I frequently use tethering/hotspot with my cell phone to connect my laptop to the internet when I'm working away from the office. I've been using this method for about two years. Initially, the connection was very fast, and at times, it seemed even faster than the regular connection in my office. However, lately, it has often slowed down to almost a standstill. Most of the time, it takes a few minutes just to load a webpage. What could be causing this slowdown, and what can I do to make the tethering/hotspot connection faster? My cell phone is android. I did change my laptop during this period. Could it be because of something related to the new laptop? Thank you in advance for your help.
