[SOLVED] Ethernet disconnecting nonstop

[ttreyy]

I have searched a lot of places for a solution but never found anything that worked. I use a Trendnet Powerline Adapter (I’ve had it for over a year now and no problems whatsoever, it was my best purchase for my setup) but recently I’ve been having issues regarding the Ethernet cable. It cuts out for several minutes and will randomly come back in and stay on for another x amount of minutes then disconnect.

When it disconnects, the light that indicates that it’s on will flash once and I’ll go on limited to the X on the network in the bottom right. This happens multiple times while disconnected, and then will randomly connect.

I went to Walmart and bought a long cable to have it plugged into a different wall outlet, but same outcome. What is the issue here? Will I need a new mobo or perhaps a new powerline adapter? (I’ve flip flopped each one connecting to the modem and they both work, but the light on the one connected to my pc shows it’s not recognizing anything is connected) Any suggestions will be awesome.

The problem could be the powerline adapter but there are other things to check.

Wall outlet? Do you mean an Ethernet wall outlet?

Intermittent connection losses are likely a loose connection somewhere.

What does your network look like? Here is a basic line diagram to start with:

ISP ---cable--->Modem ---Ethernet --->[WAN] Router [LAN] ---Ethernet---> Powerline adapter ===wiring===> Powerline adapter ---Ethernet ---> Computer and Router Wireless> wireless devices.

However if two different wall outlets show losses then the problem is further back moving towards router and modem. I.e., some common point.

Ethernet wall outlets are notorious for developing a loose connection. Only takes one wire to cause problems. Simple pushing (re-punching) the wire back into place may solve the problem.

Key is to locate the problem by methodical testing as much as you and eliminate possiblities.

Use known working Ethernet cables and swap in for existing cables. Discover what works and where.

What is printed on the ethernet cable you purchased from Walmart?

Use your own network sketch to layout the design and keep track of what you change and try.

Hopefully not a motherboard problem.

However, do update your post to include full system hardware specs and OS.

Also include make and model information for your modem and/or router.

You probably need to move the modem end closer to your PC...I know that kind of defeats the purpose of the powerline adapters.

The reality is they may or may not work depending on the quality of your in home power wiring and outlets, the distance from the PC to the modem, and how many and what type of appliances might be between you and the modem.

Since there are a lot of variables in there that may impact the ability to connect through the house powerlines my suggestion would be to replace the powerline setup with a wireless router...the newer routers don't suffer from lag anywhere nearly as bad as older ones did and the connection and setup is much easier.
