Re: DHCP Renewing issues

Are you experiencing any issues such as disconnections that accompany these entries in the log?

Re: DHCP Renewing issues

Re: DHCP Renewing issues

So the disconnects are happening every hour? Is it only on certain devices or all devices? Wired or wireless?

Re: DHCP Renewing issues

It varies, I only notice it when I see printer go offline and display lights up. Its on all devices and I've notice ARP issues too. Below is current log:

Re: DHCP Renewing issues

Could you give the known affected devices and the others reserved IP addresses in LAN settings please and see if that stops the disconnects?

Re: DHCP Renewing issues

I can try or I was going to factory reset and see what happens. I did read something about if you moved the device from one area ISP to another that a factory rest may help and let it reconfigure as a new setup in the new ISP area. I believe that might be the quicker route. If it still happens, Then I'll go for Static IP's. ONly 2 items are hardwired, CPU and Printer. I did notice when I was trying to add printer as a wireless or hardwire, both XR500 would see it an well as Windows 10 however it wouldn't print, jobs would be stuck in que, so I just add a TCP port for printer with and IP and it printers and scans fine.

Re: DHCP Renewing issues

Sounds good, try the reset and IPs after if it's still a problem and let us know how you get on.

Re: DHCP Renewing issues

Ok Hard reset is done, only thing I changed during setup was naming the ISP WLAN name. I can now print and scan through direct wire which is a plus. I'll repost later on to see if I get renewing issues again. I did look at the connection stauts page and see the following:

Lease Obtained = 0 Days, 16 Hours, 34 Minutes

Lease Expires = 0 Days, 15 Hours, 56 Minutes

Thats base off IPS' IP Address NOT the Routers DHCP

Re: DHCP Renewing issues

It's been a full day and NO Resets. I did a hard reset on the router not in the routers OS. Did the basic unplug and plugin one at a time and all is good. I did go through all the settings to see if I would notice any setting changes and one thing that did stand out was for some reason the Disable Port Scan and DoS Protection in WAN Setup was checked and in the ipv6 was set at Auto now at disable. So with those 2 things different and off all is stable and I can now print, Raid WoW, and stay connected. Thank you for your help and let all remember ... when in doubt just unplug it, reset it and start from scratch.
