This is screen you should see when you launch your browser at http://192.168.1.1/. The ‘off the shelf’

Scroll down the status screen and in factory default mode; the TL-MR3420 has already discovered the
MF 668 usb modem and is detecting signal. It is not yet connected. If you clicked ‘connect’ it may
attempt an automatic connect; however we will use the ‘Quick Setup’ for this.

Go to ‘Quick Setup’.
Click ‘Next’

If there is no ADSL connection this is what you will see. Click ‘Next’.
Here we setup the 3G connection. The router has many ISP configurations and it will probably get it
right, once you select your ISP. Note: Bigpond usb devices require a Username and Password.

Bigpond APN: telstra.bigpond. For manual setup of other ISP APNs visit this link. Click ‘Next’.
Here we setup the wifi security.
And we are done. Click ‘Reboot’.

The status screen is now showing ‘3G connected’.
Here is the zippy speedtest at Gorokan NSW, using a wifi connection to the TP-Link.

I then connected a 6 or so dB omni to improve the signal.
Using my Telstra T90 tuff phone connected to the antenna at this same location, it indicated 5 bars, and
these are the results from the engineering menu:
RSSI -69dBm
RSCP -68dBm
Ec/Io -13dB
The TL-MR3420 reading is 70-74%.

A more detailed signal strength status from the modem would be desirable; however given the
multitude of modems that this router works with; this may be a tall order.
From my brief experience to date, this is a great 3G router, fully of features and the price is right.
It supports the Telstra Ultimate (Sierra 312U) and TP-Link do respond to problem queries.
Important note: The latest firmware 110617 provides a major revamp of 3G functionality.
110617 Modifications and Bug Fixes:
Fix the wrong warning error of PUK Lockup.
Fix the 3G Page hangs problem. (additional connection configuration settings)
Fix some dial-up problems caused by pppd quit.
Add or modify the ISP list.
Improve the compatibility.
Add PIN authentication on the 3G Page.
IF your modem is already in use, this upgrade will delete your 3G configuration data. Via the
TPLink Menu, use System -> Backup prior and System -> Restore after upgrade, to store and
recover your router configuration settings.

This is how I have configured the 3G page for Telstra after the upgrade.
