Ethernet connections dropping Eero gateway

Message 1 of 13
(2,322 Views)

I have a G1100 and it has had 2 Ethernet connections for the last 2 years. One of those connections was my Eero pro router.

 

A few weeks ago I added a third Ethernet connection to the gateway - a laptop for work. Last week my Eero network dropped off as disconnected. In the Fios gateway page I tried romping g it and it kept failing. I tried and tried to reconnect the Eero and thought that the LAN adapter must have been busted. Finally I disconnected all devices and restarted the gateway. I added the eero first to port 4 and it worked fine! So I added the laptops on 1 and 2 and the eero went back to disconnected!  I disconnected the laptops and it came back up. What exactly is going on and how do I fix it?

Can you run speed test on your two computers? For speeds lower than 100Mbps, it is commonly indicative of a bad cable or bad Ethernet port. Can you swap the EERO onto a different LAN port on G1100 and try again? Thanks.

Have you configured your EERO to "bridge mode?" You need to disable EERO's DHCP server. You are likely experiencing an IP conflict.

If I set the eero to bridge mode, that would allow the Fios gateway to assign IP addresses as necessary correct? Is there a potential for problems there? I have a lot of devices connected to the eero network like smart light switches, echos, alarm, etc etc.

Do you currently have a double NAT setup? Meaning your Verizon router establishes a LAN network and your EERO establishes another network within Verizon router's LAN?

Yes, DHCP is set to auto on both.

DHCP is a protocol for handing out IP addresses and it has nothing to do with Network Address Translation. Could you draw a diagram of your network for us to better assist you? Thanks.

Ont and gatewayOnt and gateway

in this layout I have Ethernet ports 1 and 2 hard wired to 2 laptop workstations. Port 4 is where the Eero gateway plugs in. After resetting all of the connections and replacing them, I put the Eero in Bridge mode.  My bandwidth is seriously diminished however.  2 weeks ago I would run the built in speed test in the Eero and get 950Mbps up/down and now that number has collapsed to 95Mbps. I swapped the Eero for a spare and nothing changes. What the heck is going on?

I swapped ports to number one and the speed test remained at 95Mbps, after the speed test the gateway dropped the eero again. Even though I swapped to a new eero base station and set it up as a bridge. I swapped the cable out and did another test and the same speeds came up. If I’m having some sort of IP conflict is there a way that I can hard code an IP address for the eero while keeping all other devices in auto dhcp?

New setupNew setup

So I spent a few bucks and changed a few things on my network and yet I’m still getting poor speed tests. Here’s the new setup:

 

1. NAT to fios gateway via blue cat 6

2. Fios gateway LAN 1 to Eero via Cat 6

     - Gateway DHCP IP assignments begin at 192.168.1.2

     - WiFi is off

3. Eero to 5 port gigabit switch via cat 6

     - Eero DHCP assigns IP addresses starting at 172.168.0.1

     - additional settings

4 gigabit switch provides Ethernet connection to 2 laptops and NAS backup

 

I have tried speed tests with the Eero in all Fios gateway LAN ports and can’t do better than 95 Mbps. The fios speed test I just tried tonight had 5, yes 5 Mbps.  Could Fios be throttling me for some reason because of all the resets I’ve been doing?
