Windows 10: What are WiFi "channels" and why should I care?

I keep seeing references to these channels but I thought that only the frequency ranges were important.

:)

 

about " memory full . close ... " problem ! n97 and equalizer !

i dont have any problems of those u listed i exit frrom all applications when i finish ! well this means there is no solution so thanks a lot nokia

and about the music i was talking about the phone loudspeaker .. !

 

about " memory full . close ... " problem ! n97 and equalizer !

1-hey ..! i did a format to my nokia n97 few days ago .. before i did the format i had the problem that sometimes when i go to photos its says " memory full close some applicartions ..." and now i have it again ! so i just wanna know how to
solve this problem its really annoying !



2- my best music kind is trance ,, but i dont enjoy listening trance on my n97 coz music does'nt sound good for this kind of music .. so i want to know if there is a way to make n97 music sounds like x6 or even 5800 ( i guess ) .. through some
application or through equalizer or whatever ! i dont wanna get another phone

hope u help me .. ! thanks

 

Within the same frequency band (2.4 GHz, 5 GHz, etc.), each band is segmented into a number of channels, dependent on the band standard (802.11n, .11ac, etc.). For example, the 2.4 GHz band in the US is segmented into 11 channels.

You, as the admin of your own router, can select to use the default channel set up by your manufacturer -- or you can change it, to prevent easier detection by "wargamers" or to reduce interference. (Consider: if you live in a large multi-family dwelling unit, you could have tens of routers set to the default channel, all colliding for the same channel.)

 

Wifi Channels are just like TV Channels appear on an Oscilloscope. They are a square waveform that the ends can overlap other bands. The problem that you run into is congestion, just like if you were in a huge market area, say NYC or Chicago and cannot tune in a low strength channel, because a higher strength channel is causing you to not be able to tune it in.

I use Channels 1 & 5 for my Wireless N Access Point that is 2.4 GHz. Cisco has a lot of good networking stuff, along with some of the other websites that get into the meat and potatoes about it.

 

So are you saying that I should change the default on my router to something else than the manufacturer's setting? That is, if my cable modem allows me to do that, and I'd have to check.

 

Yes always change the channel setting for "Out of the box", since it could be set to be on a congested channel. inSSIDer has always been a go to for everyone. It is no longer free, so you would have to pay for it, or try one of the other free choices out there. You can get around extra software, by opening up a Command Window and enter "netsh wlan show all" (do not use the quotes, they are just there to make the command stand out).

You will be able to see signal strength of A/P's around you and what channels that they are set to.

 

inssider is free here:

inSSIDe is a nice little program. It suggested for me to change from channel 3 to channel 11. My Link Score went from 35 to 100. *Smile

 

There are even some access points that can choose the best channel automatically. Here in France, where we can use two more channels than in the US, channel 13 is often a good choice since APs never default to this and it's generally underused. I guess channel 14 would be a good choice in Japan since they accept up to 14 channels.

However, choosing channels outside the US regulatory domain can pose problems sometimes since some bad setups can refuse to connect. I've seen such a problem with an Apple laptop once.

 

And you also have to watch for hidden devices that use the WiFi channels as well. I have a Sony home theater system with wireless rear speakers. The speakers have a switch to set channel A, B, C. I looked up the technical specifications and it said that channels A, B, C were something like WiFi channels 1, 5 and 11. So, I've got the wireless speakers set to channel 11 and my internet WiFi set to channel 1-3 (40 Mhz bandwidth).

 

I always try to stay at the low channels, because some devices have poorly designed chips for wifi in them. They tend to not like the higher channels. Plus where I live, Channels 1-5 have hardly anyone using them.
