Hello I am working with Cisco packet tracer. I have two laptops connected to a wireless router with IP addresses assigned using DHCP. The router's Internet IP address is and the LAN address is I have an image below to for visual. enter image description here Here Wireless Router0 is the one with the IP addresses I specified above. Also on Router0 I have set the IP address on the port on which Switch0 is connected to I want to make a ping request to PC0 from Laptop0 . When I do, I get request timeouts, that is 100% packet loss. I want to know also that how would I access Laptop0 from PC0.

    Please update your drawing to include the address of all the router interfaces. BTW, if you're using a 24-bit mask, is an invalid address.

  • you should use access point instead wireless router and then set IP address for laptop and computer in the same range and then ping one of them. Feb 10, 2021 at 23:41
  • assigned using DHCP - where's your DHCP server? The laptops only get a DHCP config accidentally because you've used a wireless router instead of a more reasonable WAP.

well in the current settings they will never Ping each other because every single system is in different network, to make them ping you need to get all the systems to a single network or dual network connected to a single node. Explaining it Below

First I can see 3 different networks and apipa network, so now go to the settings of the wireless router 0 and turn of the DHCP in the wireless Router0.

next the cable which is coming from switch 0 and plugged in wireless router 0 check if it is plugged in lan port or internet port? i am pretty sure it is plugged in on the internet port so remove it from there and plug it into the lan port of the wireless router 0 (Any Lan port i think its color is yellow hola)

The Above steps will give your laptop an ip of your main network and your router can now ping your router 0 .

next step (left side cleared now the right side)

now in the Right side its pretty simple your pc's are not getting the ip address from the router 0 so there is a mistake in your DHCP setting so change it if possible or delete it and create a new one. once your pc gets the ip from the DHCP then yes you are coonnected to the network and boom you will get the ping.
