Can I extend my broadband to the ground floor with a Wi‑Fi 6 mesh?

A 250 Mbps broadband connection is more than enough for 4K streaming; many services use roughly 15–25 Mbps, though extra capacity helps avoid buffering when other devices are active. The important factor is the downstairs connection quality. A wired Ethernet backhaul to the mesh unit will usually be much more reliable than having the mesh node communicate wirelessly through floors and walls. Placement still matters, so test the TV’s actual speed and stability after installation.

Yes, one additional mesh unit can work if it supports access-point or bridge mode. Connect it to the Airtel router with Ethernet and place it on the ground floor. In that setup, the existing router can continue handling the internet connection, while the new unit provides Wi‑Fi downstairs. If you want seamless roaming and centralized management, a proper two-node mesh system is usually cleaner: connect the main mesh node to the router by Ethernet, then place the second node downstairs. You can disable the router’s Wi‑Fi if the mesh will cover the whole house.

Solid copper Ethernet is generally the better choice than CCA. Copper is more flexible, conducts electricity better, handles Power over Ethernet more reliably, and is less likely to crack or fail after repeated bending. CCA cable may work for short, low-power connections, but it’s less durable and may not meet the expected performance of the cable category, so look for cable labeled solid bare copper.
