  • Known issues : openVPN , default has --pushroute instead of --push route, need to manually alter nvram variable openvpn_value

Changelog 2015-02-08

Additions:

  • iperf3 added (for devs, requested by Pietro)
  • LiME loadable kernel module, whole memory dumping (for devs)
  • (front) physical WPS Button Override, to run any arbitrary command, such as poweroff.
  • 'Network settings' > DNSMasq 'additional configuration' (Netflix w/ Hulu bypassing etc.)

Fixes:

  • IPoEoA connections with VLAN tagging now work; e.g. Sky Fibre (UK), TalkTalk fibre (UK)
  • nfs now starts correctly on USB hotplug, fixing: "daemon.err mountd[1854]: unable to register (mountd, 1, udp)" - Created retry patch
  • Various minor updates/improvements/fixes.

Updates:

  • nfs-utils 1.3.0 > 1.3.2
  • busybox 1.22.1 > 1.23
  • dropbear 2014.65 > 2014.66
  • sqlite 3080301 > 3080704

Changes:

  • 'xDSL Advanced', more DSL stats views available , refreshable. (requested bulldog147)
  • 'Lan Setup', warning on about disabling DHCP disabling DNS.

Changelog 2014-10-26

Additions:

  • Network Traffic menu entry that displays all interface traffic directly from kernel.
  • Added two extra Filter entries to Automatic (if you are already using it you will need to manually delete automatic.data and let it regenerate to make use of them)
  • openSSL binary added to firmware image for TLS key gen for openVPN
  • 'Network Settings', new options; openVPN port change and SSH(Dropbear/SFTP) WAN port change. [LAN still on 22]

Fixes:

  • Patched bug(SSH2_MSG_UNIMPLEMENTED) in Dropbear 2014.65 , also now supports ECDSA keys.
  • Fixed issues where 'state' wasn't showing correctly in 'Network Services' with inadyn-mt
  • VLAN tagging can now tag WAN port as well as xDSL port, to support FTTH (fiber-to-the-home)

Updates:

  • Added more info to 'Attached Devices' such as arp cache/scan, dnsmasq leases and MAC <> OUI (vendor/manufacturer) lookup. Thanks to Netgear forum members for suggestions!

Changes:

  • openVPN now uses TLS keys by default, these are generated the first time it starts and stored in nvram (available as files in /tmp/CA). If you were previously using it with static key, you need to delete the 'openvpn_value' nvram variable to let it regenerate.
  • Have redone most of the log outputs using JS/AJAX and display them in reverse order so newest entries are at the top. Should also help browser compatibility.
  • Samba logs into main system log
  • Updated bits of 'Network services' page and backend script to reduce delays.

Changelog 2014-09-29

This replaced 2014-09-28 which had a problem with samba

Additions:

  • openVPN 2.3.4 (not affected by ShellShock, no auth-user-pass-verify in default config [and no bash shell anyway])

Fixes:

    (thanks to help from 'erm67' in decyphering /proc/switch!)
  • Fixed occasional race condition with dnsmasq restarting before ports were freed.
    (don't understand how it happens but adding a retry loop in the source fixed it.
    The version change also fixes another possible race condition problem)

  • Retracted using ionice for TBT and DLNA

Changelog 2014-02-14

Additions:

  • Ad blocking via DNS (dnsmasq) - [default using http://pgl.yoyo.org which isn't too large and yet still blocks 99%, can be changed via nvram parameter 'adblock_blocklist', if dnsmasq formatted]
  • Additional DNS server can be added in addition to DHCP aquired ones by adding it's IP with nvram paramter 'wan_dns_extra'

Additions - Testing: [feedback please as untested]

  • VLAN tag (WAN VLAN ID) on atm0 interface (for VDSL [e.g. BT Infinity, ID 101, remember transfer mode needs to be also PTM])
  • IGMP Proxy (IPTV)

Fixes:

  • Removed the possibility of race condition in acos_service when wan is going down and up where it may be reading/writing/moving/deleting resolv.auto file at the same time.
  • Few minor GUI tweaks

Changes:

  • Dnsmasq now doesn't poll for resolve.auto, relies on wan up/down, (will save a few CPU cycles)
  • Time/date set via busybox's ntpd on wan up (time.nist.giv & time.pool.org). No longer running timesync with Netgear's servers, (will save a few CPU cycles)

Changelog 2014-01-20

Updates:

  • Busybox > 1.22.1
  • Samba > 3.6.22

Fixes:

  • Patched pre-existing bug in lld2d (link layer topology discovery daemon) so when it randomly renames the LAN Setup > Device Name it goes to a default DGND3700 and not "802.11 Broadcom Reference", which breaks things (such as Windows 7 'network map')
  • Transmission startup script will no longer cause a 0 byte config file if the drives full.
  • A few other minor fixes.

Changes:

  • Enabled MaxMTU setting to 1492 on PPPoA

  • Most programs/services now separately enabled/disabled via the 'network services'.
  • miniDLNA now referred to with its new name 'ReadyMedia'
  • more filtering of webui input to block anyone entering invalid characters that may break parsing

Changelog 2013-12-20

Additions:

  • p910nd non-caching print server daemon added, autostarts on USB printer hotplug. (Appsocket/HP JetDirect , port 9100)

Changes:

  • Altered ADSL 'Target SNR Margin' adjustments on web gui to have finer grained control (10% increments)

Changelog 2013-11-27

Additions:

  • telnet client as requested
  • crontab/crond as requested (and cURL executable). Setting nvram option cron_value with a normal crontab entry will make crond start using that value.

Updated:

  • rebuilt MIPS build toolchain with all available patches (fixing daemonize bug)
  • minidlna to 1.1.1, now running properly daemonized. (Netgear worked around this by leaving it running in debug mode!) It should take up less resources now doing a scan too & work with more tv's etc.
  • openssl 1.0.2
  • all the (A/V) libs that minidlna uses. (ffmpeg 2.0.2 ,libogg 1.3.1, flac 1.3.0 & zlib 1.2.8)

Fixes:

  • dnsmasq now back to low CPU usage & not crapping out (setting --query-port=0), thanks to a tool called dnsblast that let me get to the bottom of it after weeks of fiddling and trying to find a reliable test.
  • unplugging a usb device should stop services and cleanup everything properly.
  • other minor things I can't remember now as it has been so long since last release.

Changes:

  • ionice reducing I/O priority of transmission and minidlna to get low dibs order on the usb drive and not hog it.
  • multitude of kernel patches from Olegs Wl-500g firmware
  • Using ISO-8601 for firmware numbering. (FYI Netgears choice '10201736' is month:10 day:20 hour:17 minute:36, no year)

Changelog 10201736

Additions/Improvements:

  • udhcpd nuked, DNSMasq now doing DNS and DHCP, featuring;
    • resolvable LAN hostnames including the router
    • DNS query caching (including local caching for TBT trackers etc.)
    • simultaneous query of DNS servers, using fastest.
    • some protections against attacks involving DNS
  • PXE boot enabled, with two flavours of Memtest86 currently bootable, via TFTP > HTTP (iPXE > PXELINUX), F12 on most systems at boot. [expansion in mind, pull larger stuff from the USB drive]
  • Can add LAN/Ethernet port to the bridge (to act as 5th LAN port)
  • Renice original default programs to low priority on startup

Fixes:

  • Dropbear SSH Firewall enabled didn't stick after power cycle (moved on menu, now called 'dropbearfw')
  • Static leases work correctly.

Changelog 10121522

  • Automatic URL/Feed parsing fixed

  • Updated Transmission 2.77 > 2.82
  • Added Automatic 0.8.0 for automatically adding torrents from RSS feeds.
  • GUI page for dyndns
  • Added advanced Wifi menu back that was 'hidden' in original firmware, A-MPDU/A-MSDU aggregation, Beacon, DTIM interval setting.
  • Much more feature enhanced web GUI for ADSL, Dyndns, Torrent/Automatic settings
  • Shutdown/reboot from new menu shut everything down nicely first from inittab
  • Compiling firmware initially is quicker as enabled multiple job build (-j4) on most things [16m on Corei5].
  • Other minor things I cant remember.
