Hello all--
I'm in a bind trying to reset an older Nether DSL modem. I did a manual
reset on it. It was set up as "pass thru" by me and I want to "undo" that.
When I boot now, the joys of Network Manager!, I can not just enter the
modem manager IP address because I keep getting "network not accessible" .
HELP!
