WiFi is connected but slow: 6 things to check before calling anyone

Slow WiFi that still shows as "connected" almost always comes down to one of three things: too many devices straining an older router, a coverage gap in a specific room, or evening congestion from nearby networks, not a broken connection. Working through the six checks below in order will tell you which one you're dealing with, rather than guessing or paying for a bigger internet plan that won't fix it.

First, figure out if it's actually your internet or your WiFi

This is the single most useful distinction to make before anything else. Run a speed test on a device sitting right next to the router, connected by the same WiFi you're troubleshooting. If that result matches what you're paying for, your internet connection is fine and the problem is how WiFi is reaching the rest of the home, a coverage issue, not an internet issue. If the speed test is slow even right next to the router, the problem is more likely upstream, your actual internet connection or the router itself, not distance or walls.

Six things worth checking yourself

Run the near-router speed test described above, this single check tells you which half of the problem you're actually dealing with. Check how many devices are connected in your router's app or admin page, an older router straining under 20 or more devices will slow down for everyone, especially with several doing anything bandwidth-heavy at once. Restart the router itself, not just your device, a surprising number of slowdowns clear with a simple reboot since routers accumulate minor performance drag over long uptime. Check if it's one specific app or streaming service acting up while everything else feels normal, that points to the service itself, not your WiFi. Check the time of day the slowness happens, consistently worse in the evening usually means congestion (either inside your home or from neighboring networks), not a hardware fault. Move closer to the router temporarily and see if speed improves, if it does, that confirms a coverage problem rather than a connection problem.

When it's a router age problem

Routers provided by internet providers are often basic hardware, adequate at launch but struggling a few years later as homes add more connected devices. If your router is more than three or four years old and slowness has crept in gradually rather than appeared suddenly, hardware age is a likely cause: a router from before 2018 predates WiFi 6 (802.11ax), the standard the Wi-Fi Alliance introduced that year specifically to improve handling of many simultaneous devices on one network, which is exactly what a growing household adds over time.

When it's a coverage problem, not a speed problem

If your near-router speed test is fine but a specific room is slow, that's not really a 'slow WiFi' problem in the sense most people mean, it's a coverage gap, and no amount of internet plan upgrading will fix it. This is one of the most common and most avoidable wastes of money we see: upgrading to a faster internet package when the actual bottleneck is signal strength in one part of the home, which a faster plan does nothing to address.

When it's genuinely your internet connection

If speeds are slow even right next to the router, check for an outage notice from your provider first, since this is sometimes simply outside anyone's control temporarily. If there's no outage and this persists, it may be worth contacting your ISP directly, or having us test the connection at the modem itself to confirm whether the issue is really the incoming connection versus something on the home network side.

What we test on a visit

We measure actual speeds at the router versus the modem to isolate whether the issue is your WiFi network or your internet connection itself, then work outward from there, checking device count, channel congestion, and coverage room by room. It's usually a straightforward, fairly quick diagnostic that saves guessing and stops you paying for a bigger internet plan that wouldn't have fixed the actual problem.
