      I’m trying to set up an ELK-7TS (using the ELK-POE47TS for power and hardwired LAN connection). I did the manual setup for the details of the M1G.

      I couldn’t find a way to set up a static IP address for the 7TS. When I checked the log on my firewall (which is also my DHCP server), I saw that the 7TS was trying to get an IP address from the DHCP server. The DHCP server is set up to assign reserved IP addresses based on device MAC addresses. Unknown MAC addresses are blocked, so the 7TS DHCP request was blocked/denied.

      Another thing I noticed was that every time I rebooted the 7TS, it started up with a different MAC address, and each one was a lot different than the others.

      Is there a way to assign a static IP address on the 7TS (which is my preferred solution)? If not, is there a way to keep the 7TS from changing its MAC address every time it starts? Allowing any unknown MAC address to obtain an IP address via the DHCP server is a huge security risk, so I can’t do that.

      Any other suggestions on how to use the 7TS and POE47TS with a static or reserved IP address?

      Thanks,

      Ira

        Ira – I have not heard of this issue with the MAC changing. Let me talk with Engineering on this. We currently do not have a way to set a static in the screen, I know that engineering is looking into that already. But the MAC issue is a new one for me. I will get back to you as soon as I have an answer.

        Thanks Mike

          Thanks Mike.

          One more thing I found “odd”. I don’t see the 7TS MAC address anywhere on the device, packaging, or on a screen. I thought maybe it came from the POE47TS adapter, but I don’t see it there either. The only way I found it and know it changed at every startup is because my DHCP server logs the MAC address when the DHCP request is denied/blocked.

          I know iPhones have an option to change MAC addresses for privacy/security, but it can be disabled.

          Regards,

            You can view the MAC under the “WiFi” settings. Even though your connection is LAN you can see this in network settings.

            I did some testing this evening and the MAC displayed in the settings is consistent. I will test next week viewing it from the network. I also have a message into engineering, I will report back with their response.

            I also see that Android has an option for randomized MAC, but the option is not exposed in the limited version we’re utilizing for this device. It is possible it is there, but hidden. I will gather more information next week.

            thanks

            Mike.

              I found the MAC address under WiFi -> Wifi Settings -> Advanced. I rebooted the 7TS several times and that MAC address never changed. However, I think that is the MAC address for the wireless interface only and the hardwired ethernet interface uses a different (in my case, different every time) MAC address.

              The reason I think this is because I added an entry to my DHCP server to reserve a specific address for the 7TS MAC address shown under WiFi. When I rebooted the 7TS, it tried to get an IP address from the DHCP server using, yet again, a different IP address.

              Later, I will enable wireless on the 7TS and try to get on my LAN thru my wireless access point using the MAC address I found under WiFi.

              Regards,

                Here’s where things stand…

                I couldn’t get WiFi to work with the POE47TS adapter supplying power to the 7TS. When I tried to connect to my WiFi access point, I kept getting invalid password results. Also noticed that when I select my access point from the list, it almost immediately goes to the pop-up where the password is entered. I was not able to check the “show password” option on the previous screen, so it was more difficult to ensure I was entering the correct password. I tried the password several times, watching closely as I entered each letter, but it kept coming back as a bad password and “try again”.

                I disconnected the POE47TS and connected a 12VDC power adapter. This time, I was able to connect to my LAN after I entered the same password as before. I rebooted and it connected to my LAN via WiFi at startup because I had selected that option. My DHCP server shows it gave the 7TS the IP address that I had reserved for the MAC address listed on the screen mentioned in my previous post. I assume that means that MAC address is only used by the TS7’s WiFi interface.

                I was also able to connect to my M1G. I didn’t try to do much because my M1G is in test mode sitting on my workbench. Based on the few things I did do, it looks like it is working correctly.

                Please do not assume this means I am okay with using WiFi instead of a hardwired connection. I’ve spent a lot of time, effort, and money under the assumption that a hardwired connection will work. As a rule, I use static IP addresses for all my “non-mobile” LAN devices. As previously mentioned, my first preference is the ability to provide a static IP address via a 7TS screen (as I do with all of my hardwired LAN devices). If necessary for the short term, I’m willing to use DHCP as long as the MAC address doesn’t change at reboot, which would require me to edit my DHCP server’s table every time the 7TS was rebooted.

                Regards,

                Ira

                  I apologize for the delayed response. I was finally able to get on a call with Engineering yesterday to discuss this issue.

                  The 7TS is a custom-designed and custom-manufactured tablet that uses a highly customized version of Android. As you noted, Android includes an option to randomize the MAC address for security purposes. Our engineering team disabled this option in the OS, but this only applies to Wi-Fi connectivity. Based on your feedback, we discovered that the POE/LAN adapter is not handling the MAC address randomization disable properly.

                  Engineering has resolved the issue. However, the fix requires these devices to be programmed at the factory. A new batch of POE/LAN adapters is currently being produced, and once completed, they will be shipped in via air. As soon as we receive them, we can replace your device with an updated one.

                  We will update when we get them in.

                    Thanks for the update. Any idea when the new POE/LAN adapter will be available? We won’t be using the 7TS or adapter until our new home is ready in a few months, so it’s not a big problem for me at this point. Just want to know when I should start asking about it if I haven’t heard anything.

                      Hopefully we will have these updated in a few weeks. But due to the shipping time from the factory, it could be a month before we get them in.

                        That’s good news.  I will be running into the same issue when I get everything running in a month.  I just got the POE adapter so what would I need to do to get the “corrected” adapter?

                            We are still waiting for the updated products to arrive. I will update as soon as we get them.
