How is it that I upgraded to the highest speed, and nothing has changed?

I upgraded to the highest speed, but there was minimal difference. I cannot connect to a call if an other person is even just watching Netflix or is also on a call. How can this be fixed...?

Hi Ieman

Did you try to turn off the modem for 2 minutes if the new billing cycle started?

Did you try with the computer connected with the ethernet cable?

It can also that the signal is weak

Try to disable the band steering this can help

This change can also be applied through the Wi-Fi modem user interface:

1. Log in at: 192.168.0.1 from the web browser of any device.
2. Log in using the following information:
Username: cusadmin
Password: xxxxxxxx (Password you chose during initial setup)
3. Go to the next section to apply changes:

Wireless → General Settings → 5GHz → Band Steering (Disable)

Also try to change channel

A series of channels are available on each frequency (2.4 and 5 GHz) of your Wi-Fi modem. Interference can have an impact on these channels.
Manually changing the channels used for your Wi-Fi connection can improve your modem’s signal.

Wireless → General Settings → 5 GHz → Wireless channel

And also for the 2,4Ghz

Wireless → General Settings → 2.4 GHz → Wireless channel

Changes usually become active with the next billing cycle and are not immediate.

I'm aware, but I upgraded in November.
