Woah, something is drastically wrong there, your Downstream SNR Margin is now at 0.4 dB which is extremely low, I think the Downstream FEC figure has got stuck because of this, I'd do a manual resync immediately.
FEC's aren't an issue especially with Downstream G.INP enabled, but your router is working incredibly hard to keep the line stable and surprised to say the line hasn't lost sync yet.
