Some websites open, but others are blocked on the same Wi-Fi
Request
Most websites work on my Wi-Fi, but one website or one group of sites will not open. The same sites may work on mobile data.
This usually is not weak Wi-Fi. If the same URL opens on mobile data but not on home Wi-Fi, something in the home route may be filtering, resolving, or intercepting that site. The first job is to find where the block follows: the network, one device, one browser, or the website itself.
Use one exact URL and test in this order:
- Open the exact same URL on the same device using mobile data or another network.
- Open the URL on a second device connected to the same Wi-Fi.
- Try one different browser or a private window to rule out an extension.
- If only home Wi-Fi blocks it, sign in to the router and check Security, Parental Controls, DNS, Safe Browsing, web filter, and ISP protection sections.
- If the router points to a custom DNS service, test a known safe DNS setting only if you understand who manages the connection. On work, school, or family-managed networks, ask the admin first.
Do not factory-reset the router before checking filters and DNS. A reset can wipe Wi-Fi names, ISP settings, port rules, and parental controls without proving what caused the block.
If you ask for help, send the browser error text, whether the site works on mobile data, whether another device on the same Wi-Fi fails too, and the router filter/DNS/security page with passwords, public IPs, account names, and Wi-Fi keys hidden.
Stop here if the site is controlled by work or school policy, the router admin page asks for credentials you should not share, the browser error mentions certificate interception, security software you do not recognize appears in the path, or the site is a bank, government, health, or work login page where bypassing filters may create account/security trouble.
