WAP4410N - mode bgn, Data rate with mixed g & n clients

[Regs]

Does the data rate to N connected clients go down to G rate if there is even a single G client connected?

Hello James,

Thank you for writing. The relationship between modes and effective client data rates breaks down as follows:

• B, G, or N Only: The WAP only accepts clients for the particular mode defined. Clients will operate at up to the defined data rate (11 Mbps for B, 54 Mbps for G, and up to 300 Mbps for N).

• B/G Mixed: The WAP will accecpt both B and G clients at their respective data rates. N clients will netotiate at the G data rate.

• B/G/N Mixed: The WAP will connect all clients at their respective data rates. B clients will negotiate at only up to 11 Mbps. N clients can netogiate at up to a theoretical 300 Mbps. The WAP will accept multiple modes simulationoulsy. However, your effective data rate will only be as fast as the slowest mode connected. Therefore, connecting a B device will lower your overall data rate.

Hi, My name is Eric Moyers. I am a Network Support Engineer in the Cisco Small Business Support Center. Thank you for using the Cisco Community Post Forums.

Let me clarify one thing that my colleague mentioned above. During B/G/N mixed mode, if you have 3 devices connected at N and a G device then connects. The N speeds will start negotiating at G speeds. As well, if you then have a B device connect, the G and N devices will start negotiating at B speeds.

Your data rate will only be as fast as your slowest device.

Thanks
