I don't have any internet in my room and I just got a brand new desktop and a pci-E wifi adapter, supposedly so I could connect the desktop to my wifi-extender and have wifi. But there's this problem, the desktop simply refuses to connect to the hotspot. IT DOES CONNECT, but it displays this error I got 0 internet access. And the most frustrating part is that the wifi works perfectly on my phone, I'm using it as we speak and to post this also. I tried dns flush, releasing and renewing IPs, resetting the wifi extender over and over, NOTHING WORKS and it's driving me crazy!! Wifi is working on phones but not on computers, it doesn't even work in my laptop either!!

PS: Chrome says DNS_PROBE_FINISHED_NO_INTERNET and Windows Network Troubleshoot says wifi has an invalid IP configuration

What more can I do to fix this, how can I know what the problem is? I swear I'll give a <10€ game / prize to whoever helps me fix this, I'm getting real desperate

Thanks in advance
