That sounds very like the phone is staying on the 2.5GHz band instead of the 5GHz band that allows more bandwidth. Try turning off your phone completely, then turning it on again very close to the Hub. What speed do you get then?

It would be helpful if you could tell us 

1. What are you trying to do - texts, emails, watch video ? 

2,  What is limited - WiFi connection, speeds, intermittent?

Hi, 

Sorry should have given more info.

just installed virgin fibre broadband, all other devices on Wi-Fi speed test at around 384mbs download. speed test on Samsung gives 20.8mbs.

virgin media connect app says speed is “fast” and “limited connectivity”

Thanks

The Samsung A12 has WiFi on the 2.4Ghz b/g/n band.

With a strong signal 50Mb/s should be possible.

Does it not have 5GHz? Must be an old device.

Those are the mobile network frequencies. WiFi bands are not mentioned.

Apologies for only posting the mobile bands.

Again from the gsm link, the broadband capabilities are

WLANWi-Fi 802.11 b/g/n, Wi-Fi Direct

 

So the A12 only supports the 2.4GHz bandwidth

It's an on-going source of confusion.   5G mobile <> 5GHz WiFi
