AP-Client bridges WLAN and LAN

Hello!

I'm new here. I spent a lot of time with your search engine but I didn't find any answer to the problem I'm going to present. However, if you discover that my topic actually does duplicate another thread, please, refer me to the right place and don't scold me

I'm testing the ap-client mode in AirLive Air3g. The situation looks as follows:

ISP ---- D-LINK DIR-300 (Router Wi-Fi) -----> AirLive AIR3g (AP-client) ----->laptop

DIR-300:
DHCP: ON (192.168.0.100 - 192.168.0.150)
IP: 192.168.0.1
SUBNET MASK: 255.255.255.0

AIR3g:
DHCP: ON (192.168.1.100-192.168.1.150)
IP: 192.168.1.254
SUBNET MASK: 255.255.0.0

Laptop: automatic configuration

When the connection between ap client and router is made, AP-Client connects to DIR-300 (which I can see in the log) but does not receive an IP address. However, DIR-300 can see my laptop and assigns an IP address to my laptop. Consequently, my laptop has a 192.168.0.x address and sees all computers that are in the WAN network. The AP-client device disappears (for its IP is in a different subnet) and the connection to the internet from the laptop is really slow. To make sure that Wi-Fi isn't playing tricks on me, I disabled the Wi-Fi card and used only ethernet connection between the laptop and the AIR3g. Does anyone have an idea what's wrong and how to fix it?

If I'm not mistaken, ap-client mode shouldn't bridge WAN and LAN, should it? I experimented with the IP address of the AIR3g. I changed the address to 10.10.0.1 and DHCP to 10.10.0.2 - 10.10.0.50. Still, my laptop "reads" the configuration from DIR-300 and gets and IP address from there. If I set-up a static IP on my laptop (192.168.1.x), I can see the AP-CLIENT device but there's no connection to the internet.

Thank you in advance for helping me!

this is based on DD-WRT firmware, but the principles are the same

you can set it up as a gateway or a router.

client bridge / gateway makes two physically separate networks one big network with the same address scheme

client bridge / router connects a different network with different addressing scheme to your network

so:

my house to my motorhome: client bridge / gateway in the motorhome. both networks 192.168.1.XXX. one IP for the client bridge.

my house to my neighbors internet connection: client bridge / router. His side 192.168.0.1; my side 192.168.1.XXX. He only sees the IP on his side of my bridge, I see an address in the 192.168.1.XXX range.

Hi! Thanks for the answer!

I understand what you mean but maybe I was not clear enough.

Air3g is working in the ap client mode with DHCP on and hence it should create its own subnet and the laptop should take an IP address from Air3g, not from DIR-300. Also DIR-300 should see neither the laptop nor any other device from the other subnet.

The problem is that Dir-300 sees through Air3g which should not be possible. I'm not going to bridge the two subnets. I want Air3g to work as a normal AP client. In other words, Air3g behaves like a bridge, although AP-client mode is on. What disturbs me is that the connection from the laptop to the internet is 5 times slower than in the case of any other device connected via wi-fi directly to DIR-300. Could you please help me figure-out what I'm doing wrong?
