Sony Bravia KD43XG7073ASU won’t find 5ghz broadband on wifi

[Dunc1960]

Hi there,

I have recently purchased this TV and although a great purchase I have one issue. I run 150mb hyperoptic broadband and the router runs a 2.4ghz and 5ghz WiFi network simultaneously. I live in a small flat so connect everything to 5ghz for maximum download speeds. The tv can’t find the 5ghz network when I search to connect to WiFi. This is the only time I have had this issue with any device. Generally this is fine but when I try and stream anything in UHD it causes a lot of buffering which is frustrating when I have paid for fast broadband. A direct wire connection would not be feasible as the router is in another room. Is there a way I can set up the connection manually or will it be sorted in a new firmware update?

Thank you for your help

Hi Dunc, 

Welcome to the community.
We'll see if we can find any information about this for you. In the meantime, maybe another community member might have some tips. 

Best wishes,

I suggest you to buy a couple of Powerline devices...

This Sony TV, which is not an Android TV but a Freeview Play one, has only 802.11b/g/n wireless, of which b and g work on 2.4GHz only, and n works either on 2.4Ghz or 5GHz, but not both at once, for which you need 802.11ac.

I read that describing wireless as 802.11b/g/n rather than n alone means that it doesn’t support 5GHz at all but I don’t know how true this is.

I guess your router is 802.11ac, to be able to support both 2.4GHz and 5Ghz at the same time.

If 802.11b/g/n does mean 2.4GHz only, then I think it vanishingly unlikely that the TV could be upgraded to this, as it would need a new wireless card at least, not just a firmware upgrade.

But 802.11n can run up to 450Mbps, theoretically, which is still three times faster than your Hyperoptic can deliver, and so shouldn’t be a limiting factor.

If I were you, I’d run the free WiFi Analyzer program on an Android phone or tablet (iOS devices are no good for this, unless you have a jailbroken one, as Apple won’t allow apps that can do what needs to be done to provide this into their App Store), and see what it shows on the 2.4GHZ band near the TV; is the signal from your router good and strong, are there competing signals nearby, can you perhaps move to a less congested 2.4GHz channel, and so on?

Or, as @Marino.Manolo suggests above, PowerLine Adaptors (Ethernet over the mains) would let you have a wired connection without having to run an Ethernet cable through.

Hi Dunc1960 ,

I totally agree with Royabrown2.

Thank you for the help everyone! Looks like I will be investing in some power line adaptors then!
