'[EE]: Wireless ssid ?'

Hi all,

I have 3 different wireless ssid and I was wondering if I change them to same name is better?

main router (1) ------------------------to linksys e4200 as access point that gave me 2 more ssid  (5g) and (2g)

they are far from each other about 70 feet a way and connected thru wire.

my question is if I use same names is it going to create conflict? 

any idea or suggestion?

thanks

Andr

The "normal" way of doing things is to have each AP running with the same SSID. That way each device can choose the strongest signal. Theoretically it also allows devices to swap APs when you move around the house.

The only problem with this is sometimes devices get confused and hang on to a weak signal too long, but considering how you are doing things right now I don't think you'll see a difference.

They will not "conflict" by SSID alone. One thing you SHOULD be doing is ensuring they are on different channels. This will be site dependant, but generally, for 3 APs in the 2.4GHz band, you should set the channels of each AP to 1, 6 and 11 (note that these are the only non overlapping channels in the 2.4GHz band). This of course depends on your environment. For example, I've got some neighbours with very strong APs on channels 1 and 6, so I use other channels to reduce the interference.

I would say yes, if you can easily maintain passwords/keys across the APs.

There are a few different ways you can do it:

I think the main thing to deal with is how you assign IPs.

For my home network, I use the same SSID/WPA2-PSK pair on two different
APs on different channels.  One AP is in my house, the other is in my
garage/office, about 150 ft away, and the two wired networks are connected
by a 5GHz 802.11n bridge.  While it doesn't really allow movement between
APs like jumping from cell tower to cell tower, it does make it very easy
to move devices between the two networks (like my phone which will stream
data over Wifi).  I'm sure there are more secure ways to do it, but
wireless in general is a compromise between convenience and security.

What are you using for the bridge between the buildings?

I'm using a Mikrotik RBSXT <http://routerboard.com/RBSXT>. Quite
reasonably priced at $89 US each. Setup was not trivial as these are real
enterprise class type devices, so there are a plethora of options.

I got really frustrated for a long time while setting these things up, but
once I did get everything right, the operation has been seamless.  These
offer some features that at first appear trivial, but are vital if you're
trying to make a "wire-replacement," such as DHCP forwarding.  They are
"power over ethernet" but not according to the IEEE standard, so you do
need to use their specific power injectors.
