Morning,

Asking on here before biting the bullet and calling BT.

Situation:
New build (thin walls!)
Less than 10 devices

Have the latest home hub I believe - 6?

Don’t have ‘complete WiFi’ with the discs.

Speed isn’t normally an issue.

Big concern is keep dropping out on phones, iPads throughout the day and whilst on things like FaceTime?

Have taken off auto settings for channels. Split the channels for 2.4ghz and 5ghz. Hasn’t solved the problem so far.

Any other ideas before I do give them a ring?

Cheers

Have you got anything on a wired connection to be able to check if it's the broadband going down rather than the wifi?

Could also be interference but you changing the channels should have helped there, worth sticking WifiAnalyser or similar on phone to see how busy different channels are.

you say you've split the channels - have you taken the opportunity to move things to 5GHz as much as possible?

Is the situation worse as you get further away from the router - are the more distant rooms flakier?

It's a new build - how many near neighbours wifi can you see?

2nd the advice of look at wifi analyzer - remember for 2.4GHz anything other than 1, 6 and 11 is unlikely to be helpful.

Nothing on wired connection unfortunately.

Will take a look at WifiAnalyser!

Yep, put just the phones and laptop on 5ghz to start as those the ones we wouldn’t want to drop out. No improvement thus far.

Not worse when further away - still drops whilst close by as well as on the top floor - no correlation.

Will take a look at others later but not so many on BT from memory - perhaps there’s good reason for that...

If you have a desktop Mac, it has an analyser built in.

In terms of other networks:



Good, bad, indifferent?

Thanks for this.

Have enabled and will keep running for a while.

Cheers.

Holy Pope on a rope!

We had one of the BT Hub5 (I think) and it was pants at keeping 2ghz agile, we separated the channels in the Hub browser and named them whatever2ghz and whatever5ghz and logged anything not hard wired onto the 5ghz. BT routers also pump out a free wifi.

Ended up bining it for a Netgear. But I had exhausted all avenues first, BT said it must be my iDevices, they would not admit the router had form (according to forums, some were good out the box, some bad).

Apols if teaching granny to suck eggs, casual user myself not an expert.

Assuming you mean you have a Mac desktop?

Turn wifi on. Press Alt and click on the WiFi.

Click Open Wirless Diagnostics (don't do any more with that window!)
Top bar



Click Window

Click Scan

That will give you all the wifi channels your Mac (not necsariily the phone) will be picking up and what frequencies and what channels.

You're not - I was doing it wrong - thanks for the pointers!

Alas a little stuck here, these are the results:




But this is the channel choice on BT?

I suspect that the Mac uses a system that will include more than the BT router, certainly mine suggest one that my router does not use? I thought 5g didn't go far through walls, seems a few on there?

My local, edited out base names etc. A few base stations have dropped off, they are not broadcasting SSID I suspect so may be a few more not being reported. For my 5g on my nether, if I suspect there is an issue, I pick one away from the ones the Mac shows me.


Edit. Something tickling my memory on UK specific frequencies, I assume the router will be that?

If the devices are each dropping wireless connection at different times from each other (rather than all losing connection at the same time) it may be that they are dropping when trying to renew their leased IP.

If this is the case, I'd try disabling DHCP (if using it) and assign each device it's own fixed address, and then see if the issue still occurs.

I am in a similar environment to you (BT, new build, around 10 connected devices over WiFi) and don't have any connection issues except for the TV, and I think that's the TV at fault. We have a three story house and the router is on the ground floor, and we still get a decent signal on the second floor.

It's also worth checking if any of your devices log. If so, this would be useful as it would help you understand why they are dropping the connection.

Finally, I think it's definitely worth checking if the connection is stable on wired, as it will help you understand whether this is an issue with the whole network or just the WiFi.

Attempted the disabling DHCP and frustratingly now can't connect to anything - have had to login via BTWIFI.

Not able to get the home hub admin settings up under: http://192.168.1.254 either.

Not going well. smile

What do you need to do is disconnect one of your devices from the wifi and reconnect but use the advanced/more options/manual method on the dveice to set the following:

IP: 192.168.1.XX (XX can be any value between 1 and 200, so e.g. 192.168.1.62)
Subnet mask 255.255.255.0
Gateway 192.168.1.254
DNS: 1.1.1.1 or 1.0.0.1

Does that work?
