For a number of years I have been using a product called BT Signal Assist to generate a 3G signal around my house using my broadband wifi since the EE/BT signal in the area I live is very poor even though it is in a middle of a built up area my Mobile bandwidth is typically 2.0Mbps download and around 1.0Mbps upload. This solution worked very well for years and we could recieve and make mobile phone calls anywhere in the house until recently. Since the beginning of August we have been experiencing problems receiving and making call via our mobiles which are on the BT/EE networks, friends and family have said they have rung our mobiles on a number of occassions but have had unavailability message indicating that we are out of signal range even though we are at home, we have even tried having one mobile ring the other mobile in the house with no success. We have Wifi calling set on with both Mobiles but that doesn't resolve the issue. It seems that there is some conflict between using the Mobile signal and the wifi calling option, the mobiles think there is sufficiently strong 4G signal to make the call but that isn't the case On occassions when we are making mobile call it will dropout and we can't connect, very annoying and unuseable.
Any ideas how this can be resolved.... Signal Assist worked well for years but now our 3G/4G/5G mobile phones are useless when we are at home we can't make or recieve reliable mobile calls
