So I recently upgraded my internet and I got my new modem today. So I set up everything and it all went well until I tried using my powerline adapters as the internet connection for my computer upstairs. The only reason I'm using a powerline adapter is because I am not able to fish an ethernet cable from the basement through the house.
I got the Rogers Ignite 100u package and when connecting directly to the router, I got the promised speeds of 100mbps down and 10 mbps up. However, when using the powerline adapters I was only able to get 25 mpbs down while the upload remained the exact same. My wireless connection varied quite a bit actually. (Also I should mention that the upload speed stayed pretty consistent for the most part, it's really just the download speed I'm worried about). So on my iPhone I was able to get around 40 - 47 for download. On my tablet, i was only able to get 5 mbps download and 8 mbps upload.
So what I'm trying to get at here is, has anyone else experienced a problem similar to this? And also why does the upload speed stay the same?
My powerline adapters are the TP-Link AV500 Nano Powerline Adapter Starter kit.
One last thing, the internet I upgraded from was 25mbps download and 2 mbps upload. The powerline adapters worked for my old modem but I'm not entirely sure it works for this one.
Welcome to the Community Forums 🙂
I've never used powerline adapters myself. I have always used another router as an access point via ethernet connection and they work perfectly since I am in a 3 story home. If your internet works fine without it, I am not sure what else to suggest to make the speeds better using the adapters.
How are you measuring the 25 Mb/s down? By that I mean, is one end of the adapter set downstairs with the modem and the other end upstairs connected via ethernet to a pc or laptop, or is the upstairs connection via wifi? Are your indicated wireless measurements via wifi with the modem, or with a router connected to the upstairs end of the adapter kit?
My personal opinion is that you might be at the mercy of the adapter kit and your home wiring. The first thing I would do is prove the data rates from the adapter kit over the shortest route possible, and that would be with both of them connected to an extension cord that has multiple outlets, or, failing that, within the same room on wall sockets that are as close as possible to each other. Try that, with the remote adapter connected to a laptop so that you are measuring connected rates only. That should be an interesting number. The adapter kit is supposedly rated for 500 Mb/s so, I would think that you would see the full 100 down, 10 up.
When that is done, move on to the following. Have a look at the electrical panel in the basement and determine what side of the panel that the modem and connected adapter are running on and what side of the panel the remote adapter is on. Ideally, if you were going to park the remote adapter anywhere, it should be on the same side of that panel. The complete communication path in that case is into one side of the panel via one of the room circuits, along the internal bus bars on that side of the panel, and then out to another room on the same side of the panel. If you are crossing over to the other side of the panel with those adapter locations, then your going outside of your home, out to the transformer and back on the other side of the panel. In doing so, you're probably subjecting that data stream to a fair amount of background noise and you will also see a drop in the received power at the remote adapter due to the roundtrip distance to the transformer and the resistance in the wire throughout that distance. Both of those will drop the data rates of the adapters. Its possible that there is a short path thru a 240 Volt circuit breaker to the other side of the panel, but I don't know how well the circuit breaker will conduct the higher frequency data signals. Your test with the extension cord should have shown what the adapters can do with a very short, next to nothing in terms of distance data path. So, have a look at the panel locations as they currently stand, and if the adapters are on different sides of the panel, try to find another room that will allow the remote adapter to remain on the modem's side of the panel. That will cut the length of the data path and reduce the noise that the data is subjected to.
If you look at the following pages, specifically the first circuit diagrams you can see the red and black circuits in the simplified panel diagram. Those represent the right and left side of the panel that sits in your basement. Hopefully, by looking at that you can see what I am referring to in terms of staying on the same side of the panel.
Why does the upload rate stay the same? Most likely because the data path length and noise along that path doesn't affect the rates in the 10 Mb/s range. The data rate is low enough that the adapters don't have any problems with the received signal levels or noise within the signals. Higher rates are problematic, so the adapters probably throttle back to a point where they can operate and not suffer high error rates.
