If you have Astound Broadband cable Internet and want to take advantage of its faster download and upload speeds, the Hitron CODA57 is a DOCSIS 3.1 mid-high split cable modem designed to support Astound’s upgraded cable network.
The CODA57 supports mid-split and high-split upstream frequencies, speeds up to 2.5 Gbps and 2.5 Gigabit Ethernet. These capabilities matter because a standard DOCSIS 3.1 modem may support fast downloads but may not support the expanded upstream frequencies needed for faster upload speeds. The CODA57 is certified for use on Astound’s network.
If Astound offers enhanced upload speeds at your address, choosing a compatible mid/high-split modem helps ensure your modem can support the faster speeds available with your plan.
Always confirm that the modem is supported for your specific Astound address and Internet speed tier before purchasing because Astound’s network and equipment requirements vary by service area.
Why Do Faster Astound Speeds Require the Right Modem?
Faster Astound cable Internet can require more than a standard DOCSIS 3.1 modem. If your Astound service uses expanded upstream spectrum to provide faster upload speeds, your modem must also support that upstream network configuration.
Astound currently offers Internet speeds as high as 5 Gig download and 1 Gig upload in some areas. Astound also states that customers need equipment capable of supporting the speeds provided by their service.
This creates an important distinction when buying your own modem:
DOCSIS 3.1 tells you the DOCSIS generation. It does not, by itself, tell you how much upstream spectrum the modem can support.
A DOCSIS 3.1 modem can therefore support fast downloads while still being limited by its upstream capabilities.
For Astound customers who want faster uploads, that distinction matters.
What Is a Mid-High Split Cable Modem?
A mid-high split cable modem, such as Hitron’s CODA57, supports the expanded upstream frequencies used by Astounds’ newer cable networks to provide more upload capacity.
Traditional cable networks dedicate a relatively small portion of the available coax spectrum to upstream traffic.
A mid-split expands the upstream frequency range.
A high-split expands it further.
That additional spectrum gives the cable operator more capacity for data traveling from your home back to the Internet.
This increased upstream capacity can support faster uploads for activities such as:
- Video conferencing
- Cloud backups
- Uploading large files
- Livestreaming
- Uploading photos and videos
- Cloud synchronization
- Content creation
- Cloud-connected security cameras
However, upgrading the cable network is only one part of the equation.
The cable modem also needs to support the expanded upstream frequencies being used by the provider.
Is Any DOCSIS 3.1 Modem Good Enough for Astound?
No. DOCSIS 3.1 tells you the generation of cable technology a modem supports, but it does not tell you whether that modem supports the expanded upstream frequencies needed for Astound’s faster upload speeds.
If Astound has upgraded the cable network at your address for faster uploads, you need a DOCSIS 3.1 modem that also supports the appropriate mid-split or high-split upstream frequencies.
When choosing a modem for Astound, check:
- DOCSIS 3.1 support for current high-speed cable Internet
- Mid/high-split support for Astound’s expanded upstream network
- Upstream frequency range to confirm the modem can support the upgraded network
- Ethernet port speed to avoid creating another bottleneck between your modem and router
- Astound compatibility for your service address and speed tier
The Hitron CODA57 combines DOCSIS 3.1 with mid- and high-split support, upstream bandwidth up to 204 MHz and a 2.5GbE Ethernet port. These capabilities make it suitable for compatible Astound services that use the upgraded network to provide faster upload speeds.
The key takeaway: Don’t look for just a DOCSIS 3.1 modem for faster Astound service. Look for a DOCSIS 3.1 modem with the upstream capabilities your Astound service requires.
💡 Tip: If faster uploads are important to you, check both the modem’s DOCSIS version and its upstream frequency support before you buy.
What Is the Hitron CODA57?
The Hitron CODA57 is a DOCSIS 3.1 mid/high-split cable modem certified for Astound and designed for cable networks transitioning to higher upstream bandwidth.

CODA57 Feature
Why It Matters
Hitron designed the CODA57 with mid- and high-split support and upstream bandwidth up to 204 MHz, specifically for cable operators moving toward higher upstream capacity.
