Bad packet loss for a few months.
Have had intermittent packet loss that is really disruptive for a few months. I have exchanged my old gateway for a new one at xfinity store but it didnt help. Tried different ethernet cable to see if it was my pc but it happens on all devices, wired and wifi. Never had an issue before. Spikes up to 60+ percent packet loss.

Those entries are unhelpful as they are router component errors, not modem component RF errors.
What is the exact make and model number of the modem / gateway device ?
Please also copy all of the text in its entirety of the *Downstream Power Levels*, the *SNR's* (Signal to Noise Ratios), and the *Upstream Power Level* numbers and paste them into your next post.

This may or may not be the root cause of the problem (YMMV) but it should be addressed regardless.
The downstream power is too high. It may be over-driving the front-end receiver circuit of the modem. That can cause random disconnects, spontaneous re-booting of the modem, speed, packet loss, latency problems, and the un-bonding of channels.
Is there a drop amplifier on the coax cable line leading to the modem ? If so, try removing / bypassing it and see. If not, you can try installing a -6 dB forward path-only attenuator pad such as this one on the coax port on the rear of the modem to knock that power level down and see;

It won't affect the upstream power level which is within spec. Good luck !
