Custom firmware build for R7800 v. 1.0.2.60SF

One question though. Is the export path command permanent, or will I lose it over a reset?
Do I need to add it to a file somewhere?

It is in my note for 1.0.2.59SF. Just create your own file

/root/.profile

which sets your PATH.

Code:
export PATH=/opt/bin:/opt/sbin:/bin:/sbin:/usr/bin:/usr/sbin

Buffer Bloat is only a issue when maxing out your connection. So unless your everyday activities are running speed tests or downloading massive files BB is not going to be present.
I noticed spikes in online gaming also...
 
is there any chance of having LEDE, maybe in the future, with proprietary drivers ???
Try going to the OpenWRT forums and ask your question. Unless someone here contributes to the OpenWRT project, you probably won't get any answers.

FYI - LEDE does not exist anymore.

Announcing the OpenWrt/LEDE merge
As of January 2018, both the OpenWrt and LEDE projects agreed to re-merge back under the OpenWrt name.
 
I cant't install linux on imac now.. Is it possible to activate ssh without using the usb key?
It is not clear what for to install linux. If you need ssh on your R7800 it is possible to set up ssh access using the router itself (see Appendix A in my README).

And telnet to router is working BTW for some minor changes w/o ssh...

I did some tests. and the spikes seem to be due to the automatic search for wireless networks. but the bufferbloat in the tests remains..
I must use linux to format the usb key with ext2/3/4..
Would not it be easier to publish images of firmware with ssh activated? :D

You can do that from router console entering by telnet to your R7800.

SSH is working immediately after flashing. W/o any activation. Even if you do not use it. It is not "activation" but your own key to to enter to the router by SSH. Your own key and nobody else could enter w/o your key.

You can check out my wiki
https://sites.google.com/view/netgearr7800/home

I mostly use an older macbook at home, so it covers setup including ssh on a pc and a mac.
mac requires use of their built in terminal program, but you can cut and paste from the wiki for most things.
The most complicated thing was installing telnet, but cut and paste one line at a time and should work fine.

You also need some type of storage device plugged into the router, can be anything as long as the router can read/write it.

Who is at a loss to create and install authorization key.
Via telnet
root@NETGEAR:/$ passwd
type password for root and press Enter key, then retype password and press Enter key.
Then
root@NETGEAR:/$ vi /etc/init.d/dropbear
type i and remove -s in this line
$DROPBEAR -p $PORT -a -s -P $PIDFILE
then press Esc and write changes using :wq
Then
root@NETGEAR:/$ /etc/init.d/dropbear restart
Now you can connect via ssh, using the root password and without authorization key.
You can also change the port

Hi Voxel,
I read on one of your previous threads that you recommended to erase the overlay_volume partition to avoid possible conflicts with other firmware using this sequence:


1) enable telnet: http://191.168.1.1/debug.htm
2) telnet to your router IP
3) format overlay partition running the command from telnet:
mtd erase overlay_volume
4) hard reset

When I do this I receive the following error code:
Could not open mtd device: overlay_volume

Here is a copy and paste from my telnet session
>>
=== LOGIN ===============================
Please enter your password,It's the same
with DUT login password
------------------------------------------
telnet password:*******
=== IMPORTANT ============================
Use 'passwd' to set your login password
this will disable telnet and enable SSH

Done! I made key on /tmp and copied on usb key with NTFS system that works also... Copied on mac with readyshare.
ssh -i id_rsa root@192.168.1.2

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@

@ WARNING: UNPROTECTED PRIVATE KEY FILE! @

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@

Permissions 0777 for 'id_rsa' are too open.

It is required that your private key files are NOT accessible by others.

This private key will be ignored.

Load key "id_rsa": bad permissions

root@192.168.1.2: Permission denied (publickey).
chmod 0600 id_rsa

and now everything is ok .. a bit cumbersome maybe not even worth it.
it would be enough to log in with the disabled keys ..


however the bufferbloat is improved by setting buffer at
net.core.rmem_max = 163840
net.core.wmem_max = 163840

i take A on bufferbloat test instead of B.

Perhaps it could be improved again. Should I increase or decrease the buffer? i have 100 + down / 20up line ..

EDIT: with mac is ok but downloading with xbox is now much slower. it would be better perhaps to increase the values... now I go back to the default values later I will do other tests
EDIT: i run other test with default values and results are A on bufferbloat..
In fact these tests are not very reliable ..

I can be satisfied with this router and the Voxel firmware. I was undecided whether to buy the r7800 or the linksys ac3200.
In the end I think I made a good choice even if I have not tried ac3200 and seems to have a higher power of the antennas in the specifications..
thanks 1000

Having trouble with attached devices again. Stuff isn't being written to memory. Going back to .54 version.

Sorry mean .52. My wireless speeds were getting bogged down too. Like a memory buffer/cache was getting full?

Had it right the first time. .54.

Way faster, router GUI way faster. Attached devices works as expected.

Probably something was changed since my recommendation, sorry. BTW did your use my version or stock when formatting overlay? Usually this procedure is performed when changing from DD-WRT to stock using some specialized stock fw version.

Strange. My devices are shown OK with 60SF. Speed should be the same. Maybe reset is needed.

"Maybe reset is needed."

Tried. Same result after a day or so slows down and attached devices are goofed up.

Does not happen with .54.
 
I am on 1.0.2.60FS version and after each restart I am getting from web interface prompt to update OpenVPN package. Is it possible to get rid of that message? How can I upgrade OpenVPN package?
