Well, I used to consider myself tech savvy until I installed OPenWRT on my EdgeRouter Lite 3... sometimes this much flexibility is way too much.. haha
OK, so I flashed OpenWRT to my ERL3, I can access the router connecting my computer to eth0 port at 192.168.1.1 and that's where my success ends.
I have no Internet connectivity. I only get an IP if I'm connected to eth0, I can connect my modem to either eth1 or eth2 but the system status says there is no link. Im completely lost at this point.
With all the documentation available I can't seem to find a general setup guide of things that have to be done after first install to get things up and running.
I'm using the ERL 3 to sit between my ISP's modem and my WiFi router as a firewall but Ubiquiti it seems has about abondoned updates for this device so I wanted to flash something that would keep it relevant and allow me to keep using it. I also use a SmartDNS proxy service, I live in Costa RIca, that allows me to access streaming services from other parts of the world.
So, if i understood you right you do have 3 devices in a line.
ISP-Modem (is it really just a modem or a router in bridge mode?)
The ERL3
Your WiFi-Router.
How are the devices connected? ISP-Modem-LAN -> ERL3-WAN, ERL3-LAN -> WiFi-Router-WAN?
Where are you going to put your credentials (if at all necessary) for your internet connection?
Maybe you could provide a little sketch where we can see how it's all connected, with all IP-adresses.
Yes, this is a Huawei HG8247W5 but it's WiFi is disabled, it is not in bridge mode
Yes, the ERL 3 sits between the ISP modem and my Orbi
Yes, my WiFi mesh network
ISP modem to eth1 (factory EdgeOS uses eth0 as the WAN port but OpenWRT has eth1 and eth2 as WAN ports) - eth0 (normally eht0 on ERL is eth1, but OpenWRT has eth0 as LAN port) port to my Orbi
IP to connect to ISP modem is 192.168.100.1, address given to ERL 3 is 192.168.100.3
IP of ERL 3 is with OpenWRT is 192.168.1.1 and laptop issued IP of 192.168.1.106
I've never had to use any credentials to connect to my ISP's modem
At the moment I do not have it in line, only my laptop connected to eth0 until I get some connectivity
If I try to ping open I just get ping: bad address ópenwrt.org'
The default setting for a device like this (more than one direct CPU port) is that one Ethernet port will be lan (in a bridge named br-lan), one will be a directly attached to wan, and any others are unassigned.
The status page will show the port name assgned to the wan network.
If your ISP requires a protocol other than DHCP (such as pppoe) you will need to configure that in the wan interface. If you use DHCP and the upstream network is also 192.168.1.X (an ISP modem acting as a gateway/router) you will need to change the OpenWrt LAN IP to a different range-- or reconfigure the ISP gateway to passthrough or bridge instead of gateway or route.
Well, I don't know how to make heads or tails of what just happened...
Currently I have a TP-Link ER605 v2 sitting in the place of where the EdgeRouter was, in between my ISP modem and Orbi... just for the heck of it I connected to one of the available ports on that router with a different cable and I suddenly have Internet throught the ERL... hmmmm... I was using a different cable that was already hanging off the TPLINK... I disconnected from the TPLINK and connected to the ISP modem and suddenly had Internet...
Don't know what the deal is but just changing the cable on the connection gave me connection... thing is if I use that cable ANYWHERE else it works just fine and my handheld cable tester says the cable is fine, but if I use it to connect the ERL to the ISP it's dead...
ANYWAY.... now the issue is speed... most I can get out of the ERL 3 is about 125 Mb/s....
So, 2 new issues... fixing that speed and connecting to eth2... I am unable to connect any LAN device to eth2 and get a connection
The CPU in the Edgerouter Lite is not fast. A lot of its performance with the original firmware depended on proprietary hardware acceleration which is not available on OpenWrt.
To make eth2 active as an additional LAN port, go to network interfaces- devices tab and edit br-lan to add eth2 to the list of ports (which will then be eth0 and eth2).
Ok, I think I did this right... once in the Network tab I didn't see anywhere in lan to add eth2 so I snooped around and entered the Devices next to Interfaces, first on the list was br-lan, went in there and hit configure and in the Bridge Ports area I added eth2... is that correct or is there somewhere else to add eth2 to br-lan?
As far as the CPU... it seems far fetched to think the CPU is so weak it can't handle more than a 100 Mb/s connection speed...
