Modem: Cisco DPC3825
Router: Linksys 3200
Powerline: Netgear xe102 (v1)
ISP: Shaw [Canadian] (50mbps down / 5mbps down)
Devices connected to router at any given time: 10-20

Hello,

After trying every possible form of troubleshooting that I could think of and/or Google, I am turning to this forum for some advice. I am currently experiencing issues with my home's network that has started in the last 6 months and has slowly deteriorated over time. Speed decreasing and fluctuating signals throughout the house.

I am aware that there are severe dead zones in my house and one of the things I tried to do is set up a powerline connection to my basement. My router, modem, and a powerline adapter connected to the router are located in my office on the main floor of the house on the opposite side of the basement room that I am trying to connect to. We have concrete floors and lots of hot water piping that interferes with the signal. As it stands at the moment, my router can pipe to the basement about 2mbps down and 0.5 up at max with lots of signal drop. I thought the best solution would be to plug in a powerline adapter to get a more direct/stronger signal to my basement, but I still only get roughly 2mbps down and 3 up. So I went to check the signal coming out of my router in the same port with the same cord to my laptop and I was getting upwards of 50mbps down and roughly 3.5 down. I tried all 4 Ethernet ports on my router with 3 different Ethernet cords and still only 2mbps down through the powerline. So I went to try a different power socket, one in the same room as the router and I was only able reach speeds of around 24mbps down.

Now, my router has a weak signal, I do not know if this is due to it not being a very good router or if it is that my house is where signals go to die. In the same room sitting next to the router (on a laptop) I get a steady 40-45mbps down. If I were to walk merely just outside of the room I lose over 50% of the signal. If I go one room further, the speeds are getting into low single digit mbps territory. And the signal is never steady. It can go from 20mbps to 1mbps in seconds. and stay in each state respectively for long periods of time. During these fluctuations of signal there is no extra throttling, interference, or devices straining the router.

My main goal of asking for help here is to setup a stable connection to my basement (dead zone) as I would like to turn the room into an entertainment room with game consoles and a media PC.

Any thoughts on what the weak link(s) in my network are and what I can do to improve it are much appreciated! (bonus points for recommending specific hardware to replace the weak link(s) as I have no clue to what is considered a good product when it comes to networking.

Thanks in advance, Mike

Are the powerline adapters plugged directly into the wall outlet and not a power strip or surge protector?

Understanding that you have concrete floors, but any way at all to run a Cat5 cable down to the basement? A cable would guarantee a solid connection.

If there are any nearby coax outlets, you might strongly consider MoCA adapters.

Both ends of the adapters are plugged directly into a wall outlet.
Running a cat5 is not an option considering that the room is a floor below and on the opposite side of the house. (it is quite a distance too)
And yes, there is a coax that runs to my dvr cable box.
If I were to purchase a MoCa adapter, would I need to have a second router to make that signal wireless for the rest of the room? and would I need to split the signal to share it with my dvr cable box?

While some MoCA devices have a wireless router incorporated, I'd recommend using your own router attached to the adapter since there are far fewer MoCA routers from which to choose.

Some MoCA adapters have a second port that allows you to route the signal through to the DVR cable box, so a splitter wouldn't be necessary.

Thanks for all your help and for being quick to respond. I will be looking further into using a MoCa adapter as a solution.

Troubleshooting wireless issues can always be tricky because there are many things that can interfere with signal propagation and radio waves don't always act the way you think they would. One way to start addressing the issue is to use a program to create a WiFi "heat map" of signal strength. There are several that you could use but I haven't seen a fully functioning free one. One program you may try is the home version of Inssider. That will at least tell you what signals in the 2.4 / 5 Ghz band are transmitting in your area. It will also give you an idea if you need to switch channels because of band saturation. If you are operating on the 2.4 Ghz band you'll want to be either on 1, 6, or 11. Also Inssider will give you signal strength to the AP. Assuming you load it onto a laptop then walk around your home. As a general rule you want a signal strength of -65Decible or better ( so that's actually -64, -63, etc.).

Also, you may need a better antenna for the WAP if you can interchange them. Most of them come with an omnidirectional one which broadcasts mainly on the horizontal plane with limited elevation/declination. You may try a directional antenna. Or you may just need a WiFi extender to plug into your basement. Netgear and other companies make different models for relatively cheap.
