So If anyone is willing to help me. I have tried everything I found on internet but nothing works.I have moved to another country to work and my laptop won't connect to internet. I live in a house that has 3 floors, rooter is on the highest floor and connection is great there. My phone works normally. I have called a friend and I have brought my laptop to the lowest floor and he just clicked troubleshoot and problem was fixed. It worked for two days then it stopped again. So I took my laptop downstairs again and It was working but the connection was so bad there so I don't understand if my phone can't even connect how can my laptop only work there. The owner of the house has her laptop connected via lan cable and hers is also on the 1st floor that has bad connection and my laptop works only when its close to hers. I don't know what is going on here but I need my laptop. I cant connect it to lan either because it doesn't recognize the cable. Nothing seem to work for me can you help me please. My laptop is dell latitude D810. It worked just fine back at my house I just think that I'll never fix this.
