I've exceeded the maximum number of MAC addresses in my router?

[gerrym]

I have a Linksys E3000 router which has been pretty good for me overall for the last few years. My problem now is that by locking down WiFi access to my network by MAC addresses, I've run out of slots so I now have to disable that feature or reduce the number of devices.

This router is about 3 years old so I figured it may be time for an upgrade anyways but I don't see this specification advertised anywhere. Do you guys know what router has the ability to filter more than 32 MAC addresses? It would also be great if they could have a name associated with the MAC address, like my old Netgear router did. For example, "Mom's Laptop" xx:xx:xx:xx..., in the E3000 I can only enter the MAC address in the filter table, so when I'm looking to remove any I have to go to my excel spreadsheet where I keep a table with the devices associated with the MAC address.

Thanks,
Gerry

MAC address filtering is of questionable value in securing your WIFI network. Use WPA2, AES with a suitably long and arbitrary password and don't worry about MAC filter white-listing. Anyone that REALLY wants onto your network would have the capability to sniff out white-listed MAC addresses and spoof their MAC address to a white-listed one.

It seems like a limitation by the current bios. Try flashing DDWRT on it or update the firmware. They only allotted memory for 32 MAC addresses, but a bios update may have allotted more.

I know this is not an answer but limiting access by MAC address is completely worthless from a security perspective. You should just disable the feature and use a strong WPA passphrase instead. Use Radius authentication if you really need to limit access.
It is trivial to change the MAC a computer advertises and since computers broadcast their MAC anytime wifi is enabled it takes little effort to steal a non-blocked MAC.

Netgear ProSafe devices allow 128 MAC addresses. But as Calculagator said, MAC-ACL is inferior to a good WPA2 passphrase.
