6 Mbps = how many KBps?

famosbrown · May 27th, 2006, 12:45 PM

I have Comcast, and I'm always over my 6mbps. I use testmy.net to test my download speed and it is sometimes at 8mbps, but never at or below 6mbps. Also when I am downloading something from a site, depending ont he alloted bandwidth allowed by that particular site, I download 900K and even over 1mb. I would have Comcast come and check your signal. Also it all depends on how many people in your LAN. If a lot of people are using Comcast, the bandwidth is shared. But for me, during peak hours, I'm still a little over 6mbps according to testmy.net.

So for me anyway it looks to be the ISP that is slow.

You can try manually bump your receive window to higher scale factor, such as 513920.

Otherwise, it certainly does look like your connection has hit a peak limit. If you are paying for a 6Mbps connection, then I would suggest re-evaluating your ISP. The problem could also be your cable modem, but I doubt it if the modem is a brand name model.

Potential physical problem spots you can check include: poorly shielded coax, deteriorating coax, extremely long coax run, upstream line splitters, poorly attached connectors, and poor grounding.

Is comcast still restricting usenet access?

Download Speed: 4481 kbps (560.1 KB/sec transfer rate) / 5.0Mbps advertised
Upload Speed: 348 kbps (43.5 KB/sec transfer rate) / 350Kbps advertised

I used similar programs back when I had dial-up and never did see any difference. Maybe it works better with broadband.

Correct. Windows has a large enough default receive window for dialup, so TCP/IP tweaking makes for little difference.

Well I have about a 70ft coax cable going from the splitter upstairs then outside and through the basement vent were it hooks up to another splitter for the tv downhere and the cable modem. I do not know if that affects anything or not. I do remember downloading at around 300kbs before I put the modem and router in the basement so I still think I had the problem even then. Although my connection was rated 3mbps connection back then as well so I dont know. We have had services guys comeout and they all said everything checked out fine. I have also called a billion times and they said that the modem checked out fine and that it was the routers fault. I direct connected to the modem and it was still slow so obviously its the ISP but I do not know what else I can do. I can call them again and have a tech come out but they will still say everything is working fine and since I live in a fairly small city of aroun 80,000 people there is not much competition for Comcast which is why my connection is so limited. They probably share the 1 connection for every single resident in the city or something.

Mistakes do happen. About 2 years ago my ISP was servicing equipment in their main office and for some reason turned down our adsl speed from 1.5Mbps to 768k and left it that way for about 6-9 months and didn't know it. Even after writing a letter to the vice president of the company nothing changed. Then my router got fried in a storm and I had to take it to the office for exchange. While at the office I mentioned it to the manager and he seemed doubtful that I was only getting 768k but said he would check. By the time I drove home the speed was once again 1.5Mbps. and I was

Ok, I guess I can have the service guys come out again. I will give them a call and see what happens. Probably wont be able to get a guy to come out here today but if I can get a faster speed I am all for it.

EDIT: Sorry for hijacking your thread Tramp429.

They already increase my speed. Noticed it this morning so I used TCP Optimizer to tweak the connection and it gave me another 150KBps+ . Been averaging 836 KBps for an hour or so now.

I have this service from Quebec called Videotron.....we're supposed to be getting something like 6.5 mbps (so like 750KBs) but im almost never there, I'm always getting something like 900KBs or higher.....I max out at about 1100KBs which is when I download torrents......so what thats something like 9mbps?

it could also be because I live on a street where most people are at retiring age.....and most people around me dont have internet, or just don't use it like I do
