Access Point vs Repeater

ya all access points are connected with cables coming from all giga  Linksys switch . and all my access points are 802.11 b/g/n.
should I use same channels all ? as now I did ?

as long as they're Access Points - use different channels
channel 1, 6 and 11

how? i have around 10 access points so how should i choose to put channels ?
please advice

and which channel should i keep for main router as i have kept it on Auto now ?
please advice

is there any software which can autofix the wifi channels ?
please advice

Set one up as an access point and the others as a bridge.  You then need to associate the bridge to the access point in the setup of the devices

There are no software other than the builtin for enterprise APs that handels this.
Radioplanning is always a problem with 2,4 Ghz

But there is not the end of the world if you have some channel re-use or they're all on the same channel. The only thing is that APs that share channel, also share bandwidth.

if you have 2 APs, AP1 and AP2. They're both on channel 1

When a user on AP1 sends data, all others users on AP1 needs to stop sending data, and same goes for all users on AP2.
If a user on AP2 sends data, all other users on AP2 needs to stop sending data, and same goes for all users on AP1

If they would be on channel 1 for AP1 and channel 6 for AP2 then one (!) user on AP1 could send data while one user on AP2 can send at the same time --

As i have 10 access points ( mentioned above ) i have given different channels to themlike
channel 1 to access point 1 , 2 to access point 2 etc like wise given to all 10 access points .
is it right ?
please advice

Have a look at inSSIDer, it will give you all channels and they should be next to each other with as little overlap as possible.

Marcus

insider will show the channels required or it will show the existing channels ?

It will show all WiFis and their channel in real-time

With 10 APs you're bound to have some overlap. How many clients do you have?
if you have few clients online - then overlap is not a big problem, unless you have 10 other wireless networks from neighbors and such, which overlap with your network

As Marcus mentioned, inSSIDer is a great piece of software - it will pick up all wireless channels nearby, so you can see if your neighbors use channel 6 and put you off on that one.

Here's a picture of overlapping channels. As you see - channel 6 overlap from channel 4 to 8, channel 1 up to channel 3 and channel 11 from 9 to 13 ---
quite messy really -

and to make it even messier --- you have all kinds of other interference that aren't wireless access points - those you would not pick up in inSSIDer, then you need spectrum analyzers, around $600 - $1200

But if this is a home network, with few users --- i don't think I'd spend much time spectrum analyzing - just keep in mind that microwaves, baby monitors and AC might give you trouble

let me check
