Desperate to improve my 5GHZ connection. Help me decide whic

Ok so i just installed my "new ac router" but my 5ghz connection on the new router is noticeably worse (4 bars to 2-3) on 5ghz, Full bars on 2ghz, my network card is a centrino ultimate-n 6300, which i know isn't all that bad, first thing i want to know is if it would be worth buying an external usb wifi adapter like this

My last question is if i should just go full on pass throught powerline, direct to wall sockets.

i have heard lots of mixed things on powerlines resulting in people getting their mbps capped/low mpbs. I have a 50mbps connection, i stream via xbox app and my xbox one is wired, i just want to improve my 5ghz signal HELP PLSSad

doesn't travel far or well thru walls and furniture. Your only real solution is to move computer closer to the router or have a long USB cable to connect the USB wifi adapter and place it closer to router.

Powerline may work but is unreliable for long term connection. I have had powerline work fine for months. then disconnect for no obvious reason.

And NO, don't even think about wifi extenders! Those are even more glitchy than powerline for dependable connections.

Ever think about running a long Cat cable between ISP modem and your router so that router is in a more central location in your space?

I agree. In fact I've been flipping folk back to 2.4GHz to get more distance in some setups. It all varies with location and what else is in the area but go with what works.

same thing happened to me

a few years ago I got a dual band router and connected everything to 5ghz thinking since it is new, it would be the best. boy was I wrong. It only works on those devices that are close. anything further away and behind walls had problems. I had to go back to 2.4 on just about everything.
