Troubleshooting Tips
Problem: I cannot access the Internet. What should I do first?
Solution: Try the following:
¾Make sure that your Cable Modem/Router’s MAC address is registered with your cable
provider. When your provider’s representative or setup software asks for your MAC
address, you can find the CM MAC address on your modem/router’s bottom label. If
you are having a problem, you may need to check with your cable service provider to
make sure the service provider set up its system properly for your cable modem.
¾Make sure your Cable Modem/Router’s plugged into a live power outlet.
¾Check your Cable Modem/Router’s Ethernet and coaxial cable connections. Make
sure the coaxial cable is tightly connected. If a computer is plugged into an Ethernet
port, make sure that the cable is plugged in all the way on both ends.
¾If you are using wireless, check that your wireless connection is functioning correctly.
Check the section below, “I am having trouble connecting my computer or other device
wirelessly to the Cable Modem/Router.”
¾Power off your modem/router for at least 10 seconds and then power it back on.
¾Restart your computer or other devices connected to the Cable Modem/Router. This
ensures that they receive a correct IP address from the router.
Problem: I cannot access the Internet. My Power light is on, my Downstream and
Upstream lights are on or blinking, and my Online light is on.
Solution: If you are using your computer’s Ethernet port, check that there is a good connection
between your computer and the modem/router’s Ethernet port. Check that the light
for that port is on or flashing.
If you are using wireless, check that your wireless connection is functioning correctly.
Check the section below, “I am having trouble connecting my computer or other device
wirelessly to the Cable Modem/Router.”
Solution: Try the following:
¾Check to see that your cable TV is working. If it isn’t, contact your cable service
provider. There may be a bad connection to the cable to your home or location.
¾Check with your cable service provider to make sure that your cable data service is
available and running.
¾In some cases, the cable signal may be weak or noisy. If possible, see if the cable
modem/router works better when it’s connected as near as possible to where the
coaxial cable comes into your home.
¾If you have a splitter between the cable modem/router and the wall, remove the splitter
and connect the cable modem/router directly to the wall. A splitter is a small device
that has a single coax cable on one side and 2 coax cables on the other side. If this
fixes the problem, you may need to get a better splitter.
¾If the problem persists, you may need to ask your cable service provider to check the
signal quality on your cable connection.
Problem: I am having trouble connecting my computer or other device wirelessly to the
Cable Modem/Router.
Solution: Try the following:
¾Verify that you can access the Internet with a computer or other device connected
through an Ethernet cable to one of the LAN ports of your cable modem/router.
If you cannot, try the steps outlined in the previous troubleshooting tips.
If the wired computer can access the Internet, reboot the wireless device (this will
allow the device to release and renew their IP addresses) and try to access the
Internet again.
If you still cannot connect to the Internet wirelessly, continue below.
¾Check the wireless security settings on the wireless device and verify that your device
is using the same wireless security and password as the Cable Modem/Router. The
default wireless settings can be found on the bottom label of your router. The settings
on your computer, phone, or other device must match the modem/router settings –
either the default settings or some new settings you made.
¾Check the signal strength of your wireless connection. Most wireless adapters have
some type of signal strength meter that shows how strong your wireless signal is.
Windows users, click the Wireless icon in your system tray to check signal strength.
If your signal strength is not strong enough, try reorienting the antennas on the Cable
Modem/Router.
¾Change the wireless channel. To do that, follow these steps:
1Open the Zoom Configuration Manager by entering the following in your Web
browser's address bar: http://192.168.0.1
2In the Login dialog box, type the following User Name and Password in lower
case, and then click Login.
User Name: admin
Password: admin
3Click Wireless on the menu bar to open the Wireless page.
4On the Radio page, from the Control Channel drop-down menu, select a channel
that is 5 channels away from the current channel you are using. You may need to
switch the Sideband for Control Channel setting from lower to upper to access
the higher channels.
5Be sure to click Apply after you change the channel. All devices connecting
wirelessly will automatically switch to the new channel.
¾If changing the wireless channel did not help, you should reduce the amount of
bandwidth your wireless connection is using from 40 Mhz to 20 Mhz on the same
wireless page.
¾Move the device trying to access the Cable Modem/Router to a different location,
ideally closer to the Cable Modem/Router.
¾If possible, move the Cable Modem/Router to a new location, ideally closer to the
wireless device.
¾For some computers and some tablets, try deleting the old network settings including
the SSID and password/pre-shared key. After you do that, use the new settings.
Normally the new settings should be the modem/router’s default settings as discussed
above.
¾Refer to your computer’s or other device’s documentation if necessary.
Problem: I don’t know my Cable Modem/Router’s SSID or Password.
Solution: The default values are printed on the bottom label of the modem/router.
If you have changed these values, connect a computer to any Ethernet port of the
modem, open the computer’s Web browser, enter http://192.168.0.1 into the
browser’s address bar, and press ENTER to go to that address. When the
modem/router’s user interface comes up, enter admin for both the username and
password. Go to the Wireless section to find the SSID and password (also called
Preshared Key or Passphrase).
Problem: What do I do if my cable service provider wants me to access the Configuration
Manager?
Solution: Make sure you have a connection between your computer or other device and the
cable modem/router.

browser's address bar: http://192.168.0.1

Problem: What if I'm told that my Model 5363 cable modem/router isn't approved for my cable
modem service? ®
Solution: This product has been certified by CableLabs , the cable service provider’s primary test
lab. However, some cable service providers have their own certification process. To see
whether model 5363 is certified by your cable service provider, you should be able to
check your service provider’s Web site or to speak with someone from your service
