Symptom(s):
User concern over the following, or similar observed roaming behaviors:
- Initial connection is not always to closest access point (AP) or broadband wireless router.
- Roaming is not always to an AP/router with a greater indicated signal strength.
- Roaming is not always to the closest AP/router.
- Roaming is not immediate.
Solution:
If your wireless network has multiple APs/routers, the client adapter can roam (automatically select and switch to another AP/router) from one AP/router to another.
The roaming is based on signal quality, rather than distance to an AP/router. Changes in the signal quality are monitored by the adapter to determine whether a roam should occur. However, should the signal quality to an AP/router that is further away remain good the client may not roam to a nearer AP/router, or may not roam immediately.
Most often this behavior is normal and to be expected. The roaming behavior is designed to increase the efficiency of the wireless LAN by minimizing unnecessary data traffic. The behavior also aids in conserving battery power consumption.
