Failure to obtain IP address

Failure to obtain IP address
Failure to obtain IP address
2020-02-16 14:55:25
Model:Adapter
Hardware Version: V3
Firmware Version: 1.0.1 Build 20190124 Rel.56886

AC1750 wifi range extender

Model RE450

 

When the device was set-up with the same name as the host network, it worked fine.

As soon as I tried to give it a different network name, which I need to do, now none of my devices will connect to it.

When trying to connect to the extender network it says "cannot configure IP address" or "cannot obtain IP address".

 

I cannot understand why it was working fine, but just by changing the network name, now nothing can connect.

 

Please help.

Hello, what is the led status of the RE450 now? 

 

Try to forget the network and reconnect to the RE450's wifi; you can reboot the range extender as well. 

 

With computer connected to the RE450 directly, try to log into the web UI and show us a screenshot of the settings-status page.

 

Besides, please ensure that the firmware is the latest one. 

 

Good day.

Hello

 

The led status of the RE450 is good. All solid blue lights.

 

I did try to forget the network and reboot the extender, but this unfortunately did not help.

 

I have checked the firmware. It appears to be the latest.

 

I am now unable to log in to the web UI as I cannot connect to the extender. I have tried over wifi and ethernet. (Cannot obtain IP address)

The only way now that I can connect is by resetting to factory settings and then going through the setup process again.

 

But once it saves the new settings, then it kicks me off again.

 

Please see attached screen shot of settings status page.

Thanks for your valued reply. 

 

May I know what is the model number of the main router and its firmware version? If possible, please show us a screenshot of the device information about the main router. 

 

Meanwhile, you can reset the RE450 and re-login to configure it; then you can go to settings-network-DHCP server page to toggle on the DHCP server and setup a static IP which is in the same subnet with main router for it. 

 

May it help.

Thank you for your help with this.

The main router is a Mikrotek Routerboard hap ac lite.

Because it is supplied and managed by my service provider I am unfortunately unable to access the management page.

I do however have the IP address of the main router which is 197.245.146.143.

 

As you suggested I went into the settings-network-DHCP server page of the RE450 and I toggled on the DHCP server. I am however unsure how to setup a static IP which is in the same subnet with main router.

Is it possible that you could give me detailed instructions of what to put into the settings-network-DHCP server page? 

 

The support guy from my service provide says that he logged into the main Mikrotek router and gave the TP-link extender a static IP, which I asked him to do. Does this help at all?

Hello, you do not have to setup static IP for the RE450 on the main router. 

 

Below are the instructions:

1. Please connect your computer to the main router and click here to get the IP address and gateway. Or you can contact ISP to get the DHCP range and LAN IP of main router.

 

2. Then you need log into the web UI of the RE450; and go to settings-network page to setup the static IP and DHCP server settings.

 

Please notice that here we take 192.168.0.1 as an example; The actual default gateway is what you get from step 1, which is the LAN IP of the main router. 

3. After that, you can reconfigure the RE450.

 

Good day.

Hello, and thank you for your instructions.

 

I have competed as instructed.

 

The good news is that I was able to complete setup and rename the SSID and connect to the new extended network with all my devices.

The bad news is that it says "connected, but no internet".


Any thoughts?

 

Many thanks

Hello, there is something wrong. Please refer to the picture attached below:

 

Note: You wrote 192.168.101.158 as the static IP address of the RE450, so the IP address of your smartphone which connects to the main router should be the same subnet, which is 192.168.101.x, the x can be a number within the DHCP range.

Thank you for your help.

I am still not sure what I did wrong, but I have managed to get it to work, so thank you.

 

Attached is a screen shot of the settings that I put in.

 

Interestingly enough, the one thing I did differently this time is I did NOT click on the finish button at the end of the quick setup page. I almost feel like that was causing the problem? Not really sure though. But its working.

 

Have a great day further.
