Although I was on
Needles and Pins (pun intended), I just upgraded from 74.4SF to 77SF successfully.
The only nit was when I uploaded 77SF to the 7800, I got a warning that said:
192.168.1.1 says: Warning! You are trying to download firmware with version V1.0.2.77SF which is older than the firmware with version V1.0.2.74.4SF you had. Do you want to continue?
I clicked
OK and the install process completed successfully.
The surprisingly nice aspect to the firmware upgrade was that the nvram did not cause problems like it had when I upgraded to 74.4SF. The router retained all it settings. BTW, I am not running any other software provided by other snbforum members to get around the nvram content retention issue.
Prior to today's firmware upgrade, I momentarily lost power on Friday night (during some local riots). The 7800 rebooted without issue with 74.4SF. I had expected it would have the nvram retention issue and lose its settings.
The only difference I can recall is that I disabled the Traffic Meter (TM) after I installed 74.4SF and setup the 7800 back in March. TM with DST enabled was causing Shield's Up All Service Ports test to fail.
With 77SF, I just ran Shields Up All Service Ports test with TM disabled and DST enabled. It passed. I have no practical use for TM and will never enable it again.
I'm glad I was able to upgrade to 77SF without hassles.
THANK YOU Voxel!
