Rhino90 Posted August 1, 2018 Share Posted August 1, 2018 I tried to log into the router and noticed it was slow to open the page. I noticed that one CPU usage was pegged at 100%. Not both CPU's, they would alternate to 100% but both still very high. Normally the CPU's utilisation is low. I then checked the logs and it showed a lot of DHCP events happening quite fast. This is not normal. I checked the device MAC addresses and they happen with computers, iPhones, iPads etc, so I don't think it's the clients. Please see attached pictures. When the router gets into this state, I have to reboot it. Link to comment Share on other sites More sharing options...
Administrators Netduma Fraser Posted August 1, 2018 Administrators Share Posted August 1, 2018 I think what is happening is that DHCP Lease is by default set to 24hours. Looks like yours renews at around 10:30pm. You shouldn't need to reboot. When it happens again open a cmd prompt on your PC and type the following: ipconfig /release and press enter ipconfig /renew and press enter once it's done then try and access the interface, does it appear to load fine then?

Rhino90 Posted August 1, 2018 Author Share Posted August 1, 2018 Thanks Fraser. I'll take a note of it and keep a lookout the next time it does a DHCP refresh to all devices. It was just strange that the router became very slow with high CPU utilisation as normally and after a reboot, it's very low at around 25-30%. Very happy with the router otherwise and looking forward to new features. Link to comment Share on other sites More sharing options...

I imagine its just because of the DHCP Lease running out, if its not then we can look into it further Link to comment Share on other sites More sharing options...
Bmann Posted August 1, 2018 Share Posted August 1, 2018 This is what I reported after a few hours of owning my router. My logs always indicated DHCP lease renewals and then my connections would drop. Link to comment Share on other sites More sharing options...

Bmann Posted August 1, 2018 Share Posted August 1, 2018 I never installed the firmware for drops on purpose since I was trying to determine root cause. I was able to get mine stable without using it and am waiting for the new firmware with all those fixes bundled together. I have observed the DHCP and CPU spikes but was just holding out for new firmware. Link to comment Share on other sites More sharing options...
