How do you tell whether slow internet is Wi-Fi or the ISP?

[Sam]

When a connection gets slow, I’m never sure whether the problem is the Wi-Fi in the house or the internet service coming in. A speed test over Wi-Fi can be affected by distance, walls, or other devices, so it doesn’t seem like a clear answer on its own.

What checks would you do first to narrow it down? Is comparing a wired test with Wi-Fi enough, or are there other simple signs worth looking at before contacting the provider?

Having worked at an ISP... definately wired testing is te best way to check your internet speeds as wifi in 99% of cases is the cause of slowdowns.

Just ensure if your speeds exceed 100meg, that you use a modern device with a gigabit port and that you have a gigabit ethernet cable - some very cheap cables skip some pairs and will only offer 10/100mbit spees.

Sometimes your ISP throttles without telling you as a warning not to download illegal content such as copyrighted movies.

There are other reasons of course.

To do a speed test, head THIS WAY.
