Hi,
I know WEP is frowned upon and enverone should be using WPA. And my hostapd AP is working with WPA clients. However, I would like to alow some older clients that can only “talk” WEP to connect.
All my attempts so far have failed! Can anyone point me in the right direction?
The hostapd.conf file comments suggests that hostapd can support WEP. There are no contraindications or flags that I can find in the defconfig file that suggest that a WEP module needs to be complied-in to the final make.
Regards, Martin
Martin,
which errors do you see? Can you post your hostapd.conf file?
Uwe

Martin,
looks to me the WPA part isn’t working, it doesn’t even get to play with WEP.
Uwe
Hi Uwe,
Thank you for your thoughts. Can you expand a little more?
From a complete novices point of view, I see things a little differently: As this line is at the server (hostapd) end…
wlan0: STA 00:02:2d:29:d5:88 IEEE 802.11: No WPA/RSN IE in association request mgmt::assoc_resp cb
… is it not saying that “I can not see any WPA information in the association request from the client”?
Which is perfectly true. There is no WPA from the client. The client can only talk WEP.
However, when a WPA or WPA2 does come along, it can connect quite happily to this access point.
But why can’t hostapd fall-back to a WEP module or whatever is need to support the WEP-only client?
Puzzled, Martin
Martin,
okay, I didn’t realize it does work with WPA. I’m sorry, but I am out. I have no hardware supporting hostapd so I cannot try it myself.
Uwe
Hi Martin,
I’m very new here and I’m not an expert either but looks like your configuration is not correct. You don’t need to give all the keys (key0, key1, key2, and key3) like that. The wep_default_key determines which wep_key you’re going to use, and the value is from 0 to 3. For example, if you set wep_default_key=0, you need to use only wep_key0.
Also, you cannot enter the key string the same length for all the keys. You need to use it in accordance with the valid key length, i.e. 40-bit, 104-bit, and 128-bit.
The following config works fine in WEP option for me. Note the wep_default_key and wep_key1:
interface=wlan0
bridge=br0
driver=nl80211
ssid=testing
channel=1
hw_mode=g
auth_algs=3
ignore_broadcast_ssid=0
wep_default_key=1
wep_key1="abcde"
wep_key_len_broadcast="5"
wep_key_len_unicast="5"
wep_rekey_period=300
The key string should be in one of the following formats:
wep_key0=123456789a
wep_key1="vwxyz"
wep_key2=0102030405060708090a0b0c0d
wep_key3=".2.4.6.8.0.23"
Hope this helps!
