This is fixed in at least v4.00.7 and above. Your original command doesn't
work, the file doesn't even exist. But redoing it as such:
curl -d "submit_button=WL_WPATable" -d "change_action=gozila_cgi" -d \
"submit_type=" -d "action=" -d "security_mode_last=" -d "wl_wep_last=" -d \
"security_mode=disabled" http://192.168.1.1/apply.cgi
Results in "Authentication Required". (The strings were grabbed from
ethereal, as I disabled the security, which would explain the multitude of
empty options,
but whatever.) This is an old bug that was fixed, which should explain the
lack
of vendor dialog. Upgrade, upgrade, upgrade. :)
I wish I could upgrade. The latest firmware revsion for my router is 1.0.9.
Your router and mine may have the same name, but there the similarity
ends. Flip your router over to figure out which hardware revision you have.
Mine is the v5. Yours is probably v4 or earlier.
I'm told that there was a major change in the router between v4 and v5. v4
and earlier were based on linux. v5 and later were based on VxWorks.
Linksys appears to have introduced this bug when they made that switch.
Thanks for your testing.
