If I bypass the AirPort Extreme router and connect directly to my cable modem I enjoy 121 Mbps speed. Going through the AirPort Extreme I can barely get to 10 Mbps. Any ideas on how to configure it to be faster?
I've restarted it 1,000 times. I had success speeding it up yesterday when I restarted the modem plugged into my iMac and then did the same plugged into the AirPort Extreme. That lasted one day.

We need a bit more information from you to try to start the troubleshooting process.
Is this a new "tower" version of the AirPort Extreme? If not, which model number do you have?
What is the make and model of the modem?
What operating system are you using on your Mac or PC?
Sorry...
I bought it on 9/30/14 and it is the tower version. I'm using an Arris SURFboard SB6183 DOCSIS 3.0 cable modem. The iMac that I use the AirPort Utility on is running OS X 10.10.2.
Thanks for any help you can provide!
So, did the AirPort Extreme work OK with the same modem before, or was there a modem change recently?
Unfortunately, there are a number of posts about compatibility / speed issues with the Motorola modems. In addition to the SB6813, the SB6141 appears in a number of posts. Personally, I had issues with the SB6141 when I needed a new modem about a year ago, and despite trying several different samples, the issue was not resolved until I tried another brand of modem that the ISP recommended.
AirPort Utility in OS X (10.10.2) no longer has any type of manual settings for the WAN port on the AirPort Extreme, so there is not a lot that you can do.
I would first try resetting the AirPort back to factory default settings and then set it up again to see if that might solve the issue.
Otherwise, you could try inserting an Ethernet switch between the modem and AirPort Extreme. The switch might "talk" to the modem better is the thinking here, which has helped some users with this issue.
Another thing that you could try is a crossover Ethernet cable between the modem and AirPort Extreme,
hi chip, did you ever find a solution? i am having same issue with my SB6183 and airport extreme...
followed instructions to reboot the SB6183 and reset and reconfigure the airport extreme and now I'm getting 340 mbs down and 350 mbs download wirelessly
My AirPort Extreme is slowing the internet to a crawl
