"How can I remote into my computer in my apartment when the IP address keeps changing?"
This can be accomplished with something called Dynamic Domain Name Services (DyDNS or DDNS). For more information on how it works at IAS, go to https://www.ias.edu/ddns
"My Windows 10 laptop cannot stay connected to the wireless network in my apartment but I have no problems on campus or at the coffee shop"
There is a known driver compatibility issue between the latest Intel drivers and the latest wireless access points that IAS has been installing. The behavior is that the device gets an IP address but cannot access web pages or other network resources for long periods of time.
The problem is with how the VHT mode settings are processed. By switching the "HT Mode" from VHT to HT, the device is able to stay connected on the IAS's wireless networks. The device will continue to use its 802.11ac radio with its benefits.
