Will Powerline adapters help me to overcome gaming lag when other people are streaming video

home-networkingnetworkingpowerline-networkingwireless-networkingwireless-router

People in my household love watching Hulu and Amazon streaming video. The internet works if one person is watching but as soon as two do it goes to crap. Meanwhile, it shoots up my ping to 500 + as soon as someone starts watching in CS:GO.

I can't be wired to the modem due to the house configuration.

My computer (a desktop) is connected through wireless right now. Would a powerline adapter help to reduce my gaming lag?

Do note that I have the "Performance" tier internet from Comcast and at this time it is not my interest to upgrade it, as I don't know whether or not the videos will suck up even more bandwidth.

Help is appreciated, and if you have any questions just leave a comment.

Thank you.

Have a look whether your modem supports QoS to set limits on bandwith usage for each user. Here is a link that should get you going:

Depending on what modem you are using, you could flash it's memory and use Gargoyle or DD-WRT.

Here's the link to Gargoyle: https://www.gargoyle-router.com/
