Needs more specifics on what kind of issues they are having. A question with this few specifics is difficult to answer. Does your network have a WPA key? Are you broadcasting on both 2.4 GHz or only 5 GHz (Google devices tend to "like" sticking to the 2.4 side, in contrast with apple which prefers the 5 GHz, so turning off either side can have problems). What's your authentication setup? This link Fix Internet connection issues - Chromebook Help would tend to indicate that the Chromebook is somewhat limited as to how it can authenticate, specifically:
Your Chrome device can connect to the following types of Wi-Fi networks:
- Standards: 802.11 a/b/g/n
- Security: WPA/WPA-2, WEP, EAP-TLS, EAP-TTLS, EAP-PEAP, and TKIP. We recommend WPA-2.
So if you have a different, arguably more complex, authentication setup, the Chromebook and some other devices may simply not be able to understand your network.
