Fiber internet is changing how Miami-Dade County works, learns, and plays. From video calls in Miami Beach to 4K streaming in Kendall, a glass-thin strand of fiber can move data at the speed of light—literally. This guide shows you exactly how to get it, who sells it, and which neighborhoods already glow with gigabit service. Read on, follow the steps, and tap the links to explore every city and provider across Miami.
Why Fiber Internet Matters in Miami-Dade
- Blazing speed: Fiber starts at 300 Mbps and scales to multi-gig plans. That means smoother Zoom calls, lag-free gaming, and instant cloud backups.
- Equal upload + download: Perfect for home businesses, Twitch streams, and large file sharing.
- Weather-proof lines: Buried fiber is sealed from salt air and heavy rain, two big South Florida worries.
- Future-proof tech: Engineers expect today’s fiber strands to last decades without swapping the glass.
Fiber vs. Cable, DSL, and 5G
| Need | Fiber | Cable | DSL | 5G Home |
| Max speed today | 1–5 Gbps | 100 Mbps–1.2 Gbps | 25–100 Mbps | 72–245 Mbps |
| Upload speed | Same as download | 20–35 Mbps typical | 2–10 Mbps | 15–30 Mbps |
| Latency (gaming) | 5–15 ms | 15–35 ms | 25–50 ms | 35–60 ms |
| Data caps | None on top plans | Some | Yes | None / soft |
Fiber wins on speed, uploads, and future growth. Cable is strong runner-up in condos that cannot get fiber yet. 5G is a handy backup if you rent or move often.

Rural edges of the county (Redland, farm zones) may not have fiber yet—check Starlink or T-Mobile Home Internet as gap fillers, then re-check fiber every six months.
Step-by-Step: Find Out If Your Address Has Fiber
- Gather your exact address (street, unit, ZIP).
- Run the address on each major provider’s look-up tool:
- AT&T Fiber availability page
- EarthLink “Show Plans” address checker
- Brightspeed “Check availability” form Brightspeed
- Compare the speed tiers that appear (300 Mbps, 1 Gig, 2 Gig, 5 Gig, etc.).
- Cross-check on InternetInMiami.com. For example, open the Miami Beach page to view every bundle in one list.
- Call or chat for promos. Ask about new-customer pricing, router fees, and install dates.
- Schedule the install. Most fiber jobs wrap up in under two hours when conduit is already on the pole.

Step-by-Step: Switch From Cable to Fiber
- Pick your date—aim for afternoon when you can be home.
- Back up critical files (just in case you lose service for an hour).
- Clear a path from wall jack to your router shelf; tech needs room to work.
- Installer visits: Drills one tiny hole, runs fiber, adds an Optical Network Terminal (ONT).
- Connect router, test Wi-Fi. Ask the tech to run a speed test on both wired and wireless.
- Cancel old service after fiber is live. Return cable equipment to avoid fees.
Max Out Your New Fiber Speed
- Use Wi-Fi 6 or Wi-Fi 6E routers—older 802.11n hardware will choke the gigabit line.
- Place router high and central to cut wall interference.
- Wire key devices (gaming PC, 4K TV) with Cat-6 cables for full gig throughput.
- Check device network cards; many laptops top out at 600 Mbps on Wi-Fi 5.
- Run periodic speed tests and reboot if speeds drop.
The Future of Fiber in Miami-Dade
Quantum Fiber’s XGS-PON upgrade means 10 Gbps lines are possible without digging new trenches. Brightspeed plans to push 2 Gig service into more rural corners near the Everglades by late 2025. County officials are also exploring public-private grants to wire low-income areas, pairing fiber backbones with neighborhood Wi-Fi hubs. Translation: even if your block lacks fiber today, it may arrive sooner than you think.
Frequently Asked Questions
How long does fiber installation take?
Most homes see the tech in and out in about 90 minutes. If the crew must drill a new path through brick or run cable up a long condo stack, plan for up to 3 hours. You can use the time to move furniture and snap photos of where the new wall plate goes—helpful later if you switch providers.
Do I need to buy a modem?
No. Fiber uses an Optical Network Terminal (ONT), which the installer mounts on your wall. Nearly every Miami-Dade provider—AT&T Fiber, Quantum Fiber, Brightspeed—bundles a Wi-Fi 6 gateway with the plan. You only pay extra if you want to add mesh nodes for a larger house.
Will storms knock out fiber?
Unlike old copper, fiber strands carry no electricity, so lightning strikes and power surges can’t travel the line. The main risk during a hurricane is a local power outage. A cheap UPS battery backup keeps your router alive for two to three hours so you can still stream storm updates.
Can renters get fiber?
Yes. Ask your landlord or condo board for written okay. Installers have thin, paint-able wall plates that look like a phone jack. If outside drilling is not allowed, many apartments run fiber through the same ceiling tray as the cable TV line.
Is 300 Mbps fiber enough for a family of four?
For most families, yes. You can stream four 4K movies at once and still leave plenty of bandwidth for homework uploads. If two people work from home on daily video calls, consider a 1-Gig plan for extra headroom.
What if fiber is not at my address?
First, double-check availability on InternetInMiami.com—new streets go live every month. If fiber still says “coming soon,” look at T-Mobile Home Internet, Starlink, or XNET WiFi as gap fillers. Re-run address checks each quarter; AT&T and Brightspeed are actively trenching new lines in South Dade.
Does fiber cost more than cable?
Not anymore. Entry fiber plans in Miami start around $55–$60 per month, the same as Xfinity’s cable promo—yet fiber gives you equal upload speed and no hidden “broadcast fee.” Over a two-year span, lower junk fees often make fiber cheaper.
Can I keep my existing phone number?
Yes. Tell the sales rep you want to port your number to Voice over Fiber. The switch is free, but leave the old phone plugged in until you see the green “Port Complete” text or email from your new provider.
Will fiber speed up my smart home?
Absolutely. Faster uploads and lower latency mean your doorbell camera sends clips to the cloud in seconds, not minutes. Voice assistants—Alexa, Google, Siri—answer quicker because they no longer wait in a long cable queue.
How do I switch providers?
- Pick a fiber plan and schedule the install.
- Test speeds on both Wi-Fi and a wired laptop.
- Then call your old company (Spectrum, Xfinity, etc.) and cancel. Return their router within 10 days to dodge late fees. The overlap ensures you never lose internet for work or school.
Click your city—Doral, Miami Gardens, or any neighborhood—to view plans, or jump straight to your preferred provider’s page, such as AT&T Fiber Miami or EarthLink Fiber. In just a few minutes you can lock in gigabit speeds, future-proof your home network, and enjoy smoother streaming all over Miami-Dade County.
Stay connected, stay fast, and welcome to the fiber future.
