Experiencing intermittent wireless connectivity issues after upgrade to windows 10;  Have an Inspiron 5748 with Broadcom 1704 adapter.  Driver is up-to-date: 7.35.295.0.  Diagnostics show no problem with device.  Will usually successfully connect to network, but the connection will get dropped intermittently.  Using troubleshooting to fix does result in restoring connectivity, but it will subsequently drop again intermittently.  Never experienced any issues prior to windows 10 upgrade.
