So my only option was 1-3MBit/s ADSL in my area, so my only option was Vodafone UK's "Gigacube" which is just a fancy 5G/4G modem/router with a SIM.
The issue is, despite how good 4G can get, as soon as this device is brought inside, not only is it horribly slow, but I get long moments of downtime.
So frustrating, especially when you are doing IT work from home!
Does anyone have any potential solutions that don't include dropping 150+ quid on an antenna booster system??
