Problem after "factory reset" (no access via Web/SSH) Asus RT-AC58U

Installing and Using OpenWrt
1

Hi everyone,

At the beggining I'd like to sorry for my english.

Recently I installed OpenWRT (18.6.1) on my router (Asus RT-AC58U) using stock2openwrt.trx from 4pda.ru.
Everything works fine, but due to my mistake I lost connection with router (disabled DHCPs). So I followed "soft factory reset" method described OpenWRT's Wiki.

Unfortunately, after 1st command (/overlay) I've received alert (I don't rememebr meaning...). After the whole procedure the router restarted, assigned addresses to PCs, but there is no possibility to connect with router via Web (192.168.1.1) or over SSH ("connection refused"). I found, that the similar situation was described here.

But I'm totally newbie in OpenWRT and in general in Linux-world - I don't know, what should I do now to not cause major problems and restore access to the router (re-flash device?)... Could you please help me?

Can you ping the router?
Can you connect with telnet instead of ssh?

  1. PING -> yes, it works (time=1ms, 0% loss).
  2. Telnet -> "connection refused" (same situation SSH)
4

I would go with reflashing just to be sure that everything is as it should be.

Use the sysupgrade image

Ok., but how can I do it, if I don't have access via telnet/SSH/Web?

First try to Reset the router, by pressing the reset button for about 10 seconds while the router is on. The leds should start blinking and the router will reboot. Check if after that you can access web/ssh/telnet.

Otherwise try the option to push the image by tftp while the router is booting.

10 sec. reset -> Wow, after that SSH/Web access works! Thank you! :slight_smile:

Please tell me, what should I do to completely "ovewrite" existing software/data which might be interupted during "factory reset"?

:sunglasses: glad to hear it.
What you just did should have already wipped the overlay of any data.

Also, can you please mark @trendy ‘s post as solution if its fixed the problem for you. (It’ll help others with similar problem find the answer too)

Ok., so I have last 2 questions :slight_smile:

  1. Installing once again OpenWRT (sysupgrade) via Web (without saving settings) -> is it ok., solves any potential problems or may produce some problems?
  2. I've checked syslog and found few "problems" - is it ok.?

Without knowing the details about this router, some generic comments:

These point to some error in hardware definition of the device. Likely DTS has somehow wrong USB definitions. Possibly your USB ports (at leaast port 4-1) does not work optimally.

These errors look "normal" ath10 firmware load errors from trying various methods before succeeding with one method.

It can solve potential config problems (if your config attempts have caused invalid values). Installing again OpenWrt sysupgrade without saving settings basically causes all OpenWrt settings to start again from OpenWrt defaults. If the defaults are ok, you are good. (But if the device's defaults are wrong, then you may have similar problems as with the earlier time(?) )

You can also cause the same effect by resetting the router via LuCI or via "firstboot" command.

You could run the command firstboot to make sure that everything is back to the original state, right after the firmware upgrade. There is also a factory reset option in the webgui.
