If you can browse the web normally but:
*
Windows Update doesn’t work
*
You can’t ping anything
*
Date/time won’t sync
*
Troubleshooter says “DNS server isn’t responding”
…then this is almost always a **system-level networking issue**, not a real internet outage.
Since you're on **Windows 7**, here are the most likely causes and how to fix them.

##
1. Proxy Settings (Most Common Cause)
If your browser works but Windows system services don’t, your browser may be using a proxy while Windows itself is not.
### Check this:
1. Open **Internet Options**
2. Go to **Connections → LAN Settings**
3. See if **“Use a proxy server”** is enabled
If it is:
* Either disable it
* Or make sure it’s configured correctly
Then also check system proxy:
Open **Command Prompt as Administrator** and run:
```
netsh winhttp show proxy
```
If it shows a proxy configured, reset it:
```
netsh winhttp reset proxy
```
Reboot and test again.

##
2. Corrupted Winsock / TCP Stack
Very common in older systems like Windows 7.
Run these in **Command Prompt (Admin)**:
```
netsh winsock reset
netsh int ip reset
ipconfig /flushdns
```
Then restart your computer.

3. IPv6 / Adapter Misconfiguration
Sometimes Windows services try IPv6 first and fail.
Go to:
* Control Panel → Network and Sharing Center
* Change adapter settings
* Right-click your connection → Properties
* Temporarily uncheck **Internet Protocol Version 6 (TCP/IPv6)**
Reboot and test.

##
4. Malware / Leftover Firewall Drivers
Even if you uninstalled your firewall, its network filter drivers may still be attached.
Go to:
* Adapter Properties
* Look for anything like:
* Old firewall filter drivers
* Security software network filters
Uncheck them temporarily and reboot.
If this machine hasn’t been scanned recently, run a malware check.

##
5. DNS Server Manually Set to Something Invalid
Check your adapter properties:
1. Adapter → Properties
2. Internet Protocol Version 4 → Properties
Make sure it’s either:
* Obtain DNS automatically
OR
* Set to valid public DNS like:
* 8.8.8.8
* 1.1.1.1
---
##
6. Corrupt Windows Services
Check these services:
Press `Win + R` → type `services.msc`
Make sure these are running:
* DNS Client
* Windows Update
* Network Location Awareness
* Windows Time
If any are stopped, start them.
---
##
7. Date/Time Failing = Deeper System Issue
If Windows cannot:
* Sync time
* Reach update servers
* Resolve DNS
* Ping
…but your browser works…
That strongly suggests:
* Corrupted system networking components
* Or Windows networking services broken
* Or a proxy interception scenario

Quick Most-Likely Fix Order
Try in this exact order:
1. `netsh winsock reset`
2. `netsh int ip reset`
3. `netsh winhttp reset proxy`
4. Reboot
5. Check DNS set to automatic
---
* What browser works?
* What happens when you ping 8.8.8.8?
* What happens when you ping google.com?
That will narrow it down immediately.
I just shared my thoughts, good luck.
