Router: Linksys E4200
Firmware: DD-WRT v3.0-r35916 mega - 05/11/18
Kernel: Linux 3.10.108-dd #19122 Fri May 11 18:24:52 CEST 2018 mips
Status: OK
Reset: No
Errors:
Here's something I noticed. Disabling wireless access to the webGUI has NO effect. Is this a known problem? Also have still been having weird issues with DNSMasq, but I think the problem is more related to the garbage Windows IP stack.... who knows.

EDIT: Things seemed to have settled out now. Uptime around 6 hours.

Smells like wrong timing to start services lan and ntpclient for the 5GHz radio in both routers... maybe a delayed start could avoid the problem?

Issues/Errors: Speed tests are worse than usual and bufferbloat is a B or C rather than my usual A or A+... maybe the test site, will try again later.

Aaaaaand, I'm a dumbass... slow speeds (above) were caused by VPN client being active.

Router: Cisco Linksys EA2700
Firmware: DD-WRT v3.0-r35916 (05/11/1Cool
Kernel: Linux 3.10.108-dd #19110 Fri May 11 18:13:34 CEST 2018 mips
Status: running but buggy, AP mode for wireless, ethernet WAN
Reset: yes when flash
Errors: time service ok, wifi ssid connections ok, running "cat /proc/mtd" in Administration -> Commands worked fine like the case of kernel-panic69, but WAN connections from Wifi still hang intermittently whatever TCP or UDP, only packets sent but no responses from router, so I have to disconnect the wifi from my phone and reconnect again so wifi TCP response again. It never happens in wired LAN ethernet connects, wired ethernet always work fine.

Wifi TCP hang whatever Facebook, Whatsapp, Chrome, Line, Wechat, Instagram, Youtube, or even just Google play store...... planning for falling back to the most stabler build 10-20-2017-r33555 of 2017

Oddly enough, my router doesn't stay on 24/7 and powering up, all settings lost. Re-configured, step-by-step, noticed some settings didn't 'take' between saving/applying and reboots and such. Don't know if it was a random glitch or what with 35916. Anyway, here, hold my beer.... Cool

Router: Netgear Nighthawk R7000P
Firmware: DD-WRT v3.0-r35916 std, Release: 05/11/18
Kernel: Linux wl-ap-eg 4.4.131 #3078 SMP Fri May 11 13:38:35 CEST 2018 armv7l DD-WRT
Status: Came up successfully, runs stable. 5 GHz WLAN starts to ignore broadcasts after about 2 hours of operation.
Reset: Tried NVRAM reset via Web GUI, didn't solve the problem.
Errors: 5 GHz WLAN ignores broadcasts after about 2 hours of operation

Details:
I have set up the R7000P in client bridge mode using its 5 GHz WLAN module. The access point the R7000P connects to is a Netgear R7000 which is also running DD-WRT and serving other clients (e.g. Linksys WRT600N). In this scenario, the R7000P (and only the R7000P, the other clients are not affected) seems to start ignoring incoming packets to the broadcast address FF:FF:FF:FF:FF:FF on the 5 GHz device after about two errors of operation. This can be clearly observerd by using "tcpdump -i any".

This problem breaks ARP and DHCP. A DHCP client, which connects to the 2.4 GHz device of the R7000P, or a DHCP client, which connects via wire to the R7000P, doesn't get an IP address.

I suppose that the driver for "eth2" (wl0: May 1 2017 12:43:53 version 10.10.122.301 (r658909) FWID 01-1ebebd8a) is the cause of the problem. I tried earilier versions of KONG and BS builds (which come with the same driver) and discovered the same problem. There are no eth2-related messages in the dmesg log. Especially, there is no log when the problem starts to occur. Sad

Resetting the R7000P to factory defaults didn't help.

It is definitely not a "packet loss" problem caused by bad radio channel conditions. Unicasts come through perfectly. The problem is independent from the channel number.

After reconnecting the 5 GHz link, the problem is gone for another 2 hours

A more detailed description of the problem can be found here: https://www.dd-wrt.com/forum/viewtopic.php?t=315026.

Kind regards,
Steffen

I noticed hitting <Apply> or <Save Settings> sometimes might cause the WEBUI to hang. Hadn't figured out a pattern to report.

s/beer/coffee. It's rare that I drink adult beverages Wink 35927 seems to be much more stable than 35916. 12-hour uptime yesterday with no incidents. Good to know that the webGUI hang is something to keep a lookout for, although I haven't seen any issues with it on the latest BS build.

i really think about removing these fake bridge modes. all newer broadcom drivers using the dhd driver do not support these bridge modes anymore. they may crash. they may not work. sorry. i have to ignore this. use client modes, maybe use the eoip tunnel feature to build your real bridges. fake bridges are shit anyway and they do not have any arp support. they just simulate the behaviour. realize finally that this is no wds mode. it has no real bridge behaviour. this is also not possible without wds

thanks for the comment BrainSlayer, have you tested WDS lately on ARM? i have not been successful in a working WDS connection between R6300v2 and R7000 (both ARM).

Status: no issue for 2 days
Reset: yes
Errors: before reseting config, LAN didn't work config (PC couldn't get IP), but WAN and WLAN were ok. After reseting config then everything are good, probably old config was corrupted because the router auto reverted to stock firmware in the first few attempts to flash dd-wrt.

A piece of news about coffee:

Coffee sold in California must carry cancer warning, judge rules
http://www.bbc.com/news/world-us-canada-43594645

Given the amount of pollution on Earth, it's hard to say whether these drinks are safe for consumption or not. Both green tea and beer might have insecticide and weedicide. Smile

Back to our usual DD-WRT testing ...
