Hello. I have a VIM2. Wifi was working OK, but recently it started to work only sometimes, and now it does not work at all. In Linux, there is no wlan0 interface, and in Android wifi remains turned off and you cannot turn it on.
I don’t think the router has anything to do here. As I said, the wifi interface is not even present, as if it did not exist. Please look at the console logs in the link I attached, there is some error in bringing the interface up.
Anyway, thank you for trying to help.
If this was happening on my VIM2, I would clear the eMMC and then run an Ubuntu from SD card. If I could not get a response from WiFi, I would lean towards hardware issue.
But I agree with others that you should @ one of the Khadas Team.
My VIM3 has no antenna connected, WiFi option in OS still active. I do not use it, but it still works inside OS. So I do not believe antenna connection would stop OS from seeing WiFi module.
Yes, they are part of it, I just do not believe it would cause WiFi module to be unavailable to the OS. Bad antenna connection will cause poor performance, but I that is not the user’s issue.
Yes, we are talking VIM2, this I know, but similarities of this nature will be common between devices. I mentioned VIM3 as an example of no antenna connected to illustrate it would not deny OS access to the module…in any VIM model.
Of course, WiFi should not be used without antenna.
@Vladimir.v.v It’s OK, I already unmounted and unplugged the antennas, and plugged them back, but it didn’t help. Of course, a bad antenna connection could cause some short in the device, or something alike, but looks like this is not the case
