My Z370, bought 2 years ago. The wireless works at home, and hotel when I was in business trip. But on campus, it cannot detect any WIRELESS connection now.
Originally, it can detect wireless on campus with very weak signal and it was always disconnected. So I used a wire for internet. But now, the wireless doesnot work at all, no connection can be found when I am on campus (in my lab, in my advisor's office,...etc.)
It's really frustrating when I meet with my advisor at that time he may send me some files but I cannot acess internet at all.

Welcome to the forum!
What I would do is remove the wireless card from the system and then boot the machine up without the card installed. Then shut the machine back off, re-install card and boot it up to see how it now performs wirelessly. This procedure would accomplish two things. First, it would re-install the card into the operating system thus eliminating the possibility of any glitches with its previous installation into the OS. Secondly, the removal and re-installation of the card would insure that it is properly seated and that all connections are making good contact. The whole procedure is relatively easy to do since the wireless card can be accessed under a panel on the bottom of the laptop. The downside is that when Windows re-installs the card you will more than likely lose all your previous saved wireless log-ins.
The link below is for the Hardware Maintenance Manual for your model in a .PDF format. Page #42 will explain how to remove the card and #43 how to install it. Be sure to follow any cautions in regards to static electricity, powering the system off and having the battery removed while working inside.
