My Bravia KD-49XD8099 updated the firmware this morning and since then the WiFi drops every 5/10 mins, it reconnects itself after about 30 seconds. It’s driving me mad. I’ve tried a soft reset of the TV. Any ideas how I can sort this please? Just to add this is definitely not an issue with my router or broadband signal, every other device including another smart TV is fine and this has only started since the firmware update. I can’t connect via Ethernet as the route isn’t in the same room as the tv. Thanks for your help.
