Model: TL-MR3020  
Hardware Version: V3
Firmware Version: 3.20

Hallo, 

 

i´ve got a problem with the MR3020. It does not route DHCP-Requests to a subnet, when in bridge-mode. 

 

 

My Setup:

 

 

1. Main-Router (192.168.0.1)

2. MR3020 with "AP"-Switch and on reapter/bridge-mode (192.168.1.1) and DHCP-Relay (192.168.0.1) 

3. MacBook with cable connection to the MR3020 (EDIT: and Network mode for the Iface: DHCP with manual IP -> and then manue. adjusted address)

 

 

My goal:

 

The Macbook should be connected via the MR3020 in the same subnet like all the other devices, which are connected to the Main-Router. And that should work with DHCP.

 

What i discovered:

 

When i plug in the Macbook into the MR3020 it doesn´t get a DHCP IP-Address. Then i adjust the address manualy to 192.168.0.XXX to match the subnet of the Main-Router and it works. I can access Internet and i can be seen from the Main-Router subnet. 

When i adjust the address to the 192.168.1.xxx subnet, i can access the MR3020 like planned. 

 

My Problem: 

 

The Macbook can´t get a address via DHCP. 

 

PLEASE HELP ME! :D

When in AP mode the MR3020 should be in 192.168.0.X (same as main router) network to be able to handle DHCP requests from your laptop.

@Ivaylo 

 

I´ve got the router now with static ip address : 192.168.0.2 (and cut it out of the DHCP range of the main-router)

 

Still no DHCP. 

 

If i turn on the Mac iface to "DHCP with manual address", i can give it a manual IP-Address and the rest is set automaticly. But i have to give it an IP-Address. 

 

I wonder if this router is capable of this method of Client-Bridge with DHCP support?

@ArvidSmartHome 

 

Here's the device manual.

What are you trying to achieve: 2.2.4 (AP) or 2.2.5 (Repeater/Bridge) mode ? I believe you are up to 2.2.5.

For the DHCP setting - if now you configure DHCP Relay - 192.168.0.1 and set Mac to obtain the IP address via DHCP, does this work like ytou wanted to ?

Thanks for your reply! And thank your for the manual. 

 

I checked all the options like you said and i´m in reapter/bridge-mode( 2.2.5.). 

Either DHCP "off" or DHCP in "relay" mode wont work. 

It just works, if i give the Mac a static IP. Then the subnetmask and Router IP is changed automaticly.

Well, I suppose there's nothing more we can do about it. If that setup suits you, you can leave it that way.

I´m a bit unhappy about the outcome, bc i thought with a brand new fw and device this should work (they sell it for bridging) but at all costs its ok for 20 Euro. 

I wont complain anymore, but i have to say that client-bridge is not doable with DHCP support in my case. And i tried several devises not just the Mac. 

 

Hope you have a great holiday! Stay Safe.
