What usually goes wrong
A smart plug or camera won't pair until the network names are separated temporarily.
Free things to try, in this order
- 1
Use the app's setting to split the bands briefly, pair the gadget, then merge again.
- 2
Turn off 'fast roaming' only if an old device keeps dropping.
- 3
Place units so each one still gets two solid bars from the next.
Before you buy anything
One extra unit is nearly always cheaper and better than a new system.
