I haven’t had the best luck with ISPs. In fact, I’ve been fighting them for over a decade now. But even I know that often, connection issues aren’t caused by your internet service provider—they’re caused by small mistakes related to your network.
Before you spend half an hour on the phone, fruitlessly arguing with a customer service rep, make sure you’re not affected by these common networking problems.
Your ISP may be the problem, but it doesn’t have to be
I’ve gone through more ISPs than most people, but I don’t automatically blame the service provider
Listen, I’m far from the biggest fan of internet service providers. If anything, I’m quite the opposite; I’ve grown jaded after a number of bad experiences. One of my worst ones included an ISP that disconnected up to 50 times per day, but still demanded $1,000 to let me break the contract and change to a different provider.
But, as much as I dislike many ISPs, I know that oftentimes, we, the users, are to blame here. And more often than not, it’s something entirely silly and very fixable.
That’s great news. You don’t want a bad connection to be in the hands of anyone other than you. If it’s in your power to fix, all the better.
The problem is that a lot of home networking fails look exactly like ISP fails from the outside. Slow speeds, disconnects, random buffering, a TV or another smart device that keeps disconnecting … I’ve been there.
And yes, the ISP absolutely can be the problem. But doing a little bit of troubleshooting first can help you save time and optimize your connection without ever involving a third party.
4 common home networking mistakes that could be wrecking your connection
The rare occasion where “it’s not you, it’s me” applies
A lot of the most common networking-related mistakes are invisible to the end user. Sometimes, it’ll be settings. Other times, things like router placement. It’s often not immediately obvious, but it’s always worth investigating.
Here are the 4 most common issues that aren’t related to your ISP.
1. Bad placement is hurting your Wi-Fi
When it comes to Wi-Fi connections, router placement matters so much more than you might think. Expecting one router to deliver perfect speeds and stability all throughout the house is already a lot to ask for. But it’s even more of a tall order to expect it to offer perfect coverage if it’s shoved into a cabinet, tucked behind furniture, or blocked by walls. Even mesh nodes work best when they’re placed partway toward the weak area instead of right inside the dead zone.
The easiest way to check is to test your connection right next to the router and then again in the room where things go wrong. If speeds, latency, or stability fall apart with distance, move the router into a more open, elevated spot and place mesh points closer together, ideally no more than about two rooms apart and with as clear a path between them as possible.
To test your connection the proper way, run the same speed test on the same device in two places: right next to the router and then in the room where your connection usually goes bad.
2. Your radio settings are working against you
Your router’s radio settings control things like band, channel, and channel width, and bad choices here can make a perfectly good internet connection feel like a nightmare. Apple specifically recommends using 20 MHz on the 2.4 GHz band to avoid performance and reliability problems, while leaving channel selection on Auto is usually the safest bet unless you have a very specific reason to override it.
To check this out, open up your router settings and look for manually forced channels, odd band settings, or 40MHz on 2.4GHz.
Fix this by enabling all supported bands. Leave channels on Auto if your router plays nicely with that, and keep 2.4GHz conservative so it can do what it does best, which is range, not speed.
3. Your SSID choices are making devices misbehave
An SSID is just your Wi-Fi network name, but how you use it affects how well your devices connect and roam. It’s good to use a single, unique SSID across bands. Hidden SSIDs bring no real security benefit, and creating too many SSIDs adds management overhead that eats into the airtime your devices could be using for actual data.
If your network list includes a bunch of variations like separate 2.4GHz and 5GHz names, a hidden main network, plus some random extra networks, you’ll get confused and may get stuck with the worst option on the device that needs the best one. A good fix is to consolidate to one main SSID, keep a guest or IoT network only if you need it, and disable hidden SSIDs.
4. Your router configuration is creating its own problems
A classic example is double NAT, which happens when both your ISP gateway and your own router are doing NAT at the same time, and that can break or complicate things like gaming, port forwarding, and device-to-device communication.
You can look for signs of this by seeing whether both boxes on your network are acting like routers, especially if both are broadcasting Wi-Fi or handing out IP addresses. The fix is to put the ISP gateway in bridge mode when possible, or switch your own router to access point mode, then make sure your Wi-Fi security is set to WPA3 Personal or WPA2/WPA3 Transitional.
Investigate first, call to complain second
It’ll save you so much time
When I have internet issues, am I tempted to just go ahead and call my ISP right away? Yes, often. But I’ve also been more unlucky than most people when it comes to internet connections, and with that in mind, I stop myself short of picking up the phone.
I start by investigating. Simple settings can wreak havoc. For instance, certain router or Windows settings, such as Energy Efficient Ethernet, can cause their own problems—and those issues can make or break your internet connection, or at the very least, affect its speed and stability.
I also try to narrow it down before calling my ISP. Does it happen on every device or just one? Is it Wi-Fi, or are wired connections also broken? Is it everywhere in the house or only in one room? All those checks are a good start.
The sooner you know what caused it, the better
If your internet acts up once or twice, that can happen to anyone. In those situations, there’s almost no point launching into a deeper investigation. But if something becomes a regular problem, start digging. If none of the above help, call your ISP and involve them in your problem-solving—it might be something on their end, after all.
