LuCI accessible via Linux and mobile(wifi), not working via Windows

Installing and Using OpenWrt
1

After reading about OpenWRT for quite a while, finally took the jump and installed OpenWRT on my TP-Link Archer C60 v2, everything seems to working including LuCI and SSH access from my Linux machine and from my mobile via Wifi, but then I dual-booted into Windows for gaming. And can't access LuCI or SSH from windows. I'm getting "Unable to connect error". Network is working okay from both systems, so any idea what to check ?

Access it using IP or openwrt.lan?

Via IP, should that make a difference ?

It could, depending on what DNS you browser is using.

Did you change the ip address of your router (relative to the OpenWrt default of 192.168.1.1)

6

I booted into windows and checked, "Unable to connect" error with openwrt.lan also.

No and I can access Luci page at 192.168.1.1 from PC-Linux and mobile, but can't from PC-Windows.

  • maybe post output of „ipconfig /all“ from your Windows
  • is there any other router or AP in your network?

could be your Windows is already using 192.168.1.x for some local virtual network (hyper V, VMware, virtualPC or alike…) or has a seconds NIC config that has some interfering config or some LTE USB dongle is attached to the PC (some USB LTE sticks act like routers).

I would change the subnet in OpenWRT on the LAN interface by setting the static IP e.g. to 192.168.2.1 (or any subnet you like, but that is guaranteed to not yet be in use in your network)

There's only one router and no VMs/USB LTE dongles, adding the ipconfig/all output below.

C:\Windows\system32>ipconfig /all

This is why you are unable to connect. Your Windows machine has a vpn enabled (surfshark via a wireguard connection). Turn that off and you should be able to connect to your openwrt router.

11

I will try after disabling, but I have wireguard to surfshark setup on Linux and mobile too, where I can access LuCI.

12

The WG settings are identical?

And why on earth would you run it on the clients, and not on the router itself?

13

Okay, it seems my wireguard config in windows was blocking untunneled traffic, now LuCI access working.

14

I usually change locations for gaming and streaming, so kept on client. Need to check how to set up multiple interfaces on router.
