I used JIO sim in Archer MR 600 router and it was working fine. I event set the band manually and then also it worked fine. Yesterday I rebooted the router after experimenting with band and from then it is not connecting to internet. I did hard reset and everything is in Auto mode but then also it is not identifying JIO and Airtel network. It identified Vodafone but that also working in WCDMA mode. No 4G.

Same Sim is working absolutely fine in iPhone 12 mini. JIO sim when working in router gave me max speed of 40 Mbps in my area and same in iphone 12 mini gave me around 100 Mbps. So perfomance wise also this router is not very satisfactory. Company like TP Link is just selling it for more money with mentioning 4G+ Cat6 router but performance is mediocore as compared to mobile phones.
