I have many nerdy friends who have been Linux users for ages. But most of them don't know such a thing as Openwrt exists or have never bothered to give it a try.
It's a very fun piece of software to play with and can be extremely useful for routing traffic.
Wondering why it isn't more popular/widely used.
I was actually the lead engineer on an Openwrt router. I hadn't heard of it before that, but at one point I pretty much knew it inside and out. It's been a few years since I left that company, so I'm a bit rusty at this point.
We made tons of custom features for our router. I did the backend and implemented UIs for most of them. The biggest feature I did though was a full REST API to be able to configure the router from a smart home controller, which was the company's main product. I did both the router side (server) and the smart home controller side (client/caller), including the UI on the smart home controller. I spent almost a year on just that feature. But I was damn proud of it by the end.
Past Linux user here, not only do I use openwrt, but I base my routers choice on openwrt support, it's weird to me there are long term Linux users who don't know what openwrt is
I've been using it for years and now I basically can't live without it. I consider OpenWrt compatibility in all of my router purchases. Currently using a Netgear R7800 and a Belkin RT3200, both are going strong.
It isn't as widely used because it can be finicky to flash sometimes, and that's if it's even compatible in the first place. Even if it works, you may experience a drop in performance unless OpenWrt supports using the routers hardware acceleration features. If there's no support, OpenWrt basically uses the onboard CPU to do routing and they're usually not all that powerful.
Fine on limited hardware like a router but if you're going to use a full box for your router (or a VM), you'd probably want OPNsense for the ease of management and the fact that it's targetted for hardware like that.
I've used OpenWrt, DD-WRT, and Tomato firmware on the various routers I've had. I don't think I've ever kept the stock firmware on any router I've owned.
I use pfSense at home now, but I've been considering switching to OPNsense. I still run OpenWrt on a portable router that I use when I'm traveling though. I won't ever buy a router that I can't run open source firmware on.
Installed OpenWRT on my NetGear router like 2 years back, and it didn't give me any trouble since then.
BTW, the amount of configuration options it offer is mindbogglingly.
I actually took some older now somewhat defunct google wifi pucks and got them all set up on openwrt not too long ago. Really enjoy having them on something with a dedicated web UI and perfectly nerdy
I use OpenWRT on my Linksys WRT3200ACM because I used to have a cable connection that suffered from bufferbloat. The SQM feature made a huge improvement. I eventually switched to a fiber connection from a different ISP which does not suffer from bufferbloat, but I kept OpenWRT on my router.
I do know about it, but I don't even have internet at home.
Though I do use DD-WRT on my WRT160NL which I use at school. For me it acts as firewall + setup-free VPN + DNS Ad blocker (NextDNS). I also have separate passwordless guest network on it if someone wants to use my router. Separate subnet, unbridged with net isolation and AP isolation enabled. And also QoS set to "Bulk" while my network is set to "Maximum". And also forced DNS redirection enabled, so that everyone who doesn't use DoT or DoH uses NextDNS.
In my experience it's because it's finicky as fuck and requires very specific (and often more expensive) router models, and even then it still crashes just as much as a proprietary os router.
About a million years ago, back in 2007/2008 that is, there was this small company called Hexago that did R&D in IPv6 networking, they were behind the Frenet6 project and created the networking stack and the TSP client that would let you tunnel a /56 IPv6 network over a dynamic IPv4 connection.
One the projects was a tiny hardware router, I honestly forget who made it, but Hexago would buy them, then we would flash each one with WRT+TSP client custom image, the idea was you plug this in your network and you have IPv6 connection in your network without doing any magic configuration.
It worked well until we lost finding.
So yeah, OpenWRT is old and not just for Linksys routers :)
I've known about it for years, but my router is loaned from the ISP so I can't install any custom OS on it (although I've considered buying my own for a while because I can't even do proper DNS for my internal network on it). A while back I used to have a router, but the default OS was enough for my needs so I also never considered installing anything different.
I mean, what does one have to do to replace an ISP owned router and what are the benefits? How much does one have to know in order to setup a connection? How does one get connection details from the ISP owned router? How much does a replacement router cost?
