1Gbps Upgrade Causing Weak & Unstable Wi-Fi on Multiple Devices

I recently upgraded my Xfinity internet to 1Gbps, and since then, I’ve been experiencing constant connectivity issues with some of my devices—issues I never had before.

Devices Affected:

  • Apple Devices (iPhone, iMac, iPad) → Frequently disconnecting or showing weak/fair Wi-Fi signal.
  • Android TV Box → Also had similar issues at times.

Troubleshooting Done:

  1. Xfinity App "Test Your Whole Home Network" Results:
    • iPhone → Weak Wi-Fi
    • iMac → Fair Wi-Fi
    • iPad → Weak Wi-Fi

  2. Technician Visit (1 week after install):
    • Mentioned something about loose cables and an old DirecTV cable possibly causing interference.
    • Issues persist despite this check-up.

  3. Wi-Fi Reset & Router Placement:
    • Reset the router multiple times.
    • No significant changes in device locations.
    • Never had this issue before the upgrade.

At this point, I don’t know if this is a hardware issue with the gateway, a Wi-Fi interference problem, or something else. The fact that Apple devices consistently show weaker Wi-Fi signals makes me wonder if it’s a compatibility issue.

Has anyone else experienced Wi-Fi stability issues after upgrading to 1Gbps?

Thanks

mingogomes Thanks for posting on our Forums. What speed tier did you have before the Gigabit upgrade? Did the technician advise if the old lines could be removed or if additional work would be referred to a maintenance team? Are all devices connected through WiFi or do you have any that are hardwired with an ethernet cable?

Hey!

Thanks for reaching out.

Both technicians advised me not to separate the networks (2.4, 5, and 6 GHz), saying the router could handle it automatically.

I’m not sure why I trusted them—I've separated them in the past without any issues. As soon as I did it again, all the problems with Apple products disappeared.

So, yeah, the issue wasn’t with the installation but with the settings.

Hopefully, this helps others facing the same problem.

Have a great day!

I appreciate the follow-up and for letting us know what corrected the issue. That does sound strange for sure, but I'm glad that it works!

Thank you for reaching out and sharing your experience with us. We understand how frustrating it can be when your Mac frequently says it can't show the page and your phone has to redial due to no Wi-Fi.

Here are a few steps you can try to improve your connection:

Restart Your Devices: Sometimes, simply restarting your Mac, phone, and router can resolve connectivity issues.
Check Your Wi-Fi Signal: Ensure that your devices are within range of your Wi-Fi router. If the signal is weak, try moving closer to the router or consider using a Wi-Fi extender.
Update Software: Make sure that your Mac and phone are running the latest software updates. Outdated software can sometimes cause connectivity issues.
Reset Network Settings: On your phone, you can reset the network settings to refresh the connection. Go to Settings > General > Reset > Reset Network Settings.
Check for Interference: Other electronic devices or thick walls can interfere with your Wi-Fi signal. Try to minimize interference by placing your router in a central, open location.

On your apple devices, disable the random MAC address 'feature'.  It does not increase security, and can cause the problems you are experiencing.  I would also recommend not separating the channels if you have a modem provided by xfinity.  Their firmware is coded such that separating the channels causes more problems that it 'fixes'.  Also make sure your apple devices are connecting to the 5GHz band, and not the 6.  Apple devices do not play well with wireelss 6GHx signal.  Even the latest OS update has that issue as well. 

If you absolutely must separate channels, it would be better to get an approved third party modem that is compatible with your speed tier.
