Fix slow UFO speeds

No ratings

UFO delivers speeds of around 900Mbps straight into your home, but even the best devices have limits to the speeds they can manage. Most smartphones and tablets have small antennas and batteries built in with other components, which limits their ability to transmit and receive Wi-Fi signals. 

Some older devices only support 2.4GHz - a wireless frequency that is more susceptible to signal interference. Newer devices usually support 5GHz, which is faster, but has its limits. To put this into context, take a look at the maximum wireless throughput speeds you can expect on your devices on each frequency band.


Device Maximum speed
2.4Ghz 5Ghz
iMac Up to 150Mbps Up to 500Mbps
MacBook Up to 150Mbps Up to 500Mbps
PlayStation Up to 100Mbps Up to 300Mbps
PC Up to 100Mbps Up to 250Mbps
iPhone Up to 100Mbps Up to 250Mbps
Android Up to 100Mbps Up to 250Mbps
Xbox Up to 100Mbps Up to 100Mbps
Windows phone Up to 100Mbps Up to 100Mbps
Blackberry Up to 50Mbps Up to 50Mbps


Laptops and computers generally have better capacity for higher speeds than smartphones and tablets, however, there are many different factors that affect Wi-Fi speed. In reality, you'll only be able to achieve speeds near 900Mbps over Wi-Fi if you're using a high-spec computer with the very best wireless technology, in close range of your router.

If you're using a device with a lower spec, there are still some things you can do to get better speeds. Take a look at our tips below:

  • For the best possible speed, connect your device directly to your router using an Ethernet cable. With no interference from external signals, a wired connection will always be faster than Wi-Fi.
  • If you're using Wi-Fi, make sure your router is upright and facing into the room. Put it in an elevated position on a table or shelf, and make sure it’s not blocked by any furniture, ornaments or books.
  • Electrical appliances like Bluetooth speakers, cordless phones, and baby monitors can disrupt your Wi-Fi signals. You should switch these off when they're near your router or move them away if you can. 
  • If your Wi-Fi gets slower when you're far away from your router, our Wi-Fi Extender Kit can help by making your signal go further.
  • If you're tech-savvy, you can also try changing your wireless channel
