hi. I have been using Tata VSNL broadband for the past three years. Although there have been major issues the thing with Tata VSNL is that when it works fine its the best but when it gives problems they are really a headache to solve . Well since the last three days i have this problem. The ALM light on my router suddenly goes on and after that i have to disconnect all the cables. Only after that can i surf again. This continues happening after every 10-15 mins. The strange thing is that this problem arises only in the nights and in the mornings. It works fine otherwise. I tried contacting customer care but they say there is no problem from their side. Well i really want to know the purpose of this ALM. What does it exactly mean? My router is XAVI x8821r+.
