic and it said ETHERNET DOESN'T HAVE A VALID IP. Restarted my laptop and the router, changed ports, got a new ethernet cable, tried hooking up another laptop, still nothing. It shows up as Unidentified Network with No Internet Access. Xbox is also connected to router via ethernet, that isn't working either. The wifi is working but it's shoddy, every few minutes it'll lag, Chrome will go into NOT RESPONDING mode for a second or 2 and then go back to working. Wifi is also prone to dropping out and coming back at times.
Please advise.

Power cycle your ISP Modem, router and computer(s).

Power all off
Remove power from modem and router for 30 seconds or so.
Connect power to modem, wait for it to finish booting and stabilize
Connect power to router, wait for it to finish booting and stabilize
Power up computer with Ethernet cable already connected

If still not working: collect IP configuration information as follows:

Open a Elevated Command Prompt:

Press WIN + X to open Start context menu.
Select Command Prompt (Admin)​.

Paste the following into the Command Prompt window, exactly as shown, including double quotes:

cmd /c "ipconfig /all > postme.txt & ping yahoo.com >> postme.txt & reg query "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings" | find /i "proxy" >> postme.txt & notepad postme.txt & del postme.txt"

and press ENTER.

A file will open in Notepad. Please copy and paste the contents here. Close the Notepad window and the file will be deleted and the Command Prompt window will also close. Paste the information in a reply here.

Did you power cycle things as I showed, especially the ISP Modem? That usually fixes problems like this, especially when Wireless works and Ethernet doesn't.

 

[concord72]

Just did a power cycle, still nothing.

Just did a power cycle, still nothing.

When you are only connected to ethernet, can you ping 8.8.8.8 or google.com? Can you try and report back? I also think following the above instructions is a good idea as well.

You need a new router then. Contact Verizon and have them replace it.
