Aironet 1242 AG as Repeater

Unanswered Question
Jun 2nd, 2008


I want to setup a bridge between two sites. The root bridge which is installed at the first site cannot cover the second site's area. For this reason I want to use a repeater between these sites to increase the signal's strength.

I have 3 aironet 1242 AG

1. root bridge

2. repeater

3. non root bridge

I can't make this scenario play. The Repeater cannot repeat the signal from the root and the non root bridge cannot associate with the root bridge.

Can you Help me?


I have this problem too.

Don't think this will work... You need to look into a higher gain antenna perhaps to get your signal across.

Why don't you try to have the following connectivity


Now depending upon the distance of root and non root bridges you need to decide whether you can go with an omnidirectional antenna at the root bridge.

Non-Root would have high gain directional antennas.

What you can do is to have a directional splitter at the root bridge and direct the signals in only two directions instead of 360degree horizontal coverage.

or else second option is -


Directional antennas on all bridges.

Repeater option is not going to work.

Let me know the distances between the two locations and the intemediate location where you were planing to have the repeater.

Hey John I realized that you have 1242AG series. I guess following should be ideal for you -


All directional antennas. Central Bridge would use both the radios while bridge on one end would use 802.11A while on the other end would use 802.11G.

Thank you for your answers, but can I make a repeater for a bridge between root and non root?

Get rid of the repeater and use a higher gain directional on both ends.
