In case of faulty that particular nvram partition you would get an error message. But obviously that doesn't mean whole memory is fine.
Anyway better not erase other partitions.
In regards to reset full cleanup can be achieved by performing hard reset (or from gui) plus erase command.

I ran the tenet command again:
root@R7800:/$
root@R7800:/$ mtd erase netgear
Unlocking netgear ...
Erasing netgear ...
root@R7800:/$
root@R7800:/$

Did not lose the 7800's internal config settings. I then rebooted the router using the reboot button found in Advanced Home - Router Information. (IOW, a soft reboot). 7800 rebooted with all internal config settings intact. Erasing the nvram did not cause the router to lose its config settings. I did not need to reload the saved off config file.

Is this what you expected presuming the nvram was not defective?

EDIT: I just powered cycled the 7800. It rebooted with all internal configuration intact.

I want to thank Voxel for his amazing tweaks on the firmware. Together with the hardware mods I did with heatsinks and two quiet fans the performance is really nice.

Any help on reading out the temperatures of my R7800 with Voxel firmware? I looked into the entware but I honestly have no clue how to get that going. The readme doesn't make much sense to me either.

I am also still curious to get the Asus AC68U with Merlin firmware to see if there i's improvement in storage transfer speed over SAMBA compared to my modified R7800.

I said you need that one: https://www.snbforums.com/threads/k...800-x4s-and-r9000-x10-temperatures-a-o.55063/
Otherwise you can try to configure SNMP plus some nice graphing tool:

Not sure however about MIBs and if they provide OID for temperature.

I tried to enable Telnet on the R7800 but keep getting code 23 errors when trying to access it...


When I try to enable Telnet it gives me The
CGI script took too long to produce a response


EDIT: A reboot and re-enabling telnet worked.

That was useful THANKS
Temperatures CPU / WiFi0 / WiFi1 47 / 42 / 40 under full load copying large files

What can I say. I guess the cooling is working well now. Seems like there is room for an overclock.

Any way to overclock with Voxel firmware?

Running R7800 v. 1.0.2.64SF since the day Voxel posted it.

This morning, my internet connection was very flaky and eventually crapped out to my desktop Win 10 computer. I tried to login to the 7800 and could not. I power cycled the router. I was able to login but the 7800 had lost all config info and began the setup for a new 7800. Voxel 1.0.2.64SF was still running so the router did not fully reinitialize to the initial factory firmware. Of course, the log was reinitialized so I have no log history as to what might have happened.

My saved config file was old so I re-entered all settings manually and saved off a new config file should the router lose its mind again. After four hours of running, so far so good.

Looking for feedback as to what might have caused this and if others have had this happen to them.

This just happened to me as well. Some Wifi client could connect, some couldn't. I manually rebooted the unit and the config was back to defaults. I've had this unit since 2016 and I've been running Voxel's firmware since he started making them. I update about 10 days ago to 64SF from 62SF. I could be a hardware issue, but I suspect something in the underlying firmware is wonky and it's nothing to do with Voxel's changes.

You are correct. On the official Netgear Forums, people are complaining since upgrading to .62

Since my 7800 lost its config info (and I had to reconfigure it), it hasn't happened again. I agree with your thinking because if it was a hardware issue, I think it would have happened again by now.
 
Hi Voxel, I've been using your firmware and they've been great. Thank you for your builds.
I do have a VPN server issue with this build where my IOS devices connect, but cannot browse the web or communicate to any internal devices. I've tried regenerating the cert by entering "/etc/init.d/openvpn regenerate_cert_file" through telnet. I've also tried resetting to factory default and "mtd erase netgear". I reverted back to v1.0.2.63 and VPN is working fine on that build. Any ideas?

Thanks for you report. OpenVPN version is changed in 1.0.2.64SF. Maybe some incompatibility. I need a time to check this. Currently my ISP changed setting and now I do not have real IP (visible from outside) to check this immediately.

I've checked. New version of OpenVPN (2.4.7) is OK. It is working. Most probably what you need: just to enforce selection of the radio button in OpenVPN GUI

Code:
TUN Mode Service Type    (*) UDP (2.4.x clients)   ( )TCP (2.4.x clients)
TAP Mode Service Type    (*) UDP (2.4.x clients)   ( )TCP (2.4.x clients)

or

Code:
TUN Mode Service Type    ( ) UDP (2.4.x clients)   (*)TCP (2.4.x clients)
TAP Mode Service Type    ( ) UDP (2.4.x clients)   (*)TCP (2.4.x clients)

I.e. make sure that something from the radio buttons in OpenVPN GUI is choosed (*)

And better do it for 1.0.2.65SF (coming soon, 20-40 min)

Hi Voxel,

I am experiencing a similar issue as NathanG, but I am able to access the internet but not any local devices e.g. router, pc, etc. I updated to the newest version 1.0.2.65 but am experiencing the same problem. If I rollback to version 63, the issue is resolved. However, I did find when I'm on version 64 or 65 and go into the OpenVPN iOS app and change the setting 'Allow Compression (insecure) to Full I am then able to connect to the internet and local devices through the VPN. This setting was set to 'No' when using version 63.

Were you able to get it to work without using this option in OpenVPN? I only have access to iOS devices so I cannot test this with Android.

Thank you for your time.

Oh yes, thank you. I remember there was the same situation with my home VPN server (not router but PC)... Two or three months ago. When I could not use my iPhone. So finally it was solved by enabling compression in OpenVPN settings on iPhone. IMO it is problem of OpenVPN version for iOS. And BTW according to its log (on iPhone) it is secure.

How I checked with 65SF: just running downloaded Windows and SmartPhone client configs (TAP and TUN) on my laptop connected to WAN of R7800 and by connection this laptop to R7800 OpenVPN. Both were OK and I was able to reach second laptop connected to target R7800 (LAN, Wi-Fi).

I do not have Android smartphones too...

Voxel.
 
Forgot to add: my home OpenVPN server (not R7800) is using 2.4.6. Not new 2.4.7 used in 64SF/65SF. So again: IMO it is problem of OpenVPN for iOS.

Oh. I see. Thank you
 
#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://ipleak.net/
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:
https://www.snbforums.com/threads/k...800-x4s-and-r9000-x10-temperatures-a-o.55063/

Good Luck! :)
Why did you use 9.9.9.10 instead of 9.9.9.9? I'm about to try it.
 
I see the reference to .10 vs .9 but don't know why I would avoid the security advantages of .9. Guess I don't understand.

Edit: Are you saying with Voxel's stubby code in use the quad9 link shouldn't be 9999 as that security is already active, that it would be in conflict, so use 999.10?

Hi

I'm running my R7800 in AP mode but would like to run OpenVPN Server, which is greyed out. If I change to router mode, will I just be able to re-configure wifi settings to be an AP as well or are there other things I should be aware of? In other words is AP mode just disabling various settings for simplifying the UI?
I'm using the LAN port for the internet connection as per previous advice about potential data corruption with the WAN port.
I know I'll need to config my internet router and firewall to pass connections.

I wasn't really reassured by a thread about this on the netgear forum https://community.netgear.com/t5/Nighthawk-WiFi-Routers/VPN-while-on-Wireless-AP-mode/td-p/493450
 
AP is is just that wireless AP mode. When in this mode, most router features and functions are disabled. This would probably also include VPN as VPN needs WAN side access to the LAN side. When in AP mode, only LAN side connections are accessible. Most router features are disabled and would need to be configured on a different router in front of the R7800 running in AP mode.