Another point to consider is moving the modem to another location. If you have cable outlets elsewhere in the home, you can move the modem to any one of those outlets. From there, if you still wanted to use the adapters, perhaps that would result in a shorter data path between the two adapters and keep the data rate from dropping too much.
One adapter is connected in the basement next to the modem and the other one is 2 floors up in my room connected to my computer via the ethernet cable it came with.
So I also tested the rates of the adapters by plugging them downstairs in the same outlet next to my modem and the rates I was getting were pretty low. It was varying from 65 - 68, when I should've been getting 100 mbps. And I have not yet looked at the electrical in the basement yet but I will do that today and see if I notice anything.
I didn't expect to see the results that low, but not surprised at the same time. So, I had a quick look at the specs. TP-Link indicates that the devices will support 500 Mb/s. Only problem is, the ethernet ports are only 10/100 Mb/s, so at the maximum, you will only ever see 100 Mb/s. The fact that your seeing 60 to 65 Mb/s with them isn't terrible, but still not even up to the 100 Mb/s you should be seeing plugged into the same socket. If these are a recent purchase and you still can return them, I would do so and have a look for another set that has 10/100/1000 Mb/s ports and that will really run more than 100 Mb/s. Here's a link to a pdf doc for the adapters:
Just to confirm the indicated port speeds from the user manual, look at the back of the modem, specifically the connected port LED. If that LED is amber, then its connecting at 1 Gb/s with the device port. If the LED is green, that indicates that its connecting at 10/100 Mb/s. Note that the modem port can't tell if the speed restriction is from the port that its connecting to, or due to the ethenet cable. Some cables only support 100 Mb/s. Or, if the cable is damaged or not connecting properly at either end, then you aren't using the total wire set within the cable, and the ports therefore negotiate down to a level that they will communicate without issue.
On the laptop, right click on the internet symbol on the lower right hand side of the monitor and bring up the Network and Sharing Center. Select the Ethernet link which is located in the middle right hand side of the page. That will bring up the Ethernet Status panel. The Speed that is shown on that panel is the port to port or, device to device communication rate, not the internet download / upload rate.
Both of those will confirm or deny what the user manual indicates for the ports on the adapters.
Unfortunately this is the last day to return them and the store is closed however I am willing to spend a few dollars more for a better set of adapters. When I looked at the back of the modem, the light was flashing green not amber.
I also checked the speed with the laptop and it shows 100 mbps and I also tested it again on speedtest.net and only got 50 mbps.
So, unfortunately, the adapter ports are only 100 Mb/s. You're going to have to do a little research to find a set that has gigabit ports on them which will support speeds above 100 mb/s. That way, in theory, you might see 100 Mb/s between floors, provided that you are on the same side of the electrical panel for both the downstairs and upstairs wall sockets.
When you go into the store, just say, darn, I missed you guys by a couple of minutes yesterday. Will you still take these back on return? Never hurts to try.
Ah okay, well thank you so much for the help. I really appreciate that. I will search for better adapters and hope they will work better next time.
As for the electrical panel, the labels on it are really confusing and aren't really specific so I'm pretty sure I'll never be able to figure out if they're on the same side or not.
One more thing actually, do you recommend any other solutions? I'm open to anything beacause I really want to optimize my internet speed.
To figure out the circuit breakers its just a process of elimination. Turn the lights and appliances on all over the house, and then, flip a circuit breaker. Trundle upstairs and determine what is not on or running when that breaker is off. The larger breakers should be 240 volts breakers for the oven, stove and dryer. When you determine what that breaker does, trundle back downstairs, turn the first breaker back on and turn the next one off. Repeat the trundling until all room sockets and lights are matched with the breakers. When all is said and done, you will have accomplished two things, getting your exercise for the day, and determining what rooms match what circuit breakers. Miller time, so to speak, or whatever your favorite beverage happens to be.
