Upgrading modem/router need advice

[thesmallaussie17]

I live in Australia and my area is finally getting a fibre connection and our modem/router is only ADSL compatible and not VDSL/VDSL2 compatible so we need to upgrade. I'll try and provide as much info/details as possible as context is key. We currently have a Netgear D3600. 

 

We have a two-story house and we keep the modem/router downstairs as that's where the majority of devices are. We have 4 laptops, 5 phones, one pc (wireless connection), one xbox (wireless) and 3 set-top (cable box) boxes (wireless) that are connected to wifi. At minimum we would have 5 devices all using wifi at the same time however I would generally say that we would be have 6 - 8 devices going at once. At the most extreme use we would have 5 people streaming video, one xbox/pc on online multiplayer games as well. So, in general we would need a modem router that would be able to handle that kind traffic. We haven't looked into cabling for the PC, xbox or set-top boxes however that's in the works so don't feel like you to address the cabling issue, unless you want to. 

 

We are going to be going for the a 100Mbps connection at first, there is also a 250Mpbs option that looks tempting as well so I'm bearing that in mind as well. I was thinking of going with a separate modem and router combination instead of a modem/router combo. At the moment my PC is the only device with the 802.11ax standard the other devices would be a combination of the N and AC standards. So, in that regard I was thinking of getting an AX router however I'm also wanting to get my PC on a wired connection so I'm not sure if going an AX router is the best option right now or to get it for devices that get replaced in future and may have the AX standard.

 

I'm still in the researching stage however if you guys have any thoughts on whether to get the modem and router separately or just go for modem/router combo? I thinking of a budget between $300 - $350AUD ($205 - $240 USD). I would need I router that has pretty strong range as well.

 

If I do go buy the modem separately the modem I was looking at is the NETGEAR DM200 (VDSL/VDLS2 compatible) (https://www.scorptec.com.au/product/Networking/Modems-&-Routers/64538-DM200-100AUS). 

Let me know if you need any further info. Cheers.
