Ευχαριστώ για την απάντηση αλλά μου βάζεις δύσκολα. Δεν έχω τέτοιες γνώσεις. Στο φορουμ της Sony βρήκα αυτό όμως και θα το δοκιμάσω.Here is how I fixed my problem
It appears that there are 2 different types of IP addressing, IPV4 and IPV6. IPV6 is said to be more secure because it uses a larger number base than IPV4. Some people say IPV4 is faster, some say IPV6 is faster.
When I go to
Settings
Network
Advanced Settings
Network Status
Check Connection
If the results show that IPV4 passed or failed and IPV6 Passed or failed, then you have IPV6 enabled.
go back to advanced settings
IPV6 Setup
Do you want to enable IPV6?
Respond No.
Thats it.
Now when you check Network connection you will only local ok internet ok, you will not see ipv6 or ipv4. It is now only using IPV4.
