Hello Tom,
It sounds like the problem may be with the eduroam profile, certificate, or your university account rather than the Wi-Fi adapter itself.
Using another internet connection or a mobile hotspot, download your institution’s official eduroam installer through the eduroam Configuration Assistant Tool. Select your university and run its installer. This installs the authentication settings and certificates required by that institution. Avoid accepting or installing certificates from unofficial sources.

When signing in, enter the full username format required by your university, often including the domain after the @ symbol. If you recently changed your university password, check whether eduroam requires a separate Wi-Fi password or access token.
You can also try the additional troubleshooting methods shared in this solved Microsoft Q&A case. Please note that eduroam settings vary by institution, so only use the certificate and authentication settings confirmed by your university’s IT department.
Note: Although the referenced case uses the tr-TR (Turkish) locale, both the question and answer are written in English.
If the issue continues, please contact your university IT helpdesk. Ask them to confirm that your account is enabled for eduroam and that its certificate or network-access token has not expired.
