=====Free up more resources and tweaks=====
Remove some GUI items that we are not going to use:
<code>sudo apt-get remove dbus x11-common midori lxde python3 python3-minimal lxde-common lxde-icon-theme omxplayer raspi-config
sudo apt-get remove `sudo dpkg --get-selections | grep -v "deinstall" | grep x11 | sed s/install//`</code>
These are a big resource hog.

You also need to edit a boot file to slow down the USB hub so packets do not clash:
<code>nano /boot/cmdline.txt</code>

Add these two lines
<code>dwc_otc.speed=1
smsc95xx.turbo_mode=N</code>

The first one puts the USB hub into 1.1 mode.  the second slows down the usb side of the network.
