| This test verifies that before we finish association and DHCP negotiations, |
| WiFi bitrates remain low. Lower bitrates trade speed for resiliency. In |
| noisy or marginal RF environments, this allows us to finish the time dependent |
| negotiations that establish connectivity without the risk of packet loss. We |
| have seen environments where a dropped DHCP or 4 way WPA handshake packet |
| can cause association to time out. |
