Re: [netopia] Netopia 3347 AT&T FW upgraded to 7.8.1R2. How did
That page seems to be out-of-date, as they show the latest firmware for the 3346N-002 as 7.4.0 R6, but other sites identify the latest as 7.5.1 R10-DP42. After having installed the 7.5 firmware, I don't know if it is possible to go back to 7.4.
The best thing would appear to use the 7.5 firmware for a month or so; if it works OK, I won't concern myself any further.
