Re: Cisco 1841 connected to cable modem - slow performance

Where exactly is the speeds slow, or are you wanting to make sure you get the full rated speed of your line?

See here to start : »[HELP] Cisco 800/837 Slow Upload Speeds Various Download Speeds
for some basic troubleshooting to verify your speeds.

Does the 1841 have a VPN accelerator card?

The post was moved, thank you. (First post and it shows)

Yes the router has an AIM card installed.

Thank you

I will take a look at the post. Yes the router has an AIM card installed.

Yes I want to make sure we can get at least 65-75% of the rated speed.

Thank you

First things first, what, if anything, jumps out at you if you run "show log" ?

I'm pulling 12Mbit through my 1841 downloading a torrent as we speak. CPU usage is hovering around 41-51%, mem is at 22%, and I have three VPN tunnels open.

I have checked the log several times and nothing, but CBAC entries exist. Average CPU is less than 10%. I have the VPN setup but I do not have it running through the ethernet port, just the serial. Both ethernet ports are clean with no errors at all.

I am in the midst of testing the cable service but I cannot seem to get even 50% of the rated speed. AT this point I am at a lose as to what it could be.

But if you connect directly to the cable modem, bypassing the router you get the rated speed?

What is the output of the command:

sh int fastethernet0/1
 

Please paste it in the thread.

I am plugged directly into the cable modem. I think I found the issue. I was using IE8 to perform the test and on a whim I downloaded Chrome and the speeds where up in the 11+ mbps download and 2.5 mbps for upload.

At this point I am going to say the issue was the browser and not the config. I appreciate the assistance!

I posted the stats for both FA0/0 and 0/1.

Thank you for all that assistance!
