Identify the supported bands
Wi-Fi products can support different combinations of 2.4, 5 and 6 GHz bands. Google’s model guidance, for example, distinguishes Google Wifi/Nest Wifi from Nest Wifi Pro’s additional 6 GHz capability. That is a concrete reminder to check the exact router and receiving device. A network name containing a number is not itself proof of the frequency or generation actually used by the connection.
Keep band and generation distinct
A frequency band, a Wi-Fi generation name and an advertised maximum rate are different labels. Do not infer that every product with the same generation badge exposes the same bands or that a client can join every band transmitted by a new router. Read both endpoint specifications. Regulatory availability also depends on location, so a foreign product description is not a substitute for the intended market’s supported configuration.
Compare at the real viewing position
The useful question concerns the connection where the television or box is used. A fast result next to the router does not describe a different room or an obstructed cabinet. If a product offers a documented way to compare bands, change only that variable and retain the same device and task. Note the selected connection rather than assuming a successful join establishes sustained media performance.
Avoid a one-number purchase decision
Before replacing a router or player, identify the existing equipment, supported bands and actual problem. More bands can offer options but cannot guarantee that a remote service, application or decoder will work. Keep household network observations separate from service-account issues.

Questions, answered
Will a 6 GHz router make every television use 6 GHz?
The television or attached player must support the band too, within the intended regional configuration. Check both endpoints rather than inferring support from the router alone.
