Re: CAX30 AX2700 - DHCP not working properly after power outage
Having the exact same problem. This has actually happened twice to me so far. The last time being last night after a power outage. I have reached out to tech support from both sides (netgear and ISP (...

As stated in my reply post ISP is Comcast. Firmware is V1.4.10.8. I’ve contacted ISP and they've checked the signal as good. I’ve asked them also to provision the modem correctly. The feedback I get from them is that they don’t have the router/modem schematic so they can’t provide support. There is a small cable piece between the coax coming in and the modem/router that they call a splitter but that’s the first time I’ve heard that these are not allowed. Comcast says it’s a necessary device for them.
As far as setting the channels, I haven’t customized any of the settings on the device. It connected fine when it was first installed by the Comcast tech. Worked great. This is the first time that I’ve dealt with a modem/router that failed to come back online and connect all it’s subordinate devices. Don’t know at this point if it’s the device (hardware/software) that’s not truly compatible with it or if Comcast is making it more difficult for outside devices to work with they’re internet. Unfortunately, I think I may have to succumb and get Comcast’s fully supported hardware to avoid dealing with this mess every time this nighthawk needs to be rebooted.

What channels are you using? Auto? Try Auto and 48 on 5Ghz. Or try setting manual channel 1, 6 or 11 on 2.4Ghz and 40 to 48 channel on 5Ghz.
Any Wifi Neighbors near by? If so, how many?
Please post a copy and paste of the modems connection status page.
Also try a factory reset and setup from scratch.
Go in and save off a backup configuration to file for safe keeping:
After the back up is saved, unplug the power adapter from the wall out let for 30 seconds then back in. Let us know what your experiences are after the modem comes back to ready.
