Fast Wi-Fi roaming

A computer system comprising:

• a processor;
• a computer-readable storage medium storing instructions executable by the processor to:
• identify forwarding data associated with a first active session of a first application running on a client device connected to a home access point (AP);
• preemptively provide, from the home AP, the identified forwarding data associated with the first active session to each of a plurality of neighboring APs to which the client device is not roaming and while the client device is connected to the home AP;
• and
• after preemptively providing the identified forwarding data and in response to determining that the client device is roaming to a target of the neighboring APs, provide other forwarding data associated with another application from the home AP to the target AP.

A non-transitory computer-readable storage medium comprising instructions executable to:

• store, in a roaming cache on a target access point (AP), forwarding data from a home AP for a client device connected to the home AP and not connected to the target AP;
• in response to determining that a client device of the plurality of mobile devices is roaming to the target AP, access in the roaming cache on the target AP, the stored forwarding data, including forwarding data associated with a first active session of the client device;
• and
• with the target AP, use the accessed forwarding data to continue the first active session for the client device.
