One of our Dell Latitude E7240 exhibited strange mSATA SSD behaviour. Disk requests didn’t complete on time. This computer ran the A13 firmware.
The case was eventually solved by upgrading to the A21 firmware executed from an USB stick as the mSATA SSD was unreliable at this point. Apparently, the A18 firmware corrected some mSATA port settings. Also, this was a good opportunity to rid us of Intel’s SA-00075.
This isn’t the first case where disk behaviour suddenly changes to the worst on Latitude E-series laptops, only to be rectified by a firmware upgrade.
Intel Dual Band Wireless-AC 7260 fails to notify Windows 7 when the SSID changes. The result is that the wireless interface retains the previous and possibly invalid IP addresses and other settings. The latest driver, A11, only a few days old, isn’t helpful at all.
I usually avoid installing Intel’s own utility for managing wireless connections, as I feel this should be left in the capable hands of the operating system and the driver. Maybe I should think twice about that.
The current solution is to manually force Windows into releasing and renewing the IP addresses after switching to a different SSID.
