Hi I bought TPLink HB710 from StarHub for 10Gbps router, $192.No issues with that. SIMBA is using ONT so it is comaptible with all the consumer routers on the market. The only routers not compatible are those Singtel issued WiFi 5/ WIFi 6 routers with built-in Singtel VLAN profile.
But if you are looking at more cost effective model you may look at slightly lower end model -- TP-Link Archer BE805 (no 2.5G ports, no built-in OOkla SpeedTest utility). M1/MR users are dumping them in Carousell and the price is below S$360 and it will drop further to S$300 or even lower.
I bought one Archer BE805 at S$300 from M1 user recently.
What's the difference compare to BE805 $300?
