Press any key within 2 seconds to enter setup..
kernel not found
trying bootp protocol..........................................................

When I close netinstall messagebox error, a program close and lose all configured parameters.
PC and routerboard are properly connected to 3com switch and nullmodem cable is the same I normally use to configure other devices. My computer is a XP SP3

Someone can help me (sorry for my little english)

Eliminate the 3com switch and plug directly into your laptop ethernet port.

Also make sure that your ethernet MTU is set to 1500 and not anything less.

Tank you very much r0c, problem solved and routerboard full operative :smiley:
Tomorrow I go to install this routerboard (to offer free internet connectivity trough a italian WISP “Air2bite”) on a camp in Abruzzo - Italy (where there was an earthquake) and I thank you on their behalf
