Make Devices Roam Faster
You are on a video call, you walk from the living room to the kitchen, and the call freezes — even though both rooms have Wi-Fi. The problem is roaming: your phone clings to the far access point instead of switching to the near one. The 802.11r fast-roaming standard speeds up that handoff. Most modern mesh systems support it, but it is often buried in advanced settings. If your whole network is one weak router, check whether an access point upgrade makes more sense first.
TL;DR / Quick Fix
Quick fix: if calls drop when you walk between rooms, turn on fast roaming (802.11r, often with 802.11k/v) in your mesh or access-point settings. Keep one network name everywhere and make sure coverage overlaps. Update firmware, then test with a real walk while on a call.
Follow these steps
- Understand what 802.11r does. Normally your device fully re-authenticates each time it switches access points, which takes long enough to drop a call. 802.11r pre-authenticates with nearby access points, so the handoff happens in milliseconds.
- Check your access points support it. Look in the router or mesh app's advanced Wi-Fi settings for 'fast roaming', '802.11r', or 'FT'. Most mesh systems from the last few years include it; a single old router cannot roam to anything.
- Turn on the roaming helpers together. Enable 802.11r along with 802.11k and 802.11v if offered — k helps the device see neighboring access points, v suggests the best one to join. They work as a team.
- Use one network name everywhere. All access points should broadcast the same SSID and password. Different names force your device to treat them as separate networks, which defeats roaming entirely.
- Fix placement and power, not just settings. Overlapping coverage matters more than any toggle: place access points so their signals overlap by roughly a third, and avoid cranking transmit power to maximum, which makes devices cling to the far point. Band steering settings can help push devices to 5 GHz for cleaner handoffs.
- Test with a real walk. Start a call and walk your usual path. If the handoff still stutters, update the access-point firmware — roaming bugs are a classic firmware fix — before buying new gear.
What NOT to do
- Do not enable 802.11r and expect miracles on a single router. Roaming needs multiple access points; one router has nothing to roam to.
- Do not use different network names per room. Split SSIDs break roaming by design — unify them first.
- Do not max out transmit power on every access point. Overlapping signals at full blast make devices hold onto the wrong one longer.
- Do not forget some old devices dislike fast roaming. If one gadget drops after enabling it, check for a per-device or per-SSID exception.
Frequently asked questions
Will 802.11r fix dead zones?
No — it speeds up switching between access points that already cover an area. A dead zone needs another access point or better placement, not faster handoffs.
Do my devices need to support it?
Most modern phones and laptops do. Very old devices may ignore it and roam the slow way, or in rare cases misbehave — firmware updates usually fix that.
Is fast roaming the same as mesh?
No. Mesh is the system of cooperating access points; 802.11r is the standard that makes handoffs between them fast. Good mesh systems use both.
