Increased my JioFi M2 signal strength and coverage to a considerable level. about 70% better if not more. Tested with signal strength meter, it's woks great! The wired/wireleareass router can act as a router, repeater/extender/booster, creates strong wireless network with greater coverage area.
It is a very good router. The range is good for 2.4 GHz. The 5 GHz have a low range but it is normal with 5 GHz. The only problem I found out is that if we are using the 2.4 GHz and 5 GHz at same time on different devices, the one with 5 GHz isn't fast enough i.e. the bandwidth distribution between both the bands doesn't seem equal. Otherwise it is a great product for its price.
