Hi, first of all, I'm from Barcelona, so my English level is bad, but I need to try!
Well, trying to update my TP-Link TL-WA901ND v4, whit the file: openwrt-18.06.8-ar71xx-tiny-tl-wa901nd-v4-squashfs-sysupgrade.bin via http 192.168... In my case, I changed the default IP to 192.168.2.1 because I use the Tp-Link to range extender, connecting to my main router by wifi.
So, when I pushed the button Flash File, the router has updated but any thing goes wrong, I can't connect with It.
I tried to reset default settings, but don't work. I know this because my edited IP is still 192.168.2.1, not the 192.168.0.1 by default.
When I go to 192.168.2.1 I can see de link LuCI - Lua Configuration Interface but, in a few seconds, the page shows "connection problem"
What can I do to reset or install default firmware?
Sorry for my terrible English! Thanks!
