I'm experiencing intermittent issues where websites don't resolve correctly, or I get 'Page Not Found' errors even though the site is up. I've tried changing my DNS servers, but the problem persists.

10 个解决方案Check DNS Server Configuration
Verify the DNS server settings on your router and individual devices.
Test DNS Resolution
From a connected device (if possible), try pinging an IP address directly (e.g., ping 8.8.8.8) and then a domain name (e.g., ping google.com).
Inspect UPS Status
Check the status lights and battery levels of all UPS units powering network equipment.
Check Building Power
Verify if the entire building or office area has power.
Reboot Core Equipment
Attempt a controlled reboot of the primary network devices, starting with the modem/router.
Inspect Core Equipment
Visually inspect the main router, switch, and firewall for any signs of power loss or error indicators.
Check ISP Status Page
Visit the ISP's website or social media for official status updates.
Contact ISP
Call your internet service provider to inquire about any reported outages in your area.
Replace Aging Hardware
If access points are several years old, consider replacing them with newer, more capable models that support modern Wi-Fi standards.
Update Firmware
Ensure all Wi-Fi access points and routers have the latest firmware installed, as updates often fix bugs and improve performance.

Router/Modem Issues
75%The user's home router or modem might be experiencing intermittent hardware failures or firmware glitches, leading to corrupted network traffic or dropped connections that affect DNS resolution.
ISP Network Congestion or Throttling
60%Your Internet Service Provider (ISP) might be experiencing network congestion during peak hours, or they could be throttling certain types of traffic, which can manifest as intermittent connectivity and resolution problems.
Browser Cache or Extensions
40%Corrupted browser cache or problematic browser extensions can interfere with how websites are loaded and rendered, leading to 'Page Not Found' errors even when the site is accessible.
Malware or VPN Interference
30%Malware on your system could be intercepting or redirecting network traffic, or a VPN service might be experiencing issues with its servers or configuration, both of which can cause intermittent resolution problems.
