I'd like to buy a dual-band router as an access point sharing the same SSIDs as a TP-Link Archer C5, but want to make sure that 802.11k/r roaming is available for dynamic rehoming based on the strongest RSSI. Would I be best off buying another C5 and enabling WDS bridging, buying another C5 and switching to DD-WRT firmware, or buying a router known for good 802.11k/r hand-offs?
