I got the 128k ul airtel connection in early dec. late dec, my daytime speed drops to 40-45kb/s. night time is 75-80kb/s. so after some complaining and no response, I switch to 64k ul. Here I get 45k. After airtel's new plans come out, I move to 256k 1gb. 3 days after switching, the speed during the day goes down to 80-140k during the day. during the night(after 1 am) it is 180-200k. Having had enough of this airtel bulls*it, I moved to bsnl and am quite happy now.I talked to airtel technical about these problems and they said that speeds are UPTO 64k, 128k, and 256k. They do not guarantee you will get the full speeds.
