Coda56 issues

I recently was having slow internet speeds due to having an older modem. I have just upgraded to the Hitron Coda56 about 5 days ago, and since “upgrading” my internet has gotten even slower. I’ve talked to countless agents on the chat with no solution. I just want my internet back up and running. Someone please help.

Greetings @user_jwx5qz, and thank you for posting on our Xfinity Forum! Sorry to hear your speeds got worse after upgrading, that’s definitely not the experience we want for you, especially after already working through this with multiple agents.

Since you’re using your own modem, we recommend double-checking that it’s fully supported for your speed tier and provisioned correctly. You can review the list of approved third-party modems and what speeds they’re compatible with here: https://www.xfinity.com/support/internet/customerowned

If everything looks good there and you’re still seeing slow speeds, let us know!

@XfinityMelinda​ It is definitely on the list. How do I know if it is provisioned correctly? I’m still experiencing slow speeds, to the point where I can’t even use my wifi right now.

I apologize you’re still dealing with this, especially since it’s impacting your ability to even use WiFi. Let’s narrow things down a bit, so we can help more effectively:

- Are you seeing the slow speeds on all devices, or just specific ones?

- Are you testing speeds over WiFi or a hardwired (Ethernet) connection?

- If you connect a device directly to the modem, do you still see the slow speeds?

- Have you tried restarting the modem since the issue started?

You can also troubleshoot your internet speed using our Xfinity App. See details in our helpful article https://www.xfinity.com/support/articles/internet-connectivity-troubleshooting.

If you’re still running into issues after trying those steps, let us know, as we're here and happy to help further.

I’m having slow speeds on all devices. I have only been trying over WiFi, as I have a newer Mac laptop with no Ethernet port. I have reset the modem and the router multiple times.