My ISP owned router allows me to configure NAT forwarding, replace the DNS, setup a DMZ, assign static IPs to MACs, turn off the internet at specific times (e.g at night), configure parental controls (allows websites, internet access) per device, and probably a few other things I haven't discovered yet.
As a seven-plus year Linux vet I've known about OpenWRT for some time but only made the switch about 3 months or so myself to breathe some life into an aging Linksys.
I'm very impressed with the kit so far, it runs well (snappy even) and the amount of options provided are a bit overwhelming at first. Eventually I'll move on to prosumer hardware, but this is a nice middle ground in the interim.
I used dd-wrt for a few years, but I realized I didn't need it as my new router have the functionality I want. I also realized my router had much better throughput with the stock firmware.
Nowadays, I bought a mid price router from a well known brand, and seriously: The router works, has all features I need (even WireGuard OOTB) and for now I see no reason to replace the provided firmware with OpenWRT. YOLO!
Yeah of course! Once I went on a buying spree of used WNDR3700. They were so cheap and I won a few too many bids at once.
I gave one to a flatmate when we lived together as students and he took it with when he moved out. Put one in the office room of my current flatmate and still have one or two in reserve. I usually take one with me to LAN-parties.
Before that I once used DD-WRT on a WRT54GL. It also wasn't bad from what I remember.
I personally use it on a protectli with the 2.5G ports. I also replaced my ISP modern with a protectli running OpnSense. Decided to opt into that as my solution to have two different softwares protecting my network and also so I could scope internet facing devices at the OpnSense level instead of internal to the network. Just in case they get compromised, they can't access the rest of the network. Call me paranoid... But I also find it much easier to manage lol.
Years ago I derived a flash with vtun on it. It's so old, now, but vtun still goes and connects. And since it's not systemd, it'll keep hammering at the connection until it succeeds.
So these old routers are still out there, and when a soho site is sick and we can't get in we instruct someone to plug in the blue box and it calls out for help.
It's so ghetto but, in places like the southern states where rural power outages can outlast generator time, it has cut down our time to recovery tremendously.
I know about it, but I prefer Asuswrt Merlin firmware for my routers, because I mainly use ASUS routers (powerful, modern (WiFi 6E etc) , easy to find second-hand models for cheap) and Merlin firmware is very well integrated with the routers and uses the same UI as the stock firmware, but provides additional features like a package manger etc.
In fact I believe ASUS themselves have started to use some of Merlin's patches in their firmware, which goes to show how professional Merlin is.
OpenWrt was relatively popular back in the day when Linksys routers could run Linux. At some point iirc Linksys sadly replaced the default Linux based firmware by a closed source OS, and also decreased the amount of memory for the firmware. A few years ago I saw that there was an option to install OpenWrt in an lxc container, I briefly played with it, nice nostalgia.
I am aware of openwrt and used to use when I used router hardware. I have moved to pfsense. I install it on either a 1 liter mini PC or some other older enterprise piece of hardware.
I've long known about it. I don't seriously use it, but I would if only my Wi-Fi router was fully supported. It's an Asus one (that I got for free from T-Mobile a decade ago) so I installed Asuswrt-Merlin on it instead.
Following the recommendation of homelab communities, I got into OpnSense (a BSD-based firewall system for x86 hardware only) last year, still keeping my Wi-Fi router as a dedicated AP. In hindsight I somewhat regret that choice and probably would've been better off buying a new OpenWRT-compatible router and using it to handle firewall/routing/AP all in one device instead of wasting the power draw of another separate N100 system. I like having wireguard and vnstat in my router now, which Merlin didn't offer, but I know OpenWRT has those too and I don't have any other needs that warrant a higher-power router.
I used it before, but ultimately it comes down to compatibility. Broadcomm is dominating the router space and 3rd party firmwares are a nono for that. So I just got an Asus that is supposed to be supported for a very long time.
I bought a router with OpenWRT support but the official firmware works well enough and I can't really be bothered to switch it out for OpenWRT right now lol
it's good to know that I can in the future though, that wasn't an option with my last router
I’ve been debating buying a cheap aliexpress mini 2.5G router pc and doing something of the sort. But I have been too lazy to look into if I can still use my orbis as access points. Maybe tonight’s the night.
