Dual WAN worth it?

[Bobbish]

Hello!

My flat is two flats joined together, and so I have dual fiber lines (100/100) coming in to different parts of the flat.

It’s the same ISP but two separate customer profiles. Currently there are two modem/router combos from the isp, one for each line.

I want to use my own router and put the ISP gear in bridge mode.

Any sage advice on how I best can use the two lines? I could just put each on a different WiFi, creating two networks for different parts of the flat. I could also just leave one line unused and set up a mesh network from one of the lines (to get a single network covering the flat).

Is there any real benefit for normal ”household needs” of trying to put both lines into one router with dual wan and from there set up mesh APs?

Is it at all possible to have a dual wan mesh where the WAN connections are to different units? (Would save me having to drill/reroute the cabling).

I don’t really have any advanced needs, just want a snappy connection and would prefer a single network.

Not with ASUS gear. Seriously, residential use would easily fit in 100 Mbit/s ISP service. ii used to have 38 Mbit/s ADSL service for 5 people - 2 corporate work at home, 3 kids including 1 gamer. Occasionally noticed slowdown if downloading large files. Since it is same ISP, same fiber branches from their network, and same power sources, lots of common mode failure points. So keeping one as backup to the other is not likely to work except for a local fiber cut or ONT/modem failure not caused by power. Save your money and just keep the one service.

And joining the two services together are not likely to improve "snappiness". You still have 2 individual 100 Mbit/s links running with light bandwidth loads. BTW, many internet facing servers limit individual session bandwidth to around 100 Mbit/s or so, anyway. All you would be doing is making the ISP happy. Invest in your local LAN infrastructure so you have good wifi coverage, hardwired LAN devices, and locally "snappy" link rates.

Cancel one of the ISP lines and save money. Use the saved money towards single ISP line with higher bandwidth, if needed. In your current situation when the ISP is down both accounts will be out. Main purpose of multiple WAN connections is redundancy.
