Can we use the UTP Cat 6 wire for Wi-Fi 7 to carry 2.5gb speed?

Yes, you can use UTP Cat 6 cable for Wi-Fi 7 if your goal is to support 2.5 Gbps wired backhaul or uplink/downlink speed — but with some caveats:

Cat 6 for 2.5 Gbps: YES, but...

• UTP Cat 6 is rated for up to 10 Gbps at 55 meters (180 feet).
   
• For 2.5 Gbps, Cat 6 is more than sufficient — it can easily handle:
   
  • 2.5GBASE-T (2.5 Gigabit Ethernet)
     
  • 5GBASE-T (in shorter runs, usually under 55m)
     
  • PoE++ (Power over Ethernet), if powering the Wi-Fi 7 access point.
     

Distance Consideration

Wi-Fi 7 Context

Wi-Fi 7 supports:

• Theoretical wireless speeds over 30 Gbps
   
• In practice, wired backhaul is critical to reduce bottlenecks
   
• 2.5 Gbps Ethernet is becoming a standard minimum for Wi-Fi 7 access points
   

So, using Cat 6 UTP cabling to connect a Wi-Fi 7 router or AP to your network switch is completely viable for 2.5 Gbps speeds.
