  "★ The big advance in Wi-Fi 6 was efficiently transmitting to a large number of users at the same time (but only for new Wi-Fi 6 clients, not prior wifi generation clients).
  
  "The bottom line is until Wi-Fi 6 / 802.11ax clients reach critical mass, the benefits of 11ax are minimal and will have low impact." [Cisco] The key reason why: Wi-Fi 6 was designed from the ground up to provide speed improvements (HE: High Efficiency) to a group of Wi-Fi 6 clients as a whole, NOT an individual Wi-Fi 6 client!
  
  Wi-Fi 6: The sixth generation of wifi is 802.11ax (2019). It provides a maximum PHY speed of 4.8 Gbps on an 80 MHz channel using 8×8 MIMO. The 802.11ax modulation (OFDMA) is NOT backward compatible with any prior version of Wi-Fi -- so you need Wi-Fi 6 clients to take advantage of Wi-Fi 6 router features. However, any Wi-Fi 6 router will be able to revert back to Wi-Fi 4/5 to support your older devices (with NO speed advantage over Wi-Fi 5). "

  "Be critical (and smart): There is no point in replacing your router if PHY speeds to your wireless devices do NOT improve (by at least some reasonable amount). So, be very critical. Take note of client PHY speeds before and after a router update. If you see an improvement in PHY speeds you wanted, great, job accomplished! However, if not, then you have to ask the serious question: Did you just spend a bunch of money and not get the benefit/improvement you needed/wanted? When updating a router, verify that client PHY speeds actually increase!

  A Wi-Fi 6 Recommendation: Virtually all wifi devices (laptops / tablets / smartphones / smart tv's / etc) today are STILL only 2x2 MIMO (at best; some are even still at 1×1). And THAT limits the speed at which those devices will connect to any AP/router (not the max speed of the router). Because of this, get a router/AP with a mininum of: Netgear RAX50 4x4 802.11ax Wi-Fi 6 Router

  A mid-range Wi-Fi 6 router - this is the best VALUE you can get today (July 2022)
  4×4 MIMO - increases signal reliability for all 2×2 MIMO devices, and ensures faster speeds for the rare 4×4 clients.
  802.11ac beamforming - improves signal strength, which increases the range at which devices stay at fast speeds.
  DFS channels - you need a router that supports ALL 5 GHz DFS channels, to increase the liklihood of NOT sharing a channel (and therefore bandwidth) with a neighbor.
  AP mode - look for a router that also has an 'access point mode' (most medium to high end routers will). Because when you do upgrade to a newer version of Wi-Fi, you want to reuse the old router as an 'AP' in your new network (and not have it sit on a shelf unused).
  Wi-Fi Certified - not absolutely required, but if the router is certified, this guarantees "interoperability, security, and reliability." Product Search. Also, watch out for routers certified to a lower specification than expected (eg: a 802.11ax router certified for only 802.11ac).

  An example recommendation: The Netgear RAX50 is a mid-range Wi-Fi 6 highly-rated AP/router for around $212, with 4×4 MIMO for 5 GHz (2×2 MIMO for 2.4 GHz) supporting all DFS channels and HE160 (160 MHz channels) -- so a GREAT VALUE.

  Why just a 'mid-range' Wi-Fi 6 recommendation? I find it incredibly hard to justify a very expensive Wi-Fi 6 router for $600 that only increases speeds for a couple of clients clients, and provides NO speed improvement whatsoever for all other clients in the house -- especially when the next generation Wi-Fi 6E is just starting to come out, which will (yet again!) require new hardware (both routers and client devices).

  Ha nincs bajod a nettel akkor megvarnam a 6E-t.
