I'm a brand new Linux user. I installed it on an old Windows 8.1 machine. Wireless Internet will be connected for a minute or two, then I will not be able to load Web pages. I tried installing Wicd Network Manager, but it didn't remedy the problem.

You need to get an updated driver, with an internet connection do:
sudo apt-get install --reinstall linux-headers-$(uname -r) linux-headers-generic build-essential git dkms
git clone https://github.com/pvaret/rtl8192cu-fixes.git
sudo dkms add ./rtl8192cu-fixes
sudo dkms install 8192cu/1.9
echo "blacklist rtl8192cu" | sudo tee -a /etc/modprobe.d/blacklist.conf
Reboot

Run the command iwconfig
Find what your wireless connection name is and run sudo iwconfig wlp3s0 power off
Example:
ee@sys6:~$ iwconfig
wlp3s0 IEEE 802.11abgn ESSID:"5ghz"
Mode:Managed Frequency:5.805 GHz Access Point: E0:3F:49:93:3F:14
Bit Rate=390 Mb/s Tx-Power=22 dBm
Retry short limit:7 RTS thr:off Fragment thr:off
Power Management:on
Link Quality=57/70 Signal level=-53 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:74 Missed beacon:0
lo no wireless extensions.
enp4s0f2 no wireless extensions.
