Hi,

TP-Link does not offer the channels that require support for DFS (Dynamic Frequency Selection) on their lower-priced router models like the Archer C64. These routers are limited to non-DFS channels, which for the "EU" models are channels 36 to 48 and for "US" models are channels 36 to 48 and 149 to 165.

I am not familar with every router model TP-Link makes, but the lowest-cost model I am aware of that supports the DFS channels (52 to 64 and 100 to 144) is the Archer AX53.
