![20. A Reality Check
◆ Wi-Fi will never fully compete with wired Ethernet: Ethernet uses a dedicated full-duplex channel for every device, so each connected device individually obtains the maximum speed this then becomes a potential capacity multiplier. Whereas Wi-Fi uses a shared half-duplex channel, where all devices connected SHARE a single common maximum speed.
◆ You get what you pay for: Most dirt-cheap inexpensive routers and access points <$50 will have performance throughput limitations. Don't expect top level sustained performance like 80% of PHY from an entry level router/AP. So keep this in mind when looking for new equipment. But if you don't need top level performance right next to the router you are OK with only a couple hundred Mbps max, then a cheap router could be a great value, for you.
21. Recommendations
Wi-Fi Certified LogoBe very critical: There is no point in replacing your router/AP if PHY speeds to/from your wireless devices do NOT improve by at least some reasonable amount. So, be very critical. Take note of client PHY speeds [§4] and throughput speed tests [§D] before and after an upgrade. If you see an improvement in 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 device PHY speeds and throughput speed tests actually increase, especially for devices 'at range'.
When buying a new router, what features do you need to best support 1 Gbps throughput wirelessly?](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:sljruhr6rpwu4kqimoqrda3o/bafkreibr7ne4cr7htwrlrkkr6ku2l4hbc44txe5ceakcu3sryx6yq7kqze)
