PC Looses Network Connection
I have a Dell Precision 3460 PC (Intel 1219-LM, WIN 11Pro) which for about 10 days now seems to loose it LAN connection after 15-30 minutes. I stuck in an ASUS Wireless adapter, which works better, b...
What is the DNS setting in the router configuration? The DNS supplied by your service provider or a public one like Cloudflare, Google, Next, or etc?
Do you have the router DNS configured for and enabled for both IPv4 and IPv6?
I also have seen the reserved IP address both inside and outside the DHCP range. Should be easy enough to test one way or the other to verify if one works and one doesn't. I have found you can reserve an IP address within the router configuration or set a fixed IP address on a device itself. Some people do both and I was never comfortable with that setup. Personal preference was to set a fixed IP address within the device itself. Such as IP cameras, NAS, or wired access points. That way I was certain of the path into the configuration panel of the device.
I'm using Cloudflare and Quad 9
1.1.1.1, 1.0.0.1, 9.9.9.9
In windows when I set up the fixed I on the device (Ipv4 with IPV6 off), it proposes that I use 10.1.10.1 which is the router, which I assume then refers to the above. Windows suggests not to use the above DNS servers. DNR, but a message about conflicts I think.
The ISP (RCN) does not support IPV6 and there are no options in the Advanced => Setup => Internet Setup page. The manual seems to imply it will auto detect this.
The Reserved range is 100-254. I have devices setup inside and outside the range. This is the only one with issues. As it appears that device are working outside the range, I think I will pick a small range that is not used so all the reserved ones are outside it. I can easily live with something small like .20 to .40 which is not in use. There should never be more than a couple of unreserved devices on this LAN.
As noted up top, is that when the PC looses it's connection it seems to have issues related to changing network settings. It seems like the function is locked. It's not behaving like it's just disconnected.
