What Wi-Fi speeds can I expect from my extender?

Asked by TechWhiz321
I have a high-speed internet connection at 1 Gbps and I'm using an Ethernet cable from my gateway to a vendor-provided extender. If I'm standing just 20 feet away from the extender in a clear line of sight, what kind of upload and download speeds should I realistically expect?

Itโ€™s one of those things where you canโ€™t give a definitive answer without knowing more detailsโ€”like the extender model and what else might be interfering with the signal.

You can probably expect around 70% of the possible speed, which is decent. If you're not satisfied, consider upgrading to a higher-quality extender for better performance.

It really depends on various factors: the specs of your extender, the device you're using, and even interference from other Wi-Fi networks. Best bet is to check with a speed test.

There are a lot of variables at play, like the type of Wi-Fi standard your extender uses. It might help to know that you can estimate speeds at about 60% of the maximum rate for your connection.

Once I ran a speed test directly to my gateway, I got around 1000 Mbps up and about 950 Mbps down. But through Wi-Fi, it can vary widelyโ€”from as low as 100 Mbps up to around 533 Mbps down.
