IP configuration TP-Link MR3020

[hamburger07]

Hello,

after flashing TP-Link MR3020 by using mr3020-v1-15.05.1-factory and mr3020-v1-15.05.1-sysupgrade I was able to connect to the device from PC (runnig with OS Windows 10) via LAN and IP 192.168.1.1

I enabled WiFi OpenWrt and found the device on my android tablet with SSID OpenWrt, but connecting to this device was not possible - the tablet was searching for IP adress but could not find.

After checking my other devices I found my Internet-router (O2-Box) using the same IP adress 192.168.1.1

Therefore I changed my flashed TP-Link MR3020 to dynamic IP via DHCP (range 192.168.1.2 to 192.168.1.25) - and now I don't have any access.

It's still shown in the list of network devices on my PC as OpenWrt but checking the properties it shows 'faulty IP configuration'

I tried to reset to MR3020 to factory settings by pressing WPS/reset button for more than 10 seconds - no result.

Any idea to solve this issue?

Thanks for any support

Check this: https://wiki.openwrt.org/toh/tp-link/tl-mr3020
The 'Failsafe Mode' if you manage to enter the failsafe mode you can connect it to your PC and then follow this: https://wiki.openwrt.org/doc/howto/gene ... ilsafemode
The "Wiping JFFS2 file system ('Factory reset' to default config)" part
You will need Putty or other console application to establish a telnet connection with the router at 192.168.1.1 IP
then you would need:

Code: Select all

mount_root
firstboot
rm -r /overlay/*  (or /overlay/upper/* on some routers)
mtd -r erase rootfs_data (this will reboot the device as part of the process)

Hi,

very nice: using yours below I was able to get access to TP-Link MR3020 and LuCI interface via LAN and IP 192.168.1.1 again.

But the main problem is still existing: My internet router (O2-box) is also using IP 192.168.1.1 and i can not connect to TP-Link MR3020 via WLAN - trying to connect on my android tablet it shows 'requesting IP' for long time without any result.

By the way: should I establish DDServerApp or OpenWRT?

Thanks for your support!

After you connect your Android tablet wireless to the MR3020 wireless, your Android tablet will be disconnected from your home wireless router so it is not a problem that both use the 192.168.1.1 IP.
By default the wireless AP has the 'DDServerAP' name.
You can check this in the OpenWrt web interface under 'Network->wifi'
You can change the IP address of the MR3020 by going into 'Network->Interfaces' and then pressing the 'edit' button for the LAN interface.
Under 'IPv4 address' change the IP, you can try 192.168.2.1
Also change the 'IPv4 gateway' and the 'IPv4 broadcast' to match it.

Hi Zoltan,

meanwhile I'm able to connect my android tablet to WLAN 'OpenWrt' via IP 192.168.1.1.

In OpenWrt Menue 'Administration - SSH Access' I set the port to 4757 (default was 22) - is there any other way to configure the device port?

After starting qDslrDashboard and pressing the WiFi button it shows

'Enter DDServer IP adress
IP adress 192.168.1.1 Port 4757'
When pressing 'ok' 'connection info' is showing:

'Searching for DDServer
DDServer not found, connecting to IP: 192.168.1.1
List connected DSLR at IP: 192.168.1.1'

That's it. Attached to MR3020 is my NIKON D810 (via USB) but there is no connection.

I tried to attach some pdf-files with MR3020 settings but looks like pdf is not accepted...

Sorry for bothering you again but your great support is highly appreciated!

Please don't mix SSH with DDServer.
SSH works on port 22 and DDServer uses port 4757.
So after you change the SSH port to 4757 probably DDServer will not work at all.

ok, I set back SSH port to 22 - but no success: DDServer still not found by DslrDashboard even the processes showing ddserver running.

Anything else I can try?

Did you check this post: viewtopic.php?f=5&t=2101

ok, I checked and tried out. It's strange: I can connect to WLAN OpenWrt and it's showing IP 192.168.1.1 but I can not connect to the device via http://192.168.1.1 (website not available). I tried on my windows PC and on my Android tablet - same result.

Connecting my PC via LAN to MR3020 is no problem

Please try and reflash with the sysupgrade image following the instructions here: https://dslrdashboard.info/tp-link-mr30 ... e-upgrade/
Please uncheck the 'Keep settings' option.

After you flashed open the OpenWrt web interface at http://192.168.1.1 and navigate to Network->Wifi and do some screenshots.
