Some routers when they lease an IP to a device (thr' DHCP), they lease it
for 24 hours (default setting). Hence early in the morning, the first 254
people (xxx.xxx.xxx.2 to xxx.xxx.xxx.255) can connect easily while others
who shall come later during the day will have difficulty to get an IP
(since all slots have been leased).

The simple solution is to modify this parameter (via the admin of the
router) and enable only 1 hour lease for an IP. After 30 minutes, the
devices shall get a new IP in case they are still connected, or if they are
gone, IP slots can be freed.

Example (taken from Google search):

Static IP is a solution IMHO, but not everyone will be able to do this and
is not practical for the public.
