Try changing the DNS to a public one (like 8.8.8.8 or 8.8.8.4)

Hi Rob,

The details I posted were DHCP, how it has always work.

When we tried fixed IP, we  used the two google DNS server IPs as suggested 😞

thanks

I assume you tried but it is not working in any case even if you kudoed me....

[ancaise]

kudos was reading and replying

even tried setting google dns as default in the router with no success.

tried connecting to iphone hotspot which nearly worked but once connected, just rebooted itself on every connection until i turned it off.

looks like a long and lengthy support call.. doh!,,

Hi,

   Did you get a response and a solution to this issue please? I've had this issue on my XF9005 since the Oreo update where wifi keeps dropping and I'm looking for a solution.

Thanks

hi, apologies, thought Id posted my resolution to all the posts id replied to.

If you have other routers / extenders on the same network, it is worth unplugging / powering / disconnecting them all for a test.

Does your TV work when hard wired direct to the router?

------------

The issue is now resolved.

There was another router on the home network, which been there for 2 years! with DHCP turned off but used to extend the wireless to a downstairs room. We were using a wired connection and both routers were connected to the same network switches.

The TV was definitely connecting to the main router as we could see it in the logs. It then briefly got an internet then disconnected.

After the software update, something must have changed that is now checking around the network and found the other router as it was delivering the same gateway address.

As we can recreate, happy to run any traces / logs / SDK traces for Sony if required.

This is resolved for us now, thank you for your time.

Regards

Andy
