UPDATE: the demo guy came again, checked for signal, did some speed tests, it wasn't going above 3.5mbps in the results, but it was touching ~3.8mbps during the test (the demo account is on a 4mbps plan i believe) , but he said that no ones speed actually stays at a constant 4mbps, it's only sometimes that you get the rated speed. Is that true? BTW the tower is quite far, around ~450m from my place, but it's still visible from my terrace. Pings were around ~10ms more than the ones posted here, sometimes even matching them, gotta be fluctuations but i'm okay with it since BSNL gives me 250-500 ping in any server outside india -.-So the connection was stable at the time, wasn't disconnecting or anything, he said he'll install it as soon as new equipment arrives, lets see how it goes and how long they take to acquire the new equipment.
