Problem with Wi-Fi connection after update to Oreo 8

[Shiyar]

Auf KD49 XE8005...... Today I have updated Oreo 8 in Germany but after the update there is the problem of connecting to the Internet after connecting with 30 seconds or more automatically interrupts the connection and does not connect again, although I have reset the factory and the problem remained ....... Please have a solution to the problem ?

There are reports about WiFi issues after the Oreo all over the web. I have been reporting about those for months already as I have been one of the early adopters who installed over USB. But as usual, Sony does not listen...
