I have two Wi-Fi units that may soon lose firmware update support
  • Netgear: R7000 — Nighthawk AC1900
  • ASUS: RT-AC68R
Just how good is dd-wrt as an option to keep up with security patches, etc? it's been in beta since 2008

I anticipate that Merlin will also drop support.

Right, most users would probably be better off with tomato, which is also excellent

Fortunately it works with both of yours :)

R7000:

RT-AC68R:

I'm 90% certain that fresh and advanced (advanced is just shibby with some bells) will work on the AC-68R (they work with the U version) but you should google I don't want you to brick your router

I have a few older Netgear Atheros based running dd-wrt. I like it it because it has a strong wiki. Anything you need help with will be explained in the wiki, on the chip level. I have even bought the superchannel license to experiment in licenced spectrum, where I have privileges.

I say, read up on flashing procedure for one of the devices and try it.

In general Tomato is for Broadcoms and their SoC has all hw features active and you should use it.

The more popular the device, the more stable it should be. Mileage varies. Considering you have really old device platforms, you have absolutely notning to loose.

But... do you even have the ideas utilise what free router OS gives to you because of fhe questions you have? Not sure.

I say, read up on flashing procedure for one of the devices and try it.

I have tried dd-wrt in the past on a D-Link Dir-601 and was disappointed when it stopped updating properly and I had to go to the D-Link emergency room to achieve each update. I also tried it on an Engenius ECB-3500 but felt the power levels were wrong under dd-wrt; Sebastian Gottschall (BrainSlayer) kindly let me have a license.

I thought the super-channels 12, 13 and 14 were not allowed in the US (fortunately they are not on by default in dd-wrt)

The NETGEAR has a nice unbrick route using TFTP (which I have unfortunately had to use) and I think the ASUS has its own system as I am tired of the JTAG recovery route (the ECB-3500 just stopped booting at some point).

I am not so interested in repeater mode as it halves the bandwidth and prefer to use two units at non-overlapping frequencies back-to-back, one in bridge mode the other AP; this is how I ran a repeater tower I built (with help) some years back using two Cisco Aironet 1300 units. At the time the repeater feature was not even working on the Aironet 1300 as confirmed by one of their engineers.

As stated in the original post, I am after new firmware for the security support should they pull support for the units I presently run. I also have an Apple Airport Extreme and some Securify Almond 3 units, but these are no longer supported and have no alternative firmware.

The Almond 3 had issues with one of its capacitors
Securifi Almond 3 Repair (SMD capacitor) | Electronics Repair And Technology News (jestineyong.com)
but once fixed makes for a really nice weather station.

For now there is Merlin for the RT-AC68R (Home | Asuswrt-Merlin) and there is also a port for the R7000 but it has issues
AsusWRT-Merlin (XWRT/Cross-WRT) for NETGEAR R7000 | MyOpenRouter


802.11ac gives me all the bandwidth I need, so I am not tempted to upgrade and just want something secure and reliable as these units are used for work.

was disappointed

There are some dud devices where simply they do not perform, usually wifi range sucks or something else, like drops and hicckups. I had it with poorer wifi EA6400, like beamforming was doing something else. Because it is whacky Broadcom. I used Tomato once it died on me. I've had a lot of devices and none of them were perfect using DD-WRT. Merilin was usually fine, but still the update cycle lacked and Asus is expensive.

I've got Xiaomi AX3200 for 50$, flashed OpenWRT immediately and I prefer OpenWRT than Tomato or Merlin. Software is pretty stable and you can pick two wifi driver versions. For the price it is hard to top. But it has HW variations now with different complexity to flash a normal OS. It has TFTP recovery also, hard to brick. There are many MT7622B based routers, there is plenty of choice. HW acceleration work on those using OpenWRT.

I have separate small router MTK MT7628 sub network 2.5GHz devices for IoTs and DIY HUE service, but recently I've switched to BPI-R3 as an experiement as my main unit and retired the AX3200 that was just a temporary solution after EA6400 death. Despite being BPI thanks to Mediatek base and shared libraries it currently works without major bugs and that's something unusual. Also considering the price and HW currently nothing can top it. It is just a bit harder to set up and you need to assemble it, but it gives you so many choices. It updates daily from the main branch. The forum is also supportive and git maintainer is active. I can get ~2Gbps via air on that. It is stupid fast and accelerations work, no CPU load, not that it lacks horsepower.

Basically there is no real need to stick with old routers. The entry level routers are pretty reasonable, even mesh works.

I think it important to note that just because a company is no longer providing new firmware upgrades, that in no way means the device will suddenly stop working or become vulnerable to security issues. In fact, by the time support ends, it often means all the bugs have been worked out. Unless the industry standard protocols change and the old device does not support those new protocols, I say don't worry about it until you need those new protocols. And then consider upgrading to a new device that does.

I think you are right, I am worrying too much; the problem perhaps is that people are finding new vulnerabilities as time goes on.

the problem perhaps is that people are finding new vulnerabilities as time goes on.
True. But as time goes on, all the "easy pickings", that is, the most serious, easy to exploit vulnerabilities have already been exposed and patched. This means if any new vulnerabilities are discovered, they most likely are very obscure affecting only a very few users running in very uncommon scenarios. Does that describe you? Not likely.

And 99% of the badguys out there are lazy bums looking for easy ways to rip off as many people as possible. So we have to ask ourselves in these situations, "what are the odds a badguy is going to target "me" and "my" network?"

So what about that 1% of the badguys? Those are the professional badguys who go after specific targets because they know those "marks" have something valuable they want. So again, we have to ask ourselves, "do I have something so valuable, a professional badguy is going to spend his or her time trying to hack "me" and "my" network?

Of course, just because the vast majority of us are "normal" users and unlikely to be specifically targeted by a determined badguy out to get us, we still must "practice safe computing", be prudent, and not lackadaisical about security. So of course, keep our network hardware current and use strong passwords and passphrases on our networks. Keep our computers and computer security current, and avoid being "click-happy" on unsolicited links.

Then party on!

This is true, but I worry about the other 1%
Take care and be aware, but not worried - unless you are responsible for maintaining very sensitive personal and financial information for a bunch of business clients too. But if a normal home user, being worried just raises blood pressure and hair lines.
