I turned off all beta features my WiFi speeds when I am closest to the main EERO is well in line with what I am getting from my ISP. There’s some expected drop off as I connect to the other EERO’s, but nothing unexpected. Much better performance now.

My issue with my Eero was not my actual system it was the hardware connecting it. Make sure you use CAT5E or Cat 6 cables. Cat 5 will not transfer your speeds efficiently.

I totally agree.   I called support and the network engineer I spoke to was able to look at my network and identify cable runs that were not CAT 6.  The better the backbone, the better the WiFi.   

I've got a new EERO gen2 (3modules), 100mps to the house verified by the EERO internal speed test, but only 15-20 at my laptop even at 2 feet. if I connect directly to the ethernet cable I get 90-95. is there any way to speed up the wireless?

Hi,  I am experiencing the same issue.   I purchased 3 eero pro about 2 weeks ago.   I connected 2 of them wired and one of them wireless to my old CAT5  cables and to my new fiber cable modem.   As soon as I configured them,  it was great. I have a 100mbps plan and I was getting wireless speeds of 400 mbps when standing close to each of the 3 eeros,  I was very happy.  Then, I decided to change to CAT 6 cables and connected all 3eeros wired to the network to get more stability and speed.   When we finished the connection with the CAT 6 cables, the wireless speeds are now 20-30mps even standing right next to each eero.   I connected my laptop via ethernet to each of the CAT 6 cables  from each eero as well as the modem and I am getting the 100mbs speeds that I puschased from the ISP.   I have followed the support instructions such as disconnecting each eero and disconnecting the modem... and nothing seems to work.   I spent $500 for 3 eero pros + 200 on cat6 connection services... It is very disappointing  to spend that much money and not get at least 90% of the speeds that i am paying for.

Yeah, I would call them, something is definitely not right.

Same issue. I've got ATT and turned off the WiFi so I'm using just the modem. I pay for 50 mbps and with the ATT router get 40-45mbps. I unplugged and reset my ATT router and primary Eero Pro (1 of 6 pros). Once back online, I got 40-45 mbps with Ookla speedtest.net about 8 ft away and through a wall. 5 min later I did the same Ookla speedtest and got 8-10 mbps. I've turned off all beta features, too. Just checked again and got 3-4 mbps. Any ideas what to do here?

My speed dropped to 5Mbps download and 90Mbps upload yesterday.  This is a wired Cat5 wired Eero.  I thought the eero was bad and removed it but even at the Eero at the Att Fiber modem I was getting the same speeds 5 down and 200 ish up (since that is a Cat6 connection).  I disabled the ad blocking and advanced security in the eero secure menu and the speeds went up to what I am used to.  200 up and down.  I toggled both options back on and the speeds stayed on 200.  So turning the option off and on worked although I fail to understand why it would work so.

I just experienced the same issue..  I have the eero pro and was hitting 900+ mbps with Xfinity(Comcast).  I changed to ATT Fiber and that dropped to 100mbps at best.  Spent about 2 hours with eero going through various steps, even restoring the ATT modem to factory. Called ATT and all was good on their end.  The support rep at eero contacted their engineer and looks like ATT Fiber, or rather their SmartHomeManager app, has a security setting that contains a "ATT Internet Security" that causes the issue with the speed.  Toggled off "Active Security" and viola! 900+mbps consistently on eero.  Not sure if other ISPs have the same, but worth a shot.  Good luck everyone!

The 1st generation, eero and eero Pros' max rated transmit speeds are about 240Mbps at 2.4 GHz and about 600Mbps at 5 GHz. Locally, the maximum throughput over a wired connection is 1Gbps. Maximum wireless speeds are also dependent on the capabilities of the client device.
