I've never installed OpenWRT and I'm looking for a wifi router with the following requirements:
Must be fully supported by the current release (OpenWrt 23.05.5)
Must support 2.4GHz (there is 5GHz signal interference in my area)
Must support Guest Wi-Fi using LuCI (I assume this is a given for the latest OpenWRT release, but just want to make sure)
Should have easy install/upgrade process (I'm proficient with Linux but do not want to invest too much time/effort to get a working router)
Should have decent range through walls
Shouldn't be too expensive, preferably < $120
Does not need high bandwidth (my internet plan is only 48/48 Mbps)
Does not need to support a VPN
This will be a home office router supporting around 1-3 connected devices at once
I've spent a few hours browsing the table of hardware and researching different options, but I'm having difficult finding anything that meets all these requirements. I haven't found an inexpensive router that appears to be fully supported with an easy installation process, which isn't a pocket-size or travel router (I assume these would have poor range and ability to penetrate walls).
Really? Almost any router that is currently supported can handle all of your requirements. This includes many devices that are a bit older but still fully supported - such devices can be found on the used market for pretty cheap.
Sorry if this is a dumb question (I know nothing about routers), but can this router be used as a stand-alone router that plugs into a modem. It's not just an access point? I'm just surprised because it doesn't have any visible antennae, so I assume it wouldn't have very impressive range or ability to penetrate walls. Am I mistaken?
I think I've been dismissing the ones without visible antennae, e.g. this one, because I assume they won't have very good range or penetration through walls. Am I mistaken about this?
Yes. But to be clear, a well designed AP is still subject to physics. Penetration through walls will always result in lower signal quality, but the extent to which that degrades depends on the materials of the walls, number of walls, and distances involved.
APs running openwrt can be used as routers. If the device only has lan ports per the label on the enclosure, you may need to reassign a port to the wan interface. This is a simple configuration change.
@psherman and @frollic Thank you both for the help! I will likely go with the DL-WRX36. I had previously dismissed it due to two misunderstandings: (1) I thought it might be an access point that would require a separate router and (2) I thought that external antennae were an important requirement. Thanks for clearing up my confusion!
To clarify, would you recommend a wifi router for the main office, plus an AP as a range extender in the other part of the house, as opposed to a wired router + two wireless APs?
Would it be a bad idea to get one of the NanoPi or GL.iNET devices to serve as a wired router, and then hook up two wifi APs in serial? I'm attracted to the easy install instructions for the NanoPi and GL.iNet devices, since it looks like they already support OpenWRT so it's just a one-step upgrade to the latest release?
That is a budget choice, AX router with handful of ports is perfectly within your reach, say if you have network switch already, yes, buy a separate router (also look at mikrotik or teltonika for more industrial style builds) and add simple access points.
