I was naive, and upgraded the firmware on two of my wrv200 routers. They are now at 1.0.39. I thought it was the right thing to do. However, I then came across this forum, and have read that I should have first reset to factory defaults, upgraded the firmware, and then reset back to defaults again. If I had reset to factory defaults, that will wipe out the changes rights? Also, if I have screwed up by just uploaded the file, can I hold the reset button on the router for 30 secs, and then upload the latest firmware?
