Summary: While this device seems to work as I would expect in Access Point mode, my primary need was for it's WISP function to set up a LAN hosting an android tablet and Chromecast while providing WAN access through hotel wireless. I was successful in establishing connections to less than half the wireless acesss points that I tried while running the latest TP-LINK firmware version. Curious as to whether I had bad hardware, I flashed in OpenWRT.
Excerpt: - This is not a 3G/4G pocket router, in which you can insert a SIM card and make it work and you must already have a USB modem of your own to make this work. - When you insert your USB modem into this device, this then becomes a hotspot, which multiple people can connect to. - Lastly, it doesn't have a battery, which means that you will have to always have a power source (connect it to your laptop using usb cable or connect it to an electricity socket using an AC adaptor
Not compatible with Truconnect USB760 (If your USB stick is not on the compatibility list you are out of luck)
10 February 2013
Summary: Purchased this modem to work with an embedded device that requires Ethernet. Had had success with a Cradlepoint modem in the past and thought I would give this a go since the USB760 modem from Truconnect appeared on the "other" list on the TP-link site and the price was good. Truconnect is not an option in the TP-link settings for the USA region but the carrier they use (Sprint) is so I tried that.
Does not work with Verizon USB760 3G modem as advertised
4 February 2013
Summary: Though Verizon USB760 3G modem is listed as compatible it does not work even with the latest firmware. Switching from default configuration to manual advanced settings does not help either. Technical support is not able to provide any meaningful assistance. One example of the general sloppiness are the setup instructions that refer to a pin number that was supposed to be on the device label.
Excerpt: It is a nice product for home usage only. But it has limited range. It can not take place of other big routers. It can catch connection within 20 feet not more than that. Also recently I got a connectivity problem in device after upgrade of firmware succesfully. I have 3G data plan in my BSNL SIM and i use to insert my SIM in 3G dongle and that i connect in TP link Router. Now it is not working. It works fine in Mobile when i insert dongle or sim in laptop or Mobile.
Excerpt: This TP Link MR 3020 is a very small good looking product, easy to setup. Coins are -It works up to maximum 10 feet area, Internet speed through dongle is slow in compare to use direct dongle in laptop. Signal catching power is also not so good. My reliance net connect + Dongle works better in my apple laptop. I bought this product to use in my house , for using internet on laptop, tablet and phones. But its worst as its signal strength for reliance is not good.

Summary: As per TPlink website, the router is compatible with the Dlink dongle DWM156(see compatibility list for Singapore) or [...]. They also suggested to download and apply the corresponding file from the bin [...] in case it does not work even with the latest firmware. I tried all these combinations but nothing worked. The router could detect the dongle properly but while trying to 'connect' to internet, it is failing.
