I thought this might be worth posting for new and existing T-Mobile Home Internet customers. A few have posted concerns about lack of signal strength. I think the following might be evidence of moving in the correct direction. There are several 4x4 (4 cables) antennas for home internet, and I think Waveform and Proxicast (you can find them Amazon).
Watch till the end where Nader Nader posts some before and after data as well as cable connection sequence.
Will you consider making the switch?
