I'm on a wireless network that is clearly accessing the internet yet I cannot find the IP of either of the Access points I am using. Both linksys. One I have hard reset and still nothing using Look @ Lan. Any help?

it's a linksys WAP11...the default IP is 192.168.1.245, but even after resetting it and connecting it directly to my laptop it still won't show an IP...even though I can go through it wirelessly.

This is happening on three identical APs in three different locations in the house.

It's a AP so how did you "Connect it directly" to your laptop? There should only be one RJ45 port on the back which is used for the internet.

Does the above mean that you can connect to it wirelessly?

Why do you need the IP of the access point?

How do you know its accessing the internet?

I don't understant the "the default IP is 192.168.1.245"
That is not the default IP address for a linksys router. They are set to 192.168.1.1..
you could be getting 192.168.1.245 if that is the address the AP is being assigned by a router, in which case that is the IP of the router. 192.168.1.245 is a private IP that is assigned to a asset by the DHCP in a router or AP it is not something that a hard reset linksys will take for itself.

"That is not the default IP address for a linksys router. They are set to 192.168.1.1.. "

It's not a router it's an AP. A WAP11 specifically. That would however be an odd default IP. I would expect .254 as a more likely "default" ip than .245.

OP, it would be a long way to go about it but you could ping all the available addresses on the LAN.

Just as an FYI, the linksys AP may in fact have a hard IP for configuration changes but no IP is needed for connectivity from the client. an IP is completely irrelevant other than making changes on the AP. It is a managed wireless hub. The IP is ONLY for mangement. Passes all the data sent to it unless you configure it otherwise.

by "connecting directly" I mean I plugged one end of the CAT5 cable into my laptop and the other end into the WAP. This is how Linksys has you do the inital setup.

I need the IP of the WAP to get into it and make changes to the SSID and security settings.

I have used multiple methods of attempting to find the IP, and even the router (Linksys) does not believe that it is assigning IPs to these WAPs, because they are not listed in it's DHCP client table. Look @ LAN essentially pings evey device on the network and returns it's IP and description, but it cannot find these WAPs (on two entirely different networks now).

I also used "arp -g" on the host to manually assign an IP based on the MAC address and had no success.

All of this while connected to the network and internet wirelessly through one of the APs.

As I mentioned, you don't need an IP on the AP for connectivity via the AP by the client. IP for the AP is irrelevant to the client machine.

Sounds like it doesn't have an IP at all. Which is fine as far as using it but you couldn't configure it obviously. Is there a way to default it, via the manual?

Default your WAP, the default IP for the WAP11 is 192.168.1.251. Change your laptop to a static IP of 192.168.1.1 . Connect your laptop to the WAP and you should now be able to access it.

I've defaulted two of the three with no result except changing the SSID back to the default 'linksys'

looks like it's time for some new equipment.

Are they all old, not been used in a while? All stored in an attic under extreme conditions? That seems a little too odd for all 3 APs to be bad doesn't it.

The WAP11 is probably the best 802.11b Access Point.

Unless you need to switch to 802.11g there is No point replacing them.

Plug each WAP directly to a computer (using a crossover cable) with the computer IP on auto and try to configure what ever you need to configure.

If you can not change the IP range of the WAPs change the IP range of your Router and Network to accommodate the WAPs.

The point is that I cannot FIND the IPs. If I can't get into the WAPs, then they're useless to me (in this case) because I cannot change the security settings.

the chances of you having 3 bad AP's is remote. Reset to defaults

set the IP on your PC to 192.168.1.10 with a mask of 255.255.255.0 and then run angry ip or another IP scanner to see if any IP's respond. If so, then you know what the IP is, try and get into the web interface. If not, then move to the next range.

Ranges I would try: 192.168.1.X/24
10.0.0.X/24
10.10.0.X/24
192.168.0.X/24
