Jamesshire No, that is why I mentioned the distance between the APs.

That being said, I may have had a speaker too close to the AP that I am wired to.  I moved the speaker away from the AP and I am now getting almost 400Mbs...😌.

I will keep testing to be sure that was the culprit.

AustinTechie sorry I should have deleted that comment after posting it outside of the thread. Yes you clearly stated that in the thread and sorry for wasting your time as I should have removed my comment. Have a great day

 So that did not last long...later that same day, I reran the speedtest and it was right back to the 40Mbps down speeds. I see no reason for this behavior. 

I am running 6.4 and am considering upgrading to 6.5, but worried about the comments of issues with 6.5. I cannot do without internet due to work.

For the last 4 days, throughput has been consistently 40Mbps. Just wish we has some type of interconnect map with throughput data so we could at least experiment with location and distance.

AustinTechie I haven’t had a single problem with 6.5. Only people that should have any Strange effects would probably be with the DFS where nearby radar signals could cause channel issues. 

AustinTechie have you done a full network restart thru the app or unplug/plug power cycle after the modem has fully been power recycled 

AustinTechie your wired backhaul ? Straight cat 6 cable to each other or via a switch? Moca adapter? 

AustinTechie of you have an android phone or tablet then download the “Holy Grail” of network diagnostic tools called “Analiti” it’s the first app that I’ve found that provides real time signal strength and a multitude of additional capabilities that descended from the gods themselves!!! OMG this app in my hands 5 years ago I’d own a million dollar tech company by now LOLZ!!! There’s throughput diagnostic tools that will actually identify how much RF interference is impacting your downloads: example 300 mb/s DL speed loss due to RF interference etc etc. I doubt there’s another Eero customer that’s spent 100+ hours experimenting with them as I have so if anyone truly benefits from the fruits of my labor please contact Eero and ask them to retain my services as a contractor because my Knowledge base is immense and I’d love to see both parties benefit from a coop. I’m going back to school for a full time MBA 1 year accelerated course and I’ll once again be a struggling student HAHA 

Jamesshire I feel like that is a cop-out.  The major selling point of a mesh network is to not require wired backhaul.  If the wireless interconnect (the mesh) is not going to provide the advertised performance levels, then it is not very useful.

I live out in the country and have very little RF interference. Also, my 60ft spread on my EP6 APs is line of sight...NO walls, just one glass paned door that is almost always open!

While my house has Cat5+ infrastructure, most of these wires are not actually finished out with connectors...I could do a wired back haul, but then I really wouldn't need the mesh.  There are many standard AC or AX wifi solutions that support shared SSID without smart mesh.

I think I was getting better throughput from my Gen1 Eeros (i am an OG purchaser).

AustinTechie I’m OG early adopter immediately when the Gen2 Eero Pro 3+ years ago? It’s not actually a cop out as I’ve had intimate encounters with access points/range extenders where their mere presence halves your throughput and massively increases latency. Now those 2 factors are huge improvements from Eero tech. Not to mention localized packet routing between devices in proximity to each other on the same eero router which means an access point/extender would forward those packets to their main/only gateway router that then reroutes to the intended devices. Whereas Eeros will forgo such unnecessary travel paths and time and send device 1’s packets directly to device 2 when both devices are connected To the same eero thusly cutting out the middle man and all the quality and latency issues associated . A mesh network is not just a daisy chain network who’s sole purpose is to mimic  traditional AP’s or range extenders in a more efficient manner when wirelessly pushing signals out further away from the source router. the ability’s of a mesh network are vast and one of its more exciting attributes  basically emulates your cell phone’s (GSM/CDMA) network where by working autonomously to seek out and provide your phone call with the optimal cell tower for call quality and stability whilst simultaneously traveling 60mph in any given cardinal direction away from your current tower then seamlessly handing your phone call over to a new optimal tower and rinse/repeat for the duration of your call to preserve audio integrity and connection status. As more communications are funneled thru the Internet  (VoIP) I appreciate being able to wander about my property without losing my call connection or enduring disruptive device  handoffs when I’m out of range with the initial access point and my phone has to disconnect and reconnect to the next AP in range. There’s so much more, but to address your comment Eero performs exactly to their advertised capabilities, but those capabilities are dependent on so many customer environmental variables and obstacles outside of Eeros control. I can promise you that without a Cat6 backbone and continued unobstructed line of sight between your Eeros you will not be able to achieve Eero’s advertised performance levels which is by no means their fault. They are culpable for not stressing the importance of my main point which was “ more Eeros isn’t better, as less is more” and not over emphasizing how critical EERO placements are and the huge negative  impacts they will have on each other if placed too closely together. There’s not a mesh system on the market that doesn’t suffer from when a wired backhaul is absent. Wireless backhauls should be used as a last resort with a mesh system as none of them will truly shine wirelessly. That’s why I advocate MOCA adapters as 99% of all domiciles have cable tv coax wires already present in all major rooms and most bedrooms. With the existence of cable tv coax present no one should be running their mesh networks wirelessly. If they choose not to utilize MOCA technology then in my opinion those individuals don’t have the right to complain or slander Eero products becaue they chose not to do what was required to properly utilize their Eero products to their fullest potential (as I do and pull down 800+mb/s WiFi6 DLs, with a 949mb DL throughput hard cap due to 1gb Eero Ethernet Ports, from comfortable distances away from any of my 3 MOCA hardwired Eero 6 Pro routers.) I’m expecting 900+ WiFi 6 DLs after I implement an upgraded innovation I designed that’s thus far boosted my Wi-Fi performance by 50%.  But I can’t discuss it until I secure the intellectual property rights for my invention. Sorry. 

lsellier did you get a new modem from AT&T? Is it a combo modem and router? Model # plz

 Or are you using your own modem?

lsellier if you simply plugged in the new Eeros without completely powering off then on (unplug) the at&t equipment then something like that will happen.  

lsellier is there a software update for the eeros?

lsellier also did you verify that the at&t equipment didn't reset out of bridge mode and you are running a double NAT your Eeros are fighting with the at&t router 

lsellier if you decided for a fresh start with your new Eeros and reset some of the at&t equipment for a new beginning then the at&t router stuff will need to be bridged / IP pass thru etc etc

Jamesshire I figured it out. The eero pro 6 didn’t like an Ethernet cable that the previous generation eero had no problem with. Changed the cable and now everything works well. Thanks for replying to my post. 

lsellier awesome sauce! Inexpensive fix! Gotta love when that happens! Cherish the moment that it was merely a silly cable HAHA

and you are welcome. I’ve experienced just about every scenario with my Eero Pro and Pro 6 and I’ve yet to encounter anything  physically wrong with any Eero device. They really are the best and basically pioneers for residential mesh systems. Eero for Life!!!!

lsellier I mentioned somewhere else in one of these posts about switching all cables to minimum cat 6. Me personally I only switched the cables physically linked to an eero or moca device with cat 7. And all devices like Xbox appletv etc with cat6. Cat5e are HORRIBLE! HAVENT found one yet that delivers remotely close to its 1gig threshold minus the throughput overhead.

Evan (eero support) thanks, I was going to try swapping my Eero Pro 6 in my (hardwired in my second floor) with my Eero Pro 6 gateway as a next step. I have seen a lot of people having a similar issue, so I was just waiting for 6.6, but I will give the swap a try. Thank you and have a nice weekend!

Evan (eero support) side note, I have 400MB with my provider. Sorry for the confusion.
