Ok so connection is fine since 7-8 days except since last night when I got the limited or no connectivity error, its been fixed now.
So had taken an off today, and spoke to the engineer at length apparently he said my issues were not new in the area, there were cases when the net was down 15 days a mth for some users!!! Hopefully I am not that unlucky.
Connection is fine right now, except my upload is capped at 40 kbps (5kBps upload speed) the engineer said, for my connection the upload speeds would not be the same as download speeds but 40 kbps cap on a 300 kbps connection does not make sense, I have spoken to his senior who said he will look into the matter....
The only reason I am continuing with the service is the customer service is excellent!! they will always send a man on weekdays after 1-2 hrs of calling the customer support. unlike the local cablewallas who switch off the cell in case something goes wrong...
