Welcome to Broadcom r47720 beta release thread for reporting, feedback to developers & community benefit.
Please do not flash builds until installation is understood, risks involved and device specific recovery methods.
Avoid discussions, create threads for questions, general problems or use search; this thread is not for support.
Please list router model & revision, operating & wireless mode(s) and exact filename/firmware image flashed.


Downloads: HTTPS, FTP

CLI Flash: 'cd /tmp' then 'wget {file URL}' (http only) or 'curl -O {file URL}' (http, https, ftp). 'write {file} linux' then 'reboot'.

Trac SVN: repository since last build r47695 (mirror)

OpenVPN 2.5.4: Changelog, Guides, Server, PBR, DNS, Kill Switch, Watchdog, Reverse PBR, Client, Multiple, tips & scripts.
WireGuard 1.0.20210606/Tools: Changelog, Guides, Client, Server, Advanced, PBR, KS, tips and scripts. Thanks BS & egc!

Notes:
Experimental for 8MB+ K2.x devices: broadcom_K3X_mipsel32r1. • MIPS @ kernel 4.4. • TP-Link Archer C8 v2, v3 support.
MiniDLNACoovaChilliPrivoxyiperf3cakeFreeRADIUSOpenSSLdnsmasqUnboundTorAsteriskBusyBoxSquid SmartDNS mac80211
In-kernel Samba ksmbd 3.4.2++: default min/max versions revised. WSD updateANTFS/NTFS3 kernel mode driver+++
CVE-2020-26147, CVE-2020-24586, CVE-2020-24587 & CVE-2020-24588 Fragattack fixed. • Broadcom swconfig supported.
• 'Assign WAN port to Switch' gone, set Connection Type Disabled. • WebUI MAC Filtering (47184-47205). • Sputnik removed.
• 'Ignore WAN DNS' also ignores WAN domain. • Milkfish removed.
New DD-WRT inspired themes conversion by the-joker & BrainSlayer, micro builds excluded.

Issues, observations, and/or workarounds reported:
WebUI: Clear history or use a portable. Temporary cache bypass: Ctrl+F5, Cmd+Shift+R or new private window/incognito.
DNScrypt 1.95 can still be used in WebUI but v2 (not compatible) requires Golang and thus Entware. See Trac ticket #6246.
WDS does not work on Broadcom ARM devices (only MIPS<->MIPS) & bridge modes on k4.4 devices may sometimes work
in some configurations for certain builds but are not supported by the bcmdhd driver. Try client or repeater modes, but YMMV.
VAPs not working at boot was fixed for unbridged VAPs (40562-40566). Effective startup commands: see discussion thread.
If startup scripts do not work from USB add delay (wait script), sleep 25 or try Administration -> Commands -> Save USB.
Broadcom ARM devices if 5 GHz channels are missing via Telnet/SSH: 'nvram set brcm_unlock=1' 'nvram commit' 'reboot'.
Please report findings with steps needed to reproduce, configuration, clients, output, logs and important information below!

Important:
• For issues provide applicable info: 'dmesg' 'cat /tmp/var/log/messages', syslog klog, serial, strace, tcpdump, wireshark etc.
• Any firewall NAT or WAN issues, show output: 'iptables -vnL' 'iptables -t nat -vnL' 'iptables -t mangle -vnL' and /tmp/.ipt file.
• Gremlins: reset & configure manually, not restore a backup. Reboot. Search Trac & discuss in forum before opening tickets.
• Please include operating & wireless modes (e.g. Gateway, Router, AP, CB, WDS, Mesh) & relevant configuration information.

Router/Version: EA-6350 - Broadcom Northstar
Firmware: DD-WRT v3.0-r47720 std (12/02/21)
Kernel: Linux 4.4.292 #4445 SMP Wed Nov 17 13:06:24 +07 2021 armv7
Previous: r47510
Update Method: GUI
Mode/Status: AP/OK
Reset: No
Issues/Errors: None, except as explained below.

Great work. Thanks to all who contributed and make this great firmware.

