How do I find the wireless access points?

Recenty on the job, the wireless that used to work does not work anymore. The SSID does not show and it work with no password open for everyone to use.Since recently the consulant who used to configure and initially install the wireless has left. Since then everyone has be complaining that they can log on is there a way to check for tcpv iew. I noticed belkin access point but I am not sure if it was covering so a far distance it was doing before when everything was woirking. I am not quick to reset wireless router because building has two networks 192.168.1.1 and 192.168.2.1. 192.168.2.1 goes to another router and 192.168.1.1 goes to a unmanaged switch.

I am afraid if I reset the router I would be unable to configure the lan setting. Therefore before I go ahead with the least choice I would like to know if there is a way to detect access points on a network.

use a WiFi "sniffer" -- easy and legal.
The best one is inSSIDer from www.metageek.com and you can also use net stumbler at http://www.netstumbler.com/downloads/

If you perform a hard reset you must (but can) configure networks againg. But if you connect to AP with cable, can you log on to the AP?

The reason don't reset the router because of the down time it that may occur. For now I am just trying figure out their network setup and also where their access point/wires routers may be located because they once got internet in certain areas but now they do not.

is this a complex network with several APs? or just a simple with one?
If you have several they should show in inSSIDer on different channels

you don't know the APs exact location?

no I don't know there exact location. I would like to know their exact location or if they exist because there were wirekess in areas now there aren't there. This much i know is that if their were ap then they were connected to the network so I wondering if there was a way to scan and find access points.

You could try some kind of network monitoring software, like Solarwinds or something - but they all cost money.
You could try to sort out the IPs that are in exclusion range on DHCP (hopefully any APs are set up with staitc IPs) and try to connect via web-browser and see what the title line or login web says ...

maybe this :http://www.spiceworks.com/
or this: http://www.solarwinds.com/ or this: http://www.10-strike.com/lanstate/
