Slow wifi and no 5Ghz from Eero 6

[jenny727]

Hi,

I recently (sept 20th) had fibre 150 installed through talktalk, with the supplied Eero 6 dual band mesh router.

After open reach had finished the installation and set up the eero I connected my kindles,phone ect

to it. We did several wireless speed tests and it showed between 147 and 151 Mbps and a 5Ghz connection in the same room as the Eero.

All my TVs, PVRs, Desktop ect are all connected via Ethernet cables and speed tests showed a constant 151 Mbps. The next day however my wireless connection had changed from 5ghz to 2.4ghz on all devices and the speed had dropped massively to between 5 and 15 Mbps and this was in the same room as the Eero. The wired connection still remained at 151 Mbps. Tried disconnecting and reconnecting devices to no avail, still would only connect at 2.4Ghz and slow speed. Tried all trouble shooting tips, turning off 5Ghz, soft reset, ect but all devices still would only connect to 2.4Ghz. Ran two different wifi analizers and neither could detect 5Ghz only 2.4Ghz.

I have been having this trouble for 2 weeks now so Eero has had time to settle down but still no change.

Also if I move out of the room where the Eero is into the next room the speed droops right off.

Could this be a faulty unit or do you have any other suggestions.

I have also heard other people have had this problem and it has been rectified by being sent a Eero 6 pro as this is tri band and has both high and low 5Ghz frequency's as well as the 2.4Ghz.

Kind regard

jenny.

P.S – Before we changed to full fibre we had fibre 35 with talktalk. The dlink router was in the same place and the wifi signal was excellent throughout the whole bungalow and most of the garden.

Thanks Jenny. I don't know why it's changing bands. Does the wifi analyser show all 2.4GHz channels congested?

Hi Chris,

2x kindle fire HD 10,  2x kindle fire HD 8, Roku's 4k streaming stick and lenovo laptop.

All the above show high speeds when connected to the 5GHz channel 42, control channel 36

but when eero channel changes to 5GHz channel 155, control channel 149/153 they all connect 

to 2.4GHz and slow speeds and poor coverage. 

Why is the 5GHz channel changing at the same time every day. If it remained on 5GHz channel

42, control channel 36 it would be perfect.

kind regards

Jenny

Could I just ask which device you are running the speedtest on and getting the slow speed test results?

Hi,

I have read the Eero 6 pro is tri band and has both high and low 5Ghz frequency's as well as the 2.4Ghz

and cures this particular problem. do you know if this is correct.

Kind regards 

Jenny.

Hi @jenny727 

Alas yes, you are right. I'll have to ask TalkTalk for you, if you could try a different router.

[jenny727]

Hi Chris,

As far as I am aware you cannot change the channels on a Eero 6.

If I am wrong and you can, could you please tell me how to do this.

Kind regards

Jenny.

Hi Jenny,

Could you give Keith's suggestion a try and let us know how you get on

Hi @jenny727 

The problem here is that not all Wi-Fi adapters in your various devices will not support channels as high as 155. Try changing the router to channel 36 for maximum compatibility.

Hi Chris,

Firstly thank you for sending the new Eero to me.

Changed the Eero's over using the app and everything was looking good.

All wireless devices connecting to 5GHz and good speeds recorded on

speed tests. Wi-Fi Analizer also detected strong 5GHz signal.

Unfortunately the next morning all my devices were back on 2.4GHz and

running slow speeds. Looking at the Wi-Fi radios page in the app it is clear

to see the 5GHz channel and control channel changed at about 03.00 am.

When devices do connect to 5GHz the Wi-Fi radios page in the app shows :

channel 42

control channel 36

when devices will not detect 5GHz Wi-Fi radios page in the app shows :

channel 155

control channel 149/153

Tried unplugging for 30 mins, soft restart etc but nothing would bring back the

5GHz signal. I then tried swapping Eero's again and everything worked fine again until

about 03.00 am when the channel and control channel changed again. Why would

it do this? and why at the same time every day?

I have sent three screenshots to show this.

Kind Regards

Jenny.

OK thanks Jenny 🙂

Will be in touch when we have set it up.

Hi Michelle

Sorry been away on a short break so only just got this. That would be great if 

you could send a replacement to see if it resolves the issue.

Kind Regards 

Jenny

Hi jenny,

I'm sorry for the delay. This would be a like for like swap. Would you like us to send this for you? We would also send a router returns bag so that one of the eeros can be returned.

Thanks

Michelle

Hi Karl

Unsure if you received last post as I have received no response or are you 

just sending a different Eero to try to see if this cures the problem.

Thanks and kind regards 

Jenny

[jenny727]

Hi Karl

Thanks for your reply. Did you mean swap it for Eero 6 pro as this is tri band as others have said

this cures the problem or do you mean like for like.  As you are the expert I will go along with whatever

solution you think will best solve the problem. 

Kind Regards

Jenny

Hi

Would you like to swap out the eero and try another  ?

Thanks  

Karl.

Hi Michelle,

 Powered down for forty minutes to be sure but after restart still exactly the same. 

Disconnected and reconnected kindles phones ect but when reconnected still only connecting

at 2.4Ghz and slow speeds as described earlier. Ran wifi analizer again and still not showing 5Ghz .

All wired connections still remain constant at 151 Mbps . 

Kind Regards

Jenny
