Can't connect to wifi (Eduroam) with RTL8187SE

Solution 1:

Whether the IT staff can see connection attempts depends entirely on where they're looking. Modern Wi-Fi networks are centrally managed, and failed associations usually don't get sent to the controllers at all, they're only seen in the AP logs.

The dmesg log shows the system's trying to associate with multiple APs, but the associations are rejected with reason code 10. This translates to AP not being able to support the capabilities the client's requesting. Other mentioned reason code is 18, which means the AP can't support the requested data rates. The client's Realtek RTL8187SE, which is a 2.4GHz b/g device that can support max 54Mb/s data rates.

It may be that the network doesn't support 2.4GHz at all. If it does, low data rates are probably disabled (a common technique to prevent stuck client -issue in 2.4GHz networks). If only the 54Mb/s data rate is allowed, older clients can easily have this kind of problems. Due to interference, distance or any of the other myriad 2.4GHz issues the client might not be able to request full speed connection. Enabling data rates down to 36Mb/s could resolve the situation.

The only other option I can really see is getting a new USB Wi-Fi adapter that supports ac-standard, if not current ones.
