Have I bricked my system?

I've been trying to get smartphone USB tethering installed on my TP-LINK TL-WDR3600 using this guide:

In the process of upgrading the system, I fear I may bricked it. It gets an IP addressed via my DHCP server and I can PING it but ssh and web access is refused.

Is there anything I can do to recover it?

or try reinstalling openwrt https://openwrt.org/toh/tp-link/tl-wdr3600_v1


I don't see any upgrade process in the guide. In which step did you get stuck?
If it gets an IP address from the dhcp, it means that the port you connected is wan and it is expected to deny permission to ssh and http. Connect your pc on a lan port, get automatic settings with dhcp and browse to to access the Luci.

I reflashed the device and had it working with a static IP of 192,168.1.1 acting as a DHCP server. I was able to connect from a PC run ssh and changed /etc/config/network so that the device acquired the IP address from my pfSense. Maybe I made some typo but subsequently was unable to ssh or browse the device.

Subsequent attempt at recovery have failed, but that is probably due to my misunderstanding of the instructions

You could try to connect over IPv6 then. Hopefully that part of the configuration was not affected.


ipv6 link local addresses are a total savior!

ping -6 ff02::1

Should give you a reply from every machine on the network. If you just connect to the router by wire and disconnect everything else, then the only reply will be the router.


I've just tried the factory reset option again, and this time I managed to follow it properly and have regained access.

Unfortunately I can't configure the system how it was before the upgrade.
I want the device to use my DHCP server to get its IP address, but I would also like to configure it as a router, basically an access point for any other system on the LAN.

I'm having problems configuring my /etc/config/network to do this.

Any advice on getting this working would be much appreciated.

If you don't need the routing, just wireless - https://openwrt.org/docs/guide-user/network/wifi/dumbap
Set the LAN interface to dhcp client.

If you want it as a router, use the WAN port, it's set up as dhcp client by default.
