Eero WiFi

spaarks11 — Thu, 13 Mar 2025 12:40:10 GMT

I am on 150Mbps full fibre with VoIP. Using an Eero 6 router.

Sometimes I am getting the full 150Mpbs, but the other half of the time it is down to 40-50Mbps.

The line speed (at my ONT) is steady at 150Mbps.

I have spent hours on chat with tech support, but the problem is unresolved.

I notice that the eero does not seem to auto select a quiet frequency. There is only one strong interfering signal (from my next door neighbour), which is on Ch1 and Ch36. My Eero sits right on top of these channels! Not always on 2.4GHz, as the interfering signal is frequency-agile and often moves away from my eero.

There are a few signals on 2.4Ghz but apart from one they are low amplitude.

5Ghz is almost empty apart from the next door signal.

Any suggestions would be welcome.

Hi @spaarks11

@Debbie-TalkTalk has asked me to help you. You have obviously used a WiFi analyser, please can you PM me (to preserve your privacy) screenshots from it? Not knowing which one you are using, I need to see as a minimum these views:-

AP view

2.4GHz channels

5GHz channels

Signal strength/time graph having run for 5 mins.

I also need to know your SSID (WiFi network name).

Thanks @KeithFrench 🙂

Thanks for stepping in. How can I PM you?

My SSID is Iolar.

To elaborate a little. On 2.4GHz Eero seems stuck on ch1. However next door Sky signal is agile and often moves to ch11.

Eero has a 40MHz bandwidth on 2.4, considered to be anti-social but prob doesn't matter in this quiet environment. The other signals are 20.

On 5GHz Eero is stuck on ch36, Sky is too. I assume Eero will prefer 5GHz, as there is only one single block wall between Eero and all my rooms.

The only strong interfering signal is from Sky next door, the other signals are from two floors down.

My speeds are half the time 150Mbps and half the time around 40Mbps· There is never anything in between, which suggests to me it could be switching channels, or bands.

My network is lightly loaded except at weekends when there are 3 tv's streaming and games. Otherwise streaming from 1 tv late evenings, one or two mobiles, two security cams, a weather station, and a PC.

I will PM the screenshots once I know how to PM you.

I am currently waiting on a complete set of screenshots from one WiFi analyser. So far, I have only received a mixture of information from two different analysers.

Hi @spaarks11 @Debbie-TalkTalk

Strangely, in the 2.4GHz band, the eero selects to use 40MHz channel bandwidth; it should use 20MHz. In addition to this, it would also be much better on channel 6. I have never seen an eero behave like this, so I can only presume that one of these is the culprit:-

Something near the eero is interfering with it.
The eero needs a hard reset
The eero is faulty.

Taking the easiest first, please can you describe to me roughly where in your property the eero is located?

Is it shut away in a cupboard or out in the open?
How far off the floor is it?
What electronic equipment, large metal objects, glass or water tanks etc are around it or in line of sight with your devices?

Please feel free to PM me with the answers if you prefer.

Once I know the location information, I will make a recommendation based on that.

Apologies for any delay in responding - I am having difficulty connecting to Community.

The Eero is in the open in the hallway, sitting on top of a cabinet and about 1m off the floor.
There are no devices nearby apart from the ONT and VoIP adaptor.
There are no large metal objects or water tanks nearby.
There are no electrically nor wirelessly noisy devices nearby.

Over the past few weeks I have reset the Eero several times (hold bottom button for 20 secs until status light blinks).

Meantime, do we have enough info to proceed your item 3. - to changing out the Eero?

I am away from home at present but will be back this week.

Thanks

I don't think there is any other option then but to get it replaced. I will ask TalkTalk to do this for you. They will hopefully pick up my request tomorrow.

Debbie-TalkTalk — Mon, 17 Mar 2025 08:31:32 GMT

Thanks @KeithFrench

Hi @spaarks11

Are you happy for me to send a replacement eero?

Re: Eero WiFi

Debbie-TalkTalk — Wed, 19 Mar 2025 12:22:56 GMT

Thanks for the Private Message @spaarks11

The eero is on its way 🙂

Re: Eero WiFi

spaarks11 — Wed, 19 Mar 2025 12:34:55 GMT

TalkTalk is charging me £89 for the replacement Eero. I don't accept this because the replacement is to fix a faulty connection.

Re: Eero WiFi

Debbie-TalkTalk — Wed, 19 Mar 2025 12:35:56 GMT

Hi @spaarks11

Please see my Private Message, there will be no charge for the eero I've ordered, please disregard the email received.

Re: Eero WiFi

spaarks11 — Mon, 24 Mar 2025 16:40:31 GMT

Replacement Eero received and installed. Thanks.

The bandwidth on 2.4GHz is 20MHz, as it should be.

There is still an issue with the router on 5GHz sitting on the same channel as the only other interfering signal on the 5GHz band but I suspect this is a systemic issue, and not with my Eero itself.

Re: Eero WiFi

spaarks11 — Mon, 24 Mar 2025 16:49:48 GMT

Received and installed the new Eero. The bandwidth is 20MHz on the 2.4GHz band, as it should be, and is on the 2.4GHz channel with the lowest interfering signals.

There is the same issue on 5GHz where the Eero is on Ch36 - right on top of the only interfering signal on the band. The interfering signal is about 10dBm down on the Eero. Perhaps it is below the threshold where the Eero will switch channels.

On 2.4GHz the best speed I get is around 40Mbps, even with all my other devices switched off. Is this the best 2.4GHz will do?

Re: Eero WiFi

KeithFrench — Tue, 25 Mar 2025 08:28:38 GMT

Hi @spaarks11

The way that the 5GHz band (whatever router/device combination) is totally different to the 2.4GHz band.

The sort of behaviour you are seeing is perfectly normal. I can explain in more detail if you want, but it may get a bit complex.

Re: Eero WiFi

spaarks11 — Wed, 26 Mar 2025 16:35:33 GMT

Yes, please elaborate. Hopefully I'll understand some of it.

Simplistically I assumed the Eero would scan the band and determine which channels were quietest.

Re: Eero WiFi

KeithFrench — Wed, 26 Mar 2025 16:42:58 GMT

OK, but it'll be tomorrow now.
