Hi,

If your Odoo website is loading slowly on office and home Wi-Fi networks but loads quickly on mobile data, there are several potential reasons for this discrepancy. Here are some possibilities to consider:

1)There may be network configuration issues specific to your office and home Wi-Fi networks that are affecting the performance of your Odoo website. This could include network congestion, bandwidth limitations, or restrictions imposed by firewalls or proxy servers.

2)The settings on your Wi-Fi router at your office and home could be impacting the performance of your Odoo website. Check for any QoS (Quality of Service) settings that may prioritize traffic differently or any security settings that could be blocking or throttling access to certain websites or services.

3)There may be heavy local network traffic on your office and home Wi-Fi networks that is impacting the performance of your Odoo website. This could be caused by other devices on the network consuming bandwidth 

4)Weak Wi-Fi signals or interference from nearby devices or obstacles can degrade the performance of your Wi-Fi network. Ensure that your Wi-Fi router is positioned optimally and consider using Wi-Fi extenders or repeaters to improve coverage.

Hope it helps
