heya i installed the following:

OpenWrt Firmware
Kamikaze (r14959)
Load: 0.02 0.04 0.01
Hostname: OpenWrt

onto my tl-wr941nd router, however this firmware doesn't allow me to upgrade using the web interface.
So i did this: http://wiki.openwrt.org/oldwiki/openwrt … lling/tftp to return my factory firmware
no success, so now i want to slow down the boot, so i did this: http://wiki.openwrt.org/oldwiki/openwrtdocs/bootwait - i used a program called putty to gain access to the routers ssh, logined in fine.

i tried:
nvram set boot_wait=on
the console spits out: -ash: nvram: not found

i tried:
  set boot_wait on
nothing happens, i then tried:
  set nvram boot_wait
nothing happens

i then tried:
  nvram get boot_wait
the console spits out: -ash: nvram: not found
i then tried:
  get boot_wait
the console spits out: -ash: get: not found

no success

help?
