Comcast speed testing

Recommended Posts

There must be something going on at Comcast cable.

My Gold High Speed connection increased over the weekend from 5000Kbps to 5200-5500Kbps download. I observed similar speed increase just before the last speed increase in April.

Interestingly, the Testmy.net speed remains the same.

Well lately, past 3 weeks or more, I have had a serious decrease in download speed. I have the upgraded package 6Mbps up 768Kb up. My upload has gotten a lot better, around 86 KB/s...but download is horrible at about 116 KB/s when around 3 to 4 weeks ago was at least 550 to 700 KB/s. I read a post on another forum earlier today http://www.broadbandreports.com/forum/remark,13580077 talking about how comcast made a CRAN upgrade last month and a guy from that post had to get another modem from comcast that helped boost it back up some. Maybe you got a better end of the stick haha

True, but the thing is, I have done tweaks with cablenut and a couple other programs as well and the only thing that seems to have gotten better recently is my upload. Like i said, its been going on for 3 weeks or more. Same thing happend to a friend of mine on the other side of town too as well as other people in my area from what I have seen on a few different forums. I think tomorrow or the next day I am going to call comcast and see what they say about it

Comcast told me i'am now at the 6mbs level in the Philadelphia suburbs. So far I haven't got beyond 4.9mbs down. The comcast tech came out switched the SB4100 with a SB4101. I had ask him to give me a SB5100 but he said they were out of those. I still haven't pasted the 4.9mbs level but the upload improved from 374 to 703. The tech said it could be a weak signal problem. My modem downstream SNR is 37dB...PL -1dBmv. The upstream PL is 50dBmv. Comcast is sending out another tech to verify the signal strength in a few days. Comcast has already dropped a new cable & installed a new amp in the pedestal then switched to a new splitter. I think I'll buy a SB5100 from BestBuy...when the tech comes i'll let him try that modem to see if this is really a modem issue. I've tweaked  RWIN ..MTU with different variations but nothing gets me into the middle 5 to 6mbs range. They said the cap is at 6.6mbs.

Any input would be welcomed  :-P
