brand new modem, ISP service connected to RAX80 router. SImple setup, no linke agg (just bouth the ability for the future). ISP service (400gbs up, 40gps down optimum) is good 80% of the time, but randomly drops during the day to bad levels (almost zero or zero up and down). Have had multiple visits from techs and in each case they blamed on outside lines and made adjustments. ISP is suggesting that cm1200 is bad and is recommending replacement with their modem. Modem firmware is 1.01.02, online netgear support shows 1.02.xx available but I can't get the ISP to push the firmware to see if it helps. Full logs in attachment.
