At the college where I work, you get a maximum of 3 devices on the wifi. That may cut out a lot of nonsense.
After that, we are having lots of problems with online video classes cutting out. Not too many more details because I don’t handle that area, but there is normally an AP about every 20 to 30 feet. Some of that has changed because they pulled a bunch out of hallways and put extras in specific areas for people on campus to go if they have a video class. We have 1gb download and I think 1gb upload.
