TL-MR3020. After installing OpenWrt no access to the interface

Hello and greetings to everyone.

I have a router TL-MR3020 (EU) ver: 3.20. I uploaded tplink_tl-mr3020-v3-squashfs-tftp-recovery.bin (from using the Tftpd32 program on a Windows 7 computer. It looks like that the installation was successful because the system sees the router and pings it but there is a problem because I can not run any console. LuCI web interface not work and when I try to access via SSH when connecting in SmartTTY it shows the error "Cannot acces .shh directory". I was able to connect via WinSCP

I have access to files but not in what to do next. I tried to look for a solution but I didn't find any clue. I am asking for any advice on how to diagnose the problem.

Snapshot builds do not include Luci code. You should be able to ssh in. Well-proven Windows ssh clients include Putty and Tera Term.


@Marcin, welcome to the community!

I think you mean .ssh directory? It is error of the client program, not the router. It could be the program does not have necessary permissions to create the configuration directory where it wants, probably. Perhaps you can debug the program and see what exact path it tries to access, then give the necessary permissions.

The message above has some suggestions for Windows based SSH clients, they will probably let you access the router and run a command or two without problems.

However all the Windows programs I did check out did not provide satisfactory results as terminal emulators for me, so I use xterm + OpenSSH personally. Windows programs kinda work, but that's all.

Yes with a late version of Windows 10 you can use Microsoft's CLI ssh, which is a port of OpenSSH.

The main problem with SSH on windows though is lack of satisfactory terminal emulator. So I don't think it's going to help. Out of all terminal emulators I tried, I like Konsole the most, but windows doesn't support it, so I don't use windows

Your advice is correct. I was able to connect PuTTY with the router and enable wifi. Thank you.

I have another problem. I want to install the LuCI console but I can't connect to the internet on the router and I want to install offline console but I can't find LuCl packages for this version of MediaTek MT7628NN. Can I apply packages from another version?

Assuming you can physically connect to the internet via ethernet, your best bet would be to change the network and wireless settings to give you a wireless LAN + wired WAN.

Also, the MR3020 is going to be short on space -- if you're just looking for LuCI, it will probably fit for 18.06.5. But you won't be able to install any other packages unless you run extroot.

v3 has 8MB flash.

I'm having trouble setting up my internet connection properly. I'm trying to install offline. What do you mean to run extroot?

I didn't realize that! I have the v1 and v1.9 and then an TL-WR902AC.

Forget what I said about extroot -- @tmomas's comment above points out that there is enough flash memory for some additional packages.

Regarding your issue getting it to work with your internet connection -- can you elaborate? Are you comfortable issuing UCI commands (on the MR3020 OpenWrt command line) and/or editing the config files manually (using vi, for example, or copying it to your computer to make changes and then moving it back)?

I can't handle the router configuration. I have access to files on the router through winSCP and can edit them. Via puTTY I have communications via SHH.

Here is a script I have used to setup the network so that the WAN is on ethernet and Wifi is enabled for the LAN. Feel free to edit as you'd like, but fundamentally, you can copy this into a text file and save it, then transfer it to the MR3020 and execute it.

# This script will continue setup of the TL-MR3020 basic networking
# LAN will be configured on Wifi as specified in this file along with the network address space. DHCP server is enabled for LAN.s
# WAN will connect via wired ethernet and request IP address using DHCP

# Wirless network config

# LAN configuration

# System configuration

# Setting the 'system' configuration for hostname and timezone.
uci set system.@system[0].hostname=$hstname
uci set system.@system[0].timezone='PST8PDT,M3.2.0,M11.1.0'
uci set system.@system[0].zonename='America/Los Angeles'

# Wifi radio is disabled by default and is enabled by deleting the 'disabled' line
uci delete wireless.radio0.disabled
uci set wireless.@wifi-iface[0].ssid=$ssid
uci set wireless.@wifi-iface[0].encryption=psk2
uci set wireless.@wifi-iface[0].key=$key

# LAN was originally bridged (type) and was using eth0 (ifname), WAN was not configured.
# Delete ifname and type for LAN to unbridge and free eth0 for use with as WAN.
# Setup WAN on eth0 with DHCP address request protocol.
uci delete network.lan.ifname
uci delete network.lan.type
uci set network.lan.ipaddr=$lanip
uci set network.wan=interface
uci set network.wan.proto=dhcp
uci set network.wan.ifname=eth0

# Commit changes

uci commit wireless

# Restart system and network stacks
echo Network updated - LAN @ wifi SSID $ssid with WPA2 encryption + password $key and WAN via ethernet
echo Connect ethernet to WAN.
echo Restarting network...

I have internet from a cable TV router but I can't configure it. What is the best way to connect the TL-MR3020 to get an Internet connection and download LuCl?

Take a look at the script I posted previously. It configures the LAN on Wifi using an uncommon network range so that it will be very unlikely to conflict with the network configuration that you'd find on most standard routers. The MR3020 ethernet port then becomes the WAN port.

If you are able to successfully run the script, you can then simply plug the MR3020 into your existing network and it should work. You'll then connect your computer or phone to the MR3020's wifi (which if you just run my script directly will be "MR3020" with a WPA2 passphrase "TL-MR3020"

(You probably have ethernet ports on the back of your existing router -- you can use one of the LAN connections to connect an ethernet cable between that and the MR3020.)

OK, I'm in a dimly-oriented programming. Can you tell me where to upload the script and how to run it?
Should I save it as a * .sh file?

Copy the code into a text file. Save it as a .sh file (maybe

Copy it to the router via Winscp.

On the router, navigate to where you saved the file and add execute permissions

chmod +x

Then execute it


thank you for your help but I have no way to check your file because the router has broken, the software has leaked and I can't even put it into flash mode :frowning:
