Hello. First time in . . . testing the water . . . Ah, looks good. Lots of smart folks hanging out here.

I am building a wireless system from scratch. I won't get into the range I need to cover, or the number of people it needs to serve, because it's basically irrelevent to the question I have spent a few days trying to get answered - to no avail!

Is it possible to set up a completely redundant wireless network? Meaning, you have two wireless networks up and running at the same time, covering the same area, and if one goes down it is mostly unoticed by the users.

I am familiar with the general concepts of roaming, WDS, spanning tree, et al. But can you pull off a dual system without the two systems stepping on each other? If so, do you set the channels the same or different? Do you set the SSIDs the same or different?

Has anyone been down this road?

THANX!

The trick is to have a router that support roll over. The Netgear FVS538 is one that supports rollover.

You set the wireless (AP's) up like you would a single WAN. With a roll over router when one goes down it auto swithes to the second source. So no service is dropped.Some even supply load ballancing.

Thanx for that reply. Seems worth looking into. I am investing in the Linksys WRTGS because of the firmware hack to boost the power. It would be swell if those support rollover (she said with her fingers crossed big time).

Cheers

If you are looking at AP's Take a look at USR 5453 AP, it's got some nice options... It to is linux based.

Thanx for the tip on this. The access point actuallyhas just what I am looking for. They are calling it "clustering". The only downside is that it is new. Have you used this unit?

I am going to make a new post to see if anyone has put this unit into production.

I have the 5450 model. It has been a great unit, more power than I need. Covers my whole house on LOW Power. It has only locked up once in the 20 months that I have owned. An I think it was related to a strange power cycle. Rock solid. I have never know USR to release a product that did not do what was advertised. The have a good ruptation when it comes to hardware.
