Hi there,
I'm firstly approaching OpenWrt for my NETGEAR DG834-v4 router.
I followed the instruction and I generated the OpenWrt image.
Once flashed the firmware is running (both web pages and ssh ok) but I don't find the wifi configurations.
Typing 'uci show wireless' I have: uci: Entry not found
If I open the network page I only see the LAN (br-lan), WAN (eth0), WAN6 (eth0) inferfaces.
Any idea?
thanks!
Iād first confirm the config was generated at /etc/config/wireless
Wireless has its own page, in the menu under the interfaces.
You can regenerate the config of wireless by running the command wifi config.
No file
/etc/config/wireless
at all ... 
and no extra wirelss page under interfaces page.
This device has only 16MB RAM (and 4MB flash). See https://openwrt.org/supported_devices/432_warning for implications of low flash/RAM.
Ok, but this is a warning.
The firmware is usually working or not?
Otherwise which is the sense of the instruction page to build it?
The firmware are built automatically, so there's no person manually checking the space on each of the hundreds of devices OpenWrt supports.
Refer to the page for the most recent version usable on your device. If you discovered that you are out of space, the firmware is likely too large. You can report such firmware issues here: Report Devices Here With 18.06.0 Provided Image too big to save overlay
Further, custom images can still be created to work on certain devices, so an instruction page to build would still be relevant. Other reasons:
16 MB RAM is just unworkable with any newer kernel. There won't be space to load a wifi driver.
Ok, I understand.
But, I'm sorry, I missed to say that I followed the instructions on https://openwrt.org/toh/netgear/dg834g.v4 page.
So I used kernel 15.05-96348GW-11, file DG834GV4_V5.01.17_src/DG834GV4_V5.01.17_src/DG834GV4_V5.01.17_VPN.img by NETGEAR.
When I flash the firmware the nftp reports:
sudo ./nftp -u eth0 myImage-5.01.09-15.05.11.img
[sudo] password di stefano:

Uploading this is not recommended but press Enter if you wish to continue.Erasing flash, this will take around ten seconds...

Is it correct?
