Why Is My Internet Speed So Much Slower Than What I'm Paying For?

Asked by CoolWave87
I'm using AT&T Internet Air and their website states I should get a minimum speed of 90 Mbps. However, I'm only hitting about 10 Mbps when downloading on my computer without an Ethernet connection, and only up to about 20 Mbps with it. I've tried placing the device in the best spot in my apartment. Are there specific settings I can adjust to improve my speed?

It's rough, but AT&T's Internet Air often struggles to reach advertised speeds. If youโ€™re seeing 10-20 Mbps, thatโ€™s unfortunately a common issue unless youโ€™re in an ideal spot for coverage.

To improve things a bit, try testing speeds at different times of the day. Speeds can fluctuate based on network traffic! Also, knowing your precise WiFi protocol can help diagnose speed issues. You might need to upgrade your equipment depending on what you're using now.

CoolWave87: That sounds like a plan! Iโ€™ll try testing at different times and look into my WiFi protocol.

AT&T Internet Air is a wireless service, and it's generally recommended to use a wired connection for better speeds. Also, make sure you check the actual bandwidth your device supports. Some older devices cap at around 11 Mbps, which may lead to disappointing speeds.

CoolWave87: Thanks for the tip! I didn't realize that older devices could affect my speed.

You can also look into other local ISPs. Sometimes there are better options out there if your current service isn't meeting your needs. Also, check your WiFi setup; it can make a big difference too!

There's some misleading info out there. AT&T mentions typical speeds between 90-300 Mbps but doesnโ€™t guarantee them. About 25% of users might see slower speeds, depending on various factors like network congestion. They advise checking your specific area's data and connection type for more accuracy.

CoolWave87: I see what you mean. I should've read those details more thoroughly.
