Look at the bold one? I cannot reset, neither restart the router... it is at my other house...

Trouble is no- web page for the menu of router...

I suspect your router and maybe your ISP support IPv6. That is generally what your connection looks like when you can actually use IPv6....though I am not real sure what web sites you would go to.

I would choose a time to reboot when you can take a larger outage. It may fail completely if there is some hardware issue with it. Even if it does reboot you may want to see if there is updated firmware routers should never crash and need to be rebooted.

The gateway is 192.168.1.254, even though you won't have any IPs in the subnet most likely. If it's at your other house, how are you trying to connect your network. You will have to physically reset to get it to go back to 192.168.1.1.

If I remember correctly that is not a issue it is a link local ip and is a common way it works. Best option unless you are actually using ipv6 for something is to disable the ipv6 support in the ethernet setting on your pc. You will be left with only ipv4 stuff. Not sure if that will fix your issue with the router or not. Normally if you key in a ipv4 ip in your browser it will use it even if ipv6 is enabled.

Ok i did that with disabling the ipv6 on the PC, but i still got

"This site can’t be reached
192.168.1.254 took too long to respond.
Did you mean http://192-168-1-254.org/?
ERR_CONNECTION_TIMED_OUT"

when i try to ping it with CMD i get:

It don't make sense. If the gateway is 192.168.1.254, then there is no way that the IP of that computer is 192.168.1.109, the gateway should be 192.168.1.1. Someway, somehow, the settings got all messed up. Can you try to access 192.168.1.1?

The router there - Router1 has DHCP with addresses from 192.168.1.100 - 192.168.1.200 The address of the router is 192.168.1.254

It doesn't allow me to enter with 192.168.1.1 even i try to ping it:

PS C:\WINDOWS\system32> ping 192.168.1.1

Pinging 192.168.1.1 with 32 bytes of data:

That's the thing though, the subnet mask is 255.255.255.0, which means the gateway should be 192.168.1.1, and the router is not properly configured. So a physical reset will need to be done. Is there any port forwarding enabled on this router that you of? Is it open for port 80 ?

I see... I don't think there is any port forwarding on that one... How to check?

Ok simple yeb site...:

Error: I could not see your service on 93.50.134.179 on port (80)
Reason: Connection timed out

SO it is not open... maybe that is blocking me from accessing it

Most likely the reason. Can you access any websites on that machine?

That is the weird now... I am with blocked and closed port 80 - that means no yeb pages at all... But... with slight delay 1-3 sec i can open lots of pages - facebook, i can log into my account, i can use skype, i can log into steam (well after a minute waiting...) But it is working...

Strange things happening

You gateway is fine it can be any address it is just common practice to use the lowest ip. It is less common but still widely done to use the highest IP like your router does. It really doesn't matter you could pick 192.168.1.99 if you wanted to for your default gateway. It just tends to be less confusing to not use strange ones. That is why the default gateway field exists if it could be calculated to the first IP in the block it would not be needed.

I suspect the router just needs to be rebooted. Traffic correctly since you can use teamviewer to pass though it. It also appears to be working correctly for the lan since you can ping the ip of the router. Likely the program that runs the web server has crashed on the router

You should not have to mess with the port forwarding. You never want to forward port 80 and most ISP block that anyway. You already are on the inside of your network anyway because of teamviewer. You would have to get access to the router to change the port forwarding anyway.

I suspect there is not much you can do remotely. Most routers have the ability to be configured via the WAN ip address so you could access the router remotely. This tends to be rather risky because someone else could then attempt to hack their way into your router. Still if you use good passwords it should be fairly safe. There are other security feature to restrict the ip addresses that can access remotely if you want also. But again you have to get access in the first place so your can set these options.

Hmmm The fact that i am connected with the PC inside the network, but i cant log into the router proves your statement that the software program running the router is blocked... Yea... Will see if there is someone around there to jump to my house and reset the device... Or i should stay back for now and try to relax at work (as much as i can) and later when i finish to drive there and see the mist around that Athena thing :D

Well! I would like to thank you for all the thoughts, but one thing didn't cleared for me... How that gateway ipv6 address showed up? Any thoughts?