Why Is the CODA57 a Good Fit for Astound?
The CODA57 is a good fit for compatible Astound cable Internet service because it combines DOCSIS 3.1, expanded upstream support and a 2.5GbE Ethernet port in a modem certified for Astound’s network.
Each capability solves a different potential bottleneck.
DOCSIS 3.1 supports current high-speed cable Internet technology.
Mid/high-split support gives the modem the upstream capability needed for newer cable network configurations.
Upstream support to 204 MHz provides substantially more frequency range for upstream communication than traditional cable configurations.
2.5 Gigabit Ethernet provides more than a 1 Gigabit connection between the modem and compatible networking equipment.
Together, these features make the CODA57 more than simply another DOCSIS 3.1 modem.
It was built for the changing requirements of cable networks where upload capability is becoming as important as download capability.
Does Astound Require a Mid-High Split Modem for Faster Upload Speeds?
If Astound offers faster upload speeds over its upgraded cable network at your address, you need a modem that supports the upstream technology required for those speeds.
A mid/high-split cable modem supports the expanded upstream frequencies that allow cable networks to provide more upload capacity.
The Hitron CODA57 is a DOCSIS 3.1 mid/high-split cable modem designed to support Astound’s upgraded network and faster upload speeds where available.
The key is to match your modem to your Astound service. Your modem needs to support both the download and upload capabilities available with your plan.
💡 Tip: Before buying a modem, check the download and upload speeds Astound offers at your address and confirm the modem is compatible with your service.
Will the CODA57 Automatically Give Me Faster Astound Upload Speeds?
It depends. Two things need to be true for you to get Astound’s faster upload speeds:
- Astound must offer the faster upload speed at your address. Your Internet plan and local Astound network determine the upload speed available to you.
- Your cable modem must support Astound’s upgraded network. Faster upload tiers on an upgraded cable network require a modem capable of supporting the expanded upstream frequencies.
The Hitron CODA57 is a DOCSIS 3.1 mid/high-split cable modem designed to support Astound’s upgraded network. It supports mid- and high-split operation with upstream bandwidth up to 204 MHz.
This means that if Astound offers a faster upload tier at your address, the CODA57 has the modem technology needed to support that upgraded network.
However, the modem itself does not determine the speed Astound provides. If faster upload speeds are not available with your Astound plan or at your address, installing the CODA57 will not increase your upload speed.
Simply put: Astound provides the faster upload speed. The CODA57 provides the modem technology needed to support it.
💡 Tip: Check the download and upload speeds available for your address with Astound before purchasing a new modem.
Does the CODA57 Have a 2.5GbE Ethernet Port?
Yes. The CODA57 has a 2.5 Gigabit Ethernet port so the connection between the modem and compatible router is not limited to 1 Gigabit Ethernet.
Astound specifically recommends a DOCSIS 3.1 modem with a 2.5GE port for speeds above 1,000 Mbps.
Your Internet connection follows a path:
Astound Network → Coax → CODA57 → Ethernet → Router → Your Devices
Each part of that path needs enough capacity to carry the speed you are trying to use.
Connecting a multi-Gig modem to a router with only a 1GbE WAN port can create another bottleneck.
💡 Tip: If you have an Astound plan above 1 Gigabit, check that your router also has a 2.5GbE or faster WAN port.
Does the CODA57 Have WiFi?
No. The Hitron CODA57 is a cable modem, not a WiFi router.
You connect the CODA57 to your own router or mesh WiFi system.
A typical setup looks like this:
Astound coax connection
↓
Hitron CODA57
↓
2.5GbE Ethernet
↓
WiFi Router or Mesh System
↓
Your Wired and Wireless Devices
Using a separate modem and router also allows you to choose the WiFi equipment that best fits your home and upgrade your router separately in the future.
Can I Buy My Own Modem for Astound?
Yes. Astound allows customers in many cable Internet service areas to use their own compatible modem.
Your modem must be compatible with the Astound service and speeds available at your address. Once connected, Astound will need the modem’s MAC address to activate it on your account.
