Wow! Thanks for the opportunity boss.
This problem is caused by dhcp pool depletion. No Ip addresses available for new devices. The solution is to Clear IP DHCP lease table and reduce the dhcp lease period from 3days to 1day.

Yelutide, congratulations!!! You correct provided the first working solution. Please reply the email sent to you with your preferred shipping address.
The problem could be from multiple scenarios. Network administrator in this case may have configured Mac Authentication using Access List, limit dhcp address pool, or possibly must have set ARP to reply only.
Solution….to resolve this depends on the network admin policy. The network admin may review access list policy to accommodate new users based on policies addresses above or manually add the new devices and grant them access /previledge.
Hell Ojo, your answer shows you are an experienced network engineer/admin. However, limited dhcp pool is responsible for this. Mac filter and arp reply only configured by an administrator wouldn’t be a problem to same admin since the features were implemented by him/her.
All the same , I would have considered your answer if it was the first. I wish you better luck next time.
Thanks Timi I did mention limited dhcp pool too in my response. However my comment came in late. Thanks for your valuable inputs to the discipline of network engineering. I have learnt a whole lot from your blog and do not mind an internship even if unpaid under you to help me develop already existing skill sets. Can I speak with you privately if such an opportunity is available in PH or Lagos?
Thanks Ojo I will send you a mail.
Hi Timi,
Can one see other comments from other users on this blog? I can’t even see my earlier comment for the give away.
The problem may have been caused by an ARP issue. Old devices may have been manually added to the ARP table and WLAN interface’s ARP settings may have been set to reply-only.
To correct it, MAC address and the IP address of the new devices must be added to the ARP table.
Hello Timigate
I think the problem in the new device is ip configuration. For an example, old device use DHCP Client, new device still static IP but without gateway.
.
Or maybe DNS or something
.
So he should change an ip address to DHCP or use static but put gateway and DNS
.
Thank you
Another possible reason. However , mobile devices like phones and tablets have their IP address settings set to automatic by default and could not have been changed on all new devices.
