Dear All,
i have router borde 1100AH after made upgrade from 5.20v to 6.18v i face this problem,when i do resetart or power of for this router it remains restarting for long time ,one hour, after that it backs to work.
i made reupgrade but problem still active,i made the same upgrde for another router 1100ah2x and i didnot face any problem.
Do you by any chance have the dude package installed on this routerboard ?
The model are exactly RB1100AH (and the other successfully upgraded RB1100AHx2)?
You do not have provided any relevant detail, like what package are installed and active before the update, and the exact way you have used to upgrade 5.20 to 6.18.
You use IPsec on RB1100AH?
One hint: next time install last 5.x available, then the last 6.x
