Hi Will, I ended up with Access Point solution with a cable connected to TP-LINK.   ... View more

Hi Will, I can't get internet when I connected to Asus (as second router in the home network).  I have internet access when I connected to TP-LINK. Thanks. ... View more

Thanks BasilDV, I probably messed up the concepts bridge and WDS.  I read the article about how to bridge TP-link 1600 and did so (https://community.tpg.com.au/t5/Modems-and-Devices/How-to-turn-on-bridge-mode-on-the-TP-Link-1600v/m-p/5718#M398).  I thought if I config WDS in DSL-N55U C1 then the two devices would work via the wifi bridge like this: TP-link 1600 (bridged) -> wireless bridging -> DSL-N55U C1 (in WDS mode). I configured WDS in Asus and could see TP-link as an access point.  But I can't get internet.  Probably because I thought bridging a device means put it in WDS mode. As the example you gave it seems they are different things.  Now with the two devices if I don't consider AP solution then I will have to give up. Thanks a lot. ... View more

Thanks BasilDV,   It seems access point mode will need cable conection between the TP-link and DSL-N55U.  So this maybe the last option I will go.   For bridge mode I looked at an artice from Asus support which points out that WDS needs to be configured in both routers.  See the link below.  I suppose this should apply to routers with different brands as well?   https://www.asus.com/support/FAQ/114612/   Would you shed some light on how to do with the two devices in bridge mode please.   Thanks. ...

Thanks Will, You are right.  DSL-N55U C1 does not support VLAN where I can't see 802.1q settings in the UI. For access point solution it seems I will have to connect a cable between this modem and TP-link V1600 which I don't prefer. What I am after is to utilize WDS (bridge mode).  I did see an article about how to set bridge mode for TP-link v1600 as below.  I am not sure if those steps in this article only apply to DSL connection or it works for the WAN port as well (the cable is connected into tp-link v1600's WAN port from the NBN modem), please confirm.  I knew I can set up bridge mode in the DSL-N55U C1.  I suppose if both deives in hands can be bridged then this will be a good solution for me. https://community.tpg.com.au/t5/Modems-and-Devices/How-to-turn-on-bridge-mode-on-the-TP-Link-1600v/m-p/5718#M398 Thanks. ...

Thanks for the quick response.  I went to Asus website and found below for this device (my one is actually DSL-N55U C1): The DSL-N55U has two WAN (Wide Area Network) ports, allowing it to be used as a standalone router when not operating as a ADSL modem router. You can choose which mode suits your needs at any time, reducing cost and clutter by not having to buy separate power-consuming devices. Whether for a basic home setup or a full wireless network, this dual-WAN design gives you total flexibility. Correct me if I am wrong, if I config this device as Ethernet WAN, it should work? https://www.asus.com/au/Networking/DSLN55U_C1/?SearchKey=n55u/ Thanks. ... View more
