Wi fi disc

[Laur1 · Accepted solution]

Thankyou for your thoughts licquorice

I thought I'd just post this last message on this subject in case anyone else might find it useful

I have BT full fibre 500. In theory it should be enough to give me good streaming reception on TV even at 2.4Ghz

This isn't the case. BT say the broadband signal is fine, and running a speed test on my laptop using wifi confirms this

I tried changing channels on 2.4Ghz as suggested - made a little difference but not really significant. I'm confident that if I connected the TV to my hub using ethernet it would be fine, but a) I don't have a 15ft Ethernet cable and b) it wouldn't be practical to run a cable diagonally across the room.

So I tried the method I first suggested in this thread and set up my BT disc next to the TV and linked them with an ethernet cable - problem solved. Even the Discovery+/TNT sports (which was previously the worst problem) streams smoothly with no buffering

Which probably indicates the problem is with the WiFi interface on the TV as per my last suggestion or interference at 2.4Ghz.

If you turn off the 5Ghz WiFi on the hub and see if your laptop works ok on 2.4Ghz it will show where the problem lies.

Glad you solved it though.

Just a heads up because I do really get fed up with the knowledge demonstrated in these forums on occasions.

2.4GHz WiFi ch 1-13 max power output 100mW
5GHz WiFi ch 36 - 64 max power output 200mW
5GHz WiFi ch  100 - 140 max power output 1W (1000mW)

Yeah so in reality it's not as straightforward as that, but lest at least get the stupidly basic facts correct!

So with the *right* client on the *right* channel, 5GHz can be more powerful than 2.4GHz in home WiFi.

The other stupidly basic fact is that 5Ghz needs twice the power of 2.4Ghz to reach the same distance.

WiFi isn't just about EIRP
