Syslinux - Feb 2018 - syslinux PXE boot version upgrade, network no longer working

Hi David,

it's a shot in the dark, but it might be worth trying lpxelinux.0 [1]
(instead of pxelinux.0) which contains the newer network stack before
falling back to older versions of syslinux.

I believe so.  According to the changelog, syslinux version 5.10 made a
big network stack change which I believe is affecting you.  So you could
also give 5.01 a try.

Good luck

Thanks for the suggestion Lukas. Is lpxelinux.0[1] a fork of this distro or a
completely different open source option?

I can vouch that running 4.07 fixed my issue with older model laptops I
mentioned. I?m still waiting on tests with bleeding new demo models we have to
see if the network loads those as well. I might try an early 5.x release if I
have troubles with the newest hardware.

The file is part of syslinux (pxelinux) and exists since version 5.10.
So neither a fork nor a different project ;) .  According to the link I
had provided:

 Since version 5.10, a special PXELINUX binary, lpxelinux.0, natively
 supports HTTP and FTP transfers, (...)

You probably already have the required file and only need to
change your dhcp configuration to point your clients to a
different boot file (and make sure it's accessible via tftp).

Glad you found an option that works for you.
