Device connected to tplink repeater not getting ip's from Mikrotik DHCP

  • 1

I followed the tp-link(https://www.tp-link.com/us/support/faq/227/) guide these are the logs generated by MT. I set 192.168.88.2 as the fixed ip for tplink. Here EA:xx:xx:xx:xx:xx is the tp-link router that needs to work as a wireless repeater and 88:xx:xx:xx:xx:xx is some device that trying to connect with it. The only thing that I changed is that I fixed the wireless channel. The MT log is:
EA:xx:xx:xx:xx:xx@wlan1: connected, signal strength -71
defconf offering lease 192.168.88.48 for 88:xx:xx:xx:xx:xx to eth EA:xx:xx:xx:xx:xx without success

After modifying as per Mikrotik(https://wiki.mikrotik.com/wiki/WDS_repeater_example) here is the configuration export. Wireless part:

 0  R name="wlan1" mtu=1500 l2mtu=1600 mac-address=6C:xx:xx:xx:xx:xx arp=enabled interface-type=Atheros AR9300 mode=ap-bridge ssid="bad" frequency=2412 band=2ghz-b/g/n channel-width=20/40mhz-XX secondary-frequency="" 
      scan-list=default wireless-protocol=802.11 vlan-mode=no-tag vlan-id=1 wds-mode=static wds-default-bridge=none wds-ignore-ssid=no bridge-mode=enabled default-authentication=yes default-forwarding=yes 
      default-ap-tx-limit=0 default-client-tx-limit=0 hide-ssid=no security-profile=default compression=no



/interface wireless wds
add disabled=no master-interface=wlan1 name=wds1 wds-address=\
    EA:xx:xx:xx:xx:xx



/interface bridge port
add bridge=bridge comment=defconf ingress-filtering=no interface=ether2
add bridge=bridge comment=defconf ingress-filtering=no interface=ether3
add bridge=bridge comment=defconf ingress-filtering=no interface=ether4
add bridge=bridge comment=defconf ingress-filtering=no interface=sfp1
add bridge=bridge comment=defconf ingress-filtering=no interface=wlan1
add bridge=bridge comment=defconf ingress-filtering=no interface=wlan2
add bridge=bridge interface=wds1

But, still log error: defconf offering lease 192.168.88.47 for 12:xx:xx:xx:xx:xx to eth EA:xx:xx:xx:xx:xx without success.

All the modifications done to MT were in safe mode. But, after reverting I can still ping the tplink from MT(Step 1). But, other devices not getting IP’s from it.

This is normal. In the WiFi world (this is NOT a MikroTik-specific problem) you cannot combine access points and repeaters from different manufacturers.

Thank you for replying. Yes. It is not a MT specific issue. But, it would’ve been great if worked. Then again it is what is it :smiley:

It is worth checking that you have rstp turned off on the mikrotik’s bridge.
It often seems to be a bit of a showstopper in this situation.
(Apart from any other incompatibility issues.)
