Modems & Troubleshooting

  • If you have Midco business wired/cable internet equipment, a professional Midco technician will install a standard modem provided by Midco. If you opt to provide your own equipment, a trained Midco Business service technician is required onsite to install all equipment – and ensure all services are working properly.
  • If you have a fixed wireless business connection, a professional Midco technician will install an antenna at your business. You'll need to purchase or use your own router. Visit our fixed wireless support page for details on how this internet delivery works. (Fixed wireless internet is available in select areas.)

Approved Modems

You'll need a cable modem from Midco to connect to the internet; however, some modems are not compatible with our network. For technical reasons, we can only offer service through approved modems. That's why we've compiled a list of approved modems that will ensure the best quality of service and get you connected.

We are continually improving our speeds, so we strongly recommend a DOCSIS 3.0 modem for the best experience. Note: you must have a DOCSIS 3.1 modem in order to reach the higher speeds for Midco Internet 500 or Midco Gig Internet. If you have questions, please contact customer service at 1.800.888.1300.

If we don't provide a specific modem that you're looking for, including all wireless modems, then it must be purchased from a separate vendor. Midco will not support wireless functionality or features for any wireless modems purchased.

If you also have or are considering using a router, please review important router information.

Modem Reboot

You may periodically need to reset your modem to clear outdated or invalid network information, which may help the modem process information more quickly – similar to why it’s recommended that you restart your computer or other devices from time to time.

To reboot your cable modem:

  1. Unplug the small, black power cord from the back of the modem.
  2. Check the front of the modem to ensure that all the lights have turned off.
  3. After 30 seconds, plug in the modem.
  4. Wait for modem lights to be fully lit (not blinking).
  5. If you have a router connected, reboot that equipment as well.
  6. Once power is restored, wait five minutes for the modem to come back online. Test the connection again by attempting to access a public website such as

If you need additional assistance, please contact us.

DOCSIS Technology

DOCSIS stands for Data Over Cable Service Interface Specification. This means that the modem conforms to international standards required for proper connectivity. In this case, you'll need a modem that conforms to 3.0 standards. These modems support Internet Protocol version 6 (IPv6), which is essential for connecting to our network. To enjoy faster Internet speeds, more advanced equipment such as the DOCSIS 3.0 modem is required.

While the DOCSIS 2.0 modem may still work for your business needs, please note that the equipment does not support higher speeds. For instance, an older 2.0 modem will limit your capability to get the speeds associated with even our basic internet package.

The DOCSIS 3.1 modem is required for gigabit internet speeds

How to Get a Modem

Midco leases modem equipment for new and current customers using wired/cable internet. Your Midco modem will always be an up-to-date model so you get optimal speeds for your internet package. As technology advances, we’ll update the equipment for your business, so you don't need to use your own modem or worry about keeping it updated.

  • If you’re a new customer, you can lease or purchase a non-wireless modem from Midco as a part of your contract. Whether you order online or over the phone, a Midco representative will discuss your business needs with you to help you select the best modem for your business.
  • If you’re a current customer and need new equipment, contact customer care, as changes in equipment may affect your network setup.
  • If you want to bring your own modem, make sure it’s one that’s been tested on the Midco Network. Review our Approved Modems list on this page. Again, if you already have Midco services, please contact us to ensure the proper setup.

Best Modem or Router Location

An expert Midco technician will provide advice and guidance on the best placement for all equipment when services are installed in your business.

The further you’re away from your modem (or your own, third-party Wi-Fi router), the weaker your signal. This can be even more challenging if you place your wireless modem in a faraway room, as your building’s size and materials also impact signal strength.

If have a Midco-provided wireless modem and want to move it, please contact us, as moving the equipment may impact modem settings established by the Midco technician during installation.

Modem Power Light Off

If your modem light is off, there is no power going to your modem. Check all the cables on the back of your modem. Make sure they are plugged in tightly, and that the power pack is plugged into the wall outlet.

If the light is still off, try plugging the modem into a different wall outlet. If you still do not have power to your modem, contact us.

Modem Online Connection Light Flashing

Try to reboot your modem. If you cannot connect to the internet or you have to reboot your modem often, contact us so we can make sure your modem is functioning properly.
