Key Takeaways
- TDS-provided modems arrive pre-activated and ready to connect. If you are using your own modem, you must call TDS at 1-877-422-5282 to activate service before setup.
- TDS delivers internet through three connection types (DSL, cable, or fiber), and each one has a slightly different physical setup process.
- TDS home phone service in cable areas requires a TDS multimedia modem. In DSL areas, phone service uses your existing telephone wall jack and wiring.
How to Activate a Modem With TDS Telecom Internet
Setting up a new TDS Telecom internet connection does not have to be complicated. Whether TDS sent you a modem in a self-install kit or you purchased your own, this guide walks you through every step of the activation process. We also cover how to activate TDS home phone service if you have it bundled with your internet plan.
TDS Telecom delivers internet through three different technologies depending on your area: DSL, cable, or fiber. The activation steps vary slightly for each type. If you are not sure which one you have, check your order confirmation email or call TDS at 1-855-244-0122.
Before You Start: TDS-Provided vs. Your Own Modem
This is the most important thing to know before you begin. If TDS sent you a modem (either in a self-install kit or through a technician visit), it is already pre-activated on their network. You just need to plug it in and connect.
If you purchased your own modem, you must call TDS at 1-877-422-5282 before setting anything up. A representative will register your modem's MAC address on their network so it can connect. Keep in mind that TDS does not provide technical support for customer-owned modems, and if a technician visit is needed to resolve an issue caused by your own equipment, you may be charged a service fee.
How to Activate a TDS Cable Internet Modem
If your TDS service comes through a coaxial cable connection, follow these steps.
Step 1: Connect the Coaxial Cable
Find the coax outlet on your wall (or the splitter if you have one). Connect one end of the coaxial cable to the wall outlet and the other end to the cable connector port on the back of your modem.
Step 2: Plug In the Power Cord
Connect the power cord to the back of the modem, then plug it into a wall outlet. Avoid using a power strip or a switched outlet, as these can cause intermittent power issues that disrupt your connection.
Step 3: Wait for the Modem to Initialize
The modem will begin its startup process. You will see a series of flashing lights on the front panel. Wait until the top three indicator lights become steady. This usually takes two to five minutes.
Step 4: Connect Your Device
You have two options. For a wired connection, plug an Ethernet cable from one of the LAN ports on the back of the modem into your computer or router. For a wireless connection, look at the sticker on your modem for the Wi-Fi network name (SSID) and password (Preshared Key). On your phone, tablet, or computer, open your Wi-Fi settings, find the matching network name, and enter the password.
Step 5: Test Your Connection
Open a web browser and visit any website to confirm your internet is working.
How to Activate a TDS DSL Internet Modem
TDS DSL service is delivered through a telephone wall jack. Typically, only one jack in your home is wired for DSL, and it is usually located in a living room, den, or office.
Step 1: Connect the DSL Cable to the Wall Jack
Take the DSL cable (usually gray, and it looks like a standard phone cable with a smaller plug) and connect one end to the port on the back of the modem labeled "Phone" or "DSL." Connect the other end to the telephone wall jack that is wired for DSL service.
Step 2: Install DSL Filters on Other Phone Jacks
If you have landline phones or other devices (like a fax machine or satellite TV receiver) plugged into other phone jacks in your home, you need to install a DSL filter on each one. The filter plugs into the wall jack, and then your phone plugs into the filter. Do not put a filter on the jack that connects to your modem. Skipping this step can cause static on your phone line and interfere with your internet connection.
Step 3: Plug In the Power Cord
Connect the power cord to the back of the modem and plug it into a wall outlet. The Power indicator light should turn on immediately. After a short wait, the DSL light should turn on, followed by the Internet light.
Step 4: Connect Your Device
Use an Ethernet cable to connect your computer to one of the yellow LAN ports on the back of the modem. Do not plug anything into the white WAN port. For wireless connections, use the Wi-Fi network name and password printed on your modem's sticker.
Step 5: Verify Your Connection
Open a web browser and navigate to any website. If all three indicator lights (Power, DSL, and Internet) are steady green and you can load a webpage, your modem is activated and working.
How to Activate TDS Fiber Internet
TDS fiber service works differently from DSL and cable. With fiber, there is no traditional modem. Instead, TDS installs an Optical Network Terminal (ONT) in or outside your home at no cost. The ONT converts the fiber-optic signal into a standard Ethernet connection that your router can use.
Step 1: Confirm Your ONT Is Installed
A TDS technician must install the ONT before you can self-install your router. If you chose self-install and your home has never had TDS fiber, a technician will visit to set up the ONT and run fiber to your home first. The ONT must already be present and powered on before you proceed.
Step 2: Connect Your Router to the ONT
Use an Ethernet cable to connect your wireless router to the ONT. TDS recommends using a Wi-Fi 6 capable router for the best performance. If you are renting a router from TDS, follow the setup instructions included in your self-install kit or use the TDS app if one was provided.
Step 3: Power On Your Router and Connect
Plug in your router, wait for it to fully boot up, then connect your devices to your Wi-Fi network using the credentials on your router's sticker or documentation.
How to Activate TDS Home Phone Service
TDS offers home phone (landline) service that can be bundled with internet. The activation process depends on whether you are in a cable or DSL service area.
TDS Phone Activation in Cable Service Areas
In cable areas, TDS home phone service requires a multimedia modem provided by TDS. You cannot use your own modem for phone service. The phone functionality is built into the TDS modem. To set it up:
Step 1: Complete your cable modem setup using the steps above.
Step 2: Locate the telephone port on the back of the TDS multimedia modem.
