Thanks again for you response.
Yeah I have been thinking of resetting the NAS but always forgot because that is the last thing I want to try. The reason is my NAS has this sickness where it won't boot up if is above a certain temperature. I read from another thread about that. So I have to let it sit for a while with air conditioner on. Yes it works that way. I also thought that ALT-F would fix that temp issue but looks like it is not.
Anyway, I already reset the NAS. Will have to wait until it can boot.
To your other suggestions:
1. Already tried direct PC connect not working as well. I usually do that with the old DLINK firmware when managing the files.
2. How do I set static IP from direct PC connect? or will it be automatically assigned?
3. LAN devices has 192.168.1.x IP addresses
4. Yes, DHCP is ON it the routher.
5. I ping 192.168.1.230 up to 192.168.1.254. no luck there.
Again, thank you very much. I hope reset will fix this issue.
