I bought a AR-750 and I would like to use it as a switch (cable / WiFi).
I work in motorsport and basically I would like to connect to the ECU (that use an ethernet connection to communicate) through WiFi so that I don’t need to connect to the car to modify calibrations or to download data from it.
If I connect the ethernet cable of the ECU to one of the two ethernet ports (not the WAN port) I can access to the ECU from any computer through the WiFi connection, however if I try to connect to it through the second ethernet port it doesn’t work.
The main issue is that when I download data from the ECU the connection isn’t very stable and sometimes I lose some data, for this reason I would like to maintain both the connection (cable and WiFi).
It seems like the AR750 is working as a switch just between one ethernet port to WiFi.
Can you suggest me something to try to solve my problem?
I am also interested in this issue. MY AR-750 does not allow LAN port to LAN port traffic, ie using the LAN ports as a switch. As the previous poster mentions WiFi to LAN works fine and LAN to WiFi works fine.
I suspect the problem is related to the firewall settings. Any recommendations?
v2.27 does not correct the problem. There is definitely something preventing traffic from passing directly between the two (2) LAN ports.
I even reconfigured the device to be an access point by adding Eth0 (WAN) to the LAN bridge and disabling the firewall and DNSMasq services. With Eth0 added to the LAN, traffic flows to/from either of the LAN ports and Eth0 and WiFi. However, LAN port to LAN port traffic is still prevented by something. Very strange.
Sorry for my bad english.
I solved the problem by editing (through ssh) the “/etc/config/network” file and inserting the following lines at the top:
config ‘switch’ ‘eth1’
option ‘enable’ ‘1’
option ‘enable_vlan’ ‘1’
option ‘reset’ ‘1’
