I have 5 contracts with three but recently I have been experiencing more and more problems both making and receiving calls at my home. I already have a three box to route calls over my fibre broadband but this does not always happen. I'm fed up with the situation and am looking for advice to see if there is something reasonably priced that would either improve my three signal at the house or ensure that all my calls are routed over WiFi. I must have had the three box for nearly 10 years but currently it just seems so ineffective at the moment. Any ideas what I can do to improve the signal at a reasonable cost?
