@alzhao Why should that mean something? But okay I just tried Ubuntu and the same issue happens.
I am not sure what is the problem you met.
The problem is what I say in first comment:
Upgrade firmwares to 3.1 (testing) for mt-300a.
Go to 192.168.8.1
Automatic redirect to 192.168.8.1/cgi-bin/luci/webpanel/homepage
404 error because not exist this page
Access OK to Luci at 192.168.8.1/cgi-bin/luci
To make sure, I got a new AR750 router, flashed the same firmware 3.100 and I have no problem.
This is mt300a. (But also another Thread for AR740)
Which old firmware did you upgrade from?
I try all of them but the most recent is v1 for mt300a.
Can you clear all settings and try again?
I already do this before but also do it again now. I clear settings, I do uboot, I flash firmwares to 192.168.1.1.
@alzhao do you see my question above? It is best for troubleshooting I think. I ask:
Maybe you can tell me what files I should find on router when I SSH and look into /www ? I will look manually for these files.
