I just installed lubuntu 16.10, replacing the previous Ubuntu 16.04 installation (which in turn replaced Windows XP). I'm running a Gateway MA3 with an AMD Turion 64 CPU @ 2GHz, and 1GB of DDR2 RAM. My NIC is a Broadcom BCM 4311 802.11b/g WLAN (14e4:4311). With my previous Ubuntu installation, it wouldn't recognize it, either. But I had found a Terminal solution that worked like a charm after downloading the specified packages on a Windows 10 laptop and transferring by USB. The commands used were: sudo dpkg -i b43-fwcutter_015-9_i386.tar.deb tar xfvj broadcom-wl-5.100.138.tar.bz2 sudo b43-fwcutter -w /lib/firmware/broadcom-wl-5.100.138/linux/wl_apsta.o sudo modprobe b43 I attempted this with the new lubuntu installation, but it won't work. I get a different output after the third command, kind of like a help message. Then the modprobe returns an error on the location of the b43 file. I tried redoing the third command with the directory it showed me, but I got the same error on modprobe. I can't hardwire a connection, so I'm not sure what to do to get my WiFi working on it. Help?
