Your pages crawl, video buffers, or a video call keeps freezing, but the Wi-Fi icon still looks connected. Slow Wi-Fi is often a short list of causes: the internet coming into the house is slow, the router needs a restart, you’re on the slower radio band, or the router is in a bad spot.

Work through the steps in order. Router menus and light colors vary by brand, so look for the same idea rather than an exact label. This is for a home network, not a workplace you don’t control.

1. See whether it’s the internet or just Wi-Fi

First, find out what speed you actually pay for. That’s the ceiling. You won’t get more than your plan, and real-world speed is often a bit under it.

Then run a speed test on a site or app you already trust, standing near the router, on one device, with big downloads paused. The FCC recommends checking your current download and upload speeds this way, then contacting your internet provider if they’re slower than expected or if there’s an outage in your area.

If you can, run the same test with a computer plugged into the router or modem with an Ethernet cable. A wired test is the cleanest way to tell the two problems apart:

  • If the wired test is also slow, the problem is likely the modem, the line, or your plan, not the Wi-Fi radio.
  • If the wired test is fine and Wi-Fi is slow, stay on this page and keep going.

2. Restart the modem and router the right way

A restart clears a stuck connection more often than people expect. The FCC notes that powering the router off and back on can resolve a speed problem.

Do this as a power cycle, not a factory reset:

  1. Unplug the power cord from the router. If you have a separate modem, unplug that too.
  2. Wait about a minute.
  3. If you have a modem, plug the modem in first and wait until it looks online. Then plug the router in.
  4. If you have one combined modem-router box, just plug that back in.
  5. Wait until the lights settle, then connect again and rerun the speed test near the router.

Don’t press the small Reset button (it’s often recessed and needs a paperclip). That usually wipes your Wi-Fi name, password, and other settings. For the short version, see Restart the router the right way.

Wait times vary by brand. Some manufacturers say 10 seconds; others say a minute or more when a modem is involved. A minute is a safe middle ground.

3. Check which band you’re on

Many home routers broadcast more than one Wi-Fi network: 2.4 GHz, 5 GHz, and sometimes 6 GHz. They may show up as two names (for example, HomeNetwork and HomeNetwork-5G) or as one name that the phone or laptop picks for you.

In short:

  • 2.4 GHz reaches farther and goes through walls better, but it’s slower and more crowded (other Wi-Fi, Bluetooth, and some kitchen gadgets share it).
  • 5 GHz is usually faster and less crowded, but the signal drops off sooner and is weaker through walls.
  • 6 GHz (on Wi-Fi 6E routers and devices that support it) can be the fastest when you’re close to the router. Older phones and laptops often can’t use it.

If you’re sitting near the router and you’re on 2.4 GHz, switch to the 5 GHz (or 6 GHz) name and test again. If you’re far away or a wall or two over and 5 GHz keeps dropping, 2.4 GHz may be more reliable. See 2.4 GHz vs 5 GHz: which Wi-Fi should I use?.

4. Move the router, or move closer

Placement matters as much as settings. Both the FCC and Microsoft recommend a central, open spot.

Try this before you buy anything:

  • Put the router in the middle of the home, up off the floor, not in a cabinet, closet, or behind a TV.
  • Keep it away from dense walls, metal shelving, and the microwave.
  • Test in the room where you actually work, then a few feet from the router. If it’s fast next to the router and slow in your office, you have a coverage problem, not a “the internet is down” problem.

A range extender or a mesh system can help in a two-story home or a dead corner, but only after you’ve ruled out a bad spot and a stale restart. Don’t start with a new box.

5. Cut the congestion, then check in with your provider

Lots of devices doing video, games, and backups at once will slow a home network down. Pause a large download or cloud backup and test again. If evenings are always worse than late at night, that’s a clue that the network (yours or the neighborhood) is busy.

If a wired test is still slow after a modem and router restart, or your speed is well below your plan when you’re next to the router, contact your internet provider and ask about an outage, a line problem, or whether your equipment is too old for the plan. The FCC also notes that an outdated router may need a firmware update or a replacement to use higher speeds.

What not to do

  • Don’t press Reset on the router to “speed it up.” That’s a factory reset, not a restart.
  • Don’t buy a mesh system, “Wi-Fi booster,” or new router as the first step.
  • Don’t change advanced channel settings until you’ve tried restart, band, and placement. If you do change the channel later, note the original value so you can put it back. Microsoft’s guidance for 2.4 GHz is to prefer channels 1, 6, or 11; many routers also have an automatic setting.

Still stuck?
