This is soo annoying. I just hooked up a tv to the living room where my computer is at, so I can watch tv and surf the net at the same time, and now my cable modem always disconnects. It's so annoying when I'm trying to surf the net and it disconnects. Here's what docsdiag tells me:

External Ethernet Cable Modem VENDOR: D-Link Corporation HW: 3.2 SW: 4.4270

Downstream channel ID = 0
Downstream channel frequency = 573000000 Hz
Downstream received signal power = 0.0 dBmV (or not supported)
Upstream channel ID = 3
Upstream channel frequency = 30992000 Hz
QoS max upstream bandwidth = 256000 bps
QoS max downstream bandwidth = 3000000 bps

Upstream transmit signal power = 58.0 dBmV

My area is having problems with the cable modems blinking, but it says on the Roadrunner Help page (http://help.rr.com) that my area's problem has been fixed but it hasn't been for me. Can someone tells me what to do? It's annoying and it disconnected just now. Someone tell me what to do for the disconnects? I'm trying to browse dslreports, speedguide, the net and watch tv at the same time, but I can't because my cable modem just disconnects:( I'm ready to throw this cable modem out the window. As soon as we can fix the disconnects, I can watch "The Simpsons", etc at the same time and surf the net:D

Is the TV on the same leg as the modem?

The Upstream transmit signal power = 56.7 dBmV is a little high! It should be below 54dBmV. It shouldn't affect your speeds or connection as long as it doesn't go any higher. I wonder what the Downstream signal is at? The Signal to Noise Ratio = 30.6 dB
looks really good.

I guess all you have to do is sit back and enjoy it. Hopefully it will stay that way.

Well, it stayed, and now I can watch tv and surf the net at the same time:):) "In The Heat Of The Night" at 10pm on WGN and "I Love Lucy" on 3pm on TvLand for me:p

Some usb dsl/cable modems may get disconnected after a little while. A possible reason that could cause this problem is that in windows xp there is an option that allows the computer to turn off a usb device to save power. To disable this option:

1) click start, highlight my computer, right click and select properties and a window will pop up with the system properties
2) click on the hardware tab and press the device manager button
3) expand the universal serial bus controllers
4) Double click on the USB Root Hub.
5)Select the Power Management tab and UNTICK the "allow the computer to turn off the device to save power"

If you have more than one USB Root Hub, then you should apply the steps to each one of them
That's it, you won't need to restart the computer!

With some ADSL/Cable modems (especially USB) you may have a problem with getting disconnected after a few hours, here are two ways to fix that.

Disable Hibernation
Right click on your desktop, click the screen saver tab, once there you should see a power button at the bottom of the display properties dialog, click that, ones dialog appears click the hibernate tab, and uncheck enable hibernation.

Disable Windows Messenger
Go to your start menu, click run.
In the Run dialog type gpedit.msc
Go to Computer Configuration>Administrative Templates>Windows Components>Windows Messenger
Once there right click Do not allow Windows messenger to be run, go to properties.
Check the box next to enable.

That should fix the problem.

Are you losing sync or all of a sudden can't browse the web?

On the next occurance, type IPCONFIG /ALL (for 2K/XP) at a command prompt or type WINIPCONFIG (95/98/ME) in a run box and note the IP address. If it's 165.x.x.x, you're losing your lease for some reason.
