Fibre dropping out after 5 minutes

[#1]

Hi I am new to Plusnet and fibre was dropping out every 5 mins then saying password was wrong! Have tried everything but disabling 5Ghz has worked-do I need this? Will it impact on my speed please?

@VYEATS if all your devices are only 2.4ghz compatible , then No. However 2.4ghz is limited to around 100Mb real world speed, so if you've got devices capable of using the 5ghz band then they will suffer the reduced speed.

This https://www.intel.com/content/www/us/en/products/docs/wireless/2-4-vs-5ghz.html gives a good explanation

Welcome to the forums, @VYEATS . What you have said above sounds very strange. If your connection was dropping out 'every 5 minutes' that suggests a network issue, Saying the password was wrong suggests your username/password combination was still set to <setup@plusdsl.net>, rather than <youraccountname@plusdsl.net>, and disabling 5Ghz is a slight red herring - that will have no bearing at all.

Hi I checked that, it was definitely my username not setup@

What happens if you re-enable 5Ghz?

@jab1 

My reading is that the network is up and fine as it works when devices are connected via the 2.4GHz band. The problem is therefore  the  rejection of the 5GHz SSID password, presumably an incorrect flag being raised by the synchronised 2.4 and 5GHz bands.

Thanks, @Baldrick1 . Hadn't thought of that, but AIUI, both bands use the same P/W?

[#9]

I’m too scared to!

Ok I’ve turned the 5 g back on and downstairs devices still working but upstairs ones can’t connect to internet

[#11]

Strange. What devices do you have upstairs, and how old are they?

[#12]

Amazon fire stick old version and a HP pc 2 years old

[#13]

What message do you get on the PC? I suspect the Firestick uses 2.4Ghz only. Did these items connect whilst the 5Ghz was turned off?

[#14]

Yes they worked on 2.4

[#15]

In that case, and providing you are on FTTC and not Full Fibre (FTTP), my suggestion is to turn the 5Ghz off.
