Configuring EDUP EP-2906 Mobile Router

The content of this article is from two years ago, I think. I just didn’t have time to finish it for publication then. So the information contained here is probably quite outdated already. Actually it is still not properly finished, but I am publishing it for my own reference.


So after some delibration, I purchased a EP-2906 from EDUP. The primary purpose was to have a way to have a personal wifi access point where only wired Ethernet is available, e.g., when you are staying at a hotel.

The instructions that came with with the product are not the best, to put it mildly. There is only so much you can put on just a small sheet of paper.

Since it does not have an AOSS feature, you cannot use it out of the box as an access point (AP) with WiFi clients such as your smartphones; you have to configure it with a PC first.

To do that, you first have to give your PC a static address of 192.168.1.X. This is necessary because the router’s pre-set IP address is 192.168.1.254, a rather unusual address for this kind of device.

IP address 2 192.168.11.254, following the scheme I came up with earlier. Once I did that, I could revert the settings of the PC for the wired network so that the PC can be automatically allocated an IP address by the DHCP server of the root router (not this mobile router). The mobile router is now on the same subnet, so the PC can access the mobile router at 192.168.11.254.

Set the user name and its password for the web interface

This product has two operating modes which can be toggled by a hardware switch: AP mode and client mode. You would assume that you can have different sets of settings for these two different modes, but most of them are shared, which I find utterly confusing. For example, you can have only one SSID. The wifi password has to be the same for both too. The problem is, in the client mode, you can additionally turn on its repeater mode, which allows other wifi devices to connect to this. If you want to do that, though, the password has to be that of the AP you want to connect to. Since you can have only one wifi password, it will also be the one for the AP mode as well.

So I gave up on the client mode. It is okay, though — I bought this to use it as a portable router primarily anyway. I gave an easy-to-remember wifi password, and turned on the DHCP server just in case. I also specified the

Google Public DNS servers, i.e., 8.8.8.8 and 8.8.4.4, as DNS servers. The subnet mask is 255.255.255.0, and the default gateway is 192.168.11.254.
Other observations: It runs embedded Linux. Its Web server that provides configuration setting interface is GoAhead Webserver.
