Gaming PC with GALLERIA, Radeon RX 6950/6750/6650 XTThe same goes for telephone lines, TV antennas, and CATV cables.Since the Heisei era, the Internet and Wi-Fi environment have been added to it.It can be said that many IT devices no longer support wired LAN, and Wi-Fi maintenance has become essential even in ordinary households.As for Wi-Fi, Wi-fi 6 is hot right now.Wi-Fi 6 compatible devices are available for each company's products, and most of the new products released in the future will be Wi-Fi 6 compatible.Radio waves are a finite resource, so if they are not used efficiently, they will fail.Don't forget the past catastrophes of 802.11n access points and the unreliability of Wi-fi in the city.However, even if you make the Wi-Fi environment in your house compatible with Wi-Fi 6, you cannot make full use of that environment unless your device supports it.No matter how good Wi-Fi 6 is, it's not practical to replace every device in your home with one that supports Wi-Fi 6 at once.Even with WPA, it is difficult to change from 2 to 3, but even with AX support, each device hanging from the access point needs to be replaced with a compatible device in sequence for each life cycle.Considering the replacement cycle of various devices, the mixed environment must continue for at least five years.I checked the DHCP lease status of my Wi-Fi router.DHCP is a mechanism that assigns a unique IP address to each device hanging from a router, etc. As a result, terminals are hung there by wire or wirelessly as many as the number of assigned addresses.We were assigned a total of 34 IP addresses.Combined with smartphones, PCs, smart speakers, VCRs, etc., this number of devices are always in operation.I tried the Wi-Fi 6 compatible LINKSYS "Velop AX Series MX5300 Mesh Wi-Fi 6 Router".It's one of the products that anyone can easily set up their Wi-Fi 6 infrastructure.However, Velop is a product that is premised on connecting to the IPv6 Internet by wire.The WAN side needs to be the Internet.There is no ability to connect to the provider and establish an internet connection on your own.In Japanese infrastructure, except for the shared Internet and CATV Internet in apartment buildings, in many cases, another negotiation is required to connect to the Internet.After contracting with a provider and connecting to physical devices, you will be required to connect to the Internet via OverEthrenet.That is the connection procedure such as PPPoE and IPoE.Even if an optical line is laid to the room, another device such as an optical modem (ONU) is required to convert the light to Ethrenet, and a terminal and a terminal can be used to connect to the Internet using that Ethrenet. The router needs a connection function for that purpose.All-in-one devices that connect to the Internet via Wi-Fi by plugging in the optical cable that comes out of the wall can only be found in special products such as Hikari Denwa compatible routers and home gateways that are rented by operators under a line contract.And these devices don't currently support Wi-Fi 6.The truth is, I want you to manage this complicated situation.It is desirable that you can connect to the Internet with IPv6 just by attaching an optical cable from the wall, and you can create a Wi-Fi 6 environment with a gentle operation like Velop.In the worst case, you will need three types of devices: optical modem (ONU) → connection router → Wi-Fi router, so you can't feel free to work on improving the environment.Wi-Fi 6 compatible mesh Wi-Fi router, "Linksys Velop AX MX5300" that can be used alone with a tri-bandAnker Soundcore Life P3 (Wireless Earphone Bluetooth 5.0) [Complete wireless earphone / Bluetooth 5.0 compatible / Wireless charging compatible / Ultra noise canceling / External sound capture / IPX5 waterproof standard / Up to 35 hours music playback / Gaming mode / Dedicated application compatible / Call noise reduction / PSE technical standard conformity] BlackSony wireless noise canceling earphone WF-1000XM4: Completely wireless / Amazon Alexa installed / Bluetooth / LDAC compatible / High resolution equivalent up to 8 hours continuous playback / High precision call quality / IPX4 drip-proof performance / Wireless charging compatible / 2021 model / with microphone 360 Reality Audio Certified Model Black WF-1000XM4 BMSony Wireless Noise Canceling Stereo Headphones WH-1000XM5: Improved Neucan Performance / Improved Call Performance / High Sound Insulation with Soft Fit Leather / Black WH1000XM5 BMOnly now is super profitable!
