I’m new to T-Mobile’s Home Internet service. I only have about 2 bars connectivity inside my house (3 bars outside). The download speeds are consistently >100MB/S, but the upload speeds are too often <3 or even as low as 1.5 MB/S. I have moved the device to different rooms and into different orientations with no improvement. Would an external antenna or positioning outside (within a weather enclosure) improve my upload speed experience?
