Not sure if you're calling logger too soon or not, but on the fly, it works just fine.
Code:
root@TL-WR1043NDv2:~# which logger
/usr/bin/logger
root@TL-WR1043NDv2:~# logger -p 3 -- "Oh frabjous day, it works."
root@TL-WR1043NDv2:~# cat /var/log/messages | grep frabjous
Nov 16 15:58:03 TL-WR1043NDv2 user.err root: Oh frabjous day, it works.

Configured the preferences manually this update as previous updates ended in boot loop or freeze whatever. These network crashes occur since several versions now.

Just out of curiosity, are you using HTTP or HTTPS for access to the WEB IF?
And are both HTTP/HTTPS access enabled?

Also WIFI wise do you have and VAP's setup?

What do the syslogs say here, anything to report?

Be well Wink


Only http configured (local). What's a VAP?
What should i look for in syslog? There a many many yellow dns messages, possible because of pihole. Like this:

DD-WRT daemon.warn dnsmasq[1628]: possible DNS-rebind attack detected: aax-eu.amazon-adsystem.com

I just had completely lost connection to other internet-router and tried to reconfigure for 2 hours Rolling Eyes. Bridge table only had vlan1. Had to reset and load configuration backup and now it's "eth1 eth2 vlan1" again. Souldn't in VLAN switch configuration be a row on the right to assign a bridge the LAN? Had a screenshot of old configuration that shows this, but in new config there is just nothing. (see attachment)

You have to configure 5GHz in a certain order. Set channel width, save; extension channel, save; then you should be able to select the available channel(s) for your regulatory domain.

Do you have CTF/CTF+FA enabled under "Shortcut Forwarding Engine" on the main setup page? Only caveat there is port forwards and other things may not work so well and you can't use QoS.


Was this in response to me (ethernet throughput)? If so, my shortcut forwarding engine is set to "SFE".

EDIT: Okay, reading through this now: https://wiki.dd-wrt.com/wiki/index.php/Hardware#Flow_Acceleration.2C_SFE_and_Cut-Through_Forwarding

Will give the options a shot per the test instructions and report back.

EDIT2: Any combination besides the default (FA disabled and Shortcut Forwarding Engine set to SFE) cuts about 1/3 of the bandwidth in the xfinity speed test. I can reliably select SFE to go back to the maximum of ~350 Mbps.

Do you know if anything changed this year in dd-wrt that would impact throughput out of the box? I swear I was getting faster ethernet speeds without fiddling with anything.

@efeman: You should be able to use at least CTF, if not CTF+FA to get maximum throughput. To answer your question: In short, yes. Sorry, I'm not a "quote whore" and I forgot to @ your username.

Router : TP-Link Archer C9 V1.0 (US)
Firmware Version : DD-WRT v3.0-r47618 std (11/05/21)
Kernel Version : Linux 4.4.290 #4422 SMP Fri Nov 5 06:33:48 +07 2021 armv7l)
Upgraded: from stock
Reset: Did a reset

Status: The webflash binary works fine. Router is up for 2 hrs, WiFi (2Gz, 5Gz) works. The signal strength is almost as good as stock. 2Gz speed is around 30 mbps, 5Gz speed is around 100 mbps (my ISP speed is 100mbps)

Errors: The factory-to-ddwrt binary will brick the router. Use the one from 04-05-2016-r29409. Then flash with the r47618 webflash.

This router can be de-bricked without a serial terminal. Check this video : https://www.youtube.com/watch?v=AU8RyW82Z2M

This is normal, in Status Channel, Rate, Uptime are all unknown, packets and signal always 0.
The AC87 uses an unusual chipset on 5GHz (Quantenna, qtn).
Set VHT80, upper-upper, other options as you like (all enabled in my case) and your devices should be able to associate.
Merlin can read e.g. the temperature, so it should be possible with a newer firmware-blob for DD-WRT as well, but... don't hold your breath.

