I tried numerous times always without luck. I am trying to use the WRT 1900ACS as an access point and i have openwrt installed on it.
I use - EPC3928S EuroDocsis 3.0 2-PORT Voice Gateway - which is a default device provided by my internet provider (Telemach, Slovenia), from there the cable goes into the 2nd floor where i have a 4 port switch. From there the cable goes into the AP wannabe.
I have set the starting IP address at 192.168.0.10 to make sure that I would be able to assign 192.168.0.2 to the AP, but it always looses contact and wants me to revert. (I have the device plugged directly in my PC during config). I gave up an left it with the default IP (192.168.1.1) and followed the guide on how to set up access point using the LUCI interface (Disable DHCP an all that) and turned on wifi.
After "successfully" setting it up, I plug the AP into my switch and the wifi is there but the internet is not and I cannot access the newly created AP using the default IP (192.168.1.1). Both devices (my PC and AP) are connected to the same switch and are on the same local network. The AP is connected via LAN port.
My head will explode, if someone with more knowledge can help me out i'll be eternally grateful.
