Bad WiFi driving you crazy, during these stuck-at-home times?
Me too! This article at the bottom of the text here, covers a lot of stuff, but one thing took me 10 minutes, and tilting my router, to fix the bad spots in my house!
A router, like mine there, radiates around itself, like a radar scope on an aircraft carrier. A big flat circle around the router.
If you have antennas on yours, they radiate around the vertical antenna. (NOT straight above it like a rifle)
So behind my router, my kitchen, was fine. Also fine was in front of it, my living room. Even my bedroom, in front and above the living room, was good. But my office, off to the right and above the router... sucked! So I put that roll of tape under the side of my router, to 'tilt' the plane that the router was radiating, so it covered towards my office TOO. WHAT a DIFFERENCE! The signal became 2-3 times better in my office and even better in my bedroom! But since I only lifted the side of the router, the plane still went towards my kitchen and living room, so they stayed great.
How did I test this? I use 2 things on my phone, to make it like a Star Trek Tricorder:
WiFi Analyzer is like a Geiger Counter for WiFi. I use it to see what networks are in the air around a customer's place, their strengths in each spot around the house and what other networks may be interfering with the signal. You can see from the photo in the comments, my network, Missing-Pieces, is the strongest, since its the nearest. As I go around the house, like Spock 'analyzing', I could see everywhere was around -45/-60 decibels (smaller is better) for 2.4 and 5.0 networks, except for in my office. After tilting, everyone was up in that range!
[Another thing you'll notice from the photo is missing-Pieces is set all by its lonesome on channel 8. This gives me a clearer/stronger signal with no interference from my neighbors routers and you can see there's a LOT of them, all centered on their carrier's defaults of channels 3, 6 & 11. I went into my router, after looking at WiFi Analyzer, and picked a channel no one else was using, 8. You can see from the other pic that I did the same on the 5mhz band, choosing 38 over the SUPER crowded 42. This alone gives me much better WiFi than my neighbors.]
With SpeedTest, I determined what download and upload speeds I was getting. The article mentions 10mbps download and 5mbps are good. I was getting on avg 20 and 5.5 around my place, but only 5 and 4 in my office! After tilting my router, everyplace is now up around 20 and 5.6! To further test, SpeedTest is available online for PCs and Macs too, so I'll be sure to test my speeds on the machines too. But I wanted an even comparison around the house, so I used my phone posed in front of each of my PCs and Rokus and ran SpeedTest and got numbers I could reliably compare.
So with just a few minutes and a crude adjustment to my router, I have MUCH better WiFi around my place!
