Hoping y’all can help me cause the internet is not my Forte. I’ve been encountering an issue for about the past 2 years where webpages won’t load without refreshing a couple times and we get a message that the dns is not found. The issue is sporadic but frequent. 90% of the time if refreshing doesn’t work clearing my dns cache does.
The issue occurs on all the computers connected to our network. One is connected via ethernet and the rest via wifi and they all have the issue. We’ve moved in the past year and the issue has persisted after the move. We own the router and modem so those stayed the same before and after the move.
So far I’ve tried the following troubleshooting but nothing has worked: -Restart the modem and router -factory reset the router -remove the Raspberry pi running pihole (issue was present before this was set up)
If you are using an isp router it is assigning a dns server to devices via DHCP. If you go into the router, you’ll likely be able to modify DHCP settings. I would set the DNS server to be either cloudflare (1.1.1.1) or google (8.8.8.8).
If you want to test that this will fix the issue, you could manually set one of your devices to use 1.1.1.1 for DNS and see if it resolves the issue.
If your router doesn’t allow you to modify these settings, you could turn DHCP off on the ISP device and then have another device on your network act as the DHCP server. Many consumer routers/WAPs have optional DHCP servers that can be enabled.
Building off of this, make sure your modem is bridged and the router is handling all of traffic
Set your ISP (WAN) to DHCP for IP address but the ISP DNS to manual and set it to 8.8.8.8 and 8.8.4.4
Your internal LAN DHCP should be set to auto.
Make sure you enable uPNP and you turn off Advance Firewall Services like SIP ALG or other garbage like that. Other garbage may include stateful packet inspection.
What kind of modem and router you have?
