separating 2.4GHZ from 5GHZ

[Anonymous]

So. We recently got Sky Broadband (again) and have been playing with SSID names and passwords and noticed our router is running a synched bandwidth. Now, exactly how can i safely separate the two from each other? Will it cause everyones connection to have issues, like (device: unrecognized SSID)? Will (after the split) the SSID's or wifi names be ********_2.4GHZ and ********_5GHZ or something? Can i set a password for each? Also, i run an AC 1200 wifi range extender, how can i introduce the extender for best results after a split?

When you desynchronise the two bands, you'll need to manually adjust the name of one of them so that you can tell them apart. Adding 5G or something similar to the end of the 5GHz SSID would be sufficient. You'll then have two completely separate wifi networks and can assign a different password to each, if you wish. If you leave the 2.4GHz settings as is, and change only the 5GHz settings, there will be no impact on the devices currently connected to that network. Can't comment on your extender, I'm afraid.

I've been trying to do this like it says in ComputerActive since bloody Saturday. Desync them, change name, apply, logout (if it lets me) chaos. Ethernet lead & sat on the stairs like Kermit's nephew, putting it all back to normal. I've given up.  Mind, it's taken me twenty mins to find 'reply' on here..

@Jason210669 it really is not difficult but first if you have Sky Q tv boxes do not separate the bands unless you have a device that requires it as it can reduce overall speed. 

If you have to separate the 2 bands ideally use a laptop or PC connected by ethernet. Type 192.168.0.1 into a browser. Hit return when the interface loads then click on Wireless you will be required to log in for most hubs the details are the user is admin and the password is sky (no capital S) the very latest routers the admin password is the wifi passcode printed on the label.

When the wireless page loads untick the Synchronise box and edit one of the two SSIDs so you know which is which. Then click Apply. The hub will re-start which takes up to 5 minutes so be patient. On an ethernet device you can log back in again and check the pages. On a wireles device you will probably have to reconnect as the wifi networks have changed. Pick the band you want and enter the passcode then use the browser. If you muck it up press and hold the reset pin until,the lights flash and when the hub restarts it will be back to its factory settings.

For sure, thanks, I'll try again. But that's more or les what I'm doing..

hi, 

I have split my hub as per these instructions because a 2,4ghz network is needed for two smart devices we have. i read somewhere that you may want what was described as 'high-demand' devices to operate on a different frequency to your smart devices and it gave an example of TVs. I just want to make sure I understand, woud we re-set up TVs then to the 5ghz network? And what other devices would be considered to be 'high demand'? Would that include ipads, phones etc? 

Thank you

The differences between the 2.4GHz and 5GHz bands, are that the 5GHz band is faster and the 2.4GHz band has greater range.

So devices which use a lot of bandwidth like streaming or downloading tv would be faster when connected to the 5GHz band. Devices which don't use much bandwidth like printers and smart,devices (lamps, smart plugs, smart radiator valves etc) will be ok on 2.4GHz.

I successfully separated the 2.4 Ghz and 5Ghz signals on my new SkyQ router but did it mainly in the interest of curiosity. 

Not sure what advantage one gains by having the 2 different WiFi hotspots. 

Nor whether it makes a difference if they are split into two.

Why does Sky feel this is usfeul ?

My home security hub (Z wave) is connected to the router via ethernet cable, so I presume it makes no difference to that system that whatever WiFi sytems are in operation - someone correct me if I'm wrong.

Some WiFi devices, particularly IoT hardware, get confused by seeing two different bands offering the same SSID, and end up not connecting successfully to either, or perpetually jumping between them.  Being able to split and rename them is the solution for this, and so it's a feature offered on most wireless routers and access points.

Having had my Sky broadband connection split(2.4GHZ/GHZ) on the never ending amount of times Sky Q loses it's connection with miniboxes(3) when resetting the miniboxes it defaults to the wrong wifi 🙄 I'm not an expert in Sky miniboxes but, would love to know how to change the wifi Sky uses.

Any help greatly appreciated 👍

This is why I haven't bought a smart bulb yet. Not going to separate my WIFI and cause problems with the Sky Q mesh network because automation technology isn't smart enough to distinguish between a 2.4GHZ from 5GHZ network.

In many cases, it helps to split the frequencies only to get devices initially connected. Once they're connected, they can be re-synchronised.

Hi

My son has a vavarium that required wifi access, however there where lots of issues connecting the app/vivarium to the wifi. I was adviced to seperate the 2.4 and 5ghz as the components in the vivarium would not function correctly with dual band wifi. I have separated them, the vivarium and sky etc work fine. However the major issue is that my iphone/laptop is now struggling to connect and slowly loads web pages etc, im constantly juggling between the 2 frequencies, often just switching the wifi off as its now impossible to play video streaming on the device and use 4G.

Any advice on what to do, it seems ive solved one issue but now created another problem

Now you've connected the devices that were having trouble connecting when the 2.4Ghz & 5Ghz signals were synced you should be able to put everything back to normal without causing issues with your sons app/device.

I've tried to separate the two channels but it keeps telling me I've got the name and password wrong
