Hello Guys.
can anyone confirm me after installing fresh openwrt how much Software free space available in wrt1900acs V2.
I'm using Netgear R7800 it's has 70MiB+ software space i Need another R7800 but it's not available. i found wrt1900acs v2.
can anyone confirm...
The amount of available space will depend on which version of OpenWrt you are using.
[EDIT: The calculation below is based on the image which the OP has clarified comes from an R7800]
But, based on your picture, there is 22.41MiB available (28%) on your device. This suggests you have installed packages or are otherwise using about 72% of the space on your device. By that math, there is ~80MiB that should be available if you were to reset to defaults.
this was demo image. I'm using R7800 it has above 70+MiB. but currently it's not available. i need another.. i found wrt1900acs V2.
if anyone using it they can confirm it.
The wrt1900acs, like all other Linksys mvebu routers, is dual-firmware partitioned, 2*(6+34) MB, which should leave you with ~20-25 MB free space for the overlay).

oho it's too low. 
i want at least 50MiB.
Both of the devices discussed in this thread (WRT1900ACS, R7800) have USB ports. Therefore, you can consider extroot as a means of increasing your available storage using a USB stick.

Only few devices (like the r7800/ xr500) will give you more than ~20-64 MB (minus the space actually used by OpenWrt kernel+rootfs) in total. Most contemporary devices come with 128-256 MB NAND flash in a dual-firmware setup (which halves the usable space) and often 'waste' quite a bit of the space for custom vendor partitions (and NAND/ ubi also needs to set some space away for ECC and wear-leveling purposes).
I'm running vanilla 23.05.2 on my WRT1900ACS V2 (no extra packages in overlay) and I have 22.96 MiB available space after firmware is installed.

thanks for confirmation.. any method for space up? it's too low.
Yes.... as I said previously:
That is the only (practical) way to increase the space by any meaningful amount. You can get maybe a few MiB by removing some packages from your install image, but that's not going to get you in to the 50MiB territory. But extroot is simple and will give you plenty of space (based on whatever size usb stick you use).
