Irrespective of the firmware update either 26 or 29 is too low, 29 may officially be the bare minimum to get any sort of connection but the practical minimum is at least double that, at 32dB and ideally 35dB+

This sounds like a pretty common (and lame) failure mode for badly programmed NAT tables.
