I have a AX1800 wireless router. When I first opened it, it worked fine for about 30 minutes. I got my computer connected to it and could access the admin portal. After I tried to set up nord vpn (which I subscribe to) without warning, I lost connection to the admin portal and I can no longer access it. I tried holding the reset button for both the 'repair' and 'reset' times. No improvement. I tried to unbrick via uboot, but I cannot open up the 192.168.1.1 ip address.
To sum up the symptoms that I am seeing:
1 - no wireless ssid's are being broadcast. Not the new name I gave it on initial setup. Not the default name after trying to reset.
2 - when I try to open in any web browser the admin portal (192.168.8.1) or the uboot firmware portal (192,168.1.1) when following those instructions, I get "access blocked"
3 - when I set try to ping the ip addresses (obviously when I have set my ip address on the computer in that range as the instructions state), I get a "general failure." I got this initially when the trouble first started.
4 - the device does power on. when I hold the reset button per the uboot instructions I do see the flashing blue then solid white LED
What is going on? Seems like the thing is completely bricked and any route to unbrick that requires me going to some kind of web portal via an ip address does not work.
Are you sure there is not a local ip conflict going on between the ip of the router before the flint and the flint?
Try this under windows:
Set the dhcp back to normal, look into the sys tray if its identifying the network, if not use win+r type cmd, then in this prompt type ipconfig /release and then ipconfig /renew this must force a new dhcp request from the Flint.
Since the led colors white, it sound to me like the flint is working fine but there might be a ip address issue.
I can also advise in some cases to just do a restart loop from isp modem, to a possible switch and then the flint and any other network device after, maybe some other network equipment could cause the problems, i often see these kind of things happen on a switch.
As example ive seen cases that my tp-link switches started sending vlans from ingress (input) to egress (output) with the same mac address as my own router... thus causing it to block instantly by openwrt, but i also have seen switches losing their ip but all other functionality kept working a restart fixes most of these issues, i never seen a switch block internet from the router directly, but again it solely depends on how good the implementation is.
It seems that you have vpn turned on on your computer. Pls turn that off if you want to access the router web UI. Vpn on PC will prevent you accessing local LAN.
