Dropping is not the same as slow, and the fixes barely overlap. The first job is working out whether the Wi-Fi is dropping or the internet behind it is.

First, find out what is actually dropping. Plug a laptop into the router with an Ethernet cable and leave it running. If the wired connection drops too, your Wi-Fi is innocent and the problem is the modem, the line or the provider. If only wireless devices drop, it is the Wi-Fi. That single test eliminates half the possible causes in five minutes.
Why this happens
1. The router is tired
The most common cause of intermittent dropouts on hardware more than about four years old. Consumer routers run small amounts of memory, and firmware leaks accumulate until the device resets itself or starts evicting clients. The tell is that a reboot fixes it for days or weeks, then it comes back — and that pattern is diagnostic, because a genuine interference or coverage problem does not care whether you rebooted.
2. Channel interference, specifically on 2.4 GHz
If your router has auto-selected a channel that overlaps two neighbors, you get collisions, retransmissions and eventually timeouts that the device reports as a disconnection. There are only three non-overlapping 2.4 GHz channels in the US — 1, 6 and 11 — and in an apartment building all three are usually occupied. Full detail in Wi-Fi interference.
3. Roaming between bands or access points
If you have an extender or a mesh system, devices have to decide when to switch. A device that is deciding badly will hold a dying link until it breaks, then reassociate — which looks exactly like a dropout. It is worse on setups where the extender presents its own separate network name, because the device has to actively abandon one network for another rather than roaming within one.
4. The modem or the line
Cable connections in particular drop when signal levels at the modem drift out of spec — a bad splitter, a corroded connector, a loose coax at the wall. This is invisible from the Wi-Fi side entirely, and it is what the wired-laptop test above is for.
5. One device, not the network
Windows power management routinely turns the Wi-Fi adapter off to save power and does not always turn it back on gracefully. Older Wi-Fi cards also handle modern security modes badly — a router set to WPA3-only will drop some older clients repeatedly. If it is one device, fix the device.
How to tell which one it is
Test
What it means
Wired laptop drops at the same moments
Not Wi-Fi. Modem, coax, or provider — check the modem's signal levels page
Reboot fixes it for days, then it returns
Tired router. Firmware first, replacement if that fails
Drops correlate with the microwave or the evening
2.4 GHz interference or congestion
Drops when you walk between rooms
Roaming. Merge network names, or fix a badly placed extender
Only one device drops; everything else is stable
That device — adapter power settings, drivers, or an old Wi-Fi card
All devices drop simultaneously, no reboot pattern
Overheating router, failing power supply, or a firmware bug

Check the router's own logs before you replace it
Most routers keep a system log, usually under an Administration or Status menu. Repeated "DHCP lease expired" or "deauthenticated" entries point at the Wi-Fi side; repeated resync or downstream-power warnings point at the line. It is the one piece of real evidence available for free, and almost nobody looks at it.
Fixes, cheapest first
Update the router firmware, then reboot both modem and router. In that order, and give each two minutes.
Set the 2.4 GHz channel manually to 1, 6 or 11. Pick the least occupied. Set the channel width to 20 MHz on that band while you are there — wider channels on 2.4 GHz cause more problems than they solve.
Turn off Wi-Fi adapter power saving on the affected device. On Windows, in Device Manager, under the adapter's Power Management tab.
Set security to WPA2/WPA3 mixed rather than WPA3-only. Fixes a specific, common class of repeated dropout on older clients.
Merge your network names, or remove a badly placed extender. An extender with its own network name is a frequent cause of what looks like dropping.
Reseat every coax connector and remove any splitter you do not need. Free, and the usual cause when the wired test also drops.
Replace the router — or the modem, if the wired test failed. Only at this point, and now you know which one.
If it is the hardware
Which box you replace depends entirely on that first wired test. If only wireless drops, replace the router; if wired drops too and you are on cable, the modem or gateway is the suspect. Owning your own modem also ends the rental fee, which on some providers pays for the hardware inside a couple of years — the arithmetic is on the provider pages. And if you are not sure the router is genuinely the problem, do you actually need a new router is the page that will talk you out of it.

Common questions
Why does my Wi-Fi disconnect every few minutes?+−
Test with an Ethernet cable first. If the wired connection drops at the same moments, the problem is the modem or the line, not Wi-Fi. If only wireless drops, the usual causes are an aging router leaking memory, 2.4 GHz channel interference, or a device whose adapter is being powered down to save battery.
Does rebooting the router fix dropping Wi-Fi?+−
Temporarily, and that is the useful part. If a reboot restores things for days or weeks and then the problem returns, that pattern points specifically at a tired router rather than at interference or coverage, which do not care when you last rebooted.
Can an extender cause Wi-Fi to keep dropping?+−
Yes, commonly. An extender that broadcasts its own separate network name forces devices to abandon one network for another rather than roaming within one, and the handover often fails. Merging the names, or removing the extender and testing without it, isolates this quickly.
