Fiber Internet Installation — What to Expect in Texas (2026)

**Scheduling tips:** Most Texas providers offer morning (8 AM–12 PM) and afternoon (12–5 PM) windows. AT&T and Frontier allow you to track your tech's arrival in real time via their apps. Google Fiber typically gives a tighter 2-hour window. If your installation requires a permit for underground boring (common in neighborhoods without existing conduit), the timeline can extend to 2-4 weeks.

**How to prepare your home:**

- Decide where you want the ONT (Optical Network Terminal) box placed. The ONT is a small white box roughly the size of a paperback book that converts the fiber-optic signal into Ethernet. Common locations: garage wall, utility closet, or an interior wall near your router's intended location.

- Clear a path from the exterior of your home to the ONT location. The tech will run a fiber cable from the outside terminal to the ONT — move furniture and stored items away from the wall.

- If you live in an apartment or HOA community, confirm with management that exterior work (small drilling, cable routing) is permitted. Most Texas HOAs cannot legally block fiber installation, but advance notice avoids day-of friction.

- Have your Wi-Fi router ready. AT&T includes a BGW320 gateway, Frontier provides an Eero 6 or Eero Pro 6E, and Google Fiber includes their own mesh router. If you plan to use your own router, have it on hand so the tech can verify your connection works before leaving.

**Step 1: Locate the fiber terminal.** The tech identifies the nearest fiber distribution point — a small gray or green box on a utility pole, pedestal at the curb, or inside your apartment building's telecom closet. In newer Texas subdivisions (Sienna Plantation, Harvest Green, Bridgeland), fiber conduit is often pre-run to a junction box on the side of the house during construction.

**Step 2: Run fiber cable to your home.** If conduit already exists, the tech pulls a thin fiber-optic cable through it — this takes 15 to 30 minutes with no drilling. If there is no existing conduit, the tech either (a) runs an aerial drop from a nearby pole to your house and anchors it with a cable clip, or (b) trenches or bores a small underground path from the curb to your exterior wall. Underground work may require a second visit if a boring crew is needed.

**Step 3: Drill and mount the ONT.** The tech drills a small hole (roughly 3/8 inch) through the exterior wall to route the fiber cable inside. The ONT box is then mounted on the wall near a power outlet — it requires continuous power. The tech splices or connectorizes the fiber strand into the ONT. This is the most precise part of the job, and a good tech will test the optical power level at this point.

**Step 4: Connect and test.** The tech connects the ONT to your router via Ethernet, powers everything on, and runs a speed test to confirm you are getting the advertised bandwidth. They will verify both download and upload speeds. If using the provider's gateway (AT&T BGW320, Frontier Eero), they will configure your Wi-Fi network name and password.

**What to watch for:** Ask the tech to show you the speed test results. Confirm the ONT is mounted securely and the fiber cable has a gentle bend radius — fiber optic cable can break if bent sharply. Note the ONT's model number and serial for your records.

**Run your own speed tests.** Use speedtest.net or fast.com on a device connected via Ethernet directly to the router. This eliminates Wi-Fi variables and gives you a true baseline. On a 1 Gbps fiber plan, you should see 900-950 Mbps down and 900-950 Mbps up over Ethernet. Save a screenshot — you will want this if you ever need to troubleshoot a speed drop later.

**Optimize Wi-Fi placement.** The provider's router or mesh system should be placed centrally in your home, elevated (on a shelf, not on the floor), and away from metal objects, microwaves, and thick walls. If your Texas home has a brick exterior or metal studs (common in newer construction), Wi-Fi signals attenuate faster — consider adding a mesh satellite in distant rooms.

**Set up a guest network.** Most fiber gateways support a separate guest SSID. Use it for visitors and IoT devices (smart plugs, cameras, thermostats) to keep your primary network less congested and more secure.

**Register your account.** Create your online account with the provider (myAT&T app, Frontier app, Google Fiber app). Enable auto-pay — AT&T Fiber discounts $5/month with auto-pay and paperless billing. Set up outage notifications so you are alerted if the network goes down in your area.

**Keep the ONT accessible.** Do not bury the ONT behind furniture or inside a sealed cabinet. It needs ventilation (it generates mild heat), and you may need to power-cycle it during troubleshooting. The ONT has a battery backup port on some models — AT&T's BGW320 has an optional battery unit for maintaining phone service during power outages.

**Slow Wi-Fi but fast wired speeds.** This is the most common complaint and is almost never a fiber problem. It means your Wi-Fi router is the bottleneck. Solutions: move the router to a central location, switch to the 5 GHz or 6 GHz band (Wi-Fi 6E routers), upgrade to a mesh system, or connect bandwidth-heavy devices via Ethernet.

**Intermittent disconnections.** If the ONT's optical light blinks red or goes off, the fiber strand may have a bad splice or a micro-bend in the cable run. Contact your provider and request a technician — this is a physical layer issue that cannot be fixed remotely. If the ONT light is solid green but the router drops, reboot the router first. If the issue persists, factory-reset the router and reconfigure.

**Speeds lower than advertised on wired test.** Confirm you are using a Cat5e or Cat6 Ethernet cable (Cat5 caps at 100 Mbps). Confirm your computer's Ethernet port supports gigabit — older laptops may have 100 Mbps ports. Test on a second device to rule out a NIC issue. If wired speeds are still 50% or more below your plan, call the provider — the ONT may need re-provisioning or there may be a fiber integrity issue.

**Provider app shows different speed than Speedtest.** Provider speed-test tools often measure to a nearby server they control, which can show inflated results. Use a third-party test (speedtest.net, fast.com, or Waveform speed test) for an unbiased measurement. Test at different times of day — fiber is less susceptible to peak-hour drops than cable, but your router or home network can still introduce variability.

**ONT making noise or running hot.** ONTs are passively cooled and should be silent. A faint warmth is normal. If the unit is uncomfortably hot to touch or making audible noise, it may be defective — request a replacement from the provider. Do not place the ONT in direct sunlight or inside an enclosed, unventilated space.
