just got a (new to me) Dell Inspiron 15R 5520 with windows 7 32-bit. 1st time using the unit and after connecting to wifi for 2 or 3 minutes disconnects. Troubleshoot and get a driver error. Apply fix, but does same thing again, but this time while attempting fix, it freezes. Do a restore from HDD and lose all drives to access Internet and unable to find drivers anywhere. I have a win7 disc from another pc, that I have used several times with no problems. Try to reinstall OS with this disc, but have the same results. Missing drives. The problem devices list---BCM43142A0-USB PDO6, Ethernet controller(NTPNP_PC10012), Network controller(NTPNP-PC10013), PCI Simple communications controller, SM BUS Controller, USB Controller, and USB2.0-CRW. I have been on ,via a different pc, Dell and downloaded the available drivers to an external hard drive, but am not sure about how and/or where to install. Any suggestions or information would be greatly appreciated.
