What is the difference between the one you mention and this: https://www.amazon.com/GL-iNet-GL-MT300A-Pre-installed-Perfo...
Can I upgrade the antennas, do you know?
Edit: it looks like it can take PR-SMA female as a connector.
Mine runs OpenVPN in bridge mode to an SSID. I rarely use the ethernet. And I sometimes use the USB port as a charger. Having a usb cable connected to the wallwart makes it look like a charger. :)
Was also looking at the TP-Link TL-WR710N, but I preferred the more wallwart looking and slightly more compact D-Link. It does have an extra ethernet port if that's a requirement. TP-Link's locking down of thirdparty firmware also led me to keep the D-Link and return the TP-Link. I think they got better about that though.
