Hi,

What is the light status of the 855RE? 

Do you use  the home wifi password to configure this range extender? 

Meanwhile, please refer to the instruction below  to do further analysis.

Hi Kevin,

so, the light is all good, blue and working normally and about the password, yes, i use the same password for the range extender, the same as my modem is.

This link that u send, my problem is like the Case 3, i connect but seems not to have internet, but, if i connect directly to my modem the internet working.

The problem occurs sometimes, like now, is working normally.

Hi,

Thanks for your reply; 

So the 850RE works fine but sometimes there is no internet access from it? 

With your computer connected to the 850RE but no internet access, what is the IP address and gateway obtained?

Can you ping the gateway of the main router at that point? 

What is the current hardware and firmware version of the 850RE? 

Meanwhile, if there is no internet from the 850RE, with your device connected to the main router directly, can you get internet? 

Thanks in advance, and have a nice day.
