We have listed some various types of issues you may encounter with home
networking along with links that provide information to the best way to resolve the issues. You may need to try more than one solution to resolve a specific issue.

None of my computers can connect:

1. Check your modem to verify that all cables are plugged in and there are no loose connections. Verify that your modem has block sync as well.


2. Verify that the hub, switch or wireless access point is properly
   connected.


3. Does your hub, switch or wireless access point have an uplink port and is
   the CAT5 Ethernet cable connected from it to the cable modem? Try a different
   piece of CAT5 cable. A hub, switch or wireless access point without an uplink
   port requires a special cross-over cable.


4. Do your computers have a Mediacom Cable Internet Services IP address? Try
   a release and renew.


5. If you still have connection issues, check to see if your computers can
   connect directly to the cable modem without your central home networking
   device (hub, switch or wireless access point).

1. Check the computer that will not connect for loose connections.


2. Try a different port on your central home networking device (hub, switch
   or wireless access point) and release and renew.


3. Try a different cable and release and renew.

1. Verify that the hub, switch or wireless access point is properly
   connected.
2. Does your home networking device have an uplink port and is the CAT5 cable
   connected from it to the cable modem? Try a different piece of CAT5 cable. A
   hub, switch or wireless access point without an uplink port requires a special
   cross-over cable.


3. Try other known working pieces of CAT5 cable to connect your computers to
   the hub, switch or wireless access point.
4. Do your computers have a Mediacom IP address?
   Try a release and renew.
5. Try other ports (if available) on your home networking device.
6. If the above steps fail and if you are using the same cables that provide
   a proper connection when connected directly to the cable modem, replace the
   hub, switch or wireless access point for your home networking equipment.

1. First, ensure that your Cable Modem is connected to a power source and
   that the modem lights indicate normal service. Read the documentation supplied
   with your modem to view the normal state of the LEDs.
2. If the modem lights are flashing or are not in a normal state, powercycle
   the modem by disconnecting the power cord from the modem.
3. After 45 seconds have elapsed, reconnect the cord; the LEDs will cycle and
   should return to their normal state within one or two minutes. If your modem
   does not return to a normal state, you will need to contact customer care.
   
4. Note: If you just performed a new installation of multiple computers, even
   if your modem lights indicate it is in a normal state, you should powercycle
   after receiving e-mail from Mediacom verifying your account has been
   configured for multiple computer access. Please do this as a first step and
   recheck any connectivity issues.

1. Before proceeding to detailed problem solving, it is a good idea to
   verify that all Ethernet cables are firmly connected to each computer, the
   central home networking device (hub, switch or wireless access point) and the cable modem.
2. Check all power cords for all computers, as well as the networking equipment and the modem.
3. Release and Renew the Ethernet Adapter
4. Follow the instructions for your operating system to release and renew the adapter.

1. Disconnect all CAT5 Ethernet cables from the computers.
2. Disconnect the CAT5 Ethernet cable from your cable modem and the hub,
   switch or wireless access point.
3. Connect the first computer with a connectivity issue directly to the cable modem using a CAT5 Ethernet cable that is known to be in good working order.
4. Perform a release and renew for your operating system.
5. If unsuccessful, try restarting your system.
6. If still unsuccessful, try a different length of CAT5 Ethernet cable. If at this point you are unable to connect to the Internet, you'll need to contact customer care. Before you contact us you should verify whether or not you can successfully connect to the Internet from the other computers by following the above steps.

1. Using two CAT5 Ethernet cables that are known to be in good working order, connect one CAT5 cable to the uplink port and the cable modem, then connect the second CAT5 cable to one of the available ports.
2. If you do not have a working connection to the Internet, perform a release and renew.
3. If release and renew is not successful, power off and restart your
   computer.
4. If unsuccessful, try other ports on your hub, switch or wireless access point and repeat steps 1-3.
5. If you are still unable to connect, you should replace your hub, switch or wireless access point.
