Default Cannot logon to RT-N66U.

Been having this issue with the RT-N66U. Even though I've pressed the "Logout" button after changing settings, the next time I try to access the RT-N66U (192.168.1.1), I get a message that says:

Quote:
Login user IP: 192.168.1.100
You cannot Login unless logout another user first.

Anyone know how to fix this?

Connect through telnet, and run the following commands:

Quote:
nvram unset login_ip_str
nvram unset login_timestamp
nvram unset login_ip
nvram commit
If you can't telnet in, you will have to power cycle your router.

I should probably Google how to "connect through telnet", but what exactly do those commands do?

Eh, just power cycle your router then, it will be simpler If you don't know what telnet is, then you probably didn't enable telnet on your router, so you won't be able to use it.

Those commands would have erased the nvram settings that tells the router that someone is already logged in, and from which IP. The RT-N66U cannot allow more than one simultaneous user to be logged in, and if your IP changes before you log out, you will be locked out.

Thanks again. So those commands are not a permanent fix for this issue. I hope this is "fixed" in a future firmware update.

Is there a tutorial in setting up and using telnet with the 66U? Are these commands something that can be done using a batch file?

Go grab a copy of Putty for telnet and/or SSH.

... I once saw this tip somewhere... you can also enter the following at the URL instead of telnet:
http://192.168.1.1/Main_AdmStatus_Content.asp

Once at this page, type:
mtd-erase -d nvram
Push Enter key and wait for confirmation in the lower portion that nvram was erased.
Now type:
reboot
Push enter

I also noticed that a hard factory reset also does the trick sometimes.

Your suggestion will erase ALL settings. A bit overkill just for a login issue, don't you think?

LOL, true... ... thing is when I get problems I save .cfg file, factory reset and clear nvram.... suppose it doesn't help if you save problem into the .cfg file. Whilst on the topic, isn't it possible to type your code into that URL-based page as well: "http://192.168.1.1/Main_AdmStatus_Content.asp"?
