The WiFi reception is extremely poor at home and also when I’m travelling often and using Sat Nav.

Enter your postcode on the pages I have provided links below and let us know the results.
Check the network coverage in your area:
Check for any network faults/issues in your area:
If there is good indoor/outdoor coverage and no network issues reported in your area then try doing a network settings reset on you phone. What phone do you have?
On my Samsung Ultra 5G device it’s here:
Settings > General management > Reset > Reset Network settings
If there is no to little indoor/outdoor coverage on the coverage map or there is a network issue showing in your area, enable WiFi calling if your phone supports it.
