Good day, we are trying to netboot an RB1100AH using netinstall 6.39.1.exe. We have serial into the MT working fine, and can get the RouterBoot menu, but every time it tries to request bootp there is no answer from Netinstall application.

We can run wireshark and see the bootp request packets from the MT arrive at my laptop and all, just no reply from the app. :/

We have all other laptop interfaces besides Ethernet disabled.

Ethernet has a static (10.214.28.1/24) IP with gateway (10.214.28.254), we have pressed the "netboot" button on netinstall app and enabled the boot server, and put 10.214.28.99 into the IP field there.

Windows firewall is turned off for all domains.

All tutorials we can find about Netboot suggest that the router should react to seeing a boot server by ending it's search for one at least, and the netinsall app should show the router and it's mac address in it's list of Routers/Drives. But that's the step we're getting stuck at because the app and device do not appear to see one another.

Any suggestions? If you were trying to revive an RB1100AH and ran into this issue, what might you do?

Thank you for your time and have a great Memorial Day!

I assume you're using ether13?
Which OS? physical install or it's a VM?

Have you tried using a different laptop? A different ethernet on the laptop (USB for example)?

Yep, I don't even see the bootp packets unless I connect to ether13. :3

Laptop is Windows 7 with no VM involved, MT is either RB v5.x or v6.x.. but 5.x more likely. Though I doubt we're getting that far. I could look up the bootloader version but I feel like the packets not being responded to on the Windows side is the most reasonable place to focus.

I will try another laptop's ethernet port and report back on how that looks, thank you.

but I feel like the packets not being responded to on the Windows side is the most reasonable place to focus.

Yes, looks like. That's why I suggested trying a different system or network adapter.

Sometimes this is due to specific ethernet drivers, or the network subsystem being tampered with (trojans, firewalls, security programs, etc).

MT is either RB v5.x or v6.x.. but 5.x more likely.

Have you tried with netinstall-5.26?

Why are you trying to netinstall it? Assume you are you trying to revive it?
