Windows 7 no connection, WWW or Email, even though Network Xtion shows plenty of traffic

[glennnall]

i've been using a wireless connection successfully until i just moved. newly relocated, i am now using my T-Mobile Hotspot successfully.

i've attempted to connect via Cat5e to my roommate's modem and get no visible traffic (404 error, no Outlook Send/Receive).

i also connected to my roommate's wireless successfully, in that the WEP password let me connect, AND my firewall and Network Properties shows plenty of incoming and outgoing traffic - nevertheless i'm still unable to view websites and collect email.

i can't work off my phone - plus i'd like to learn what i need to know to troubleshoot this networking issue - can someone please lend a hand?

very grateful,
Glenn

Glenn, it seems like you are facing some connectivity issues with your newly attempted wired connection and the wireless connection at your roommate's place. Here are a few troubleshooting steps you can try to resolve these networking problems:

Troubleshooting Steps:​

1. Check Physical Connections:
   • Ensure that your Ethernet cable (Cat5e) is securely plugged in at both ends (your PC/laptop and the modem/router). Try using a different cable to rule out any issues with the current one.
2. Restart Devices:
   • Power cycle your modem and router. Turn them off, wait for a few seconds, and then turn them back on. This can sometimes resolve network-related issues.
3. Check Network Configuration:
   • Make sure your network settings (IP address, DNS server, gateway) are configured correctly. You can try setting them to automatic (obtain an IP address automatically) to see if that helps.
4. Disable Firewall/Security Software:
   • Temporarily disable your firewall and security software to check if they are blocking your network access. Sometimes, overly aggressive security settings can hinder network traffic.
5. Flush DNS:
   • Open Command Prompt as an administrator and type ipconfig /flushdns to clear the DNS resolver cache. This can help resolve DNS-related issues.
6. Check Proxy Settings:
   • Make sure there are no proxy settings configured on your browser or system that might be affecting your ability to browse websites.
7. Update Network Drivers:
   • Ensure your network adapter drivers are up to date. You can either download the latest drivers from the manufacturer's website or use Windows Update to check for driver updates.
8. Reset TCP/IP Stack:
   • You can reset the TCP/IP stack by running the following commands in an elevated Command Prompt:

      netsh int ip reset netsh winsock reset

     If these steps do not resolve the issue, there might be some deeper network configuration problems that need further investigation. Feel free to provide more details if you've tried any of these steps or if you encounter any specific error messages. That way, I can offer more targeted assistance to help you get your network connection back up and running smoothly.
