    Hi Team,
    I have a fairly new Dell XPS 13 9360, running Windows 10.
    It has recently stopped picking up the Wifi network at my office, but has no problems at home or with any other network (mobile hotspot works fine too).
    All other devices at work can connect to the wifi and there have been no changes made to the router/modem settings that we are aware of.
    Its a small business so we don't have an IT support and we have exhausted our limited knowledge.
    So far we have tried:

    creating a new network,
    re-installing windows,
    DNS flush,

    The router runs all of our cash tills and stock database, so I'm a bit anxious about poking around in the settings.

    Any help would be greatly appreciated.

    What channel is the router using now? If it is set to "auto" it may have changed to 12 or 13 recently.

    What channels does your wireless adapter support? My educated guess is that is supports channels 1 - 11.

    Of course, my post is nonsense if you are using 5 GHz.

    Check to see if you've set the Wifi to operate on a single band. Either 2.4Ghz or 5Ghz. It may be that your office has only one of those active? It should be under the Advanced settings for the Wifi card. Also check to see if a specific channel is in use.

    Edit: Terry beat me with his reply. But essentially it's the same thing.
