Asus router issues?

[Falenkor]

Hey guys, so I am trying to set up a Mifi 8000 tethered via usb to an ASUS 3100 Router for connection through the sprint network. The idea came here from over there on the reddit post(I will post a link to it) however for the life of me I cannot seem to get this to work out. Does anybody happen to have a solution to this? I first tried the 2.0 usb in the back it set it all up okay but then I just had no internet going to the computer and it kept telling me there was something wrong with the proxy. So I reread how the person on those forums did it and he mentioned to make sure you use the 3.0 usb in the front. So I switched to that and now I see this image below from the router where the dhcp does not function proper.

 

 so, after digging around a lot I noticed this seems to be a very common issue for asus routers? Is my unit defective or something? During this after a minute the 3.0 usb light shuts off and the ethernet/internet light stays red and then just says there is no connection to the usb 3.0 slot.

Using USB for a WAN connection on like any router is going to be hit or miss. The router's firmware needs to have this as an option. I only know of one router where this is an option. Thats the Synology RT2600 AC. Im sure there are others, but this is not a STANDARD option you are going to find on most routers.

asus routers appear to have this capability just fine on quite the few of their routers though. Unsure as to why I am having this issue and how to solve it.

Just because some have this capability, doesn’t mean all. You will need to review the spec sheet to make sure.

Yes, I have done this already.. the router states it has the firmware to do this... Hopefully someone can actually help me.. thank you though. 

 

I have gone ahead and ordered a replacement usb-c incase this is faulty. A powered usb hub in case there's not enough power. along a replacement router as I am suspicious that the router may be defective. The router upon reboot will have the 3.0 light turn on itll connect to the mifi 8000. It starts with a dhcp error given a minute it will then say disconnected and given a minute after that it actually will say its connected just fine.. however within about 10 seconds after that it suddenly loses connection completely and the 3.0 usb light shuts off and doesn't come back on. I did manage to have it gain an internet connection just once.. so I feel there may be a faulty connection or defect somewhere as when the internet worked that time it actually stayed working the whole time it didn't shut off however I wanted to try to replicate whatever I did that caused it to start working though to no success and now cannot replicate it at all
