If I recall correctly, it was on 9.3.6,but i obviously have no way to verify that since it doesn’t connect at all.
Just did a factory reset, didn’t solve anything.
I also tried to disconnect everything form my router and connect directly to it (my grobo usually connect to the range extender since they don’t receive the 2.4ghz signal where they’re located, didn’t solve anything either.
Also, I can ping the IP adress of the grobo at all time, so I’m assuming it struggle to connect to the internet, not the wifi. it still doesn’t make any sense since my connection has been perfectly fine lately.
I must say, the whole process of investigation the issue is very tedious and annoying, without any meaningfull way to properly see what the grobo is trying to do.
