Brian Kazmierczak I don’t know where to begin on how to counsel you as to what kind of performance should you expect out of the industry leader Wi-Fi mesh company when you were not using them as Wi-Fi mesh components and just using them as range extenders. It would be more cost effective to buy Xfinity pods and actually benefit from their remedial Wi-Fi mesh capabilities then to absolutely cheat yourself out of the wonders of Wi-Fi mesh with your Eeros because they’re being used as access points which voids them of behaving like a Wi-Fi mesh net work. I’m absolutely crushing with my giganet internet and my new Eero 6 pros Wi-Fi mesh net work as I recently upgraded from the 2nd Gen Eero pros that would absolutely crush your isp speeds if you are 400mb capped atm.

Joffice I’ll make a gentleman’s bet with you where no money shall change hands, but I’m 100% certain you have too many Eero Pro 6 routers and I’ve 100% confirmed after 200 hours of experiments that you are creating too much RF interference which will desimate your WiFi download speeds. My suggestion unplug 4 out of your 6 Eeros, always need the main gateway router, then stand in the vicinity of the additional active router and run ookla Speedtest.net APP on your phone. (Found them to be most reliable overall 24/7). Every Speedtest you run requires a minimum of 2 runs at each new location. I believe it’s mostly determining your max link quality capabilities on the initial test, but implements the higher WiFi link speed to your device for your round 2 test (3 times to be safe iMO). Also, turn WiFi off and back on your phone after unplugging and plugging in a new Eero location because your phone will try to link to your still on main gateway router when enroute to your next test station. And it can take a while sometimes to “shake” that main gateway WiFi connect and it’ll pooch your speed tests for a while and/or really piss you off standing next to an Eero 6 pro BEAST and pulling down pedestrian 2.4G WiFi DL speeds cuz your gateway router still has your phone’s WiFi lock down before the mesh hand off occurs with your proximity Eero. I also theorize that multiple speed tests from static locations allow the Eeros to perform some of their antenna beam forming magic to stabilize and boost test speeds for greater throughput accuracy

Jamesshire I am using them as a mesh network now, and my kids PCs, which are wired with cat6 are still restricted by the gateway to about 40 to 80Mbps. When I use my cable modem as the gateway i achieve the 400Mbps that my plan from the ISP allows. The reason I used them as APs first is because I did not have time that week to switch out my gateway and reconnect all devices, so I used them as APs for a couple weeks until I had some free time to make the switch. I am trying to see why using it as a gateway kills my LAN devices, all wired in cat6 and on a gigabit switch which I know is not the limitation, as it works at full speed anytime Eero Pro 6 IS NOT the gateway.

Brian Kazmierczak is your gateway eero plugged into a switch and your modem also plugged into said switch? If so I recommend a Cat6 direct connect into your modem, sounds like a combo router, with it in bridge mode. Good luck

Jamesshire Hi. Modem to Eero to Switch and modem combo on bridge mode. That’s how I have it. It’s a strange problem. I was a network engineer for a manufacturer before I got into software, so I’m 99% sure it’s setup properly. I used to be a CCNA (back in the day)  I am coming from ubiquiti APs on my network as APs with modem/router as gateway. I wanted to secure+ features for my kids, but it’s killed hardwired LAN performance when accessing the internet. 

Brian Kazmierczak this situation sounds almost identical to when you have something on your network broadcasting as a DHCP server trying to assign Internal IPs. Thoughts?

Brian Kazmierczak oh yeah are ANY of your hardwired Eeros WiFi’ing okay or not all?

Brian Kazmierczak do you have another static IP and diff subnet/domain piggy backing inside your network?

Brian Kazmierczak I’ve seen bloody printers DHCP before LOLZ! Imagine the fountain of expletives that ensued? WHY IS THIS ON BY DEFAULT!!!!!! Hahaha 

Brian Kazmierczak oh yeah, not to insult your intelligence and experience. But many of these modem/router combos have built in Ethernet ports but only one will work properly in bridge mode.

Brian Kazmierczak bro if you wanna voice Comm this I’m available and maybe we can brain storm cuz I’m VERY intrigued by your conundrum and I’d love to help you find a resolution to this Charlie FoxTrot purely out of curiosity and I can add this experience to my “tool bag” jimshire@pacbell.net and I can drop you some digits 😎

Jamesshire Only DHCP server is Eero right now, assigning 192.168.0.x network. I even moved  the  subnet mask to 255.255.255.0 vs 255.255.252.0 that Eero does by default. (i dont need a 252 subnet...)

Jamesshire i moved my hardwire Eero AP to WiFi Mesh to see if that was an issue. Now waiting  for my kids to test  on PC to see.

Jamesshire I used port 1 first, then moved to port 2. its a 4 port switch on the back. crazy part, it seems to be ok with a reboot, then slowly dies out over a day or so. (I have found many people online with the same type of issue)

Jamesshire I may take you up on that, my kids are not home now, so I dont have access to their PCs  and  I have a lot of work to get done today. (I am prepping for a new HPE Alletra full NVMe SAN in our datacenter... VROOM) Might be later this week, as this is not my top priority, more of a WTF is going on here situation.
