Warning: Most of this post is about a moron trying to set up his Internet, so if you don't want to waste your time, just read the tl;dr version.
tl;dr: Use Ethernet unless Wifi is your only choice.
For the past 8 years my PC and laptop both ran on Wifi, until one day the landlord decided to kick me out of his house. After a while I found a better place and moved, but there was a problem: the Internet.
Before moving, I got my Wifi router in my room fetching all devices I have: a desktop PC, a laptop, a phone and a tablet. Since the router is wired from the landlord's router, the speed was decent enough, usually 40-60mbps, and there was only a few problems:
- Router sometimes lost Internet and kicked all devices for like 3 times a week to 3 times a day.
- Teleporting in Street Fighter V online matches was normal.
- Working from home through Windows Remote Desktop was a nightmare with up to 15 seconds delay for every action.
After I moved, things didn't go easy for my Internet. This is how it was at first:
The distance from the PC to the landlord's router was like 5m, and there's a steel door in-between, making the signal a lot worse than standing next to the router (tested with my phone and got like 70mbps). Even with my old router acting as a repeater, I didn't get anything close to 20mbps.
After asking around, I decided to get a better router to see if I could get any better Internet. I ended up ordering an Asuck RT-AC68U since I heard it's very reliable.
The order took a few days to ship. After the router arrived, I placed it inside the room and used it as another Wifi repeater, and I did see a small improvement. Compared to my TPLink WR841N, the Asuck router provided stronger signal for my laptop (36-45mbps):
The PC meanwhile wasn't lucky:
Above was the best I could get for the PC. I tried various configurations and got even worse results, so I had to use my laptop as a Wifi hotspot for my PC.
After that, I tried moving the Asuck router outside, right next to the landlord's router, wired from it. The result was overall better but still not much:
