No insurmountable issues as of yet.

I have no real complaints about this router. Setup was a breezea and configuration options are plentiful. It strikes the perfect balance between customization and simplicity, meaning neither a techy nor non-techy person should have any trouble setting up a network. The only issue I encountered, and only once (so far) was possibly due to the carrier (T-Mobile via The Calyx Institute), where the internet connection simply dropped for about 15 min. Considering that a reboot of the router didn't fix the issue, I'm inclined to blame the carrier.

Fast, and portable

Good cellular internet. Connects to T-Mobile with 100 MHz of carrier aggregation. Could use a newer modem, but works great for what I bought it for!

Great travel or fail over router.
