Abstract: Off channel scanning on workgroup bridge (WGB) devices for fast roaming may be provided. First, it may be determined, by a first WGB, that a second WGB is not off-channel. The second WGB may be peered with the first WGB. Next, the first WGB may perform channel scanning in response to determining that the second WGB is not off-channel. The first WGB may then prioritize a first WGB channel list based on results from the channel scanning performed by the first WGB. Next, the first WGB may roam while the second WGB in not off-channel, from a first access point to a second access point on a channel with the highest priority in the first WGB channel list.
