Speed down to 90 Mbps

Hello,

After restart my speeds are over 550Mbps but within an hour they will go back down to 90Mbps. They will stay there forever unless the modem is restarted.

I have tested via Ethernet directly to modem and results are the same. I have removed all splitters inside and outside the house and installed a 6dB attenuator.

The issue has been going on for months now. Modem is Arris SB8200. Channel info is below, please help!

Good evening @user_99mdz3, and thank you for reaching out on our Community Forums with your speed issues. We're sorry to hear that you are experiencing issues with your connection and you need to restart your modem in order to get your speeds back up, I can imagine how frustrating this must be getting for you and you shouldn't have to restart your modem that frequently. I'm also sorry to hear this has been going on for months but want to assure you that our team will do everything we can to get this resolved, you're in good hands! May I ask if you experience slow speeds across all of your devices or is it one in particular such as a specific computer or Smart TV? May I also ask how old your modem is?

Hello, thank you for the reply. Speeds are as tested by my router, and confirmed by connecting a computer directly to the modem. Hard to say how old the modem is, I would think a few years. It's hardware version 4, if that tells you anything.

Same issue here. I’ve connected with both wifi and a cat 6. Neither go above 90 mbps download. XFSetup-8BXF router. This looks like the “ole switcheroo.”
