We keep on getting emails and questions, like which routers we recommend for high speed fiber broadband. So, we recommend to go through this, this, this, and this. So, basically this AC router thing is not a cheap affair, as its all about proper hardware capable of transferring high speeds over the Wi-Fi which is expensive. Good is not cheap, cheap is not good :)
NOTE – Speeds over WiFi or range of WiFi doesnt come under ISP support. We can only suggest, recommend. We are not responsible whatsoever. You may have to contact the WiFi Router brands directly or hire IT system integrator firms, if you are really serious about your WiFi coverage and speeds.
