Current Events > i have a dumbass question about 2.4 ghz WiFi, so i don't get anywhere near my

(+) Yeah! (+)

advertised speeds on 2.4 ghz WiFi because they're like 20 different WiFi points around my area and some of these access points are invading my channel which makes my 2.4 wifi speeds lower?

And it doesn't affect my 5 ghz WiFi speeds because there's more channels on there and less 5 ghz access points floating around?

So if I want my 2.4 WiFi speeds to be close to my max speeds then I have to somehow remove all 2.4 signals around my area? (aka, almost impossible)

Well at least you admit it's a dumbass question.

Short answer: wireless is just slower than wire. Your advertised speeds are for the wire.

if you were to somehow eliminate all other signals, it would be a little faster but still nowhere near advertised.

addendum: 5GHz wireless is much faster than 2.4GHz but has shorter range. It's meant for things like streaming 1080p video over wireless.

Excessive amounts of signal can cause wave interference, it is the exact reason why 5.0ghz was standardized. You would need a way to strengthen or focus your own router's signal (Some routers allow directional antennae). You could also try putting your router closer to where you most use the WiFi, and putting the WiFi at a different height (Typically higher) to improve it's broadcast range and fidelity.

In the United States, there are only 3 clean channels on the 2.4 ghz band: 1, 6, and 11. The problem here is that the channels are 20 mhz wide, but spaced 5 mhz apart.

Channel 1 = 2.412 ghz or 2412 mhz
Channel 2 = 2.417 ghz
Channel 3 = 2.422 ghz
Channel 4 = 2.427 ghz
Channel 5 = 2.432 ghz
Channel 6 = 2.437 ghz
Channel 7 = 2.442 ghz
Channel 8 = 2.447 ghz
Channel 9 = 2.452 ghz
Channel 10 = 2.457 ghz
Channel 11 = 2.462 ghz

The channels being 20mhz wide but only 5mhz apart means each channel interferes with neighboring channels.

Most people have no idea what they're doing in regards to choosing a wifi channel, so they just let the router choose one on its own. Not to mention it'd be nigh impossible to arrange an entire neighborhood or apartment complex into the appropriate layout utilizing channels 1, 6, and 11 because people generally don't give a crap and nobody wants some random person messing with their router. All future internet problems would be blamed on said person, too.

5ghz channels are 20 mhz by default (can be bonded to be 40 or 80 mhz wide for increased throughput), but the channels are spaced 20 mhz apart so every channel in the 5ghz range is considered a clean channel.

The advertised speeds are theoretical maximums. Actual results will be less.
