Some customers tried to set up Mac Filtering on the main router to control the clients connected to the Range Extender, but they eventually found that their settings didn’t work normally. Here we will introduce the detailed steps to make it work.

Before we start, Please make sure your Range Extender has connected to the router successfully. Here we take RE305 and Archer C3150 for demonstration.

NOTE:

This article only applies to range extender that works on proxy mode. For some old-version range extender there are different modes and proxy mode can be manually selected.

Find virtual MAC address of RE and of the client connected to RE

Method 1

1. Check your client device’ real MAC address (94:DE:80:57:AD:E1), and write it down. You will need it to find the client device's virtual MAC address. Find the MAC address printed on the back of your range extender (50:C7:BF:1B:ED:C6). The latter 24 bits of each client’s virtual MAC address are exactly the same as the latter 24bits of client’s real MAC address.

2. Log into the Web GUI of your router and select Advanced->Wireless ->Statistics, you can see the MAC addresses of the devices associated to your router. By comparing these MAC addresses with the MAC address (50:C7:BF:1B:ED:C6) printed on the back of your Range Extender, you can easily find that“52:C7:BE:1B:ED:C6” and “52:C7:BE:1B:ED:C7” are the MAC addresses of your range extender associated to your router.

You can easily find the client’s virtual MAC address (52:C7:BE:57:AD:E1) by comparing to its real MAC address (94:DE:80:57:AD:E1)

NOTE:

1. For dual-band range extender, even though it’s linked to router on single band 2.4GHz or 5GHz (only 2.4G or 5G LED is lit), it may still negotiate with the router on other band as well, so it’s suggested to put those two MAC addresses of the range extender in MAC filtering list. If you have no idea how to check the Wireless Statistics of your router, please contact the vendor of your router for help.

2. You can also find the client’s virtual MAC address on wireless statistics list since the client is connected to RE which linked to the router wirelessly, so it will also show on wireless statistics.
