Any ideas why my wireless connection keeps cutting out at home. It worked fine for a couple of years but has become increasingly less reliable. It will be connected for about 5 minutes then I lose it. It is not a problem when I use other wireless connections outside of the home.
Can you check the "signal strength", either at the router, or at your computer? (Different OSs perform this in different ways.) Are you using 802.11b, g, or n? How many other networks are visible to your computer? (It shouldn't make a difference, at least not directly, but if another network is showing a very strong signal it could interfere with your own network.)
Wireless connections use multiple "carriers", and if one of the carriers drops out then only the stronger remaining carriers can be used, reducing the connection bandwidth. Think of it this way: with only one carrier, you get one bit at a time. With two carriers, you get two bits simultaneously. With three carriers, you get three bits, and so on. Then, with the way they interact the don't add up to one, two, and three times the data rate (times n), but one, two, and four times the data rate (power of n). There's more to it, obviously, but that's the model to think about.
Carriers can drop out due to interference, or to weak signal strength. And if a carrier were to drop out after the connection has been established, the connection is likely to drop. Also, despite what some have suggested, growing steadily weaker over several years is not a common failure mode for wireless electronics.
And, as an aside, a wired Ethernet connection uses two pair of wires (four wires altogether), regardless of whether it's running at 10Mbps, 100, or 1000. A typical Ethernet cable carries four pair of wires, but two of those pair are not connected to the electronics.
