Ever wonder how fast Cox internet can really go? You're not alone. With so many plans out there, it’s easy to get lost in marketing terms. If you’ve been hearing about Cox’s top-tier internet, we’re here to unpack what it actually means—no jargon, no fluff.
This article gives you the real breakdown of Cox’s fastest internet in 2025. From how fast it goes, to what it costs, and even whether it’s worth your money—we’re laying it all out. If you’re thinking about upgrading or just curious what Cox offers at its peak, stick around.
By the end, you’ll know what Gigablast is, what speeds to expect, and if it fits your needs. Let’s get into it.
So, What’s the Fastest Internet Plan from Cox?
Cox’s top plan is called Gigablast. It offers download speeds up to 1 Gbps (1,000 Mbps). That’s more than enough for heavy streaming, gaming, video calls, and running a bunch of devices at once.
Uploads cap around 35 Mbps. It’s not lightning-fast for uploading big files, but most users find it just fine for Zoom, Drive, and everyday tasks.
What is Cox’s fastest internet speed?
Right now, it's 1 Gbps down, 35 Mbps up. That’s their Gigablast plan. It’s perfect for busy homes that never stop streaming or working online.
Quick speed facts:
- Download: Up to 1,000 Mbps
- Upload: Up to 35 Mbps
Wait—Is It Real Fiber?
Kind of. Most Cox users are on what’s called a hybrid fiber-coaxial system. That means your home isn’t directly wired with fiber, but the network uses fiber up to a point, then switches to coax cable. It’s fast, but not “true fiber.”
In a few lucky cities, Cox is rolling out full fiber plans with speeds up to 2 Gbps—both up and down. But that’s still expanding and not everywhere yet.
Does Cox have fiber?
Yes, but in limited spots. Most customers get the hybrid version. Still fast, just not fully fiber to the house (yet).
And the Cost?
Gigablast usually starts around $119.99/month, but prices can vary. New customers often get discounts for the first year. Just watch for changes after the promo ends.
You might also pay extra for their Panoramic WiFi router—about $13/month—and installation fees if you don’t qualify for the DIY kit.
Is it worth it?
If you’ve got a big household, lots of screens, and need speed? Absolutely. But if you’re just checking emails or watching Netflix now and then, you might be fine with something slower (and cheaper).
Good fit for:
- Remote work and video meetings
- Gamers and streamers
- Families with many connected devices
- Uploading videos or big files regularly
The Bottom Line
Cox’s Gigablast plan gives you serious download speed, wide availability, and a reliable connection for high-demand users. It’s not symmetrical like some fiber plans, but it still holds its own for most people.
Want faster? Cox is testing multi-gig fiber in some areas, so you might see 2 Gbps plans in the near future. But for now, if speed is what you need, Gigablast is the best Cox has to offer.
