New Hub, new problems.

Thompson218 — Sat, 20 Jul 2024 19:03:07 GMT

This is since getting a new Smart Hub 2 to facilitate the move to IP phone lines.

I'm getting pixelation when watching Netfix through the App on my Sky Q box. It worked fine with the Hub it replaced.

Watching Netfix through the App on the TV it works fine.

The Sky Q box works on 2.4GHz.

The TV works on 5GHz.

My view is that BT have caused the problem by changing my Hub. The Customer Advisor I spoke to ran a range of tests and rescanned the WiFi channels like a pro, but the problem persists. They say I need to speak to Sky!

So BT give me a new Hub, cause me to have a problem but refuse to help.

What do I do?

SkyQ uses channel 36 so make sure you change the hub to 44/48. I would also use WiFi analyser on phone and see channels I use near you then select a free or less congested channel for 2.4ghz

Personally I always change the new hub SSID and password to that of old hub and that way my WiFi devices connect as if nothing had changed

Thank you, but I don't quite understand your answer.

I've set 5GHz to channel 36. I don't know what you mean by setting the hub to 44/48?

I've used WiFi Analyser and it suggests using Channel 3, 4, 5 or 6 for 2.4GHz but the only options in the Hub Admin App are Smart, 1, 6 or 11. I've set it to 11.

Is there anything else I can because the problem is still happening.

Thanks again.

you need to set the hub 5ghz network to something other than 36 as that is used by SKYQ so try changing to 44/48

Oh, sorry, OTHER than 36. I thought it needed the same. I've changed it to 48.

Is there anything I can do about the lack of suitable options on 2.4GHz?

The problem with picture breakup is still evident even with the suggested changes in place.

So what now?

Could the new Hub be faulty? Is there a better hub? Are there any other configuration options? Can I go back to the old Hub and not have the IP phone - which we don't need?

with the SH2 you can only select the wifi channels which you see are available. it seem unlikely hub is faulty just your 2.4ghz devices are having problems connecting. this is not a hub problem but a device problem but try turning off the 5ghz wifi in hub and then see if the 2.4ghz devices connect. if they get connected then re-enable the 5ghz in hub

"...... just your 2.4ghz devices are having problems connecting. this is not a hub problem but a device problem"

One device, namely my Sky Q box and the installed Apps, all of which worked fine with the old hub.

did you try turning off the 5ghz wifi in hub as some devices have problems connecting with the hub 2.4/5ghz wifi and often turning of the 5ghz helps the devices connect to 2.4ghz you may need to restart your SKYQ box before trying

Turned off 5GHz, restarted Sky Box and still getting the occasional pixelation.

Stumped.

I believe what imjolly is suggesting is that the Sky Q box forms part of their own mesh system and transmits on channel 36. If memory serves, that cannot be changed. This will be interfering with/interrupting the SH2 and the delay caused is behind the pixelation. The SH2 needs moving to channel 40, 44 or 48 to avoid this.

As far as 2.4GHz goes, to put a lot of history into a nutshell, when wireless first launched it was an industrial thing configured by techs that knew what they were doing. Then the home market took off and world, brother and dog got involved.

In fact, the only channels that do not overlap with other channels are 1, 6 and 11. In a crowded environment you are better to share a channel with your neighbour. There is a mechanism in place that allows two wireless units on the same channel to cooperate and share the channel, taking turns. If your neighbour uses, say, channel 6 and you use 8 they overlap and interfere but can’t hear each other clearly enough to cooperate, making matters worse for both parties. Consequently, you should stick to 1, 6 or 11 even if the other channels are available.

You will notice that at 5GHz the channels are already spaced four bands apart, 36, 40, 44 ,48.
