Slow internet can drive anyone up the wall. Pages take forever to load, video calls get stuck at the worst moments, and streaming anything turns into a buffering nightmare. But not all of it is your ISP’s fault.
There are router defaults you should fix before blaming your ISP. Similarly, some settings can also free up the bandwidth you already have but are otherwise being wasted. If your first instinct is also to call your ISP and throw money at a faster internet connection, hold your wallets; there are network settings that can fix the problem.
Your DNS might be holding you back
Your ISP’s DNS often isn’t the fastest option
Every time you type a website address into your browser, your device sends a request to a DNS server that translates that name into an IP address. If your DNS server is slow, you’re going to have a slow response, which means websites will load more slowly, no matter how fast your internet connection is. It’s one of the most silent settings that rarely gets touched, but affects your internet browsing experience massively, which is why we don’t recommend using the default DNS on your router.
Switching to a faster, third-party DNS can speed this up. Cloudflare’s 1.1.1.1 or Google’s 8.8.8.8 are two of the most popular and fastest ones you can use. This setting can also be changed at your router’s level so that every device on your network benefits equally. There are tools you can use to find the fastest DNS for your house, and you should employ them to get the best possible results.
Pick the right Wi-Fi channel
Crowded channels kill wireless performance
Network congestion can slow down your Wi-Fi massively; however, it’s easy to fix. As your Wi-Fi signal competes with dozens of other routers and electronic appliances around you, too many devices can pile on the same 2.4 GHz channel, slowing everyone down.
The 2.4 GHz band has only three non-overlapping channels: 1, 6, and 11. Most routers are set to pick one automatically by default, meaning if your router picks a crowded one, your Wi-Fi experience isn’t going to be great, and you’ll get speeds far below what you pay your ISP for.
The solution is to log into your router (generally available at 192.158.0.1 or 192.169.1.1) and switch to channels that aren’t crowded. You can use a Wi-Fi analyzer app on your phone to find less crowded channels, or better yet, switch to 5 GHz or 6 GHz if your router supports it for faster speed and high bandwidth, since these channels are far less congested and offer faster throughput.
Your Ethernet cable could be the hidden speed limit
Older Cat5 cables bottleneck gigabit speeds
I use an Ethernet connection everywhere I can, the reason being network security and the best possible speeds. However, if your Ethernet cable isn’t up to the task, you’ll end up harming yourself. The category rating and type of Ethernet cable you’re using matter more than you think. Older Cat5 cables max out at just 100 Mbps, which means even if you are paying for a gigabit connection, that cable is capping your speed. Cat5e and Cat6 support up to 1 Gbps, while Cat6a handles up to 10 Gbps.
The slowest cable in the chain determines the maximum speed for the entire connection. If you have a mix of old and new cables, even one Cat5 cable creates a bottleneck for everything downstream. If you’re using random Ethernet cables that came with your router or old ones you found lying in a drawer, check their ratings to ensure they’re up to spec. If you can, also avoid using flat Ethernet cables. They look good, but they can hamper your connection without you realizing. It’s a cheap fix that can remove a hardware-level bottleneck you didn’t know existed.
Turn on QoS so important devices get priority
Prioritizing gaming, video calls, and work devices
I regret ignoring my router’s QoS settings for so long, and if you haven’t used them yet, you will too. Quality of Service, or QoS, is a feature that controls how bandwidth is allocated to devices on your network. By default, your router hands off bandwidth equally to all devices on your network, but not all of them require as much. A smart bulb downloading a firmware update doesn’t need the same network priority as your laptop, phone, or gaming console.
Most modern routers will let you assign priority levels to specific devices or types of traffic. You can set up QoS to ensure streaming, gaming, and video conferencing always get prioritized by your router, while devices like smart home devices take what’s left. Not every ISP-provided router offers good QoS controls, though, which is one reason why you should change your ISP-provided router.
Update your router firmware
Firmware updates improve stability and speed
Last but not least, updating your router’s firmware can fix problems like magic, including internet connectivity or speed issues. Just like any other device, your router runs software, and outdated software can bring bugs, compatibility issues, and security vulnerabilities that can directly impact internet speeds. Some ISPs handle router updates automatically, but that may not be true in your case, especially if you’re using your own router instead of renting one from your ISP.
Check your router manufacturer’s website or companion app for the latest firmware version, and if there’s one available, update your router right away. Some routers have an auto-update toggle buried deep within the settings you can enable and forget; others require you to manually update every time a new firmware version launches. Regardless, running updated firmware can improve stability, fix connection drops, and sometimes even unlock better speed handling for newer Wi-Fi 6 or Wi-Fi 7 devices on your network.
Your router settings matter more than your internet plan
Before you spend money on a faster internet plan, it is worth spending some time tuning your network for better optimization. Not all router defaults and ISP configurations are best for your specific conditions, which is why tuning your network to your needs often yields better results than a generic configuration.
I Use These Tricks to Get the Fastest Internet From My Router
This is how I get faster speeds without upgrading my internet plan.
Once you’ve optimized your network, you will have a much clearer picture of whether your current plan is actually the problem. If you still decide to upgrade, at least you will know your home network is ready to use every bit of that extra bandwidth you’re spending your hard-earned money on.
