Internet Speed drop unexpectedly

[manesag]

Hello,

As a forewarning I didn't know if to put this under troubleshooting or network because it could go under either.

Anyways, we have Comcast internet and the internet is usually great, 25+ MBPS download, 5-7 MBPS upload and very small ping. Now my computer is far away from where the router is so there is a power line adapter sending the fast internet over to my computer. The Router is a D Link DIR 615 and the power line adapter is a Trendnet TPL 303e. Now this has been working for about 6-7+ months without any problems at all. Now around 2 weeks ago we had a washer changed out for a newer one because the old one broke. But, the following week (last Saturday) a few strange problems occurred. First while I was using the internet, the internet on my desktop disconnected (windows 7 showed the little monitor with a yellow triangle). After about an hour I finally thought of restarting it and when I did my internet was fine. But I did notice a small drop in speed. Now when Sunday came along my speed was down to about 2 MBPS on download, BUT!, my ping and upload stayed normal. So fast forward to today, I have checked the speed of my end of the power line with my laptop and got similar speeds, checked it with another power line located in a different room, same results. I have tried different cables on my end, So that eliminates the power line and its cable at my end. I then moved my power line adapter to the same room as the router (its about 3 feet away from where the router is located at) and did a speed test and got around 15-20 MBPS. That eliminates the factor of the other power line adapter being broken. So what I think it is, is that the wiring in the house is causing that. But the only thing that we got new was the washer but if thats the cause it would have started affecting it the day we got it hooked up.

Just to clear something up before anyone else comes back with a response, do you actually mean MB (megabytes) per second, or Mb (megabits) per second? I'm assuming you meant megabits because 25MB/s is an insane internet connection, but we did have a guy on here before who actually did have a 15MB/s connection and everyone was working under the assumption that he meant megabits. Needless to say, caused some confusion.

1 megabyte = 8 megabits so it could make a difference if we start getting into the max throughput for powerlines etc.

To get back to the original question though, can you run an ethernet cable from the PC to the router? That would tell you whether or not it's the NIC in your PC. If it's the washer it'll only affect the network when it's actively drawing a current (i.e. only when it's turned on and washing something).

Yeah It is MB/s

Here is my fastest speed test directly on my desktop

That is Mb/s (megabit), not MB/s (megabyte).

Ohhh ok I am sorry

But do you think you know what I can do to fix my problem?

We'll I have figured out the problem.

I am assuming that something is wrong with a power line (the actual electric copper cable) in the attic.

This is because if I move my power line adapter to the room next to mine and run a cable to my desktop I get around 10 mb/s which is better then the 0.3-1 mb/s I got before.

The main reason that I assume this is the last two far rooms in my household (mine and master) have the performance degradation from the power line.
