My PC's wireless connection is working just fine. However, my wired connection stopped working. I only have the wifi connection in case my wired connection goes down, and I never have both enabled simultaneously. I can sometimes get the exclamation mark signifying limited connectivity but I can't get into the router or access the Internet. I set the IP to automatic, and I also tried my usual manual configurations but they no longer work. I keep getting the dreaded "no internet access/unidentified network" Windows message. I've also received an "improper network configuration" error from Windows.

I'm using a TM-AC1900 router. My modem is a Ubee U10C035.30 DOCSIS 3.0. Connected devices are two PCs, 1 laptop, a PS4, 2 Xboxes, 3 tablets, 2 phones, and a TV. Only about five devices are actually connected at any given time. No NAS or servers are connected. I have a wireless USB stick on my PC, in addition to its internal motherboard wired connection. My ISP is Comcast.
