I would like to share an issue that seemed solved in the past.
When I plug my Wifi dongle, it seems recognized, but for obscur reasons is quickly disconnected (extract of dmesg as “proof”) Extract from dmesg
What I’ve tried yet :
Tried with several power supply
Tried to customize config.txt (with max_usb_current=1)
Tried to update apt/sources.list
$ cat /etc/apt/sources.list
deb Index of /raspbian jessie main contrib non-free
deb http://apt.osmc.tv jessie-devel main
I’ve tried with new PSU, lightning bolt disappear but same problem.
so :
1st : the first PSU I used is not in cause
2nd : the long cable I used drains some power but not that much
3rd : I’ve tried with an other PSU : no more lightning bolt, but same problem with the WIFI key
4th : I’ve tried with an other WIFI stick (D-Link DWA-140 to be precise) : it works.
In my opinion : there is still some issue with that realtek chipset :
USB: 0BDA:8176 Realtek Semiconductor Corp. RTL8188CUS 802.11n WLAN Adapter
That issue is not specific to osmc, but seems to realtek in linux…
I don’t have the resources (time) to help compiling the specific module for that wifi stick, but I can test and help if wanted
