In today’s world you cannot turn around without finding some kind of wireless network. Be it at home, at the library, or even you local coffee shop. So chances are most people reading this blog have wireless at home, or if not have thought about getting it. One thing to keep in mind if wireless frequencies. Your standard home wireless router broadcasts at 2.4ghz. All of them do, with a few exceptions. But one thing you want to keep in mind are other devices that also broadcast at 2.4ghz, such as cordless phones.
This very thing happened to me a few years ago. We got new neighbors that moved in next door, and we became friends with them pretty quickly. Not long after that I kept noticing that our wireless network signal in our house would drop drastically, from like 54mbps to 18mbps. I spent months trying to figure this out, and had no clue. I tried every channel on my router, with no luck at all. Then one summer day we had our windows open as did our neighbors. I was monitoring my wireless connection and it was holding at 54mbps. Then I heard my neighbor’s phone ring, and as soon as they hit the button to answer it my signal dropped to 18mbps. Sure enough, they had a 2.4ghz cordless phone that did channel scanning. So whenever they were on the phone it would kill our wireless signal. So as an early Christmas present, I got them a nice 5.8ghz cordless phone.
So if you are planning a wireless network, or just trying to trouble shoot a problem like the one above. Maybe take the time to see what frequency your cordless phone and other devices use. If they are 2.4ghz maybe get a different device that operates in a different range, such as 5.8ghz or 6.0ghz. Even older phones that are 900mhz or 1.9ghz will work fine in a wireless network environment.
