Nighthawk AX4: DHCP Not Working - IP not assigned automatically
So, I have had this router for a few months now and I have had issues with wifi on numerous ocassions. At random, the router will begin to not distribute and assign ipv4 ip address for devices connec...
I’ve gone into LAN and reserved loads of devices that never leave the house with fixed IPs, not had any issues for a few months (probably just jinxed myself posting this)
I have a 2.5yo R6350 (AC1750) running the latest firmware: V1.1.0.84_1.0.1 with the same issues. I've tried everything as noted in the first post (and downgrading to 64_1.0.1 or 78_1.0.1 didn't help). What I *did* notice, and this is a poor workaround, is that when I reduced the number of connected devices to < 32, then DHCP began working again.
In all cases, the logfile shows that the IP addresses *are* being allocated, but they never transmitted to the device. With Access Control turned on, successful connections are properly logged when things are working fine. When broken, there are no [Access Control] entries. Again, turning off Access Control does *not* resolve the issue. I believe Access Control is *not* the issue, and the root cause maybe due to an internal table overflow.
The reason that firmware changes or rebooting can temporarily fix is that you reduce the number of devices at bootup. If you have > 32 devices at bootup then it will still fail. A quick test is to change your SSID and try connecting to that one. Things will work until you, once again, connect to too many devices.
My resolution plan is to purchase a new router, but given this major core issue that is not being addressed by Netgear (a wireless router's core function is to connect to wireless devices), I plan to return to Linksys.
Good luck.
Netgear has set up a community forum specifically for Smart WiFi Router products. Most of the people who watch that forum are more likely to have experience with General and Smart Wifi (WN and R6000 thru R6400 Series) routers. Might be more likely to find someone who has a solution if the question is posted there since the R6000 series differs from the RAX router series:
