I want to set up a thumbdrive to add the authorized_keys to the .ssh folder, copy a firewall-start.sh to the /root folder and execute a sed command to modify the
/etc/dnscrypt-proxy-2.toml file to use the cisco server.

I read the instructions in the documentation. I don't have a Linux OS, so I used the 7800 to format the drive as ext2. I put the authorized_keys in a folder called ssh on the thumbdrive. I created a post-mount.sh in /autorun/scripts directory on the thumbdrive, too. I made sure it was chmoded correctly. I could not unmount the drive. I had to reboot the router to safely pull the usb stick out. When I plugged it back in, the only folder was lost+found. I reinstalled the files, pulled it out, plugged it back in and again the only folder was lost+found. Should I try it again with ext4?

EDIT: It worked with ext4. I had to add copying the authorized_keys to the script, too.

One other question: How do I unmount the usb drive? doing a umount /mnt/sda1 results in an "Invalid argument" error.

Okay, I think I figured this out...

the mount in /tmp/mnt/sda1 is not the thumb drive. It survives removal of the device. It's a copy of the thumb drive contents. If you edit the files in there, they do not get written back to the thumb drive. they will not survive a reboot. I believe the thumbdrive is automatically unmounted after the copy is made.

You have to make your own seperate mount point for the thumbdrive to edit read/write the files. I could not get ext4 to work. I used ext3 instead.

Here is my script:
Code:
#!/bin/sh

if [ ! -f "/root/firewall-start.sh" ]
then
  cp /tmp/mnt/$1/firewall-start.sh /root/.
fi

if [ ! -f "/root/.ssh/authorized_keys" ]
then
  cp /tmp/mnt/$1/authorized_keys /root/.ssh/authorized_keys
fi

sed -i -r "s/(server_names[[:space:]]*=[[:space:]]*).*/\1['cisco']/" /etc/dnscrypt-proxy-2.toml
 
No. Even if Entware would support it, Wireguard need kernel v 4.
I doubt Netgear will ever upgrade to that...

But both DD-WRT and OpenWRT (LEDE) have kernel 4+.

WireGuard requires Linux ≥3.10 but NG firmware have kernel 3.4.103 ...
I hope wireguard will be implemented in the NG firmware.. but it seems difficult unfortunately
The asus ac86 has better vpn performance and wireguard support but not openwrt ddwrt support..

Hi Voxel

Is there any chance you can post an announce thread i.e. with no discussions or similar for new firmware that I can subscribe to, as I only seem to find out about them by chance?
 
Thanks for your continued firmware support, it is appreciated!

What results should we see with stubby or DNSCrypt enabled using the Cloudflare link?

Edit: oops, wrong thread

I can not say for sure that this is a Voxel FW issue, but I have problems with ReadyCloud after the latest update. On the router it says that it's registered with ReadyCloud when I check the "ReadyCLOUD (Allows you to access ReadySHARE Storage from anywhere.)" box and I get "This router is registered with the following ReadyCLOUD user: me@me.com" screen. The shares show up as they should from an USB connected drive locally and I can access the shares on my network. But when I log into the cloud in my browser I can see my router but no shares are accessible. I have tried to "Unregistered" my router and register it again but even after putting in my ReadyCloud credentials I still can't access the shares on the cloud. I can not disable Network Neighborhood either. It looks like "Unregister" doesn't work for some reason. Is there a way for me to get this to work again without a full factory reset?

Login into you ReadyCloud Account (Netgear website) and delete you R7800.
Then login with telnet on the R7800 and type “cloud uninstall” and reboot your R7800. Now you should be able to register your ReadyCloud access on the routers WI again.

Thanks. I have never telnet'ed into the router so I have no idea how. Where can I find information on how to do that? I have Google'ed some and not been able to find it.
 
Not sure where to put this but here goes. Ive got a r7800 running 64sf. Recently defaulted and have setup wifi with wpa2 on both channels. Ssid's are different, only 2 of the eth ports are used 1 for pc and the other for a ps4. 2.4g is on channel 6 and 5g is on 149. The router runs rock solid, I can max out my line on wireless and hard wire. modem is an arris tm1602 with a 400/20 link.
Ill try to list as much of my setup, if im lacking any info let me know.
2.4g
20/40 coexistence is enabled
5g
implicit beamforming, mu-mimo, and ht160 are enabled

My problems start when I wirelessly bridge a wrt1900ac v1. Its running current firmware Ver. 1.0.3.187766. The bridge is defaulted, wireless is setup the same as the r7800 aside from the ssid for the 5g on the bridge being different from the main router. Joining the 2 routers on the 2.4g channels works fine. Whatever bw i can get out of my 2.4g is transferred fine by the 5g band on the bridge. All the AP work fine for about an hour or so then 5g stops working on both routers. Although they still broadcast, the main router will not let you connect anymore. It goes thru a split second of attempt to connect then the tablet or phone gives up and jumps to the 2.4g and it connects without a problem and works. The bridge no longer accepts connections, i believe its a lack of dhcp. It appears that the bridge is still connected but is inaccessible. The eth ports work all the time. In an attempt to clear up the problem ive changed the 5g channel to 36, on the bridge, to see if congestion was the problem, that didnt work. In order to get the main router to accept connections on 5g the router needs a reboot, it hasnt recovered by simply shutting down the bridge. Am i going to far in trying to run these routers together, would rather to get it working vs. getting another router or a mesh. If I need to post more info let me know. Any suggestions? TIA

further update:
tried another router d-link dir825b1 and the exact same scenario occurs only difference my r7800 went down in about 20 mins.

Thank you for your help. I got telnet enabled, ran 'cloud uninstall' from the telnet prompt and rebooted. Still no go. I did it again but rebooted from telnet. This time it worked and I got the router registered!

Can someone please tell me how can I change the resolver in Stubby from Clouflare to Quad9? I am noob with programming but I can copy paste the commands :D.
 
just fyi for anyone ht160 was the culprit big thanks to avtella for this comment on another thread
'For regular use leave it at HT80 for greater stability, and less chances of interference.'

This is for Asus Merlin. You will need to adapt it to Netgear R7800.
Code:
# cat /opt/etc/stubby/stubby.yml
appdata_dir: "/opt/var/cache/stubby"
dns_transport_list:
  - GETDNS_TRANSPORT_TLS
idle_timeout: 1900
tls_authentication: GETDNS_AUTHENTICATION_REQUIRED
tls_ca_file: "/rom/etc/ssl/certs/ca-certificates.crt"
#
upstream_recursive_servers:
# Quad9 Primary IPv4
  - address_data: 9.9.9.9
    tls_auth_name: "dns.quad9.net"
# Quad9 Secondary IPv4
  - address_data: 149.112.112.112
    tls_auth_name: "dns.quad9.net"
# Quad9 Primary IPv6
  - address_data: 2620:fe::fe
    tls_auth_name: "dns.quad9.net"
# Quad9 Secondary IPv6
  - address_data: 2620:fe::9
    tls_auth_name: "dns.quad9.net"
#
listen_addresses:
  - 127.0.0.1@5453
  - 0::1@5453
#
 
#1. Install Telnet
Hold down the Windows Key, then press the “R“ key.
The Run dialog box appears. In the Open: window, type:
pkgmgr /iu:”TelnetClient”
Click OK

#2. Login to the router using your web-browser:
http://www.routerlogin.net

#3. Enable Telnet login:
http://www.routerlogin.net/debug.htm
Check (Set a tick in the box for) "Enable Telnet". (No apply needed)

#4. Login to the router using telnet:
Hold down the Windows Key, then press the “R“ key.
The Run dialog box appears. In the Open: window, type:
cmd
Click OK.
Code:
telnet www.routerlogin.net
The password is the same as from the normal router login page http://routerlogin.net

Now you can try this:

#Stubby: To delete Cloudflare and activate Quad9:
Code:
sed -i '/# Cloudflare/,/cloudflare-dns.com/d' /etc/stubby/stubby.yml
sed -i 's/#\(.*quad9\)/ \1/' /etc/stubby/stubby.yml
sed -i 's/#\(.*9.9.9.10\)/ \1/' /etc/stubby/stubby.yml
sed -i 's/#\(.*2620:fe::10\)/ \1/' /etc/stubby/stubby.yml
/etc/init.d/stubby restart
#Stubby: To revert changes:
Code:
\cp /rom/etc/stubby/stubby.yml /etc/stubby/stubby.yml
/etc/init.d/stubby restart

To see it is working, visit e.g.:

https://dnsleaktest.com/
https://www.perfect-privacy.com/dns-leaktest/
https://cmdns.dev.dns-oarc.net/
https://www.dns-oarc.net/oarc/services/dnsentropy/

Also you can install the Kamoj add-on to get more information about your router, including Stubby:

Good Luck! :)

False positive. This is a common issue with NG logging. It's bogus
 
just fyi for anyone ht160 was the culprit big thanks to avtella for this comment on another thread

yea, i have issues with ht160 too. it's stable until i try to download anything (i realize everything you do on the internet is downloading, but i'm talking about downloading at high speeds), then the wifi signal dies
