That's my answer to your title question.
Diving into your post I see you have discovered or rediscovered what everyone has about 5GHz range. It drops off faster. Why? Physics. I can't fit a paper here.
As to the second question of WAP or powerline, models would change the results so go with which you can afford.
To me there's no advantage of 2.4 or 5GHz. I use which works best in the setup or location.
Hello, the internet is a lot better on 5 ghz in my household, and the thing is, i can't connect to the 5 ghz from my bedroom. Is it possible to pull a cable from the original router and create an access point in my bedroom, and if yes, will it get slowed down? (i probably have to plug a 25 meter cable on the primary router)
Well the question is, is can you have a WAP with 5ghz connection, and also will this be faster than a powerline extender? I've tried a wifi-extender and im currently using a powerline extender, however i go from 130 mbps to 30. What is the best way to extend this internet from one side of the room to the other.
Or shall i extend the ethernet cable and setup the router somewhere else and use 2.4 ghz?
Please help me, im in desperate need for it.
