So basically talked to isp and they said i should be locked into all 32 channels and hes never seen this happen and told me to come here and ask for any answers?

Those criticals needs to be reviewed by the ISP and resolved. They indicate a signal line issue. Be sure your using a good quality LAN cable between the modem and router. CAT6 is recommended. What is the brand and model of the host wifi router connected to the modem? Have the ISP check the signal and line quality UP to the modem. Be sure the ISP provisions the modem correctly.Be sure there are no coax cable line splitters in the between the modem and ISP service box. Be sure your using good quality RG6 coax cable up to the modem. Start with removing any amplifiers, signal attenuators, or splitters from the coax.From there check the line for kinks, damage, moisture in the line.Check the connectors for improperly made ends, foil touching the copper coax line, loose connections, bad/old/cheap connectors, or corroded connections. Replace them if you do.https://community.netgear.com/t5/Cable-Modems-Routers/General-info-and-Troubleshooting-for-Cable-Modems/m-p/1530376#M12853https://kb.netgear.com/24311/Power-level-guidelines-for-a-NETGEAR-cable-modem-routerhttps://www.duckware.com/tech/solving-intermittent-cable-modem-issues.htmlhttps://highspeed.tips/docsis-events/ Might try a different modem and see. The CM700 is getting up in age and maybe a newer generation maybe needed.

Could try the modem at a different location as well, like at a friend, neighbor or families place to see if problem follows or not.

What model modem is this? What Firmware version is currently loaded?Please post a copy and paste of the modems connection status and event log page.https://kb.netgear.com/30008/How-do-I-view-or-clear-the-event-logs-on-my-NETGEAR-cable-modem-or-modem-router Power levels are a tad bit high: https://kb.netgear.com/24311/Power-level-guidelines-for-a-NETGEAR-cable-modem-router I seem some correctables that should be mostly zeros like the other channels. Then try a factory reset on the modem with the ISP cable line disconnected. Power OFF the modem for 1 minute. Then reconnect the ISP coax line, then power ON. Check channels again.

thanks for help man, and its Firmware VersionV1.02.06 , I'm trying the reset and removing coax now ill brb
