WiFi Connected But No Internet? Here's How to Fix It

WiFi shows connected, signal strength is full, yet websites do not load. This is a different problem from "no WiFi" — your wireless link is fine, but something between you and the internet is broken: DNS, IPv6, ISP routing, a misbehaving DHCP server, or a captive portal that did not load. Each has a clear fix once you identify which one. A tech can rule them out in order and have you online in 20-30 minutes.

Try this first

Real, useful steps to try before you book. If they do not resolve it, the next sections explain what is actually wrong and how a remote session fixes it.

  1. 1

    Try a different DNS

    Set DNS to 1.1.1.1 / 8.8.8.8 (Cloudflare / Google). On Windows: network adapter properties → IPv4 → Use the following DNS. If sites suddenly load, your ISP's DNS is broken.

  2. 2

    Disable IPv6 temporarily

    Many sites have IPv6 issues that hang slow connections. Disable IPv6 on the network adapter properties. If everything starts loading fast, IPv6 routing is the cause.

  3. 3

    Power-cycle modem and router

    Unplug the modem and router for 60 seconds. Plug the modem in first, wait for stable lights, then the router. Refreshes lease and clears stuck states.

  4. 4

    Check for a captive portal

    On guest WiFi (hotels, coffee shops, airports), the network often requires you to accept terms first. Open a browser and try to load a non-https site (e.g. neverssl.com) — the portal usually appears.

What is actually going wrong

Most "connected but no internet" cases come from one of: DNS server failure (your ISP's DNS or a stuck local cache), IPv6 routing issues (the router announces IPv6 but the path is broken), expired or wrong DHCP lease, ISP outage that has not been formally announced yet, a captive portal you have not authenticated to, MTU mismatch causing large packets to drop silently, a VPN client that disconnected and left a partial route, browser certificate or proxy misconfiguration, or — for office networks — a firewall rule that is silently dropping outbound traffic. We have also seen surprising amounts of blame land on outdated wireless drivers and Windows network stack corruption.

What we do in a 30-minute session

Your tech connects through CyberDesk (using your phone hotspot or a different network if needed) and methodically rules out each cause: ipconfig review, ping and tracert tests to known endpoints, DNS resolution test (nslookup), browser-level diagnostics, captive portal check, IPv6 vs IPv4 isolation, MTU test, and proxy / VPN settings audit. The methodology gets you online in the session and identifies the underlying cause so it does not return. If the issue is genuinely your ISP, we tell you exactly what to ask them so you do not waste an hour on the phone with their support script.

CyberDesk encrypted remote session

One-click connect. No software stays on your machine after the session unless you choose to keep it.

You stay in control

See your screen the whole time. End the session in one click. We document what we did when the session ends.

Why trust us with this

No "have you tried turning it off and on again" — we rule out causes systematically. If the problem is on your ISP's end, we identify it specifically (modem error logs, DNS failure, route blackhole) so you can call them with concrete evidence instead of vague complaints. $79 / 30-minute session.

FAQ

My phone has no internet on WiFi but my laptop does. Why?

Different DNS settings, different IPv6 capability, or one device hit a stale DHCP lease while the other did not. We can compare configs in a session and equalize them.

It works for a few minutes then stops. What is happening?

Often a flaky DHCP lease (router reassigns address mid-session), a sleep / wake state on the network adapter, or in offices, a captive portal session timing out silently. We can pin down which one in a single session.

Speed test runs fine but websites still do not load. Possible?

Yes — speed test only confirms the path to that one server. DNS failure, certificate issues, or routing problems to other destinations can still block normal browsing while speed tests pass. We test multiple endpoints to isolate the cause.

My VPN is connected and now nothing works. Same issue?

Similar but different — usually the VPN routed all traffic through a server that is itself broken or overloaded. We check VPN routes, kill switch settings, and DNS leaks. Disconnecting the VPN often immediately fixes it.

I am in a hotel / coffee shop. Public WiFi giving me trouble?

Captive portals are the most common cause on public WiFi. We can also help with the secondary issues — VPN setup so public WiFi is safer, and DNS choice so you do not get redirected to the captive portal repeatedly.
