Recently purchased a T-mobile LINKPORT IK511 (given their $10/month MI30TI plan).
My intention was to plug it into my RT-AX88U Pro, enable dual WAN, and use it as a fallback for when/if my wired fiber internet ever goes down.
Without messing with any settings, I went ahead and plugged it into the USB port. It was immediately recognized (see screenshot). I then went to the USB modem settings and also didn't change anything (screenshot).
I manually configured my dual WAN settings to look like the screenshot below.
When I pull the plug on my wired fiber internet, the Backup Wireless Modem goes from "Cold-Standby" to "disconnected". It cannot get a WAN address from the T-mobile modem.
The LINKPORT IK511 does have a GUI where you can enable IP Passthrough as an option. After trying that, same result. I cannot seem to get a WAN address from that modem. I found a reddit post with someone who claimed it worked:
I guess I am trying to determine if what I am doing is doable... or if this is a pipe dream. Anyone else try this with a USB modem?
