Rebooting the router fixes Wi-Fi drops about as well as ignoring a warning light fixes a car. Sometimes it works. Usually it just resets the clock on a fault that turns up again Thursday evening. It's faster to figure out which layer is failing before you touch anything.
One question, asked first
When the connection drops, does everything drop — or just one device?
If every device loses it at the same moment, you're looking at the router, the modem, or the internet service itself. If your laptop drops while the phone next to it keeps streaming, the laptop is the problem: its wireless adapter, its drivers, or its power settings. That one observation kills most of the possibilities, and it costs nothing but paying attention next time it happens.
Note when the drops come, too. Evenings only, or the same hour each day, points at congestion or something scheduled rather than dying hardware.
When it's one device
Update the wireless drivers. On Windows, check the adapter's power management settings — the OS is allowed to switch the wireless card off to save battery, and it doesn't always switch it back on cleanly. Turning that permission off solves a surprising number of single-device drops.
Then forget the network and rejoin it. A stale saved profile carrying an old security setting produces drops that look exactly like a router fault and aren't.
When everything drops
Do a full power cycle, properly. Unplug the router and the modem. Wait thirty seconds. Plug the modem in first and give it a full minute to find its connection. Then the router. Order matters here — a router that boots before the modem has a live line will build its address configuration on nothing.
Now put your hand on the router. Overheating causes a lot of intermittent drops and it's the easiest thing on this list to test. If it's hot, it needs air: six inches of clearance on every side, not inside a closed cabinet, not in a closet, not sitting on carpet or a sofa arm. A good share of "my router is dying" cases are ventilation.
Then log into the admin panel and check firmware. Apply whatever's waiting and let the thing reboot completely — two to five minutes, and don't interrupt it. Outdated firmware genuinely causes instability. It isn't just something support says to fill time.
Still dropping?
Change the Wi-Fi channel. In an apartment building, dozens of networks are fighting over the same handful of channels, and interference looks precisely like this: fine, fine, briefly not fine, fine again. Most routers can scan for the quietest channel, and moving off the factory default is often all it takes.
Think about a DHCP lease conflict, which is a technical way of saying two devices got handed the same address. A reboot clears it for a while; longer lease times, or fixed addresses for the devices that never move, clear it for good.
Then look hard at the modem. A failing modem causes drops that survive every fix above, and the router takes the blame for it. If your provider supplied the box, ask them to check line quality remotely — most can read error rates without sending a van.
Knowing when to stop
If it still drops after a proper power cycle, a firmware update, a channel change, and better ventilation, you're dealing with failing hardware or the line into the building. Both belong to your provider.
Call them with the pattern you wrote down — which devices, what times, what you've already tried. You'll skip most of the script they'd otherwise read to you.
