No Wireless : Broadcom BCM4312 802.11b/g(rev 01)

08:00.0 Network controller [0280]: Broadcom Corporation BCM4312 802.11b/g LP-PHY [14e4:4315] (rev 01)

With all the errors above, the first thing I'd suggest is an update and reinstall the driver. Of course, a wired ethernet connection is required:

sudo apt-get update
sudo apt-get -y upgrade
sudo apt-get install --reinstall bcmwl-kernel-source

Reboot and let us check again:

dmesg | grep wl

Did the update/upgrade and installed bcmwl-kernel-source which seemed successful.
Output from command after reboot

dmesg | grep wl

[26.498618] wl:module licence 'MIXED/Proprietary' taints kernel.
[26.609677] INFO @wl_cfg80211_attach : Registered CFG80211 phy

( This is not a direct copy but should be correct - not up to speed on copying/pasting from terminal yet but found a ref for it)

Thanks Mike

I have a wireless connection !! Brilliant Chili555 !!! Thanks for all your effort - I might take the plunge and remove Windows XP from this Mini Dell - but first I will try a few programs on the dual boot.

So sorry forget the last post forgot to reboot this is the output you should be looking at.
