Summary: After a bit of a rocky start, setting up the 210 for Bigpond 3G internet using the Sierra 312U USB modem needed the very latest firmware that wasn’t shown on Deaytek website but I happen to find it in their FTP service. It takes about 2 minutes for the 210 and the Sierra 312 usb modem to ’match’ to each other. Once done all is good. Reasonable good WiFi range. It’s 30 meters from inside the house to the work shed. Upstairs signal is also good.
