I see those DNS IP addresses Spectrum(TWC) uses. Your CMD results should display the public server addresses. It looks like DHCP has configured your DNS to act as the Default Gateway for both IPv4 and IPv6. This setup doesn’t make much sense to me. Why do clients send DNS requests to the router’s IP and then let it assign the real DNS address? Instead, clients should simply attach the DNS IP and forward it directly. Remove the intermediary step. Once you select your DNS servers, restart your computer or run the commands “ipconfig /release” followed by “ipconfig /renew”. This will clear the old settings and ask the router for fresh IP and DNS information. After that, check “ipconfig /all” to confirm the servers are listed correctly.
Well, it appears to be okay. It just looks like an extra step that isn't needed. Check if this affects anything. If the lag spikes persist, we can set up static DNS servers on your computer. This should prevent your router from handling DNS requests and might reduce latency slightly.
Your device is communicating with your router, which then sends the data to the DNS server mentioned. It’s possible your router supports several DNS configurations. You can configure it via DHCP and WAN settings, as you do. Generally, DHCP provides direct IP addresses, while the WAN section sets the router’s DNS when it receives a request. Since these are just your own DNS servers, it’s acceptable if others use different ones. Your setup is a bit complex because you also run a personal DNS server on a Raspberry Pi.
It seems there could be a problem with the cable for your TV or possibly a loose connection. Second, I need to confirm the type of service you're using. You mentioned fiber, but I want to clarify since fiber cables aren't shared between ISPs—it can't be the same. The issue you're describing likely relates to DSL. Third, those spikes are probably from wireless interference or line saturation and EMI. More details would help resolve this. Adjusting your DNS server won't fix it.
I'm still experiencing some lag, though it really improved once it started. When it does lag, I rarely notice it because I don't have time. I might need to assign a static IP to help with the printer issues. Someone else reported a similar problem with the Brother DCW-L2540 and fixed it by changing the printer settings to static IP. My printer was already set that way, but sometimes it stops working after a while if not used. There seems to be no impact on VPN performance.
As discussed before, the ISP is Spectrum. We’re using fiber internet with a coaxial modem, not DSL. The problem appears on both WiFi and Ethernet connections. Switching DNS helped significantly, but I’m still experiencing some minor delays instead of the major outages I faced earlier. It’s unclear what else to try besides setting a static IP, as suggested in Windows 7.
Ensure it’s positioned high enough in the pool to avoid interfering with other devices’ IPs. It seems there could be an IP conflict, possibly involving printers or other equipment. Just confirm the placement is higher on the network side. The static IP for the printer and VPN are unrelated.
These are two distinct technologies. If it's a coax modem, you have cable, not fiber. The first option won't work unless you contact Spectrum and pay for a service or set up a static on your PC. That’s not a helpful response to this issue. The second is about wired connections using cable, similar to how DSL operates. Although I’m familiar with DSL and fiber, I have some knowledge of cable and it might be a poor line. If you could log in to your modem and share some stats, I’d be able to provide more insight.
I'm not part of the ISP team, but I'm a Comcast customer and their support isn't very helpful. I've picked up some basics about how it all functions. As mentioned earlier, we should refer to the stats from the signals page and the logs on the modem. Usually, you can connect by visiting 192.168.100.1. Not every ISP lets you in, but some do. If the modem isn't working properly, it might lead to slow speeds or drops. Poor signal strength is something we can check first—either see if your connection is weak inside your home (your job) or if the problem lies outside (ISP's responsibility). It could be a faulty line at your house, a bad connection on the ISP's side, or even wiring issues with neighbors. To clarify, companies like Cable Co (Spectrum) aren't fiber providers; they only offer fiber to specific locations for a very high cost. They supply fiber at the node level, but the actual service inside your home depends on how much bandwidth is assigned there, which varies by area. This might cause problems if you're on a heavily used node.