I don't have specific recommendations for a powerline adapter, however I came across an interesting review which is two to three weeks old at this point and which is updated throughout the year:
Have a look at the review and look specifically at the upper table which contains adapters with the Homeplug AV2 MIMO standard. If I was shopping for a powerline adapter set, I would be looking at the Extollo, D-Link DH701AV and the ZyXEL, in that order. It might come down to a matter of, can you get any of those from stores close to where you live. There's always the online option if you are a little more patient for the adapters to arrive.
The one thing to remember is that your results, at the end of the day will be site dependant. The house electrical circuit distances and noise levels will really play a critical part in determining the end speeds with the adapters.
One other consideration, if you happen to have cable outlets that are available, is to use a MOCA adapter. I haven't done any reading on these, just bringing up the idea. Depending on your house cabling, these might be an option as well.
@Chris_Chan here is another reference for comparison. Have a look at page two of this CNET article, which contains a comparison chart for various adapters:
Okay, so I decided to completely drop the powerline adapter method because I was able to move my modem from downstairs, in the basement to the first floor, the main floor.
So before I continue, I will tell you my setup on the second floor, so the floor above the main one. So in my room I have 2 computers, one is newer but it does not have a wireless card and my powerline adapters weren't working that well. So instead, I used a wireless extender from netgear which I had before and I used that to connect to the same network and hardwired a ethernet connection from the extender to my computer. So now the speed is around 50 - 60 mbps download and 10-12 mpbs upload. Although the speed is decent I was hoping I would get at least 70 - 80 mbps download since I was getting around 120 mbps download when I directly plugged the router to my laptop.
So for my other computer which is around 5 or 6 years old,I tested the speeds and they were around 25 - 40 mbps download and 10mpbs upload.
So when I moved my router, my signal got better so that makes sense but the speed remained the same. I'm wondering if it has something to do with the coaxial cable that the modem is connected to or.....? Also, I live close to a police station if that changes anything, which probably doesn't. Also the cable coming from outside that is going into my house is connected to a 2 way splitter but I only have 1 cable connecting to it. Could I just use a coupler instead?
Basically, what I'm asking is do the cables make a difference for wireless speed & I guess... how do I fully take advantage of the AC modem?
If you dont have anything on the other side of the splitter, yes a coupler likely would do better, as you would not be getting any signal loss by the splitter then. (when you put a splitter in, it drops the signal level a bit on each split)
Other possibility, may be other interfearance? (other wifi signals or products on the same range interfearing)
As Gdkitty indicated you can switch the splitter for a barrel connector. Here is one that is available from Lowe's that will do the job;
These should also be used to replace the wallplate connectors as they are high frequency connectors which will support satellite and cable service.
You might still have to bite the bullet and buy a better powerline set to see high data rates upstairs. That wouldn't surprise me. The quality of the cable can affect the wifi data rates, but only by affecting the data rate for the modem as a whole. You would first see that in the wired data rates which would have to be very low as a result of poor cable performance. The follow on from that is reduced rates to wifi devices.
How do you take advantage of the ac modem? You would have to have wifi devices that support 802.11ac, which is the latest wifi standard to hit the market. The CGN3ACSMR supports 802.11ac. What I don't know at this point is whether that mode is exclusive, locking out anything running 802.11n, which is the common standard. Maybe someone using that modem can chime in here. In order to support both modes simultaneously the modem firmware would have to have an 802.11 n/ac setting, instead of an 802.11n and then 802.11ac, as is indicated in the CGN3V4 manual. So, thats not the manual that exactly matches the modem, but it doesn't indicate simultaneous mode support. So, at this point I'm not exactly sure whats available on that modem. If it has a combined n/ac mode, and you have devices which support 802.11n, and 802.11ac, the mode of choice by the device should automatically be 802.11ac. Anything else that only run 802.11n will use that mode to communicate with the modem. The modem should switch between both as required.
