WiFi network is that thing in our lives that makes its presence felt when it goes wrong, otherwise, if netul goes well, no no stuffing into account.
A WLAN that works.
Because WiFi network to function properly, we must meet some rules. The wireless router must be good, as this Asus AC56U or this AC87U; Positioning can increase our router coverage; the use of repeater It can greatly help defray some ample, but the most important is to Well configure router from the outset.

spectrum unlicensed that we can use all without license is restricted, should therefore be used carefully if we want performance and pleasant browsing experience.
From the almost complete Michael Gauthier, Wireless Networking in the Developing World - I created this work based on Image: 2.4_GHz_Wi-Fi_channels_ (802.11b, g_WLAN) .png, CC BY-SA 3.0, Link

WiFi available channels
In 11 channels are USA, and in Europe we 13 available channels. Now do not think that we can use 11 or 13 devices connected simultaneously. Each device uses multiple channels simultaneously and therefore have to arrange everything ordered to fit us all without stepping on each foot.
In the USA you can put on the 11 3 channel devices, and they will have every piece of tape and we will have no interference. In Europe 4 device can cram many sites in the broader spectrum of 13 channels.
In the picture below clearly see how the devices should be arranged on spectrum.

What we choose to channel WiFi?
You have to do a little detective work, using some apps for viewing area networks; This will determine which channels you have available or if some channels are free.
We can walk and channel width. Although a 40 mhz channel gives us better speedIt occupies more space in that spectrum, and therefore it is better to reduce the 20 mhz channel to avoid overlaps with other channels.
Wireless spectrum congestion
Many are asking: What happens if agglomerate radio channels?
You alone can answer this question if you imagine that spectrum is a highway and packet data are cars that go through the air; What else can you catch when the speed is super busy highway. In an area saturated with radio spectrum we have the slowing of traffic (low speed) and interference (nerves). If we go all motorcycle (ie 20Mhz) instead of drive (40Mhz) I fit more. as if I find some free bands as well as (channels 13 and 14).

it's normal to have conficts to many routers

What are you talking about ? .
conflicts
Cristi you can help me I installed to clean windows 10 pro, and I opservat that the system tray icon appears in safely remove hardware, and I'd like if possible to disable the tray icon safely remove hardware, but not all aces wants to be with 7 is to defend the system tray only when you insert a uSB stick into the computer, otherwise disappear!
I love you post Cristi Cizmaru because in momoentele where you panic and do not know what to do Cristi set ups can help with Windows and etc.
I have an upc router and I left it on the car. and at the frequency I also left the 2.5 and 5.5 and I never had a conflict. although they are within range of over 10 wfi routers. it depends a lot on how it interprets the channels and my router automatically detects when I connect a phone or laptop to it. and choose the most ok channel. much depends on the way of interpretation.
"the same if we found some free tapes that would be nice." You wrote be with two "i"
Thanks for the guy.
Cristi auzui incredibly slowly. Try with a microphone most advanced camera not built-in microphone
I hear better. And other visitors can tell us how to hear.
I hear you perfectly clear. If you have some hearing problems, not our problem. Ask your doctor!
Maybe you should tell the person who's complaining, what microphones you have. Not to dream of webcam microphones. I remember that one of the microphones you presented here also costs somewhere around 300-400 lei. Listen, webcam microphone. Yes .... what can I say, we have been doing tutorials since yesterday, not since 2008 :-))
I mean volume should give a lot. And when I listen to something on youtube is very much along as you hear yourself CRISTI
cristi I hear you perfectly. he didn't give a damn about either headphones or speakers. or pate has headphones / speakers made on the ship to go slowly (I recommend buying some headphones ok or speakers) or from the pc the volume is given slowly. or player yt. or if this is not an ENT check despite the fact that some of you have cristi, I say that you go to the microphone in the room :)). so what to say
I did not say that sounds stupid. Indeed hear clearly but slowly compared to other records that are found on youtube at the same level of volume compared to the records of Christ and those on YouTube, he hears slowly. And I do not know and do not know you believe me sit well with hearing. And I'm benchmark assembling PC Market Service. Calin sit in your bank
hello it sounds to me and I don't have special headphones
I can hear you well
Off-topic: you make a documentary about the Raspberry Pi using a RADIUS server. Thank you in advance.
