It’s a Software Problem
We’re not just talking about your operating system, but sometimes you might have slow internet on one device, not because it’s old, but because it’s infected. If your device has malicious software, it’s possible that it’s causing it to have a slower internet connection, among other problems.
The first thing you need to try is to update your device. You might not be the only one having that issue, and the company behind your device might have already found a solution. The only way you’ll keep your device secure is if you install the software update.
Depending on how infected your device might be, you can just run an antivirus. There are a ton of fantastic antivirus programs you can try, and some of them are free to start using.
You can also reset all the content and settings of your device. This will get rid of all the malicious software it might have, but it’ll also delete everything your device has on it. So make sure you create a backup of your device before you try this.
If you’re not that much of a tech person, you can always ask an expert for help. You can go to your device’s retail store and ask for tech support to help you get rid of any malware you may have.
