my attempts to upgrade the firmware on our linksys NSS4000 fail. after selecting the downloaded image NSS4000_fwupgrade_0116.tar.gz in the management tool and hitting "upgrade firmware" I get a "downloading image" message, then it says "programming image" - and stalls. it never recovers from that screen. a second http-session on the NSS4000 after some minutes shows that there has been no firmware update, it is still displaying firmware verion 1.12-3 (and did not reboot).
what do I do wrong? do I need to install the patches version on version until I reach the concurrent 1.16, in other words, might it be impossible to skip the patches between 1.12 and 1.16?
any help is appreciated. thanks in advance,
