To fix most router problems, unplug the router for 30 seconds and plug it back in. That is a restart, it keeps all your settings, and it clears the vast majority of connection issues most people ever encounter. A true factory reset is a different operation: you hold a recessed button until the router reboots, it wipes every custom setting back to factory defaults, and it belongs in a short list of specific situations.
The two procedures have different names, different steps, and very different consequences. Mixing them up is the single most common router mistake.
Restart vs. Factory Reset: Which One Do You Actually Need?
A restart (also called a power cycle) cuts power to the router, clears its temporary memory, and lets it re-establish a fresh connection to your ISP. Your WiFi name, password, port forwarding rules, and every other custom setting survive intact. Nothing is erased. The router simply comes back up in a clean state.
A factory reset overwrites the router’s stored configuration with the original manufacturer defaults. Your custom WiFi name is gone. Your password is gone. Any parental controls, static IP assignments, or DNS settings you configured are gone. You start from scratch.
Use a restart when your internet is slow, dropping, or acting inconsistently. Use a factory reset when you are locked out of the admin panel, when you are selling or returning the device, or when your ISP specifically instructs you to reset. In every other case, a restart is the right call.
| Procedure | How you do it | Settings erased? | When to use |
|---|---|---|---|
| Restart (power cycle) | Unplug power, wait 30 seconds, plug back in | No, all settings preserved | Slow internet, drops, “connected but no internet” |
| Factory reset | Hold recessed reset button 10-30 seconds while powered on | Yes, wiped to manufacturer defaults | Locked out of admin, selling/returning router, ISP instruction |
How to Power-Cycle Your Router (and Modem) Correctly
If you have a separate modem and router, the restart order matters. Bringing them back up out of sequence can cause the router to grab incorrect network settings before the modem has fully reconnected to your ISP.
- Unplug the power cable from your router first.
- Unplug the power cable from your modem second.
- Wait 30 seconds. This clears both devices’ memory fully. Ten seconds is not enough.
- Plug the modem back in and wait roughly 60 seconds until its status lights stabilize.
- Plug the router back in and give it another 60 seconds to finish connecting.
- Test your connection on a device.
If you have a gateway (a single device combining modem and router, common with cable and fiber ISPs), just unplug it, wait 30 seconds, and plug it back in.
Routers run continuously for months and accumulate memory errors and stale connection tables the same way a computer slows down after weeks without a restart. Slow speeds, pages that fail to load, and DNS errors are the most common symptoms a 30-second power cycle fixes.
How to Factory Reset Your Router
Before you start: write down your current WiFi name and password if you want to restore them afterward. Also note your ISP login credentials; find those in the admin panel at 192.168.1.1 or 192.168.0.1 before you reset.
- Find the reset button on your router. It is almost always a small recessed hole labeled “Reset” or “RST,” typically on the back or bottom of the unit. You will need a paperclip, a SIM-card ejector pin, or a toothpick to reach it.
- Make sure the router is powered on. Do not unplug it first.
- Insert the paperclip and press the button firmly.
- Hold it for 10 to 30 seconds. Most modern routers require 10 seconds; some older models need up to 30. Watch for the status lights to flash or go dark, signaling the reset is in progress.
- Release and let the router reboot fully. This takes 2 to 3 minutes.
- Connect using the default WiFi credentials printed on the label on the bottom or back of the router.
Once connected, open the admin panel at 192.168.1.1 and run through the setup wizard. Set a new WiFi name and a strong password (at least 12 characters), then reconfigure any custom settings. If your ISP requires credentials for the WAN connection (common with PPPoE on DSL or some fiber providers), enter those in the WAN settings section. Your ISP can supply them if you do not have them on hand.

What a Factory Reset Erases
A factory reset removes your custom WiFi network name (SSID) and WiFi password. It also clears any guest network, port forwarding rules, parental controls, custom DNS entries (such as Cloudflare’s 1.1.1.1 or Google’s 8.8.8.8), static IP assignments, and quality-of-service settings.
Your devices are untouched. Phones, laptops, and smart home gadgets are unaffected. You will need to reconnect each of them to WiFi once you set the new credentials, because the network name and password revert to factory defaults.
If you have many smart home devices, keep in mind that reconnecting them all takes time. If your issue can be resolved with a restart, try that first. This guide covers consumer routers; enterprise and managed-switch configurations follow different reset procedures.
The “30-30-30” Reset: Skip It
You may come across instructions for a “30-30-30 reset”: hold the reset button for 30 seconds, unplug while still holding for 30 seconds, then plug back in while still holding for another 30 seconds. This technique was documented for a specific chipset in older routers, primarily models running DD-WRT firmware from the mid-2000s.
On nearly every router made since 2010, the 30-30-30 method does nothing the standard hold-to-reset does not already do. Most guides that still recommend it are repeating decade-old forum posts without checking whether the advice applies to current hardware. Some manufacturers have specifically warned it can corrupt firmware on modern routers. Hold the reset button for 10 to 30 seconds with the router powered on, and you are done.
Common Questions
How do I reset my router?
For most issues, unplug the router for 30 seconds and plug it back in. This is a restart and keeps all your settings. If you need a full factory reset, locate the recessed reset button on the back or bottom of the router, insert a paperclip, and hold the button for 10 to 30 seconds while the router is powered on. Wait for it to reboot completely, then reconnect using the default credentials on the router’s label.
What is the difference between restarting and resetting a router?
Restarting cuts power temporarily to clear the router’s memory; all your settings stay intact. A factory reset holds the physical reset button and wipes the entire configuration back to manufacturer defaults, including your WiFi name, password, and any custom settings. They are two separate operations with opposite consequences.
Does resetting a router delete my WiFi password?
Yes. A factory reset removes your custom WiFi password along with your network name and all other settings. The router reverts to the default credentials printed on its label. A simple restart does not touch your password or any other setting.
Where is the reset button on a router?
Almost always on the back or bottom panel. It is a small recessed hole, usually labeled “Reset” or “RST,” specifically designed so you cannot press it by accident. You need a paperclip, SIM ejector pin, or similar thin object to reach it.
Will resetting my router fix slow internet?
A restart will often fix slowdowns caused by memory buildup or a stalled connection. A factory reset rarely fixes speed issues because those usually stem from your ISP, your plan, or WiFi interference rather than the router’s configuration. Try a restart first. If speeds are still slow, run a wired speed test to check whether the problem is in the router or the connection coming into your home.
