Wi-Fi Issues Can Be Difficult to Resolve

Wi-FiI’ve never been to any place that uses Wi-Fi for internet connections that hasn’t ever had issues. Even familiar Wi-Fi hotspots at places like McDonald’s and Starbucks can’t avoid them. Resolving certain issues is sometimes relatively easy to resolve. They can be extremely difficult to resolve at other times.

Wi-Fi Doesn’t Like Walls

It especially doesn’t like walls made of cement. There are four houses in my compound and all of them have cement walls. Some of the inside walls are made of cement, even though lighter materials would make more sense. Every interior wall in my house is made of cement, and it really makes no sense at all. I should have paid a lot more attention when it was being built.

I have one router connected to another so that one end of the compound can get a signal it wouldn’t otherwise receive. It was important when one of my in-laws set it up (while I was stuck in Hawaii) because all of my nieces and nephews were stay-at-home students due to the pandemic. It’s no longer important since they’re going to school again, but I’m not going to cut them off.

When I first returned home in March 2022, my wife (Josie) and I were staying in the second bedroom. It’s directly behind the master bedroom and directly across from the third bedroom. We had to sleep in that room until the air conditioner in the master bedroom got fixed. The main router is in the third bedroom.

My laptop computer only supports the 2.4 GHz frequency, while my Raspberry Pi 400 supports both the 2.4 and 5 GHz frequencies. Getting signals from the router in the third bedroom to my laptop computer and my Raspberry Pi 400 wasn’t an issue in the second bedroom. When we moved to the master bedroom, I discovered the 2.4 GHz frequency didn’t work well with either computer. Neither Josie nor I had any issues with our phones.

I could connect the Pi to the 5 GHz band, but I needed another solution for the laptop computer.

Resolving My Issue

I bought a Wi-Fi repeater a few years ago, and I figured I could use it to boost the signal. Unfortunately, I couldn’t find a place that circumvented the interference. Maybe I’m not doing something right, but I couldn’t create a hotspot with the Raspberry Pi 400. Well, I could, but only if I was using an Ethernet connection instead of a Wi-Fi connection.

I discovered that I could connect to the 5 GHz frequency with my phone and create a mobile hotspot with the 2.4 GHz frequency. I now use that signal with my laptop computer and Pi uses the 5 GHz frequency. My issue is resolved.

I can’t say when, but I plan to upgrade my fiber internet connection from 50 Mbps to 300 Mbps. The 2.4 GHz frequency’s bandwidth is saturated by my nieces and nephews using both phones and laptop computers at all hours of the day. That upgrade may solve my signal issue, and it may not, but I noticed I get a stronger signal when I’m awake and they’re not.

Wi-Fi 6

I’ve been reading about the new IEEE 802.11ax standard, also called Wi-Fi 6. Because it incorporates cellular technology, it should help eliminate some issues. Your equipment isn’t going to take advantage of it unless you’ve acquired it recently. Both the sending device and receiving device has to have been made in the last year or so, since Wi-Fi 6 didn’t exist before 2019.

The solution for upgrading a computer is to use a USB wireless adapter compatible with Wi-Fi 6 and then disable the internal Wi-Fi receiver. That won’t make sense unless the router also supports Wi-Fi 6. I’m not going to worry about it until I have to replace my computers.
