Upgrading Wi-Fi — What, When, and Why
lessthan0 writes "Wi-Fi (802.11x) networks have been around long enough that many businesses and home users run their own. The first widely deployed standard was 802.11b, while most new hardware uses 802.11g. The latest 802.11n hardware is just around the corner. If you run an existing wireless network, is it time to upgrade?"
for me anyway.
I have 3 problems with WiFi.
1) Too many people near by with WiFi makes the connectivity suck within my apartment(have tried many channels). How about a new system where base units can figure out the best configuration when there are others nearby and even change them when the radio pattern(/coverage) changes.
2) My existing devices are not compatible with "New" security standards, fx. Ipaq and wpa2. For every WiFi enabled unit you buy, you have the problem of not being able to upgrade your security unless all devices support it.
3) My HP notebook drops connection when a cellphone is used in my apartment.
There are so many things that can break my WiFi net that I still prefer to use cables. Thought about getting a Squeezebox with WiFi, but I think I might as well save the money and just use cable.
My understanding is that "n" provides longer range and better link stability. I think that might be a reason to upgrade. If you move files a lot between local computers, the speed might help too.
That said, given that there isn't a finalized standard, I think it may generally be best to hold off on upgrades. If you need speed for your local network and can't wait, then buy matched sets of network devices, then for elsewhere, you can fall back to b/g which should be a lot more than enough for Internet stuff.
