opkg

When I telnet opkg update, I am getting this error:

root@dm7020hd:~# opkg update

-sh: opkg: command not found

root@dm7020hd:~#

I think I messed up something...

I had to do a fresh install....on opelpli8star...

This was due trying to configure my usb wifi dongle....

In the image there are various drivers installed for this dongle...even the one I was looking for r8712u

Should I uninstall the other drivers like 8188eu and 8192c and 8192cu and 8192eu.... could they be conflicting as I could not bring the dongle to communicate with the 7020HD.

Thanks
