I've just added a CarStick and my first impressions are not that great. It always has a weaker signal than my phone and only ever shows 3G. See Below:
I was under the impression it would use a better aerial in the car to give a stronger signal to be a useable Wi-Fi hotspot in the car as well as use the Car-Net features.
Has anyone else got one or tried one to compare with my findings, I'm wondering whether I have a faulty stick or aerial?
