If the STA roaming speed is slow, how can I handle it

22

The causes and solutions for slow STA roaming speeds are as follows:
1. The roaming sensitivity of STAs is not properly configured on the AC.
Adjust the roaming sensitivity of STAs.
2. The network is not properly planned.
Optimize the network plan.
3. AP signal interference exists.
Scan AP channels to eliminate interference.
4. Users use different security policies. The roaming time of a STA using WEP is smaller than that of a STA using WPA.
Select proper security policies based on actual requirements.
5. STAs switch between different channels during roaming. The roaming time of a STA that switches from channel 1 to channel 6 is smaller than that of the STA that switches from channel 11 to channel 6.

Slow handover may cause packet loss during roaming. It is normal if only 1 to 2 packets are lost in this process.

Why is the channel switching sometimes slow during STA roaming? How can I improve the roaming sensitivity of a wireless NIC
The roaming process takes a long time due to the following reasons: - Users use different security policies. The roaming time of a STA using the WEP security policy is smaller than that of the STA using the WPA security policy. - Users switch between different channels during roaming. The roaming time of a STA that switches from channel 1 to channel 6 is smaller than that of the STA that switches from channel 11 to channel 6. - STA NICs differ. The roaming time is determined by the NIC performance. To configure the roaming sensitivity of a wireless NIC (for example, on a PC running Windows XP), choose Start > Settings > Network Connections. Right-click the wireless NIC, choose Properties, and click the Advanced tab. Adjust Roaming Initiative. If the roaming initiative is adjusted to the lowest level, the roaming sensitivity decreases to the lowest level. If the roaming initiative is adjusted to the highest level, the roaming sensitivity increases to the highest level.

STA receives strong signals from an AP, but the network speed is slow. How can I locate the problem
Locate the problem as follows: 1. Check the number of users associated with the AP. The number of associated users cannot exceed the upper limit allowed by the AP. 2. Check the channel and power of the AP. The channel and power must be set to fixed values, but cannot use default settings. 3. Change the connection mode on the AP to high-speed access. 4. Check whether upstream bandwidth limit is set on the AP. 5. Check antennas on APs: - The interval between the antennas on different APs cannot be smaller than 10 m. - The interval between the antennas on the same AP cannot be smaller than 7 m. 6. Use the dedicated tools to scan adjacent-channel interference. Check whether there is strong interference near the STA.

When a STA is roaming, whether the STA subnet attributes are changed
During STA roaming, STA subnet attributes such as the IP address, VLAN, ACL, and priority are inherited and will not be changed.
