How to find WAP which has DHCP disabled behind switch?

Gimpymoo · 11 May 2019 at 22:45

I have a router configured as a WAP which is behind a switch.

I have forgotten the IP address of the router and need to change the wifi key but owing to the config and to save faff, wish to avoid factory resetting it.

Any ideas as to how to find it as even though it has an IP, it if course is not broadcasting it.

I hope that makes sense.

Many thanks.

Use a subnet scanner.

If you can connect via wifi you should be able to see AP details from a device.

It just gives the details of the router/firewall, as though the WAP is not actually there

That is how I set it up though many moons ago so it is working.. I just forgot the IP AND the Wifi password so stumped myself.

Many thanks.

Giving it a go now.

Thanks, I will try that later.

If I connect directly via ethernet and run a subnet scan, is it likely to find anything?

Right now, it is acting as a pass through and is "invisible" to the network seeing as the router handles the IP assignment for the devices connected to the WAP if that makes sense?

Checked ARP cache on the router, and not there either

Determined not to reset out of principle now

To update and summarise.

Firstly, thanks to all who responded.

I tried EVERYTHING advised and more and for some reason, I could get get a whiff from the thing on the network, even when connected directly to a PC, wirehsark or the scanners would not pick it up.

I even connected a device to the router via wifi but when sniffing, the router acting as a WAP was completely transparent (Which is to be fair, what is should be doing).

In the end, the router was old and the wifi protocols were outdated and as luck would have it, I found an old Virgin Superhub 2 lying around so re-purposed that as a WAP and all good.

Just seems like it was the "perfect storm" of disabling DHCP and custom gateway address and your screwed on this specific router which by the way was a Netgear WNR2000.
