If an Ubiquiti UniFi AP is syncing with the controller but the link isn’t working (no connection to the network), it usually indicates a problem with the physical connection or the AP’s network configuration. Troubleshooting steps include checking the physical link, verifying the AP’s IP address and subnet, and ensuring the controller can reach the AP.

In the context of Google Sheets, “ping” can refer to two different functionalities: tagging users in comments or cells, or freezing rows/columns to keep data visible while scrolling. It can also refer to using Google Apps Script to check the availability of a network endpoint, like an IP address. Tagging Users (Like “Ping” in Social Media): You can tag users in Google Sheets to notify them about a specific cell or comment. To tag, type the “@” symbol, then start typing the name or email of the person you want to tag. A list of potential users will appear, and you can select the one you want to tag. Freezing Rows or Columns: Freezing allows you to “pin” data, keeping it visible on the screen even when you scroll. This is useful for headers or data that you need to refer to constantly. To freeze, go to “View” > “Freeze” and choose the number of rows or columns to freeze. Using Apps Script to “Ping” IP Addresses: You can use Google Apps Script to check if a specific IP address is reachable, essentially “pinging” it. This involves writing a script that sends an ICMP request to the IP address and checks for a response. The script can then populate a cell in your sheet with a “True” or “False” value, indicating whether the address is reachable. Example of using Apps Script to ping: function pingIpAddress() { // Replace 'A1' with the cell containing the IP address you want to ping var ipAddress = SpreadsheetApp.getActiveSpreadsheet().getActiveSheet().getRange("A1").getValue(); // Check if the IP address is reachable var url = 'https://ipinfo.io/ip?token=YOUR_TOKEN'; // Replace YOUR_TOKEN with your ipinfo token var options = { 'method': 'get', 'contentType': 'application/json' }; var response = UrlFetchApp.fetch(url, options); var json = JSON.parse(response.getContentText()); var ip = json.ip; SpreadsheetApp.getActiveSpreadsheet().getActiveSheet().getRange("B1").setValue(ipAddress==ip?"True":"False"); }

“AirView is disabled because DFS Pre Scan is active.” ⸻ 🔍 What it means: This message appears when your device (typically a Ubiquiti AP or other 5GHz Wi-Fi device) is operating on a DFS (Dynamic Frequency Selection) channel. DFS channels require your device to scan for radar signals before broadcasting — this is called a DFS Pre-Scan. During this scan, certain features like AirView (the spectrum analyzer) are temporarily disabled. ⸻ ✅ How to fix it: Option 1: Wait for the DFS Pre-Scan to finish • The DFS scan usually takes 1 to 10 minutes. • Once it completes and no radar is detected, AirView will be enabled again. Option 2: Switch to non-DFS channels If you need AirView immediately: 1. Log in to your device or controller interface (UniFi Controller, or device Web UI). 2. Go to the Wireless Settings. 3. For the 5GHz band, manually select non-DFS channels only (like 36, 40, 44, or 48). 4. Save the changes. 5. Reboot the access point if needed. Note: DFS channels include 52–144. Non-DFS channels are safer for tools like AirView and provide instant startup without delay. ⸻ 🧠 Extra Tips: • In some regions, regulatory laws require DFS usage — disabling them may limit your frequency options but will keep tools like AirView available. • DFS is used to avoid interference with weather radar and aviation equipment. ⸻ Let me know your exact device model, and I can give you step-by-step visuals or configuration help if you’d like!

An ISP core network, also known as a backbone network, is a central part of a telecommunications network that connects and routes traffic between different parts of the network?

The error “TTL Expired in Transit” is a common issue in network troubleshooting, especially when dealing with routing problems. This message typically occurs when a packet exceeds the maximum number of hops before reaching its destination. In this article, we’ll explore what this error means, what causes it, and how to solve it on Windows 10 and routers, including Cisco devices. What Does “TTL Expired in Transit” Mean? TTL (Time to Live) is a field in an IP packet that determines the number of hops (routers or switches) a packet can traverse before being discarded. Each time the packet passes through a router, the TTL value decreases by 1. When the TTL reaches 0 before the packet reaches its destination, the router discards the packet and returns the “TTL Expired in Transit” error message. What Causes “TTL Expired in Transit”? There are several causes for this error, including: Routing Loops: If the network routes a packet in circles between multiple routers, the TTL count may reach 0, causing the packet to expire. Distance: The packet may need to travel through more hops than the TTL value allows, especially in larger networks or complex routing paths. Firewall or Security Restrictions: In some cases, security software or firewalls may interfere with TTL values and cause the packet to expire prematurely. How to Fix “TTL Expired in Transit” in Windows 10 Check Your Network Configuration: Incorrect IP settings or a misconfigured gateway could be causing routing loops. Run the Windows Network Troubleshooter to identify any configuration issues. Go to Settings > Update & Security > Troubleshoot > Internet Connections. Use the Tracert Command: To locate where the packet is being dropped, use the tracert command in Command Prompt. Open Command Prompt as Administrator and type:tracert <destination IP> This will show the path your packet is taking and where it might be getting stuck. Increase TTL Value in Ping: If the destination is too far or there are too many hops, try increasing the TTL value when using the ping command. Open Command Prompt and type:ping <destination IP> -i 128 This increases the default TTL value to 128. Check Router and Firewall Settings: Ensure your router isn’t blocking or manipulating packets’ TTL values. You may also need to check your firewall settings on your PC or network. Fixing “TTL Expired in Transit” on Routers (Including Cisco) Check for Routing Loops: Use traceroute on your router to identify any routing loops in your network. Cisco routers can run this command to trace packet paths: traceroute <destination IP> Review Routing Tables: Ensure the routing tables on your Cisco or other routers are correctly configured. Misconfigured routes can cause packets to loop. Adjust TTL Settings: In Cisco routers, you can use the following command to adjust the TTL value: ip ttl <value> This can help when you’re dealing with packets that need to travel through multiple hops. Network Monitoring: Regularly monitor your network for any unusual routing activity or loops using network management software. “TTL Expired in Transit” vs. “Request Timed Out” TTL Expired in Transit: This error occurs when the packet hits the maximum number of hops before reaching its destination. Request Timed Out: This error happens when a response isn’t received within the timeout period. It can be caused by network congestion, dropped packets, or firewalls blocking traffic. Conclusion The “TTL Expired in Transit” error is typically caused by routing issues, including loops or long paths that exceed the packet’s TTL value. To resolve this issue on Windows 10, routers, or Cisco devices, you can check your network configuration, use tools like tracert, and adjust TTL values. Monitoring your network for routing loops and ensuring proper configurations will help prevent this error from occurring in the future.
