Slow download speeds

Recommended Posts

Hi about a month ago I started having all these download speed problems where nothing would ever hit above 60ks/s with one thread and if i did use multiple threads i could only do up to about 3 to maintain that 60ks/s on each thread. I'm using Comcast and I'm supposed to be getting 3mbit download speeds. Now the funny thing is this problem started last month, I just moved 3 days ago, got the internet hooked back up and they even gave me a new modem now once I installed the new modem I had to download the Comcast Installation Wizard from there site. That downloaded at a full 395ks/s BUT once I installed the kit and reset my modem and everything (because it's a new modem for my account) all the sudden I get my horrible download speeds again. Now my brother who lives just around the block from me has no speed problems at all and the Customer Service at Comcast claims that it HAS to be something on my side.

Now what doesn't make sense is, how is it that before I had my modem setup and ran their "Comcast Installation Wizard" I hit my full speed and once it was installed my speed went to crap. I ran multiple tests on DSLreports and got no more than 600kbps on my download. Here's the results I got from TestMy.net:

Trace complete.

The modem is plugged directly to my Ethernet card, the ethernet card is made by Kingston which is a decent brand from what I understand, I never had any problem before until I woke up one morning and had all these problems. I'm running Windows XP Pro SP2, 512MB ram and I haven't changed anything on my computer in a long time. The modem I used before was a Motorola SB5100 and never had any problem until all of the sudden that one day came around. Now I'm using a RCA model DCM425.

Solutions I've tried:

Changing modems AND the cables

Uninstalling my Ethernet card and letting WindowsXP find it again

I noticed in the pathping there was a whole bunch of hops with 100% loss and I have no idea whatsoever is causing this, any help is HIGHLY appreciated as the comcast customer service people can't offer any help to me at all. Thank you :)

hi mikero and welcome to the forum :hello:

it looks like:

12.123.13.154

12.122.11.93

12.122.10.26

12.122.10.49

12.123.196.101

70.85.127.61

70.85.127.83

all block pings, so thats not a problem on your end...

go to start-run-cmd, type ping 12.119.136.14 -n 100 and paste the results here...

are you currently using any tweaks?

Your low speed could also be a problem due to recent upgrades and testing in your area also...

thank you for the welcome and fast response..well after i had made this post my brother suggested to me that i try plugging the cat5 cable into the ethernet on the mobo instead of using the one i have plugged into the PCI slot and it worked! My speeds are completly fine now but I still don't understand what went wrong with the other one that I've used forever so I went to switch back to the other ethernet so I could run that IP that you asked me to and now when I plug it in it says limited or no network activity. I'll try fiddling with it a bit and try to get it working, I kind of prefer using the other one because using this one on my mobo changed my IP and i have a static IP and now I have to change a lot of my things if I have to use a new IP.

edit: hmm but even when i did a pathping with this ethernet i still had the same loss on those same IPs

edit2: god nevermind looks like this connection starts high and then just drops allll the way down again for some reason..this is very frustrating