Remember to connect LAN1 to some less important device if using that, see
https://openwrt.org/toh/asus/rt-ac87u

Router/Version: D-link-DIR880L.A1
File/Kernel: DD-WRT v3.0-r47618 std (11/05/21) [dir880-webflash-2021-11-05-r47618.bin], Linux 4.4.290 #4420 SMP Fri Nov 5 06:10:11 +07 2021 armv7l
Previous/Reset: 2_DIR-880L_RevA_Firmware120b01-01-i3se.bin [see Notes below]
Mode/Status: Gateway; running stable since 2021-11-10. CPU 80.8 °C / WL0 52.2 °C / WL1 49.8 °C. Operating with 2.4 & 5 GHz WiFi, plus wired Ethernets; DNSmasq for Adblock'ing; SShd & syslogd enabled.
Issues/Errors: . 1. Wi-viz shows only a limited number nodes with any details?

Notes:
The stock/factory D-Link firmware (v1.20b01) refuses to load the factory-to-ddwrt.bin via its webGUI. I resorted to downgrading the D-Link firmware to v1.07b08, using the Emergency Recovery procedure. Thanks to BLKT for pointing out:
Link to D-Link factory v1.07B08: https://ftp.dlink.ca/ftp/PRODUCTS/DIR-880L/DIR-880L_REVA_FIRMWARE_1.07B08.BIN [https://forum.dd-wrt.com/phpBB2/viewtopic.php?p=1226419#1226419]. Using this v1.07b08 firmware, the dir880-r44483-factory-to-ddwrt.bin loaded successfully. Then, using the webGUI, upgraded to r47618, using dir880-r47618-webflash.bin.

For more info on D-Link Emergency flashing HOW-TO: http://forums.dlink.com/index.php?PHPSESSID=np3a5ifnakiph3v1k2o1928f54&topic=44909.msg162511#msg162511

Since then, I read QUARKYSG's post: "I would suggest flashing the factory-to-ddwrt firmware via the Emergency Recovery utility of your DIR-880L. I think newer versions of stock firmware checks for signed firmware or something to that effect, making it impossible to flash third party firmware via the stock firmware upgrade page." [https://forum.dd-wrt.com/phpBB2/viewtopic.php?p=1170431#1170431]

Earlier posts reported problems with web browsers used in the upload/upgrade process. I used Firefox 94.0 (64 bit) for Linux Mint 20 Ulyana. After experiencing glitches, I did the uploads/upgrades of the factory-to-dwrt.bin and webflash.bin with Firefox in a Private Window, with all extensions disabled - no glitches.

Hadn't heard anyone referred to as a quote whore before Smile

I made sure it reboots after applying CTF and it's very clearly dropping throughput. I can try a reset next, but might there be some other feature that could play poorly in conjunction to reduce throughput?

EDIT: Looks like a factory reset did the trick. Was getting around 380 Mbps out of the box, and with CTF + FA enabled I'm getting around 950 Mbps as expected. Appreciate the advice there.

Now to figure out the shortest path to get the settings where I need them without a restore.

EDIT2: For fun, I tried restoring the backup I had made from before the factory reset. Sure enough, it's back to around 240 Mbps with CTF + FA. So, I'd wager something else I have enabled is interacting poorly with it.

And this is why we usually don't recommend restoring from a (bad) backup. So, the next step is to figure out which setting(s) break your throughput.

I picked IPv6 as the one "feature" I had explicitly enabled, and disabled it - the speeds jumped back up to 900+ on the xfinity test. I enabled it again, confirmed it slowed, and then ran against speedtest.googlefiber.net, seeing 800+ Mbps.

Also tried highspeedinternet.com/tools/speed-test
Interestingly, it's the same behavior as the xfinity test; IPv6 is slow, IPv4 is fast. Naybe the googlefiber test only runs over IPv4.

Any theories? Might CTF/FA not be playing well with IPv6 traffic?

I don't think CTF/FA are for IPv6, whatsoever. If there is no glaring urgent need for IPv6, why enable it?

I don't have a strong reason to I suppose, but I wanted the functionality available since it's there and I didn't have a reason to keep it disabled. But, at least I know it's a limitation for DD-WRT at least with my router, and I have a reason to keep it disabled.

I wonder if broadcom have versions of CTF/FA without IPv6 issues.

Hmm. CTF might be making my router reboot randomly. Now that I've actually enabled it for an appreciable amount of time, every few minutes the router is rebooting.

It might be a red herring but I switched back to SFE and FA disabled and it's been been stable.
