Will future releases shrink again in size?
The latest version at the moment which would fit is 10-31-2022-r50755. Is it safe to use this or do the newer versions from last week contain security updates?

There is really only one way to know if the wiki is correct, and really only one way to know what builds can flash to this router. Flash and report. I can't find any flash reports on this router dating back to your last inquiry about firmware in 2017 off the top of my head:

Suddenly, the forum search dropped your last two build thread posts (or I ignored them?). Either way, you're the only person whose reported on this device that I can seem to find between the in-forum search function and a web search.
The worst that could happen is you brick the router and have to recover it. The best method of testing to see if it will flash is via CLI (PuTTY) over telnet / ssh (substitute newer revision folder info, i.e. 11-06-2022-r50814, in place of the example):
Code:
cd /tmp
wget http://download1.dd-wrt.com/dd-wrtv2/downloads/betas/2022/10-31-2022-r50755/broadcom/dd-wrt.v24_vpn_generic.bin
write dd-wrt.v24_vpn_generic.bin linux
So if I follow your instructions I might end up having to solder a JTAG-cable etc.? What are the chances?
As I'm not using the VPN-functions at the moment, I think I'd rather change to std_generic for now.
I read that many users don't do a reset anymore when flashing a new release - is there a specific risk to flashing from vpn_generic to std_generic without reset?
I tried flashing vpn_generic from r50841 using telnet but it failed - it's too large.
Then I flashed std_generic successfully, but I have issues with the wifi, even after doing a 30/30/30 reset and reentering all my settings manually in the web interface. I can connect to my wifi network, but as soon as there's traffic like accessing a website, the router reboots and then there is a another network with the SSID 'dd-wrt' active, and it stays active even if I set wifi network mode to 'disabled'.
Internet access via ethernet works fine so far.

Does this device have bootfail handling, is it enabled, and if enabled, how many bootfails before it resets the router? I don't know of any reason why your router would reset wifi settings or settings in general upon using wifi to access the internet without seeing your configurations.... _________________ "Life is but a fleeting moment, a vapor that vanishes quickly; All is vanity"

I would use the command "free -h" to see whether RAM (size: 16 MB?) had been used up.
Also, the router might boot twice to test certain features (e.g. CTF). So don't start using it right after powering it on. Give it a few minutes to settle things down.
If it's really RAM issue, you should try to disable some services first (e.g. Telnet, Traff) before doing everything else. _________________ Router: Asus RT-N18U (rev. A1)

Now it seems to me that the 'dd-wrt'-network only comes up for a short while during the reboot and then disappears as my own SSID becomes active.
The rebooting happens not always at the first sign of wifi-traffic, sometimes I was able to browse several websites and stream video for over a minute. It's just highly unstable, always leading to reboots, even when the router has been running for half an hour, while working well through ethernet.
Here is the free -h result while wifi was working for a moment with traffic:
Code:
root@DD-WRT:~# free -h
total used free shared buff/cache available
Mem: 13276 6424 1824 0 5028 0
-/+ buffers/cache: 6424 6852
Swap: 0 0 0
This after I changed wifi settings in the web interface:
Code:
root@DD-WRT:~# free -h
total used free shared buff/cache available
Mem: 13276 6552 832 0 5892 0
-/+ buffers/cache: 6552 6724
Swap: 0 0 0
Right now I had another problem that internet access via ethernet suddenly failed after 15 min up-time, while the web interface of the router was working. I just clicked 'apply settings" on the setup page and then the internet access worked again, without rebooting the router.

The default "dd-wrt" SSID should not be coming up that I know of if you have set a different SSID. Even though you have done a 30-30-30, you may wish to also do an 'nvram erase && reboot' at least once to clear any nvram corruption gremlins. Another issue could be a failing power supply adapter and the typical capacitor failures on the SoC PCB. As old as this router is, it wouldn't surprise me if both are culprits. We still have not seen your configurations or syslogs to possibly help determine if something is askew, but I digress.

RAM-related wiki references to read (and discuss):

There is no CTF kernel module for the Linux 2.4 kernel in use on these devices that I am aware of as it was introduced for 802.11n / Linux 2.6 kernel via Broadcom in stock firmware. _________________ "Life is but a fleeting moment, a vapor that vanishes quickly; All is vanity"

After unbricking, I've notice that the r47581_v24_std_generic size it's over the recommended 3.6875KB for this model (I seem to have read this somewhere).
Further checking indicated that the last "good size" v24_std_generic file is at r45130.
The following thread looks interesting, but a bit ancient. At least, the guy said "Everything is working so far". Maybe an old build for old routers worked better. But floppi was using a recent build? Or is he/she a newbie?

RAM seemingly went down to dangerous level, but mostly caches. My router does NOT have that cache thing.
What's the last DD-WRT build number that worked flawlessly in your WRT150N? WRT160N?? _________________ Router: Asus RT-N18U (rev. A1)

Is the 'nvram erase' command safe on the WRT160Nv1?
The wiki links to this post from BrainSlayer:
Quote:
a few devices. lets call them linksys (not all, but some) should not be treated with "erase nvram", since they wont recover the default data sometimes. i have seen lost mac addresses etc. this is why dd-wrt is also not erasing the flash anymore, but just restoring the default data if selected and keeping factory values untouched
I did the nvram erase && reboot without issues and reconfigured manually, but the wifi-problem persists as before.
Which logs and config do you need and how can I obtain them?
Moreover, do I need to trigger the reboot for the logs?
Here some logs after a manual, normal reboot:
