A client's PC is having intermittent issues connecting to WiFi networks (at home, work, etc) ever since a recent trip to east Africa.
Here's what happens and what I've done (with result):
When the client connects to a wireless network since their recent trip, they are ALWAYS told that they are connected to the wireless network with limited connectivity.
Going to Device Manager, uninstalling the wireless adapter (disabling doesn't work) and searching for changes doesn't produce a result either.
Because the wireless network was showing as PUBLIC each time (and greyed out in the Network and Sharing Center so that it couldn't be changed), I went into gpedit.msc and changed the settings to allow for the user to adjust the connection type (home/ work/ public). Reconnecting then connected as a Work network (what we wanted), but still with limited connectivity.
The only result which has given us some connection is uninstalling device from device manager, then downloading and installing driver from Dell. However, as this client has an Ethernet-to-USB adapter which came with the machine, every time we connect this in, disconnect the wireless network, then reconnect the network, we are back to square one where all the tried methods of connection above fail. As the user used both connection methods prior to his trip, I'd love to know how we can get things back to normal again.
I will run a malware/ virus check with the clients ESET Smart Security, but trust that it won't find anything as it's a pretty amazing product (from years of experience), though I know there's no such thing as a perfect antivirus.
Look forward to hearing your thoughts...
