Hi  @DilipPandey 

What kind of users are not getting Internet access?

Below is a structured troubleshooting steps:

1. Check Basic Connectivity**
- **AP Status**: Verify the AP is online and broadcasting the correct SSID.
- **Router/Modem**: Ensure the router/modem has an active internet connection (test with a wired device).

**2. DHCP & IP Address Issues**
- **DHCP Scope Exhaustion**: If the DHCP pool is too small, some devices may not get an IP.  
  - **Fix**: Expand the DHCP range (e.g., from `192.168.1.100-192.168.1.200` to `192.168.1.50-192.168.1.250`).  
- **IP Conflicts**: Two devices with the same IP can cause issues.  
  - **Fix**: Restart the DHCP server or assign static IPs to critical devices.  
- **Check Device IPs**:  
  - **Working Devices**: Should have a valid IP (e.g., `192.168.x.x`), subnet mask, gateway, and DNS.  
  - **Non-Working Devices**: If they have an APIPA address (`169.254.x.x`), DHCP is failing.

**3. Client-Side Issues**
- **Wi-Fi Signal Strength**: Weak signals can cause intermittent connectivity.  
  - **Fix**: Move closer to the AP or reduce interference (e.g., from microwaves, other networks).  
- **Device-Specific Problems**:  
  - **Fix**: Restart the affected device, forget and reconnect to the network, or update drivers/firmware.  
- **MAC Filtering**: If enabled, ensure affected devices are allowed.  
- **Band Steering**: Some dual-band APs may misdirect clients (e.g., to 5GHz with poor signal).  
  - **Fix**: Disable band steering or manually connect to 2.4GHz for better range.

**4. AP/Router Configuration**
- **Maximum Client Limit**: Some APs limit concurrent users.  
  - **Fix**: Increase the limit or upgrade hardware.  
- **QoS/Throttling**: Check if traffic shaping is blocking certain devices.  
- **VLAN/SSID Isolation**: Ensure users are on the correct VLAN/SSID with internet access.  
- **Firmware**: Update the AP/router firmware to the latest version.

**5. DNS Issues**
- **Non-Working Devices**: Try pinging `8.8.8.8` (Google DNS).  
  - **If ping works but no browsing**: Set DNS manually (e.g., `8.8.8.8`, `1.1.1.1`).  
  - **If ping fails**: Gateway/DHCP issue.

**6. ISP or Firewall Restrictions**
- **ISP Throttling**: Some ISPs limit devices per connection.  
  - **Fix**: Contact ISP or use a different router.  
- **Firewall Rules**: Check if the AP/router is blocking certain MAC/IP ranges.
