Is there a way to debug the connection with a USB730L and the Surf SOHO MK3? The USB730L gives great 4G LTE speeds when plugged in directly to my MacBook Pro, but abysmal speeds when plugged in to the Surf SOHO MK3 located a few feet away. I can’t tell if it is a bug with the router or an issue with the particular cell tower I am currently using. Talking with Verizon support is absolutely useless.
Firmware 7.0.3 build 1260 and Modem Support Version 1022
I would try some Custom Mobile Operator Settings but they are disabled.
