  1. Oh well, same issue with the powered hub, then tried with a different driver (https://github.com/pvaret/rtl8192cu-fixes) sudo apt-get install dkms git clone https://github.com/pvaret/rtl8192cu-fixes.git sudo dkms add ./rtl8192cu-fixes sudo dkms install 8192cu/1.10 sudo depmod -a sudo cp ./rtl8192cu-fixes/blacklist-native-rtl8192.conf /etc/modprobe.d/ sudo reboot and at next boot had the wifi up and running > lsmod Module Size Used by mac80211 358429 0 mali_drm 2732 1 drm 178255 2 mali_drm mali 123208 0 ump 29379 3 mali 8192cu 624560 0 > ifconfig wlan1 Link encap:Ethernet HWaddr 00:13:ef:62:0a:ee inet addr:192.168.1.4 Bcast:192.168.1.255 Mask:255.255.254.0 inet6 addr: fe80::213:efff:fe62:aee/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1492 Metric:1 RX packets:18910 errors:0 dropped:1173 overruns:0 frame:0 TX packets:34687 errors:0 dropped:2 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:15112303 (14.4 MiB) TX bytes:71589296 (68.2 MiB) > iwconfig wlan1 IEEE 802.11bg ESSID:"WESTEROS" Nickname:"<WIFI@REALTEK>" Mode:Managed Frequency:2.437 GHz Access Point: 00:1A:E3:B8:EA:30 Bit Rate:54 Mb/s Sensitivity:0/0 Retry:off RTS thr:off Fragment thr:off Encryption key:****-****-****-****-****-****-****-**** Security mode:open Power Management:off Link Quality=100/100 Signal level=92/100 Noise level=0/100 Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:0 Invalid misc:0 Missed beacon:0 > cat /proc/net/wireless Inter-| sta-| Quality | Discarded packets | Missed | WE face | tus | link level noise | nwid crypt frag retry misc | beacon | 22 wlan1: 0000 100. 97. 0. 0 0 0 0 0 0 > iperf -c 192.168.1.22 -p 20 ------------------------------------------------------------ Client connecting to 192.168.1.22, TCP port 20 TCP window size: 20.9 KByte (default) ------------------------------------------------------------ [ 3] local 192.168.1.4 port 39951 connected with 192.168.1.22 port 20 [ ID] Interval Transfer Bandwidth [ 3] 0.0-10.2 sec 7.12 MBytes 5.88 Mbits/sec > iperf -c 192.168.1.22 -p 20 ------------------------------------------------------------ Client connecting to 192.168.1.22, TCP port 20 TCP window size: 20.9 KByte (default) ------------------------------------------------------------ [ 3] local 192.168.1.4 port 39952 connected with 192.168.1.22 port 20 [ ID] Interval Transfer Bandwidth [ 3] 0.0-10.2 sec 21.9 MBytes 18.0 Mbits/sec speeds are quite inconsistent, didn't go over 20Mb/s even with the AP at 4 meters, but that's not a big concern for now, maybe it only needs some tweaking, but at least it is working! Here is the dmesg of the successful association: Thanks everyone for helping me solve this problem.
  2. Big update here, after obtaining access to the logs during system crash it seems to be caused by a kernel bug. I'm not qualified to solve a kernel issue, can't even understand the error report, so I'll post it here in case someone want to take a look at it. Also is there a place where I should report this? Who is the right recipient for a kernel bug?
  3. ahhhh spot on! It seems that in my lazines I just copy-pasted the original line and forgot to add the sneaky S... Thanks to both of you, I can now get back to my original wifi issue (the never ending cycle, fix one, break two).
  4. So, I've hooked up the OPi via ssh and changed the boot.cmd file as follow #setenv bootargs "console=tty1 root=/dev/mmcblk0p1 rootwait rootfstype=ext4 cgroup_enable=memory swapaccount=1 panic=10 consoleblank=0 enforcing=0 loglevel=${verbosity}" setenv bootargs "console=tty0 root=/dev/mmcblk0p1 rootwait rootfstype=ext4 cgroup_enable=memory swapaccount=1 panic=10 consoleblank=0 enforcing=0 loglevel=6" then compiled boot.scr sudo mkimage -C none -A arm -T script -d /boot/boot.cmd /boot/boot.scr Image Name: Created: Thu Aug 25 00:28:49 2016 Image Type: ARM Linux Script (uncompressed) Data Size: 2442 Bytes = 2.38 kB = 0.00 MB Load Address: 00000000 Entry Point: 00000000 Contents: Image 0: 2434 Bytes = 2.38 kB = 0.00 MB and lastly disabled login on tty0 sudo systemctl disable serial-getty@ttyS0 After a reboot on the uart console I got the usual booting messages then nothing else, no login prompt (as excepted) but also no dmesg output. I think I may have modified the boot.cmd file incorrectly, it's the first time messing with these settings, sorta flying blind here.
  5. I tried to use dmesg -w but all I get is the normal dmesg output, it doesn't wait for new messages.
  6. Hi there, while trying to solve the issue with OPi PC and rtl8188 (thread link) I managed to get console on the UART interface, nice feature considering my networking issues, btw is there a way to output the kernel messages (dmesg like) to the UART console in real time? I'm asking cos the issue that I'm trying to fix involves system freeze + automatic reboot and I would like to see the logs during the event. I already tried to mess with printk, but it's very likely I've done something wrong.
  7. For both the devices this is what Windows has under the "Hardware Ids" tab: USB\VID_0BDA&PID_8176&REV_0200 USB\VID_0BDA&PID_8176 When connected they are automatically recognized as Realtek RTL8188CU Wireless LAN 802.11n USB 2.0 Network Adapter.
  8. Little update: Today I got another usb module with rtl8188 and the problem persisted I even swapped the power supply with a 24W rated brick and the cable with a beefier one with no success. Then I tried connecting an rtl8187 module and it was working out of the box with no issues. For various reasons I can't use this adapter with the orange pi (it's a 500mW RF output adapter with a bulky enclosure) so I would really like to make the 8188 models work. Details of the modules loaded with the 8187: > lsusb Bus 003 Device 002: ID 0bda:8187 Realtek Semiconductor Corp. RTL8187 Wireless Adapter > lsmod Module Size Used by rtl8187 48812 0 eeprom_93cx6 2375 1 rtl8187 mac80211 358429 1 rtl8187 mali_drm 2732 1 drm 178255 2 mali_drm mali 123208 0 ump 29379 3 mali Waiting for suggestions on what to try to stop these reboots, also hoping that the op solved the issue somehow and will report back.
  9. Same problem here, bad password issue with a fresh install, then instant system freeze when hot plugging after following this tutorial for opi one -> http://forum.armbian.com/index.php/topic/1237-tutorial-opi-one-wireless-success/ Some info: > uname -a Linux orangepipc 3.4.112-sun8i #14 SMP PREEMPT Tue Jul 5 16:28:14 CEST 2016 armv7l GNU/Linux > lsusb Bus 003 Device 002: ID 0bda:8176 Realtek Semiconductor Corp.
