Solved: Re: Unable to ping after Wireless Configuration using (WRT300N)

HeroVax · ‎06-18-2022

Hello, I have issues with my PC cannot ping to the Internet as well as other PCs. It says "Destination Host Unreachable".

Currently, my plan is to create a DHCP Pool using WRT300N Wireless Router. The PC VLAN Security, will then able to access to the Internet and its peers via Wireless LAN that I made using that router. However, it does not ping as I intended.

Also, the Wireless Router continuously denying my settings and it keep changing my DHCP pool. Example shown below:

I want my DHCP Pool range between 15.0.4.131 - 157. But, whenever I save settings, it automatically changed to 15.0.4.129 - 157 range.

I have set up the Router-on-a-Stick for VLAN 40 Security on Router KL. It uses IP Address "15.0.4.129 /27". So, I set up my wireless router as "15.0.4.130 /27".

I have attached my pkt file inside the zip file below for your reference. Thanks.

I change the transit network between WRT and router to 192.168.11.0/24 because you already have the network 192.168.10.0/24 in Penang. It was causing conflict.

The changes I made:

KL:

The interface GigabitEthernet0/0/0.40 is also using ip address 15.0.4.128/27. So, it was conflicting with wireless network. I disabled it.

Once we disabled it, the network 15.0.4.128 is not advertised anymore to the router Penang.

If fixed that by adding a static route on KL:

ip route 15.0.4.128 255.255.255.224 192.168.11.4

Then, on the OSPF I added:

router ospf 10

redistribute static subnets

This way, the network 15.0.4.128 was sent to Penang and connectivity started to work.

Let me see if you are ok with that and let´s see next steps
