I should start out by saying that the internet works at the university (we use Resnet), and that when I bring it back home and put in my cable, it doesn't work.

Windows reports that my laptop is connected to the internet, it's just that any attempt to go on any webpage or to ping even the router results in a timeout.

It's not that my router isn't accepting pings, I ping the LAN (not WAN) address () and I get no response.

I attached the result of an ipconfig /all:

In addition, in an attempt to repair the connection via windows results in a message "WIndows could not finish repairing the problem because the following action cannot be completed: Renewing your IP address.

And the 'packets received' in the tcp/ip window are abnormally small.

If anyone has any insight into this issue, please help. No internet on my laptop is driving me crazy. Thanks.

Both and hit two of the most common angles: software blocking (firewall/proxy) and address assignment (DHCP vs static). The following is a compact, ordered checklist and a few concrete diagnostics that separate a local laptop problem from a router/ISP problem without repeating the information already posted.

Recommended quick checks (in roughly this order): confirm whether other devices on the same LAN get normal access (isolates router/ISP vs the laptop), verify the physical link (LEDs, try another cable/port or the same network on Wi‑Fi), and confirm there is no manual proxy or persistent third‑party firewall/AV rule interfering with connections (temporarily disable them only for testing).

Recommended diagnostic commands (run from an elevated Command Prompt). These focus on the local TCP/IP stack, routing and proxy state:

ping 127.0.0.1
arp -a
route print
netsh interface ip show config
netsh winsock reset
netsh int ip reset
netsh winhttp show proxy
tracert 8.8.8.8
nslookup google.com

What to look for from those results: a working loopback ping shows the TCP/IP stack is present; route print / interface ip show config will reveal whether the adapter has a DHCP lease or a static address and whether a default route exists; arp -a can confirm whether the gateway MAC is visible; winhttp show proxy reveals system proxy settings that browsers might inherit; winsock reset and int ip reset are low‑risk repairs for a corrupted stack. tracert and nslookup separate routing vs DNS failures.

If the router/ISP works for other machines but the laptop fails: remove any third‑party firewall/AV, boot Safe Mode with Networking and retest, uninstall and reinstall the NIC driver via Device Manager, and check adapter power‑management settings. If the router needs static addressing (per ), ensure the laptop’s adapter matches the required values. If the router blocks by MAC or has DHCP disabled, adjust the router instead of the laptop. Caution: disabling security software is only for short tests; re-enable it after diagnostics.

Check your firewall settings, make sure that your ip address is an trusted/accepted ip add. And make sure to setup your notebook with the specs of your home network.

does your network use fixed IP adresses or DHCP?
