    Question Help a noob TL-SG105E, basic setup

    Model :

    Hardware Version :

    Firmware Version :

    ISP : [/COLOR]

    Just bought the switch TL-SG105E but didnít realize that it was a managed switch. It says it's "smart" and should work out of the box so I would assume that it might be ok. I bought it to replace my switch behind the TV (with loads of stuff into).


    I have connected the switch to my router on switch port 1, Iíve successfully logged into the switch admin (after manually setting IP etc on my Computer) from port 2 to computer and enabled the DHCP.
    It didn't seem to help and I'm kind of the end of the line with my knowledge at this point.



    The router doesnít recognize the switch, I cannot access the switch despite setting custom IP for switch MAC in the router. All devices connected to the switch get "false" ip (169.168 etc) not 10.0.1.34 or 192.168.0.2 etc (I use the 10.0 xxxx series in the router).


    Can someone help me out here, is this not the way a managed switch work?

    The router needs to provide DHCP for all other devices if you don't use static IPs in your network. The switch cannot provide DHCP, at least not the TL-SG105E.

    If your network's IP range is different from 192.168.0.0, the switch can be used instantly without configuration, it's plug and play in this case.

    If your network's IP range indeed is 192.168.0.0 or you want to access the web UI of your switch from any other device, follow those steps below:


    Step 1: Find out the IP range used by your router on its LAN (for example, 10.0.1.x or 10.0.y.x). Make note of the netmask also (e.g. 255.255.255.0 or 255.255.0.0).

    Step 2: Find a free IP in this range not used by any other device, router or DHCP. For example, if the switch uses 10.0.1.1 itself, you might use 10.0.1.2 for the switch if this IP is still unused by any other device.

    Step 3: Set the switch to factory settings first (press the reset button for 5 sec. or more).

    Step 4: Connect the switch to your PC directly (do not connect the switch to the router!). Assign your PC a static IP in the 192.168.0.0 network (for example: 192.168.0.2).

    Step 5: Got to the switch's web UI at http://192.168.0.1/ and log in. Now assign the switch a static IP determined in step 2 (for example: 10.0.1.2). Assign the correct netmask you noted in step 1. Apply those settings, but do not power off the switch during two next steps 6 and 7. After applying you won't be able to connect to the switch's web UI again until steps 6 and 7 have been done.

    Step 6: Change your PC's IP back to the 10.0.1.0 network. For example, set it to static IP 10.0.1.3.

    Step 7: Go to the web UI again, it now can be reached at http://10.0.1.2/. Login and save the configuration of the switch ("Save Config" menu). Now the switch is part of your 10.0.1.0 network and you can always use this IP to connect to its web UI.

    Step 8: Finally connect the switch to one of your router's LAN ports. For a quick test, ping your switch at 10.0.1.2 and your router at 10.0.1.1. Change your PC back to DHCP if you want to do so, but you could also still leave it at the static IP set in step 6.

    That's all. Now the switch is part of your router's network.

    Also consider upgrading to the latest firmware. This fixes a known bug with "Save Config" not always working in older firmware versions of TL-SG105E/108E.

    Thank you for this effort =). I read in the manuals and in the forum and ended up setting the static ip as of my router range. That didn't work at first and it was so strange. Then i changed the internet port from 1 to 3 and suddenly everything started to work. Tried the port 1 again later but same error result. Guess the port 1 cannot take line in?

    All ports should work the same way. If port 1 has a defect, you should RMA the switch.
