Dear David, Thanks for your kind reply. I bought a Tp-Link Deco M5 Mesh System to broad my wifi range. However, I have an issue of setting Tp-Link Deco M5 Mesh System in my office. As you can see from the below picture, the Mesh System shows red light. (It means that the Mesh System is not working.) I think the reason is that I didn't choose correct internet connection type and IPTV/VLAN (On or off) when I try to set up Tp-Link Deco M5 Mesh System.  Since I don't have enough knowledge of internet, I don't know how to choose internet connection type and IPTV/VLAN (On or off). Do you know how to get the information of my internet connection type and IPTV/VLAN (On or off)? Thank you. Kind regards, Paul Lee ... View more

Dear David, We use 5 PCs over the only one band. Thanks for your information. As you said, I will keep the VR 1600. Also, I will buy wifi extender (or mesh unit or access point).   By the way, I am just wondering if only few sorts of wifi extender can be connected to my modem (VR 1600). I looked around Eshop for searching a good modem, but I can not find the one because I don't have enough knowledge of wifi devices. I don't want to spend money for the product which can not be used in my office.   How can I check if the wifi extender (or mesh unit or access point) can be connected to my modem? Can you recommend a good wifi extender which can be connected to my modem for me?   I always appreciate for your kind response.   Thank you.           ... View more

Dear David, When I typed my business address at  nbnco.com.au., nbn® Fibre to the Node (FTTN)* is the only option (Same as what I am using at the moment).    Belows are firmware version and hardware version from the Archer router. Firmware Version:1.1.0 0.9.1 v5006.0 Build 221128 Rel.12146n  Hardware Version:Archer VR1600v v2.0 00000000   I use the TPG VOIP phone function, so I think I have to use the TPG supplier router as you said.   After I turned off and on router, my internet is stable. Before I turned off and on router, there was slower response.  Our office uses wifi by 5 computers. Our office doesn't use ethernet computer.    Can you recommend a good router model and wifi extender? (Price doesn't matter.) ... View more

Dear David,   My internet is wifi (Not Ethernet). I think my plan speed is NBN 100. Here is the result of my speedtest (just now) on TPG support page.  Download: 109.8 Mbps Upload: 36.7 Mbps Ping: 13 ms   Yesterday, I turned off and turned on my modem. After that, my internet is stable now. However, I want to find the way to improve internet quality because my boss wants to use computer with better internet.   I'm sorry, but I don't know what Archer means.    I think there is no way to improve internet speed with TPG internet. Will it be helpful to improve wifi range and stability if I buy a new modem? If it will be helpful, could you recommend a good modem?    ... View more
