Fiber wifi problem

Hi I just want to make sure before I do anything, because everyone's situations are different. 

So I had read few forums about having different router, because ATT BGW210 would NOT cover a thing for my devices. 

I recently moved and my previous owner of the house had set the fiber at basement for some reason, so I cant use ethernet either.

and also I bought the nighthawk coverage expender, but its not doing much of the work because the modem of the WIFI is bad. 

and here is the questions.

  1. So I read few thing on google that say I could buy the router and connect with the "pass though mode". does this will affect on speed of the Wi-Fi? will it get faster? is there any possibility that ATT device does IP block? if its not possible, can i get any upgrade on router? the Gateway?
  2. Internet itself is just fine. they cover around 980~950 on income and outgoing internet. but after going thought the "home network hardware" it slows down to 200 (right next to the device). is it the modem's problem right? 

Thanks guys, please help :( its been real pain to do online class and games.

Here to help with your Wi-Fi, @Dopehoon21!


First, have you tried testing for weak Wi-Fi signal in your residence with our Smart Home Manager app? If not, that would be a good starting point so you can arrange your extender accordingly. You can also give this steps a try to optimize your internet connection as well.


Now, regarding your questions:

  1. Yes, you can buy a third party router and use our step-by step guide to set it up IP Passthrough to allow it to work properly with our service. When putting a device in IP passthrough, you will not affect the speeds of the Wi-Fi. Sometimes our device will block certain IPs, but you will need to verify that the device is being blocked.
  2. It's possible, but it can also be the Wi-Fi coverage in the residence.  We would have to run some test on our end to see if it's an actual issue with our equipment.

Give those steps a try and let us know the results so we can assist!
