Most advanced users will not use JIO router with limited options they will want to use their own gigabit router so JIO provides a cheaper option so you can cater to budget customer who don't want router for 4500rs and also you make those guys happy who want to use it just as a modem and use their own router many from this forum fall in thethe latter category ...
We are now taking about 1gbps speed but Jio stop providing Rs4500 Dual band WiFi router and they are only providing Rs2500 single band WiFi router (black colour) which have speed upto 50 Mbps on WiFi.
So Why they stop providing Rs4500 dual band WiFi router?
