CA worked with two omni antennas without issue. Signal strength is a bit weak (64%), but am able to lock onto B41 and get CA. Speeds now ~45 down, 4 up. Download is obviously way better, but up is much lower than B26. I assume this is due to weaker signal strength. I'm happy with this as I don't ...

Got it sorted out.

Flashed generic firmware for the mc7455, and then switched to qmi and everything started to work again.
