Broadcom wireless working but error during boot

[jperrin56]

Hi,

I have an old dell Inspiron 5748 laptop, installed Lubuntu. (Full wipe and install via usb.) Installed the bcmwl-kernel-source, as recommended by the following link:

jperrin@john-inspiron5748:~$ lspci -nn -d 14e4:
06:00.0 Network controller [0280]: Broadcom Inc. and subsidiaries BCM43142 802.11b/g/n [14e4:4365] (rev 01)


Wireless works great, but I get the following error on booting, if I remove the broadcom-wireless-drivers then the error message goes away:

dmesg entry

Any ideas or what to check would be appreciated. Laptop works great with Lubuntu. Good to resurrect my dad's old laptop.

Thank you!
