ipkg não está funcionando corretamente em dd-wrt

Question

Primeiro tentei instalar o httping , para que eu possa fazer ping em sites. Eu recebi este erro:

ERROR: File not found: //usr/local/lib/ipkg/lists/whiterussian
       You probably want to run 'ipkg update'
ERROR: File not found: //usr/local/lib/ipkg/lists/non-free
       You probably want to run 'ipkg update'
ERROR: File not found: //usr/local/lib/ipkg/lists/backports
       You probably want to run 'ipkg update'
/bin/ipkg: line 1184: sort: not found

/bin/ipkg: line 1184: can't create /jffs//usr/local/lib/ipkg/status: nonexistent directory
/bin/ipkg: line 1184: can't create /jffs//usr/local/lib/ipkg/status: nonexistent directory

       You probably want to run 'ipkg update'
ipkg_get_install: ERROR: Cannot find package httping in //usr/local/lib/ipkg/lists
ipkg_get_install:        Check the spelling and maybe run 'ipkg update'.
/bin/ipkg: line 1184: can't open /jffs//usr/local/lib/ipkg/status: no such file

Então, tentei executar ipkg update . Demora menos de um quarto de segundo para terminar (o que é surpreendente) e, em seguida, eu corro ipkg install httping novamente com o mesmo problema. Então, decidi executar ipkg list e recebo isto:

ERROR: File not found: //usr/local/lib/ipkg/lists/whiterussian
       You probably want to run 'ipkg update'
ERROR: File not found: //usr/local/lib/ipkg/lists/non-free
       You probably want to run 'ipkg update'
ERROR: File not found: //usr/local/lib/ipkg/lists/backports
       You probably want to run 'ipkg update'

Então, como posso consertar isso?

Nota: Eu tenho um Netgear WNDR4300.

Atualização: tentei executar bash e /bin/bash e recebo -sh: /bin/bash: not found . Algo muito estranho está acontecendo aqui.
