My boyfriend has Comcast and his upload speed is constantly 45k/s or less, while his download is normally not too much higher. He had a tech come out to his house. Here's what the tech told my boyfriend, almost verbatim.

"You know how cell phones roam? Your cingular phone works fine when it's within range of a Cingular tower, but once it has to use an Sprint tower it goes to bleep. It's the same thing with internet connections. If your computer is using another ISP's servers, you're not guaranteed the internet connection that we offer."

This sounds very off to me. How much truth is in this?

No. What he told you is not accurate. What security programs do you have? Antivirus, antispyware, firewall,..

I don't see it as entirely inaccurate, just a bad way of explaining it.


Disadvantages: An obvious disadvantage of cable modem service for rural communities is the lack of cable service beyond the edges of the larger towns. Another disadvantage is that the connection speed may vary greatly at different times of the day. Residents in neighborhoods where cable modem penetration is high may notice a significant increase in the time it takes to upload and download information in the evening when people return home from work and school. Another disadvantage is that upload speeds never match download speeds. - (Link)

I use Comcast and have never had it that slow. Seems like there should be something they can do.

From a tech:

They could do things like node splits to make the nodes smaller. They could also change downstream and upstream modulation schemes to get more bandwidth.

Also:

Also try doing a ping -t xxx.xxx.xxx.xxx where this is the Cable Modem's router. Then try it against Yahoo.

If the first is slow, then there could be an issue on your local loop.
If the first is fast but the 2nd is slow, there could be an issue on one of the routers a bit further out.

I would run the tests and then contact comcast with the results.

There isn't a router. There is only one computer hooked up wired.

Though you may not have a router, your ISP uses routers. There may be several routers between the file you are trying to download and your computer.

This isn't something that happens sporadically. It happens all the time. and how do i find out the IP to one of comcast's routers?

Go to Start > Run

In the box, type cmd and hit enter.

At the prompt type:

tracert www.yahoo.com

Then hit enter. Watch the results, and you can see the various routers it will go through to get to yahoo. You should see "comcast" written next to some of the results. It also shows the latency in and any packet loss.

Comcast.net was slow, Yahoo was fast, and so was comcast.com. My boyfriend says "I could understand them capping P2P, but EVERYTHING is slow. Sending you a picture on gtalk takes a long time." And it's true.

Well, if you are paying for a connection, I would raise heck with Comcast until they fixed it, and you are getting speeds they told you you should get.

That slow of a speed that you described is really unacceptable.

I agree. I just needed to ask someone else. I'm tech but I don't know anything on the ISP's end.
