If users are experiencing intermittent wireless connectivity, the best initial step is to check for sources of interference. Wireless signals can be disrupted by a variety of factors, such as other wireless devices, cordless phones, microwaves, or even large metal objects and walls. Addressing interference often resolves the intermittent connectivity issue. Updating the device drivers could resolve issues related to the hardware functioning improperly, but is less likely to be a cause of intermittent signal loss or impact many users at once. Checking for IP address conflicts is a possible step if network devices are having connectivity issues, but this doesn't typically cause an intermittent drop in signal. Lastly, enabling QoS settings on the router can improve the quality of service for certain applications but would not resolve the fundamental issue of signal loss.
