I live in a rural area and do not have access to internet other than through cellular. I have used a Surf SOHO tethered to a MiFi box for the last 5 years. This setup worked well for some time, but recently the surf SOHO started to crash and lose wifi (plugged in connections still worked) about every day requiring me power it down and back up. I updated the firmware from 7.1 to 8.1 and that did not fix the issue. I enabled the watchdog, and it seems to recover on its on now, but it is still going down. I could be wrong, but I assume it is a HW issue. It is 5 years old and had been more or less trouble free until recently. I considered just buying another SOHO, but I noticed that the MAX line is now available where I could put the SIM card directly in the unit and skip the tethering. Eliminating a piece of HW is attractive to me. My situation requires wireless over a very large area (house and a couple of barns) I liked the range of the SOHO (I ran it on Max & Boost)) and would want as much or more with the new setup. The unit is located in my attic, I have 2 external cellular antennas hooked to the MiFi and the MiFi is tethered to the SOHO.
Will the MAX units have as good or better WiFi range as the SOHO?
If so, which MAX unit would have the best range?
