Thanks for the explanation of how to start DHCP on the WiFi interface.
At the moment I'm struggling to find out where to enter these deatails. In an effort to get some clarity in my /etc/config/wireless, I deleted it and rebooted and got one generated by the system which created three wifi-devices and three wifi-ifaces.
Running iw dev shows phy#2 phy#1 phy#0. How do I know which each refers to ?b
After not making any progress for a week or so, I thought I'd give it another go by starting from scratch, but am unable to get /etc/config/wireless created automatically.
dmesg shows that my Intel PRO/Wireless 3945 is recognised.
lsmod | grep 3945 shows
cfg80211
compat
iwl3945
iwlegacy
mac80211
iw dev and iw list do not show anything
Can anyone suggest what I might have overlooked?
Any messages about missing firmware files (dmesg)? dmesg | grep -i -e iwl -e ipw -e 80211 -e firmware, as well as ip a might also provide further clues.
There is something like
ACPI [firmware bug] query ignored
and three entries related to iwl3945.
Is /etc/config/wireless automatically created once the correct driver is detected?
Looks like something is missing but I don't know what.
It should be, yes.
If you manage to scan (iw dev … scan) and get results back, wireless should basically work.
Looks like I incorrectly installed kmod-iwl4965 or iwl4965-firmware.
I do now have a /etc/config/wireless which only has a single wifi-device and wifi-interface which I never got before.
Scanning works OK and I can see the SSID I want to connect to, but can't yet figure out how to connect to it. I've set the ssid and key in the wifi-iface and set encryption to wpa. Mode is set to sta and network to wan.
Do I need to set channel, band and htmode. They are set to 36, 5g, HT20 by default.
How do I manually connect to the broadband router?
The wifi led is on and the list of ssids scanned shows the one I want to connect to, so I should be close to connecting.
Scan from within luci, click on connect of the ESSID you want to connect to - and let yourself guide by luci through the rest.
I don't have access to luci....
It looks as though I should be able to connect using
iw wlan0 connect -w ssid passphrase
but can't figure out the correct syntax
No, you can't (that only, kind of, works for WEP, which isn't supported by OpenWrt at all anymore), it doesn't (and never did) for WPA based encryptions, which need more than the kernel can provide without userspace help.
If you don't have luci (installing it might be sensible), you need to configured /etc/config/wireless correctly.
I guess luci is running but don't have any means of using it at the moment, so it's down to getting the wireless options right...Do I really need to set channel, band and htmode? And if not how do I know the correct values?
As for the wifi-iface, is it correct to set network, mode, encryption to wan, sta, wpa?
I understand that I also need to add this to /etc/config/network
config interface 'wan'
option proto 'dhcp'
Is that correct?
Is this a reference to WiFi or configuring your WAN interface?
I ask because:
/etc/config/wireless to setup WiFi, not the network fileP.S. - I was about to send you a private message to ask a question - then I realized I already sent you one the other day. Please take some time to look at it/respond at your earliest convenience.
I was told I needed to amend /etc/config/network so that the wifi interface IP address would be configured by DHCP.
Doing a scan finds the required ssid which shows as
Cell 01
Mode: Master Channel: 1
Encryption: WPA2 PSK (CCMP)
HT Operation:
Primary Channel: 1
Secondary Channel Offset: no secondary
Channel Width: 40 MHz or higher
Should any of these values be incorporated into my /etc/config/wireless ?
I guess 'channel' should be 1 and 'encryption' should be 'wpa2' or 'psk' ...
Where/by whom? *
*This would be the setting:
option encryption 'psk2+ccmp'
*- Please take some time to answer my PM, thanks.
I'm not really familiar with how this particular forum software works. Not sure where to locate PMs.
On the menu - clicking on your B icon in the upper-right corner, a menu will appear - click here:
No worries, I provided all the information regarding your inquires in the post.*
I'm just inquiring so I understand your skill level - you seem to have forgotten things about OpenWrt, and as you've been a Community Member for quite a few years - I was concerned and asking via Private Message.
I hope it helps.
My apologies, I misunderstood that you were attempting to add DHCP client setting to wireless. My bad - as I noted already:
That config should already exist, so it's unclear why you're inquiring.
I apologize for any confusion and hope that clarifies things. I was writing as if you were aware of that information. I hope this provided clarity.
*It says you already read it...
Per your PM, here's a sample STA config:
config wifi-iface 'wifinet1' #<---may differ on yours
option ssid 'upstrream_SSID'
option device 'radio0' #<---may differ in name/band
option mode 'sta'
option key 'xxxxxxxxxxxxx' #<---may differ on yours
option network 'wwan' #<---or use wan, since it already exist
option encryption 'psk2+ccmp'
I noted that there should already be a wifi-device default config, and AP configs, so I hope this helps you setup. I"m not sure what you need exactly, as there should be default wan config (in network) and a default wifi-device settings (in wireless).
I'm still unable to connect so I'd like to confirm my /etc/config/network is setup correctly to enable automatic IP address allocation..
I have an
config interface 'loopback'
config globals 'globals'
config device
option name 'br-lan'
option type 'bridge'
list ports 'eth0'
config interface 'lan'
option device 'br-lan'
option proto 'dhcp'
option ip6assign
to this I added
config interface 'wan'
option proto 'dhcp'
Is this OK?
config iterface
Yes, this is correct for a WiFi-only wan, per my last post - we can:
config wifi-iface 'wifinet1' #<---may differ on yours
option ssid 'upstrream_SSID'
option device 'radio0' #<---may differ in name/band
option mode 'sta'
option key 'xxxxxxxxxxxxx' #<---may differ on yours
option network 'wan' #<---you used wan
option encryption 'psk2+ccmp'
Be sure to delete the default AP mode interface (since Intel doesn't support AP) and remove the option disabled line from the wifi-device block. Check the log for wifi-related errors. Run iw dev and you should have one device of mode Managed. If it has connected to the AP you'll also see the SSID and channel of operation. Channel 1 is in the 2 GHz band so option band should be 2g.
After some time away from my laptop, I'm getting back to where I left off...
iw dev:-
phy0
Interface wlan0
ifindex 5
wdev 0x2
addr 00:21:5c:42:47:75
type managed
txpower 15.00 dBm
The wifi LED is on and iwinfo wlan0 scan includes my wifi router.
My /etc/config/wireless includes a
config wifi-iface 'default radio'
which includes ssid, key and encryption
My /etc/config/network includes
config interface 'wan'
option proto 'dhcp'
I must be close to getting this working. What more do I need to configure?
