Nighthawk X4 AC2200

Just got this Nighthawk range extender and I've tried everything in the manual to connect to my router with no luck.

 

1) Tried WPS by pushing the WPS button on my Hitron router and the extender (switch set to extend not access point). Didn't work.

 

2) Plugged an ethernet cable from the extender directly into my computer and my computer connected to my router via wifi. Got the new extender setup page, went through everything and even double checkied my router password. Failed to connect in the end.

 

After that I used a paper clip to reset the extender and tried the above 2 steps again. Ended up doing a reset 3 times and going through all the steps again and again.

 

Tried connecting at 2.4G only and then 5G only and both. Nothing worked.

 

After 4 hours, I did notice that when using the wired connection setup, the extender scans and sees my router using TKIP encrytion. My router only uses AES and there's no other option to change it to TKIP.

 

I can't find anyway in the extender setup menu to change it to AES.

 

The extender is less than 6 feet from my router; it's broadcast power is set to 100%. My wifi network analyzer says the signal strength for the router and the extender are about the same and they down out the neighbours.

 

Does anybody have any suggestions other than what it says in the manual or have a way to force the extender to recognize my router encrytion as AES?

 

Thanks for reading and any helpful suggestions.
