Ever walked around your office or home, only to realize your device is still clinging to a weak WiFi signal, even when a stronger AP is nearby?
That’s the Sticky Client Problem—and it’s one of the most frustrating WiFi issues!
Why Does This Happen?
Most WiFi clients don’t roam proactively. Instead, they:
Connect to an AP and stay connected as long as they can.
Only switch when the signal is completely unusable (not necessarily when a stronger one is available).
Use different roaming triggers based on vendor-specific algorithms.
Since roaming decisions are client-driven, two devices in the same spot may behave differently—one switching quickly, while the other clings to a weak AP like its life depends
on it! 
Why Sticky Clients Are a Bigger Problem Than You Think
Sticky clients aren’t just an inconvenience—they can significantly impact network performance, especially in high-density environments:
Slower Speeds for Everyone – A sticky client using low data rates forces the AP to slow down transmissions, affecting all connected devices.
Poor VoIP & Video Calls – Real-time applications suffer due to high packet loss and jitter.
Security Risks – Some devices may reconnect to rogue APs if they fail to roam correctly.
How Can We Fix This?
AP-Side Solutions
802.11k – Helps clients discover better APs faster.
802.11v – Suggests better APs to clients, optimizing handoffs.
802.11r (Fast Roaming) – Reduces reauthentication delay for seamless transitions.
RSSI-based Disconnect – Some APs force clients off when signal drops below a threshold.
Client-Side Fixes
Enable Aggressive Roaming (if available in WiFi settings).
Restart WiFi or toggle airplane mode to force reconnection.
Update device firmware—some vendors improve roaming behavior over time.
Want to See It in Action?
I’ll be sharing Wireshark captures 
showing how clients decide whether to roam or stay stuck on a weak AP! This capture will focus on 802.11k, 802.11v, and 802.11r to analyze roaming behavior.
