The attached PDF file can be used to see all of the Help topics located on the Airave 2.5 device. This is what you would see when you are accessing the routers internal menu. If one wishs to access this menu through an RJ-45 Lan port on a PC, then connect to the Airave Lan2 port. Access the Lan adapter configuration on the PC, change the TCP/IPv4 General properties to a static; IP address> 192,168,17,15 Subnet Mask> 255.255.255.0 Default gateway> 192.168.17.1 - then press OK, close all the windows and your Lan port will reset. Open your browser and key in at the command line - http://192.168.17.1/ press enter. A menu will pop-up asking for user name and password, type "admin" (lower-case) in both fields, press OK - or [enter] This will bring you to the Airave menu which is outlined in the attached PDF document.
P.S.: to post above, if you already have a static IP address listed: prior to changing to the settings listed above: make note of all the settings allready listed so that you can change them back to their, after accessing the Airave 2.5.
The DSN1 DSN2 settings are not neeted to access the Airave but make note of them anyway because they will be needed to access the internet if they change. If your oringinal settings are get "Obtain an IP address automatically". then change to that access button and press enter to go back to the original settings.
Only someone with a lot of experience should mess around with the settings.
On the other hand, I use the ethernet out from the Airave to my desktop, and I made some tweeks to make things speedier.
