Issue
A Windows-based laptop fails to display any Xavier wireless networks as being available while in the HUB or certain residence halls. However, these networks display as available when the same laptop is used in other locations on campus.
Cause
The HUB and certain other buildings were upgraded in Summer 2019 to the very latest Cisco wireless technologies. As a result, laptops with Intel-based wireless cards may be unable to properly detect access points if their drivers are outdated.
If your laptop does not have an Intel-branded wireless adapter, then this is unlikely the cause of your issue. You can verify whether the brand of your wireless card by checking its name listed in Device Manger under Network Adapters.
Resolution
To resolve this issue, try to update your Intel wireless card drivers from your manufacturer's support site:
In rare cases, we have found that the laptop manufacturer issues newer drivers than what Intel offers. If the Intel driver update does not find newer drivers available, check your manufacturer's support website to see if a newer driver has been issued there.
