5 GHz dropping

[Andries]

I have new router (joined April 11th) and everything is working fine except the 5GHz band. Discovered this through my LSX II KEF speakers. I need to switch these on/off frequently to reconnect. Checking my router 5 GHz had nothing connected. Most of the equipment switches to 2.4 GHz (like my iphone) but the KEF's are locked to a band.

Slow speed, intermittent dropouts, breaks in the signal or no signal on some or all devices or no internet access might be caused by Wi-Fi interference from other local networks, which can also lead to a permanent reduction in speed. No ISP can be responsible for your local environment, this is mainly a byproduct of the popularity of Wi-Fi.

However, other factors should be investigated first. When this happens, what are the lights showing on the front of the router? Do you have any wired connections & if so, how do they perform?

Generally speaking, the 2.4GHz band suffers a lot more from interference than the much faster 5GHz band, but the 2.4GHz one can sometimes have a better range, but this all depends on your local area.

In other words, I try to help you optimise your Wi-Fi connection. The next stage involves sending out a guide to you to help you get me some important diagnostic results so that I can analyse them for you and recommend changes to your router configuration to solve them.

I only send this out to people who request it.

They work on both bands, but only 1 at a time. KEF recommends 5 GHz for reasons of bandwidth, they also recommend to rename the SSID (to prevent automatic switching) and band steering (if that is the correct term).
Further I have disabled MAC filtering completely and fixed the channel (no auto)..

Hi @Andries 

Do these speakers only work on the 2.4GHz band only? If so, I am puzzled as to why you think that the 5GHz band is dropping.

[Andries]

Hi Keith it's a Sagecom 5364 and the speakers are KEF LSX II, they have advised me to go back to 2.4 GHz to see if the issue persist. I am happy to do that, but it wouldn't really solve the issue of course.

@Debbie-TalkTalk has asked me to help you. First of all please can you tell me the make & model of the router that you are using?

Sorry new on the forum, but found the reply button 🙂

Yes I did previously split as this is a recommendation from KEF.

Basically I alwyas identified the 5 GHz as a separate network to manage the load,

[Andries]

Yes did reset, I've been ongoing experimenting with router settings to get it working (like cancelling MAC filtering) etc. To no avail.
Previous router from UW had no issues.

[Andries]

And split the names into one that identifies as 5GHz (also KEF recommendation).

Hi Andries

Thanks for confirming.

Did you previously split the SSID's on the router?

[Andries]

Sure,  several times. Also cancelled bandsteering (as KEF recommends).
When I looked in the router there was nothing connected this morning (should be 3 devices)

Hi Andries

I'm sorry to hear this.

Have you tried resetting the router? (pin hole reset for ten seconds)
