Hey guys,
I have a pretty annoying problem and I can't solve it. I'm using a powerline and sometimes it disconnects randomly. When I try to let Windows solve the problem, it says "Default gateway not found". I've tried everyting that I've found on the internet. I used another cable, updated the Realtek PCIe GBE Family Controller drivers (both manually and automatically). I also tried to download drivers from the Realtek site itself, but that didn't work either. Fortunately, I can also use Wi-Fi, but this is way too slow, and, what my biggest problem is, it makes me disconnect from online games.

In order to troubleshoot this, you have to understand your house's electricity.

Powerline works best (1)on the same electrical circuit, (2)on the same electrical phase, and sometimes the circuit you are on has got too much noise.

If I were doing this, go to the main electrical junction box and find out, by shutting down one breaker at a time, what circuit (outlets) does that particular breaker controls. If you have a standard U.S. electrical junction box, with breakers, you will immediately see 3 very thick cables coming into the box, the middle one is ground, and the two others are the other 2 legs of a 3-phase system, you will notice, for the most part, the phases are divided left and right, so ideally you want both of your Powerline adapters to be on the "same side" of that phase.

Careful, if you are not comfortable with electricity.

My brother uses the powerline aswell (we got a 'family set'). And I didn't have problems before, only the last two days. So I'm pretty sure that's not the problem. Any other ideas?

You can either try to fix the current situation by looking for problems on the power lines as suggested or assume the adapter is faulty and replace it. There are really no other options for intermittent service on powerline adapters. It is easier to replace but potentially cheaper to search for a problem in your home. If you buy, do so from a store with customer friendly return policy in case that isn't the issue.

Just a couple of suggestions:

Ensure all powerline adapters are plugged directly into the wall outlets and not into power strips /surge protectors.

Check the status lights on the adapters when you encounter the problem. There are usually 3 indicating lights...Power, Link, and Ethernet activity. The Link light should be steady on (check the owner's manual for your particular adapter).

Also check the Ethernet lights on both the adapter and your PC.

The problem could be caused by another appliance / device / circuit in your home that has become noisy or faulty. May be hard to diagnose but you may want to check any suspect equipment.

Try swapping adapters to see if the problem moves. That should indicate if the adapter or circuit is causing the problem.
