I'm trying to get my home wifi working. It has never worked. My computer can't connect to it using Ubuntu or Fedora. My mobile phone can't connect to it.If I enter 192.168.1.1 I get a timeout. So I can't look inside the router to see if there is something I can set to make it work.

I don't know why I can't connect to 192.168.1.1 That is the address printed on the back of the router, along with 'useradmin' as username and the password.

How can I force the browser to only look at the local network?

the Output of ifconfig command shows that your computer did not have any IP address allocated in 192.168.1.0 subnet. Are you sure your computer is connected the router? To check DHCP or all other setting on router, try by giving the static IP to your computer in subnet of 192.168.1.0 e.g. 192.168.1.34/24. Then try to ping/open 192.168.1.1

The dsl cable is working, I can access the internet through the router to write this. My mobile phone also sees the wifi. It is Android, but it only says 'obtaining ip address' and never gets any further.

So I'm thinking, I need to switch something in the router. But as you say, there is no 192.168.1.1 address in the ifconfig. Why not??

I dont know how your computer is able to access internet. But to access router as i mentioned earlier assign IP 192.168.1.45 to the computer manually using command
Then try to ping and access 192.168.1.1 in browser

Hope it may help

Thanks again. I am a bit wary of messing with the ifconfig. If I do that, will I be able to reset it to normal easily? I don't want to lose the internet connection completely! Bad enough that the wifi never works, hasn't worked for 2 or more years. But in the office it works fine, same thing, a router with wifi and dsl sockets! There the wifi works no prob, so I rule out a hardware fault.

Well, I did a reset of the router. Now it is showing 192.168.1.1 But I still can't connect to the wifi, not with the computer, not with the Android phone! The phone says it is connected to the wifi, but it has no internet access. I can get that over by enabling data, but that is the same as making a phone call, so it costs me money. The wifi is in my yearly subscription, and should have no extra costs.

Here a screenshot. Says I am connected to the internet via wifi, or at least to the router. BUT, if I unplug the dsl cable, I have no internet access.

Does anyone know why?