Step 3: Connect a standard phone cable from the modem's telephone port to your corded or cordless phone.
Step 4: Pick up the phone and listen for a dial tone. If you hear one, your phone service is active.
TDS Phone Activation in DSL Service Areas
In DSL areas, TDS phone service runs through your existing telephone wiring, separate from the modem. TDS provides the phone service itself, but you need to supply your own phone (corded or cordless). To set it up:
Step 1: Plug your phone into any active telephone wall jack in your home. Remember to use a DSL filter between the wall jack and the phone if you also have DSL internet.
Step 2: Pick up the phone and check for a dial tone.
Step 3: If you subscribed to voicemail, call TDS to set up your voicemail box, or follow the voicemail setup prompts by dialing your own number from your landline.
TDS Phone Service on Fiber
If you have TDS fiber and bundled phone service, the setup will depend on the equipment TDS provides for your specific area. In most cases, a technician handles the phone service configuration during the fiber installation visit. Contact TDS at 1-855-244-0122 if you need to activate or troubleshoot phone service on a fiber connection.
How to Change Your TDS Wi-Fi Network Name and Password
After activation, you may want to rename your Wi-Fi network to something easier to remember or set a new password. Here is how to do it on a TDS-provided modem:
Step 1: Connect a device to your modem's Wi-Fi network using the default credentials on the modem sticker.
Step 2: Open a web browser and type http://192.168.0.1 in the address bar and press Enter.
Step 3: Log in using the admin credentials printed on the modem sticker. On some older models, the default username is "admin" and the password is "password."
Step 4: Navigate to the wireless settings section and update your network name and password.
Step 5: Save the changes. You will need to reconnect all of your devices using the new credentials.
Keep in mind that changing your Wi-Fi name and password means the default information on your modem's sticker will no longer be accurate. Write down your new credentials and store them somewhere safe.
Troubleshooting Common TDS Modem Activation Issues
No Lights on the Modem
Make sure the power cord is securely connected to both the modem and the wall outlet. Try a different outlet. If you are using a power strip, bypass it entirely and plug directly into the wall. If there are still no lights, the power cord or modem may be defective. Contact TDS at 1-888-225-5837.
Lights Are On but No Internet Connection
Check that all cables are firmly connected. For DSL, make sure the phone cable goes into the correct jack (labeled "Phone" or "DSL") on the modem. For cable, confirm the coax cable is tight at both ends. Try restarting the modem by unplugging the power cord, waiting 15 seconds, then plugging it back in. Wait 30 to 60 seconds for the modem to fully restart and check if the Internet indicator light turns solid green.
Wi-Fi Network Not Showing Up
Make sure the modem has fully completed its startup process (all indicator lights should be steady, not flashing). If the network still does not appear, try a factory reset by pressing and holding the reset button on the back of the modem for 10 seconds. This will restore the default Wi-Fi settings shown on the modem sticker.
Own Modem Will Not Activate
If you are using a modem you purchased yourself, remember that it will not work until TDS registers it on their network. Call 1-877-422-5282 to have a representative activate it. For DSL service, your modem must support the following standards: ADSL2+, VDSL2 (8d and 17a profiles), G.INP, and G.993.5 (G.vector). For cable service, a DOCSIS 3.1 compatible modem is recommended.

Frequently Asked Questions
Do I need to activate a TDS modem that came in my self-install kit?
No. If TDS provided the modem, it is already pre-activated on their network. You just need to connect the cables, plug it in, and wait for the indicator lights to turn steady. Your internet service should come online automatically within a few minutes.
Can I use my own modem with TDS Telecom internet?
Yes, but with some limitations. You must call TDS at 1-877-422-5282 to register and activate your modem before it will work. TDS does not provide technical support for customer-owned modems, and if a service call is needed due to your equipment, you may be billed. If you have TDS TV service, you are required to use a TDS-provided modem.
How long does it take for a TDS modem to activate?
A TDS-provided modem typically takes two to five minutes to complete its startup process after being plugged in. You will know it is ready when the indicator lights on the front stop flashing and become steady. If the lights are still flashing after 10 minutes, try power cycling the modem by unplugging it for 15 seconds and plugging it back in.
Does TDS Telecom require a modem for fiber internet?
No. TDS fiber service uses an Optical Network Terminal (ONT) instead of a traditional modem. The ONT is installed by a TDS technician and serves the same purpose as a modem by converting the fiber signal for your home network. You connect a standard wireless router to the ONT using an Ethernet cable. TDS recommends a Wi-Fi 6 capable router.
How do I activate TDS home phone service?
In cable service areas, TDS phone service requires a TDS-provided multimedia modem with a built-in phone port. You simply connect a phone to the modem's telephone port after completing internet setup. In DSL areas, phone service runs through your existing telephone wiring, and you just need to plug a phone into an active wall jack with a DSL filter attached.
What do I do if my TDS modem has no internet light after activation?
First, verify that all cables are securely connected. Then restart the modem by unplugging power for 15 seconds and plugging it back in. Wait 30 to 60 seconds for it to fully reboot. If the Internet light still does not turn solid green, check whether there is a service outage in your area by visiting the TDS outage map at tdstelecom.com or calling TDS Technical Support at 1-888-225-5837.
Can I set up TDS voicemail during modem activation?
Voicemail setup is separate from modem activation but can be done right after your phone service is working. Pick up your landline phone and follow the voicemail setup prompts, or visit the TDS phone support page at tdstelecom.com/support/phone for step-by-step voicemail configuration instructions specific to your area.
