Worse still, Wi-Fi *7* devices are already out. Qualcomm's QCN9274's running on the "ath12k" chipset [1] have been a tempting DIY option. Though that module requires an external 3 amps at 5 Volt (15 watts!) to be soldered to it to operate
Decent but sort of annoying to set up;
https://openwrt.org/docs/guide-user/network/wifi/wifiextende... appears to have combined what used to be 2 pages with different instructions, but it still seems to have both sets of slightly different steps. IMHO there really should be a single button in LuCI to make the box just an AP without DHCP/DNS/firewall.
That's my preference as well. Keep the router simple, don't put a transmitter near the sensitive bits to cause interference with the CPU, ethernet, or USB bits. I want my AP to be dumb and do nothing besides connect ethernet to wifi clients. That way when you need more coverage you add APs, newer WIFI upgrade only the APs, etc.
- Switches frequently offer PoE by default whereas routers (especially consumer or PC-grade stuff) would need a PoE adapter
- Devices connected to the switch can communicate directly without the router, saving a hop
- Modern switches may only need to read the first few bytes of the frame before cutting the packet over to the appropriate port, whereas routers tend to need to read the whole packet and apply rules/policy, incurring higher processing costs
An ordinary home LAN may not find any noticeable benefits, but an enterprise setup might benefit.
With separate items, one can put the router somewhere that a router makes sense for routing's sake, and the access points where they make sense for wifi's sake.
My router is on a shelf in my unfinished basement, along with the cable modem and a switch, not far from the other household infrastructure. It's a great place for a bunch of cabling (nobody will ever see it unless I deliberately show it to them) and it is trivial to get more wires to that location.
But the basement is a terrible place for a wifi access point, being underground and all.
So for wifi, I've got a fairly unobtrusive access point (a Mikrotik wAP AC) mounted on a central wall on the first floor, with PoE. Unlike the way that home routers are normally used, this access point only has one wire connected to it, and all it will ever need is exactly one wire.
And if I ever want to upgrade that central switch (maybe I grow some plans for some serious NAS usage or something and 10GbE starts making sense), I just... upgrade it. The router stays the same, the wifi stays the same.
If I ever want to make Wifi faster, or add more of it, I just upgrade that part.
All of these components (router, switch, access point) are necessary for the way we commonly use our home networks in 2024. It's nice having things located where they're most useful, and it is also nice being to change individual parts of the system when that is useful.
> Am I the only one who doesn’t even want their router to have wifi?
I'd prefer to separate the two as well, but I'd rather not admin them separately. It'd be convenient to manage them all in one (fully local, non-cloud) place.
But yeah, my ideal setup would be a 10Gbps Ethernet router the upstream Internet connection, firewall, NAT, and LAN DHCP, and then one or more separate Wifi 7 routers whose only job is to bridge transparently to Ethernet but not handle DHCP or NAT.
I used to think that way, but now my router is a Ryzen 5700G running NixOS so there is no reason to not hang some wifi radios off of it. Additional APs are low power amd64 motherboards (which also run Kodi to drive "TVs"), because I got tired of the ARM dumpster fire. Although I just ordered a pile of RPis to make security cameras, so maybe I'm back looking for a little punishment.
Not required, but you can solder a Multi Link Operation wire between multiple cards (within a single system), to enable them to work in concert together (basically as a 4x4 or whatnot). In case you still really miss soldering extra shit onto your cards!!
