When transferring files between my two computeres over wireless it starts out transferring at 1.5mbs, but then quickly drops to 150kbps. I have an inspiron n5010

Here is my lspci output, do I have the right drivers installed?

Hi,

please show

lsmod
Did you install the Broadcom-STA driver? If yes, blacklist the modules brcmsmac, bcma, and brcm80211 and reboot. If not, blacklist them, too, and install it. Also reboot after that
