That means you probably have Hathway only. Is it the 50mbps one?
I have no idea about the reliability of Hathway. I think its upload speed should be equal to DL, not sure. Though the FUP is lower than even Airtel. And you have to pay for 3 months, with extra installation.
You can try calling Siti (50mbps no FUP for 850, UL is 2mbps) or Verivoz if you haven't. Don't know about their reliability too but plans seem good.
