please I bought an edimax EW-7811Un usb wireless adapter. from my pi console, after connecting the usb wireless adapter to my pi, I discovered the firmware I should download for my debian wheezy is the firmware- realtek. I downloaded these package firmware-realtek_0.36+wheezy.1_all.deb, copied to a usb, plugged the usb to a power usb hub plugged to pi. every other necessary connection was in place. typed sudo apt-get install firmware-realtek_0.36+wheezy.1_all.deb, it returned
: unable to locate package firmware-realtek_0.36+wheezy.1_all.deb
:couldn't find any package by regex ' firmware-realtek_0.36+wheezy.1_all.deb '
please can anyone be of help. I want to connect the pi to a wireless network, the only network I can connect to. I got my usb wireless adapter, and it's supposed to be compatible with the pi. I don't know what am doing wrong. cheers
