Araknis Networks Wireless Access Point
Product Manual
Wireless Settings
15.3.1 - Fast Roaming Mode
This powerful feature, known in Araknis products as Fast Roaming, is essential for building reliable WiFi
networks with multiple access points. After a client joins a WiFi network, they don’t always stay close
to the WAP they originally connected to.
Without Fast Roaming, the client will remain connected to one WAP until signal is lost, then find a new
connection. Fast Roaming tells the client when to move the connection, then makes the switch with
minimal delay. This keeps clients on the fastest and most reliable WAP at all times.
Special Setup Requirements
• Two or more WAPs, all with wired LAN connections
• All WAPs set to Access Point operating mode with Fast Roaming enabled
• Same SSID configuration on each WAP
Installation Notes
• WEP security mode does NOT work with Fast Roaming.
Configure SSIDs using other encryption modes.
• How do I configure the locations of WAPs for the best performance?
Use a site analyzer tool to determine ideal WAP locations. For the best performance, use more
WAPs closer together and reduce the transmit power some to avoid interference (Advanced
Wireless Settings).
• Does it matter what operating channel is used?
If you aren’t using Auto Operating Channel selection, use a different wireless radio channel in each
WAP to lower the amount of interference each device encounters.
• Do fast roaming and band steering work together?
Yes, configure each one based on individual needs. Remember, some devices may not be compatible
with these features.
• How do I set up Guest Networks with Fast Roaming enabled?
The guest network feature is not ideal for use with Fast Roaming since each WAP creates a new
DHCP server for clients connected to that SSID. Instead, create a separate VLAN and assign SSIDs
for guest use. See section “24.1 - Configuring Guest Networks with Fast Roaming” on page 79
for setup instructions.
• Is this a proprietary technology for Araknis Networks?
No. Fast Roaming utilizes the standard IEEE 802.11r and 802.11k to negotiate handoff with the client.
Only clients that support 802.11r/k are able to perform best in this environment.
• Do any other WAP brands that support Handoff work with Araknis Fast Roaming?
We don’t guarantee compatibility with any other brands, but will list them if we find any that are.
• Does any equipment NOT work with Fast Roaming/Handoff?
• Gen 1 Apple iOS products won’t work. Most newer iOS devices work correctly.
