Yesterday I was looking at replacing some access points for a client and couldn't tell who the manufacturer was, they had a squiggly Z type logo on them, any ideas?
Use a wireless network scanner. My preference is inSSIder by Metageek. They still have inSSIDer for Home for free. You can get the MAC address and then plug that in on any number of websites that parse the MAC address to the OEM manufacturer. As always a picture would have helped a lot.
