I installed my new gigabit router using the web interface and not the tether app, BTW.  I accepted all defaults and set up just one band.

Since this, the Spectrum streaming TV platform doesn't work.

Spectrum, who i called several times, said nothing in an issue on their side and I have access through any other network, just

not mine at home with this router.

I can stream and access all other apps as usual.  It is just the SpectrumTV app that won't work.

Any thoughts would be appreciated as I would like to use Spectrumtv directly but cannot since I installed my Arher AX10
