I took the 200 Mbps connection around 10 days ago in Nagpur. They provided a DragonPath Technologies router to me. It is probably being white labeled by Airtel, as the packaging has "imported by Bharti Airtel Ltd." written on it. They said Nokia routers are out of stock and now only these will be provided, at least in my region.
+1 Huawei is better, I have a Nokia g2425 and most of the settings are locked, can't enable bridge mode without backend request.
