Incredibly Slow Internet

Question

My time capsule has been pretty reliable until recently the internet has painfully slow. I think it may just be Charter because their service has always been spotty. I even had them out to my house and they couldn't do anything to make it faster because the guy they sent was not familiar with macs.... (i hate charter)
Is there anything I can do to find out what the problem is? Charter gave me a replacement modem to see if that changed anything because the other modem was ancient (nothing has really changed; if anything its gotten worse). Even my xbox 360 which is maybe 10 feet away from the time capsule has terrible connection. Any help is appreciated.

There are several steps you can take to isolate the problem.
One is to connect your modem directly to your computer to see if the internet connection is still slow. If so, the cable signal is at fault. Before you do this, you will need to reset the modem by powering it down for at least 30 minutes. Pull the battery in the modem if it has one as well.
Shut down the computer. Power up the modem first and let it run for at least 5 minutes, then power up your computer to test the internet connection speed. If you get a good connection, the next step is to reconnect the modem to the Time Capsule. Remember to completely reset the modem as mentioned above before you do this. Power off the Time Capsule and power up the modem first and let it run for 5 minutes. Then power up the Time Capsule for a few minutes and finally your computer and other items.
If the speed slows noticeably in this configuration, you should reset the Time Capsule back to factory defaults and reconfigure the device. If still no luck, you should have a repair shop check out the Time Capsule for proper operation.
Remember that you will always need to completely reset the modem any time you connect it to a different device.
