HELLO, I just want to say that I am using Rail wire in Howrah station since June 2014 to till now July 2017, I have not found any problem in Howrah Railway Station.
I never raised any complain till now since there is no disconnections( 5 to 10 minutes outage happened 3 to 4 times in last one and half years).
Also I am getting full speed at any time. I subscribed for 10 MBPS and I am getting full 10 MBPS speed. I recommend others to go for Rail wire express network, If you have feasibility.
