TDS Telecom Speed Test

TDS Telecom is a name you rarely hear in conversations about major internet providers, but that is kind of the point. This Madison, Wisconsin-based company has quietly served small towns and semi-rural communities across 31 states for decades — first with copper phone lines, then DSL, and now increasingly with fiber optics that rival anything Google Fiber or AT&T offers.

If you are a TDS subscriber, your speed test experience will differ wildly depending on which generation of TDS infrastructure serves your home. A customer on TDS's newest fiber network in a Coeur d'Alene neighborhood is living in a very different internet reality than someone on aging DSL lines in rural Tennessee.

Where You Stand: Fiber, DSL, or Somewhere in Between

TDS delivers internet through three distinct technologies, and knowing which one you have is essential for understanding your speed test results:

TDS Fiber (1 Gig / 2 Gig / 8 Gig): This is TDS at its best. Fiber plans deliver symmetrical speeds, meaning your upload matches your download. A 1 Gig plan should show roughly 940 Mbps in both directions on a wired test. The 8 Gig plan is one of the fastest residential offerings in the country, but testing it requires a PC with a 10GbE network adapter and Cat6A cabling — standard Gigabit Ethernet hardware physically caps at 940 Mbps.

TDS VDSL/Bonded DSL: In areas where fiber has not yet arrived, TDS offers DSL over existing copper phone lines. Speeds range from 5 Mbps to 100 Mbps depending on how close your home is to the nearest DSLAM (the neighborhood distribution box). If you are more than two miles from the DSLAM, expect the lower end of that range. Distance is the defining factor for DSL — no amount of router tweaking can overcome the physics of copper wire attenuation.

TDS Cable (select markets): In a few areas acquired from other companies, TDS operates cable internet using DOCSIS technology. These plans behave more like Spectrum or Xfinity — fast downloads but much slower uploads.

The Eero Partnership — What It Means for Your Wi-Fi

One thing that sets TDS apart from many regional providers is their partnership with Amazon's Eero. For fiber customers, TDS typically installs an Eero mesh system instead of a traditional router. This has both advantages and quirks.

On the upside, Eero's mesh technology provides solid whole-home coverage, and firmware updates happen automatically in the background. TDS support can also remotely diagnose Wi-Fi issues through the Eero cloud platform, which speeds up troubleshooting.

The downside? There is no web-based admin panel. You cannot type an IP address into a browser to manage your network like you would with a traditional router. Everything — changing your Wi-Fi password, setting up a guest network, pausing internet for specific devices — happens through the Eero mobile app (iOS and Android). If you prefer a web interface, this can feel limiting.

For advanced users who want more control (port forwarding, custom DNS, VLAN tagging), the best path is to request that TDS configure the ONT in pass-through mode so you can connect your own router directly. Call 1-888-225-5837 to discuss this option.

Older Equipment: The Actiontec T3200M

If you are on TDS DSL or were an early fiber customer before the Eero partnership, you likely have an Actiontec T3200M gateway. This all-in-one device handles both the modem and router functions. Here is how to access it:

Pay attention to the front panel lights on the Actiontec. Solid green on Power, Broadband, and Internet means everything is connected. If the Broadband light blinks green, the modem is searching for a DSL signal — check the phone cable from the wall. If the Internet light turns red, the modem has a physical connection but cannot authenticate with TDS's network — a reboot usually resolves this.

The 100 Mbps Ceiling Problem

This is by far the most common complaint from TDS Fiber customers: "I pay for Gigabit but my speed test shows 94 Mbps." In nearly every case, the culprit is the Ethernet cable.

Old Cat5 cables — the kind bundled with electronics a decade ago — support a maximum of 100 Mbps. This applies to the cable between your computer and the router, and also any cable between the ONT and the Eero. One Cat5 link anywhere in the chain bottlenecks the entire connection.

The fix is simple: replace every Ethernet cable in the path with Cat5e or Cat6. While you are at it, verify that your computer's network port supports Gigabit Ethernet. You can check this in Windows by going to Network Connections → right-click your Ethernet adapter → Status. If it says "Speed: 100 Mbps," either the cable or the port is the bottleneck.

No Data Caps — A Refreshing Change

In a landscape where Xfinity imposes a 1.2 TB monthly cap and Cox enforces 1.25 TB, TDS stands out by offering genuinely unlimited data across all residential plans — fiber and DSL alike. There are no overage fees, no throttling after hitting a threshold, and no "fair usage" policies buried in the terms of service. For households with multiple gamers, streamers, and remote workers, this is a significant advantage.

Practical Questions TDS Customers Ask

Can I get the 8 Gig plan in my area?

TDS's 8 Gig tier is available only in fiber markets and requires an XGS-PON connection. Not all fiber areas have been upgraded to support it yet. The best way to check is to enter your address on the TDS website or call 1-888-225-5837. Even if 8 Gig is available, keep in mind that testing those speeds requires specialized hardware — a 10 Gbps network card, Cat6A cabling, and a compatible router.

Why do my speeds drop during rain?

If you are on DSL, this is a well-known vulnerability. Water infiltrating old copper splice points and junction boxes degrades the electrical signal. It is especially common in areas where the copper plant is aging. Report this to TDS — they can dispatch a technician to seal or replace corroded splices. Fiber customers should not experience weather-related slowdowns.

Is TDS better than Starlink for rural areas?

If TDS Fiber is available at your address, it is objectively the better choice — lower latency (5-15ms vs. 25-60ms), higher speeds, symmetrical uploads, and no weather dependency. If only TDS DSL is available, the comparison gets tighter. A DSL connection offering 15 Mbps may be outperformed by Starlink's 50-200 Mbps — but Starlink costs significantly more per month.

How do I switch from the Eero system to my own router?

You will need TDS to configure your ONT (Optical Network Terminal) for direct pass-through. Once that is done, connect your own router's WAN port to the ONT's Ethernet port with a Cat6 cable. Your router should pick up an IP address automatically via DHCP. Call TDS at 1-888-225-5837 and ask for "ONT pass-through mode" — most agents know what this means.

What is the TDS support number?

For technical support, billing, or plan changes: 1-888-225-5837. You can also manage your account and check for outages through the myTDS app available on iOS and Android.
