Netgear Router Slowing Down Your Internet: Fixes

Find out where the slowdown actually is

A Netgear router gets blamed for a lot of slow internet, and sometimes it deserves it. But the router is only one link in a chain: your provider’s connection, the modem or gateway, the router, the Wi-Fi radio link, and finally the device you are using. Fixing the wrong link wastes time, so it helps to test each one.

Run these tests in order and write down the results. Use the same speed test site or app each time, and close other downloads and streams first.

Modem or gateway directly. If your setup allows it, connect a computer by Ethernet straight to the modem (some providers need the modem restarted to accept a new device). If the speed is already low here, the router is not the cause. Contact your provider.
Computer to the Netgear by Ethernet. If this is much faster than Wi-Fi, the router’s wired side is probably fine and the problem is wireless.
Same device on Wi-Fi, close to the router. Test in the same room as the router, on both the 2.4 GHz and 5 GHz networks if your router shows them separately.
Same device on Wi-Fi, in the room where it is slow. A big gap between steps 3 and 4 points to distance, walls or interference rather than the router’s settings.

Keep in mind that Wi-Fi speeds are normally lower than a wired test, and the result varies with the device. Phones and laptops with older Wi-Fi hardware may never reach the plan speed on Wi-Fi, even with a good router. If you want to know what speeds to expect, our Wi-Fi router speeds chart explains the headline numbers on router boxes.

Restart the router and modem properly

A simple restart is a reasonable first step if the slowdown started recently. Turn off the modem and the router, wait about 30 seconds, turn on the modem first, wait until its lights settle, then turn on the router. If a router needs to be restarted every few days to stay fast, that can be a sign of overheating, overload or a firmware problem, covered below.

Check cables and the connection between modem and router

Use the Ethernet cable that came with the router, or a newer Cat5e or Cat6 cable. Very old or damaged cables can limit the connection to slower speeds or cause errors.
Make sure the cable from the modem is in the router’s Internet (WAN) port, not one of the numbered LAN ports.
If you have a gigabit plan, check that the link is running at gigabit speed. Your computer’s network settings usually show the link speed. A link stuck at 100 Mbps is a common hidden bottleneck.

Update the router firmware

Netgear releases firmware updates that can fix bugs and performance issues. Log in at routerlogin.net (or the router’s IP address), and look for the firmware update option (our guide on how to tell if your router needs an update helps), typically under Advanced and Administration. Newer Nighthawk models may also use the Nighthawk app. Do not unplug the router during an update. If your model no longer receives updates, that is worth noting when you decide whether to replace it.

Review settings that can limit speed

QoS (Quality of Service). If QoS was set up for an older, slower plan, it may still be capping speeds. Try turning it off or re-running its speed check, then test again.
Parental controls and traffic meters. Content filtering and traffic monitoring features can add overhead on some models. Try disabling one at a time to see if speeds change.
VPN or similar router features, if enabled, can reduce throughput on lower-powered models.
Wi-Fi mode and channel width. Make sure the router is not set to an old mode that forces slow speeds. Leaving the channel setting on Auto is usually fine.
MTU. This rarely causes slow speeds on its own, but a wrong value can cause odd problems. See our guide on changing the MTU on a Netgear router before changing anything.

If you change several settings, change one at a time so you know which one made a difference.

Fix wireless problems

If wired speeds are good but Wi-Fi is slow, work on the wireless side.

Placement. Put the router in a central, open, raised position. Avoid closets, floors, and spots behind a TV or next to large metal objects or aquariums. Microwaves and cordless phones can also disturb the 2.4 GHz band.
Use the 5 GHz band for devices that are reasonably close to the router. It is usually faster at short range, though 2.4 GHz travels further through walls.
Change channels. In a crowded apartment building, a neighbor’s network on the same channel can slow yours. Try a different channel and test again. Read dual-band vs tri-band routers if you are unsure which band suits which device.
Check the device. An old laptop or phone with an older Wi-Fi standard will be slower than a new one on the same router.
Extend carefully. If one part of the house is weak, a mesh system or a wired access point is generally a better fix than a cheap repeater, which can cut speeds noticeably (see Wi-Fi repeater vs bridge).

Too many devices or heavy users

Several people streaming, gaming and downloading at once can use up a plan’s bandwidth, and a lot of connected gadgets can strain a weak router. Check the router’s attached devices list and see what is active. Our guides on how many devices a router can handle and on a router crashing with too many connections go further into this.

Is it the router, the modem or the provider?

If your direct modem test is slow, the router is not the problem. If it is fast but the router is slow even over Ethernet, the router (or its settings) is the likely cause. If you have more than one router in the home, that can also cause issues; see whether multiple routers affect speed. For a broader look at where each device fits in, read does your router or modem affect internet speed.

Is my Netgear router outdated?

Routers do not stop working on a particular date, but they do age. Signs that a Netgear model may be holding you back include:

It only supports Wi-Fi 4 or an early Wi-Fi 5 standard while your devices and plan are newer.
Its Ethernet ports are limited to 100 Mbps, or it cannot keep up with your plan speed even over a cable.
It no longer receives firmware updates.
It needs frequent restarts to stay stable.

Check your exact model number on the label and look up its specifications and support status on Netgear’s website. Replacing the router is sensible if it cannot match the speed you pay for, but run the tests above first so you do not buy a new router for a problem that lives elsewhere.

When to contact your provider

If a direct connection to the modem is consistently far below your plan, or speeds drop at the same time each evening, contact your internet provider. Ask them to check the line signal and whether your modem is supported for your plan speed. Slowness can also come from provider congestion or outages in your area, which no router setting will fix.

Quick answers

Why is my Wi-Fi slow when the plan is fast? Wi-Fi shares the air with neighbors and loses speed with distance and walls, and many devices cannot reach full plan speed on wireless. Test by Ethernet to compare.

How do I test my Netgear’s speed? Run a speed test by Ethernet from the router, and again on Wi-Fi from a device nearby. Compare both to the modem-direct result and to your plan.

Can resetting to factory defaults help? It can clear a bad configuration, but you will lose your settings, including the Wi-Fi name and password. Try the other steps first and note your settings before you reset. Our guide to factory resetting a Netgear Nighthawk has the steps.
