TP Link CPE210 is AP for 3 more APs in range

You mean you have 3 others repeating to this 1? Or its routing and then you have 3 others as wireless clients to it in a wireless client bridge setup?

If your in a setup where you have to use wireless uplink to have these AP get connected... Then do that - setup a fullmesh network or get AP that actually support wireless uplink and not some client/bridge/repeater nonsense..

Best option is run a wire to where you have need of AP for coverage.

@JKnott
Second AP is currently configured as Repeater. I tried both AP and Repeater modes and faced same problem in both.

I chose pfSense to use my current hardware. Since for Mesh I need to upgrade firmware which is not possible with available hardware.
Can't run wire for almost 2 km to cross the motorway unless digged deep with right of way to cross that.
But your answer is logical that repeating and APs in client/bridge/repeater nonsense are nonsense - lol.
Anyway - Thanks for suggestion

So your "repeating/client/bridge" for 2 KM?

Get the correct hardware for what your doing - if you can not run a wire.. You could use something like

As the link to your remote location, then connect your AP to that..

i have a dlink access point that do the same (dap1620 rewrite the mac of connected devices) and there is no way to remove that behavior. i have to live with that until i change it for something better. total BS

That doesn't sound right. If the d-link MAC address is used instead of the device MAC, then it becomes impossible to have more than one device connected. DHCP relies on the MAC address to assign an IP address. Does a device connected to it get an address from the LAN? Or a separate network?

I have just browsed through the manual for that device and didn't see anything to indicate it operates in anything but bridge mode. I have a couple of devices, one Asus and one D-Link that can be configured in a variety of modes and they both work properly.

Consumer grade WiFi gear isn't the best way to do that. There's a variety of short haul microwave gear that's designed for that sort of situation. I have worked with equipment from DragonWave and Ceregon.

Looking into these - they do support a ptp mode, as just a wireless bridge.. That is how you should set it up, and then connect a different AP to that.. So now you just use that link as backhaul..

You would then see the mac of the end point devices.. Your ptp devices become a wire so to speak..

@JKnott this is the mac of one of my AP repeater 10:62:eb:f2:1f:44
every device connected to it become 10:62:eb:* or 10:62:* i don't remember exactly now as i'm not at home right now

Well, better check when you get home. The situation you describe doesn't make sense.

Yup, wifi repeaters re-write the MAC address. First time I saw that it freaked me out too.

So, how many devices can you connect via the repeater? If only one MAC is sent to the DHCP server, it will provide only 1 IP address.

stephenw10 · Oct 30, 2019, 5:08 PM

I've never dug into it because it seems like black magic and best avoided but....

I assume it re-writes the first 3 bytes of the MAC with it's own OUI as shown by @kiokoman above.

Ugh...

Then you'd still have different MACs and IPs. However, according to the OP, several IPs have been assigned to the same MAC, which might not be true. However, he's only had 1 post since then and he doesn't clarify anything.

naeemirza · Oct 30, 2019, 7:01 PM

@JKnott Actually I removed the simple wifi repeater and using AP now. It solved the problem. I have been experimenting with Repeater to record multiple IPs against same MAC. I will post some screenshots here later.

Yeah my mistake. In fact that is what I've seen before, the same MAC used for all IPs coming via the repeater.
Which is what the wikipedia page shows as expected: https://en.wikipedia.org/wiki/Wireless_repeater

As I said it's all voodoo! Avoid if possible.
