Suddenly lost my network

[rogenerc]

About a month ago I was streaming to my Blu-ray player through a power line adaptor when I lost my internet connection. I checked my phone and noticed that I had lost Wi-Fi as well. I unplugged my modem and router and then plugged them both back in a half minute later. They each booted normally, but I still didn’t have internet. I hopped on my PC noticed it was connected to an “Unidentified Network.” When I used the Windows Network Repair, I received the message that my LAN doesn’t have a valid IP configuration. I bypassed the router and plugged my modem directly to the PC and had instant internet access. I emailed TP-Link for support on the router and went back and forth with them for a few days before they decided that the router was malfunctioning and started the RMA process. On Tuesday, the TP-Link router finally arrived and I plugged everything in expecting my network to come right back to life, but instead encountered the exact same issues. I still couldn’t ping the router and Windows stills said the LAN didn’t have a valid IP configuration. I decided it must be TP-Link sending out faulty equipment and ordered a new Asus router which arrived last night. When I plugged everything in to the Asus router, I was astounded to find the exact same issue still exists. I can’t even run the setup software included with the router, because I get a message that it can’t detect an ethernet cable. I tried connecting to each of the new routers through another PC and then again through a laptop, but with the exact same results. I would have sworn the router was the issue, but now I’m on the third router and I’m really doubting it. Any assistance will be appreciated.

I would deduce that this is actually an issue with your modem (due to the fact that your modem is passing down what you need to your routers, and you've replaced the router numerous times already) and that perhaps there is an issue with the scope of IPs your modem is giving you? If that is true, you would need to talk to your ISPs about it.

I would have them trouble-shoot your modem first and then ask about the IP scope.

Thank you, thank you! The ISP did their whole trouble shoot routine and said the modem was perfect, but I made them change it anyway. New modem is installed and network is back up. You just solved a month long head ache.
