There are no "user" accounts on dd-wrt. Only root. When you configure a username/password on first boot, the username is really just an alias for root. IOW, you're actually configuring the root account. When you subsequently access telnet or ssh, they require root as a username. It's the GUI that uses the alias.

I know, confusing, but that's just the way dd-wrt has always worked.


ok i will log out of ssd and test with telnet
but why did the web gui now doesnt accept neither root or the user i created? any way to fix that?

and yes i can telnet using root/mypassword but that does not work on the web gui

Code:
nvram get http_username
nvram get http_passwd


Encrypted, of course.


true got a ton of letters on each of those
any way to delete those or decrypt them
also they can be right but the server discard them
makes no sense that after turning ssh or telnet on those wont work anymore

Encryption is a one-way function. You can't decrypt them back to their original input value. That's why they're used. When someone logs in, the service takes the passed username/password, encrypts them, then compares the results to what's stored in nvram. IOW< even the router doesn't know your username/password when it comes to the admin page. Only the encrypted results.

Not sure why you'd want to delete them anyway. I've seen ppl delete and replace them w/ encrypted values based on known input values, typically because they've forgotten the original input values. But not just arbitrarily deleting them.


what are you talking about i dont want to do anthing like this i know what encription does that is not the point here i just want to have access again to the web gui or have some command to reset it as there is something on the firmware that stop working when i turn telnet or ssh on

You're messing w/ mods, so who knows what effects those mods might have had. I also have no idea what you do and don't know. Or the true situation there. I have only what tidbits you provide me work with. I have to assume the worst and make my best guess as to how to help you. And at the moment, that's the best I have.


no not really i m using a plain version of the firmware downloaded from the site i didnt add anything to it yet the only thing i did is replace the 5g card and it is working

this problem is brand new something is odd here

The minute you change the hardware, no matter how trivial you may assume that change to be, all bets are off! You can't and shouldn't assume anything. You're in uncharted territory. And that's why it's hard to provide help, esp. across this forum.


that is true but the new card is working perfectly i just upgraded the firmware to DD-WRT v3.0-r39827 std (05/20/19)

its also beta so some bugs will eventually show up
the 5g card is working all this firmwares were made by BrainSlayer its the http /telnet/ssh that is odd

i will test now with this firmware and check if i still have the same problem

Connection to router disruption is to be expected. Did you wait at least 5 minutes and open a new browser tab/window and open http://192.168.1.1 (or whatever you set router IP to) and see if the firmware version upgraded? You may be running a release that webUI upgrade is broken in.

If webUI upgrade is in fact not working, you have a couple of options. Via telnet / ssh, you can do one of the following:

For US market models:

Code:
cd /tmp
wget -O firmware.bin http://ftp.dd-wrt.com/dd-wrtv2/downloads/betas/2023/06-02-2023-r52869/tplink_archer-c7-v1/tplink_archer-c7-US.bin && tail -f /var/log/messages


For other market models:

Code:
cd /tmp
wget -O firmware.bin http://ftp.dd-wrt.com/dd-wrtv2/downloads/betas/2023/06-02-2023-r52869/tplink_archer-c7-v1/tplink_archer-c7.bin && tail -f /var/log/messages


These will show flash progress or tell you if the firmware image size is too big. That is for the current DD-WRT release as of this post.
