Well...I changed from UL1350 Plus (always 512kbps) to this one because they hadn't upgraded my connection to ULF 1350 (2Mbps for first 20GB) one. So I thought of shifting to ULF1400 and back to ULF 1350 as the BSNL computer operator for plan changing stuff showed me that I was already on ULF 1350 (and not Unlimited 1350 +) and couldn't select that one to change to.Anyway....When the plan did get changed last month, within 3 days of applying, the Link rate downstream was around 2Mbps ( didn't check the upstream though). I called the BSNL office and they told me to wait till new month(December) and it would get sped up. And it actually did change to around 4Mbps from December 1 (as can be seen in the screenshot).This is why I'm suspecting some settings at my end might be the culprit for low upload Link rate.