One issue that has annoyed me is that if the router is rebooted, wl0 (2.4GHz) is either not broadcast or reverts to Wireless Security "Disabled" (although the GUI still shows Radio is "On" and "WPA2-PSK"). The Wireless Security GUI "Apply Settings" button must be pressed to enable wl0 and the encryption for wl0. This is not a new issue and has been present in older builds.

The wl0 settings for my EA-6350 are below:

Basic Settings Wireless Interface wl0 (2.4GHZ) - Max Vaps(16) -
Physical Interface wl0 - SSID [D-Link-G] HWAddr [48:F8:B3:DF:30:1E]
Wireless Mode: AP
Wireless Network Mode: NG-Mixed
Wireless Network Name (SSID): D-Link-G
Wireless Channel: 6 - 2.437 GHz
Channel Width: 20 MHz
Wireless SSID Broadcast: Enable
Sensitivity Range (ACK Timing): 500
Multicast To Unicast: Disable
Network Configuration: Bridged

Wireless Security wl0 -
Physical Interface wl0 SSID [D-Link-G] HWAddr [48:F8:B3:DF:30:1E]
Security Mode: WPA2-PSK
WPA Algorithms: COMP 128 (AES)
WPA Shared Key: **********
Key Renewal Interval (in seconds): 3600

The following nvram listings seem relevant. Seems after a reboot, nvram is reset as shown, but the GUI is showing the correct encryption setting. After applying the GUI settings, the nvram shows the correct settings and encryption is enabled. Also, since this router required a custom CFE, it's possible the initial nvram values come from the CFE values. My assumption is that once set, the nvram values should not change on reboot.

After reboot, nvram shows:
wl0_crypto=off
wl0_wds0=*,auto,off,psk2,D-Link-G,8********0

After pressing "Apply Settings" under Wireless Security, nvram shows:
wl0_crypto=aes
wl0_wds0=*,auto,aes,psk2,D-Link-G,8********0

@rodgerwheat: Ok, I have to ask, since I can't seem to find it in your 6 posts. Are you using XWRT-Vortex CFE on your router?

Also would help to know which browser you are using and if you are using private browsing mode with no add-ons or extensions loaded that may cause issues.

I would say Xvortex not XWRT-Vortex was used and I'm using Firefox browser with no unusual add-ons.
Here is the procedure I used to create and load the CFE:
You must run CFEEdit and change the following variables:


et0macaddr hw_mac_addr+1
hw_mac_addr from routers label
lan_hwaddr hw_mac_addr+1
serial_number from routers label
tc_passphrase from devinfo or nvram
tc_ssid from devinfo or nvram
uuid_key from devinfo or nvram

0:macaddr hw_mac_addr+2
1:macaddr hw_mac_addr+3
manufacturer_date from devinfo or nvram
and then save.

Load dd-wrt for EA6350 through TFTP
See How to Load through TFTP.txt

1. Rename the Xvortex CFE to 1.bin

2. Enable SSHd under Services tab in dd-wrt gui
Enable SSHd in Services, Secure Shell
Enable SSH Management in Administration

3. Use WinSCP to connect to the router by using SCP protocol
Change protocol to SCP, Port 22
Enter router address (ex. 192.168.8.1) for Host
Enter User name "root" and Password router password "xxxx"
Login

4. Transfer the file with WinSCP from your computer into the /tmp folder of the router

5. Open Terminal under Commands tab in WinSCP, enter:
mtd write -f /tmp/1.bin boot
then press Execute

Erase nvram
1. CFE> nvram erase

@rodgerwheat: If it was edited to run XWRT-Vortex/AsusWRT-Merlin, and not to continue being a native EA6350, that's probably part of the problem. Also, if you don't have the latest fixed version of the CFE file to edit, there may also be issues. Sir @egc and others know more about this than I do, but that is possibly part of why this is happening.

kernel-paninc69..Thanks for the reply. The custom CFE is probably the problem. Although the NVRAM values set with the modified CFE do not include "wl0_crypto", the CFE program may clear this value. The EA6350 is a good router, but it may be time to find a router that does not require CFE modification.

@rodgerwheat, the custom CFE probably messes with nvram variables.

You can try to find if there is a newer CFE, there is for the EA6900 although the old one is rock solid.

MAC addresses should be +2 +4 for DDWRT.

The guide for the EA6900 will also get you some guidance:
