  1. Hey David!!

    I’m facing a lot of problems with my network card on the pavilion m4. Could you please help me figure out a compatible network card for it? I am considering an Intel 7260 or a Broadcom BCM943228. I’m particularly worried about the BIOS having a whitelist scheme.

    Thanks in advance.
