I think I read here something in the past about this issue but am not able to find it again.
Any hint, please please?

Wireless in OpenWRT is disabled by default you either have to edit /etc/config/wireless or enable it by Luci
I knew that. The point is that even after I've enabled the device in Network-->WiFi the WLAN led stays off and, of course, there's no SSID in the air!

I made some steps forward and one backward.
I installed "ATTITUDE ADJUSTMENT (bleeding edge, r28173)" from trunk.
Now WiFi seems to be working (I can detect the SSID and see the WLAN led is on).
But there was no web UI!
Luckily, as my usual, I had previously enabled SSH on LAN so I could log with CLI.
# opkg list-installed | grep -i luci
# _Nothing related to LuCi was installed.
As this is a trunk build, I (luckily) checked the opkg configuration in /etc/opkg.conf and fixed it with vi editor like this:
#src/gz packages http://downloads.openwrt.org/backfire/10.03/ar71xx/packages WRONG
src/gz packages http://downloads.openwrt.org/snapshots/trunk/ar71xx/packages

Any idea?
It could be as simple as doing:
mv /etc/config/luci-opkg /etc/config/luci
And then (re)starting uhttpd with "/etc/init.d/uhttpd restart"

How to flash a firmware image by CLI?
(Last edited by uqbar on 8 Sep 2011, 15:49)
Ouch. Looks like your UCI / LuCI install is in a mess.
You can flash from the CLI using the following (I would suggest using a "-factory.bin" image at this point):
mtd -r write <image.bin> firmwareThanks,
Sam
Well, before jumping out of the sinking boat I'd like to try to fix it.
Unless the trunk packages are broken, which packages should I pull in in order to have a minimal web UI?
You are confusing me: one day you edit the topic about flashing from cli in the wiki, today you claim not to know how to do that?!
Anyway, I would recommend to flash again (most likely a full image like Sam mentioned, not just a sysupgrade - you might have configs in the filesystem which don't fit with the version of the new packages) and after that follow the wiki step by step. If that does not work, post a log of all the steps you took.
I apologize if I confused anyone. I have a somehow decent knowledge about *nix administration but am also willing to use web UIs as much as I can.
I've tried to use 10.03.1-rc5 with just the web UI. But wifi is not wirking at all.
With CLI I've seen the hostapd was not running and had little idea on how to manually start it.
So I did an installation of trunk via web UI. But then the web UI was gone. So, CLI was the only way to go.
I know shell CLI, but have little idea on how the OpenWRT ditribution is organized. This is why I am asking.
Back to the issue.
I've reverted back to official firmware and then went to trunk-factory (the 8MB image, I mean).

For 10.03.1-rc5 I've found why the WiFi is not working.
The web UI is generating the wrong /var/run/hostapd-phy0.conf file.
Once I configured the WiFi stuff from web UI I went on CLI and checked the situation.
As reported the hostapd wasn't running. From the trunk (where it's the web UI that doesn't work) I saw that hostapd was running as:
hostapd -B /var/run/hostapd-phy0.confAnd this is the output got from running hostapd on 10.03.1-rc5 CLI:
# hostapd -B /var/run/hostapd-phy0.conf
Configuration file: /var/run/hostapd-phy0.conf
Channel not configured (hw_mode/channel in hostapd.conf)
Could not select hw_mode and channel. (-3)

random: Not enough entropy pool available for secure operations
WPA: Not enough entropy in random pool for secure operations - update keys later when the first station connectsand I can see the WiFi is now working almost as expected.
The only different thing is that in the web UI I asked for automatic channel selection, while in the manual edit of the file I had to put an actual channel number (1 to 11). I have no idea on how to ask for automatic channel selection.
I'll try also to file a bug about this.
I have same router (TP-WR1043ND v.1.8) running with OpenWRT backfire 10.03-rc5 and had just one problem.
After enabling wlan I was able to connect as a client to WEP. Than I installed wpa-supplicant and libopenssl. But I was not able to cennect to a WPA-PEAP acess point as a client, because the router has no hardwar clock and so the check of some certificates during the handshake fails. Setting the date before WLAN connection helped to solve the issue.

Thank you for the hostapd hint so I can debug.
I have a problem similar to this and I can say that the bug is due to the fact that there is no error checking.
In my situation I have correctly set the channel number but I have tried to use 40 mhz (linked) channels.
It seems that it is not yet supported on wr1043nd hardware and so hostapd fails. Changing the hosapd-phy0.conf file or changing the config via luci to use only 20mhz channels made the wifi up again.
So you have to check very carefully the options you can really use.
The discussion might have continued from here.
