Clients behind TP-LINK connected using WiFi to RB2011 can't get their IP from its DHCP

lotnybartek · September 25, 2017, 11:14am

Here is the deal:

I have TP-LINK 941 v5 (kind of repeater with AP) (stock firmware) connected to RB2011 using Wifi. Clients connected to TP-LINK 941 v5 get their IP from DHCP on RB2011.

This setup worked almost 18 months. Now, my RB2011 is flooded with this message:

… offering lease [IP] for [MAC1] to [MAC2] without success

where:

IP - is an IP of a device that DHCP wants to assign
MAC1 - MAC address of above device
MAC2 - MAC address of a TP-LINK 941 v5 WiFi AP

Any tips what could be wrong?

Bump.

I tried the same configuration with TP-Link 1043ND with LEDE/LUCI firmware but problem persist. I’m flooded (in RB2011) with:

… offering lease [IP] for [MAC1] to [MAC2] without success …
biuro (name of DHCP server) offering lease 192.168.10.11 for AC:22:0B:95:84:01 (my PC connected using wireless to TP-LINK) to 10:FE:ED:7F:40:48 (TP-LINK 1043ND) without success.

And yes, I bought hAP AC Lite and solved it using “station bridge” and “ap”, but still I’m pissed I needed to buy additional product.

I did not alter any settings in TP-LINKS for months - it just stopped working after “some” Mikrotik update.

Below it’s a log from RB2011 with DHCP details, still this problem is unresolved.
