Link aggregation

[corruption5.0]

so i recently learned about link aggregation and had a question about implementation. at home i have a consumer grade Xfinity router in its latest model and i am using a power line adapter to get a wired connection to my room since my house isn't wired. the power-line adapter has two Ethernet ports and i was wondering if i could get a switch that has LACP and connect two Ethernet cables to get better bandwidth. my only problem or doubt really is if it is possible to do this in any form or matter?

may be possible, but it wont do anything

power line isnt fast enough for it to matter

What would be the purpose?  Are you transferring files between other wired PCs in the house?  If not, I can pretty much guarantee that your internet speed is the bottleneck, so doing that would make no difference

 

Not to mention I don't believe that would work regardless; the powerline adapters are never quite up to the speed of what a single real cable can provide anyway (1 Gbit), so adding another and sending it through the powerline bottleneck would not help.

The limiting factor here would be the powerline adapter. A single cable supports more bandwidth than the adapter, so having two cables on a single adapter wouldn't help. Technically, having two powerline adapters setup and using the two connections from those in link aggregation could work, but it would depend on the location of the adapters. If you had two next to each other, then data would be going along the same lines, so the bandwidth limit associated with the powerline adapters would still be there. 

Do you perform many local file transfers that require more bandwidth? To be honest, it would be better to invest some money in running a cable directly from the router/switch to your PC. Either through the walls, on the outside of the walls or along skirting.

well i wanted to get the best bandwidth possible out of the power line to my PC i currently get 50megabits with one port but i have a down of 150 megabits from my ISP so i wanted to see if combining the ports i could get 100megabits instead of the 50 or something along those lines

Nope. It's not the ports that are limiting you, but the wiring in the walls (most likely). Having double the capable bandwidth at the end of a bottleneck doesn't alleviate said bottleneck. 

EDIT: A way to think of it could be this: 

If you have a gigabit switch and connect a cable capable of 100Mbps to the router, which has an incoming connection of 200Mbps. Now, connect a cable capable of 1Gbps to your PC and the switch. You're still only going to get 100Mbps of your 200Mbps connection, as the cable to the router only allows for that much. If you add another 1Gbps cable to your PC, then you have a theoretical bandwidth of 2Gbps between your PC and the switch. Still, you only have a 100Mbps connection to the router. The thing that would need changing is the cable connecting to the router (or in your case, the issue is the powerline adapters, or more precisely, the wiring in the house.)

Powerline connectors are usually slower than wired, but they are usually like 300 to 500 Mbit, not 50... something is horribly wrong

The quality of the connection depends on the wiring in the building, as well as the distance from the other adapter. Some people have better speeds over WiFi than powerline.

i completely agree because the one i got is a TP-Link TL-PA4010KIT AV500 which supports 500 megabits yet im only getting 50 at most

yes, hence the "something is horribly wrong"

 

I am concerned for the wiring in that building now...

yea not gonna lie the house is decently old and in some outlets i need to jiggle the cables to get them to power devices and some outlets just straight up don't work t all so I'm confident its the wiring but thanks for the help all

How old is the building? While age is not always a certain way to determine the quality of the wiring, old houses tend to have worse, or degraded wiring, resulting in slower speeds.

it was built in 1981 so its about 35 years old or so but its a town home

That should be fine... it would all be copper, modern codes (more or less), nothing unusual... Are there any other devices in the house that could be causing powerline interference?

major ones i can think of are just the fridge, washer and dryer and maybe the electric stove

I would suggest trying out two power outlets that are close to each other. If the speeds improve significantly, then it's almost certainly the wiring in the house. If it doesn't improve, it could well be an issue with the adapters, though it could still be that the wiring is bad. 

If you can, it's worth testing either another set of adapters, or your set in another building. It can help determine what the issue is.
