Slow upload speeds? - Time Warner Internet

This question is about "Slow upload speeds?", with Time Warner Cable internet and apps. Hi,

I have an Arris SB6190, and gigabit Spectrum. Up to 2 days ago, I was getting ~350 down and ~20 up. Both up and down lights on my modem were blue. For the last 2 days, the uplink button is yellow and upload speed is ~6 (yes, a gigabit sub). When I go to, I see that there's only 1 uplink bonded channel.

Any idea what I should do? Tried restarting the modem, reconnecting the cable, no results.

The event log has some errors, but only from yesterday, not today (yet the up light is still yellow). Of course Spectrum says that nothing is wrong.

Slow upload speeds??
