Hello everybody!

Two quick questions:

1. What is the difference between the options: "Any Dropped IPs for Reboot" and "All Dropped IPs for Reboot" under WDS/Connection Watchdog.

2. What is the difference between the the 2 DD-WRT images: "dd-wrt_x64_full_serial_2GB"
And "dd-wrt_x64_full_vga".

Best Regards

So sorry!
I meant the difference between "dd-wrt_x64_full_vga" and "dd-wrt_x64_full_vga_2GB" not the "serial" one.

Um Dale Gribble. There is nothing in the WIKI about the difference between the 2GB versions and the other versions. The Wiki is wrong about the public version not having USB support. The Public versions are limited to 4096 connections and no WIFI support. This is really old information too on the WIKI.

I'm fairly certain that wiki update inputs are always welcome from people using x86/x86_64. A full detailed laundry list of differences would be ideal for all available images. I personally do not use x86* versions, so no investment or vested interest here. Looking at image sizes, I would tend to presume that the *2GB images refer to max RAM supported, but I wouldn't know.

The 2GB images have a larger partition.
Or more free space to store anything

That makes sense now after looking further. Trying to do some legwork to pass on because it seems that the community members who do use x86* aren't keen to provide anything to improve the complaints about documentation - not even linked topics.

Thank you! I have often wondered what the difference was. I have never tried the 2 GB version. I will use it the next time i flash a new image.

With my x64 setup, I just upgraded to the 2GB firmware. Where is this additional "free space" to store things?

The image has a 1,8GB partition, and there are two things on that partition: nvram and var.
I have no idea where the partition is mounted, as I don't have x86 dd-wrt at hand right now.

But according to the wiki, the partition is mounted to /usr/local (if that's still correct).

Yes, I ran "df" and saw it there. But even though I don't see a symlink, it's tied directly to /jffs. If I add a file in one directory, it appears in the other as well.

This is disconcerting, as I was hoping the extra space would be somewhere more stable. When I just did a firmware upgrade (which usually preserves all /jffs files), this time around it wiped out everything in /jffs and started anew.

I could set up a USB drive, but with the extra space that the 2GB firmware offers, I wanted to keep everything "in house."

My data in the /jffs/opt folder stays there, even after a reboot.
I also use the x86_64 2GB VGA releases.

Since I need ethtool (which isnt included in x86 builds.... -.-) I managed to install optware long time ago.
After a reboot of the device I issue mount --bind /jffs/opt /opt and have access to ethtool again.

I also store there several scripts for updating my domains.

I'm on a release from a few weeks ago though (before ipv6 imploded), dont know about last two or three releases, since I did not test them.
