I migrated my network from a turris omnia to MikroTik rb4011igs+5hacq2hnd-in.
I have roughly 20 Wifi Devices in my network. Dual band capable modern clients (Smartphones, Macbooks, Thinkpads etc.) but also many Raspberry Pi based systems.
The migration went quiet good, but I am not able to connect 5 Raspberry Devices to the MikroTik setup All have the same wifi module: RTL8191SU 802.11n WLAN Adapter with a r8712u kernel module. All systems operated stable in my old setup. Unfortunately some of them are not easily physical accessible (but the SNR should be good enough to connect).
Other clients (also Raspberry Pi's with the same os + wpa_supplicant.conf, but with a different wifi module) can connect to the same SSID.
Log of a connection request:
Code: Select all
[user@MikroTik] > /log print where message~"wlan4"
19:11:19 wireless,info 00:87:33:XX:AA:BB@wlan4: connected, signal strength -58
19:11:24 wireless,info 00:87:33:XX:AA:BB@wlan4: disconnected, unicast key exchange timeout
1) sync times between station and access point
2) switches between Auth Modes and Encryption Standards: AES CCMP / TKIP etc.
3) modfied group key interval to 01:00:00 / one hour
4) changed channel width between 20mhz and 20mhz - 40mhz
5) fixed channel
6) changed PSK in size and char variation (somewhat freaky)
7) installed three different os versions / versions of kernel modules
No success respectively luck so far.
It is sad, because in general I like the system but I think I have to go back to turris omnia or give ubiquiti a try. Maybe I could use some kind of wired MikroTik device with an wireless module to mesh or uplink the traffic.
To be honest I never had such a situation in a basic WPA2PSK AES CCMP scenario - I already spend to many hours.
Thank you very much in advance!
