Re: Neighbor uses 3 AP's and 1-7-11 channel range.

I might miss the reason for this, and maybe someone can shine a light on this for me:
Why would you set your wireless routers/AP to different channels vs keeping them on the same channel?
What's the advantage of choosing one over the other?

I assume your neighbor wanted to use several devices to cover the entire house with good wifi signal.

With some routers, you can go to 200mw-400mw.

Just for my own edification... which EXACT ASUS model do you know you can crank to that kind of power with DDWRT, sonarman See Profile ?

I do think that there is often confusion between software display and actual power measurement. As you probably know, measuring power radiation isn't that easy and it is unlikely that anybody here has such expensive equipment unless they're a transmitter tech. Also, even measuring the power dissipation of the output stage does not indicate radiation from the antenna. That's a perennial issue for radio transmitters.

My Shibby install indicates a range of 0 to 400mW, but Shibby says that those numbers don't indicate actual output and that after somewhere under 100 the transmitter will not put out more power. No doubt, like me, your were looking at that 400mW number with a gasp. They're just numbers on a screen and don't actually indicate power.

Think of it as trying to carry on a conversation with one individual while on a conference call with others, versus talking over a private line. Radio spectrum is a limited resource, and doesn't work as well with multiple transmitters on the same channel. Using different channels allows multiple connections to be active and not interfere with each other.

So, if I have 7 wireless switches/APs setup to cover a 3 story, 6 unit/section building, should I put it on channels 1, 6 and 11 with different SSID, or can I have them on the same SSID while having good performance and avoiding noisy "conversation"?

If you want seamless roaming, which most do when covering a facility with multiple AP's, you would use the same SSID and security method on all units. If you want to restrict access, or control the number of connections to each AP, then you could use a different SSID on each one. Either way, use only channels 1, 6, and 11 on the devices. Try and arrange them in a staggered layout, with the devices using the same channel as far apart from each other as possible.

I have a similar issue here my neighbors have a netgear 802.11n 300 and has it on ch 6 but some how using ch 1 - 11. causing issues with Wi-Fi, I did ask him about it and he did nothing about it. I did solve the problem by switching to 802.11A. I live in a 3 story rowe house i had to use 3 access points to cover the house. all are diffrent SSIDs and channels

802.11n can use 40mhz mode i.e. 2 channels max, a single AP cant use 1 through 11, multiple AP's can though.

If you use the same SSID on the access points, you can do seamless roaming across the house.
