Use GL-X3000 as the main router, tried to setup satellite AP with other GL routers in WDS mode, and none worked. Have tried GL-X750 GL-SFT1200 GL-B3000. For all of them, I could complete the WDS mode setup wizard, and satellite AP could find and make connection to main router and turned on WDS mode. But afterwards, the satellite AP does not show up in main router's client list, and computer that connects to satellite AP could not obtain IP address.
This makes me thinking whether GL-X3000 supports WDS mode at all.
Before moving to OP24 firmware, X3000 as AP, MT6000 as client, it did not work.
With OP24 firmware, X3000 / MT6000 work regardless which is AP / Client.
