I bought the T
P-LINK TL-MR3220 and have the
Cell C ZTE MF668 USB modem. I have just got it to work now, but initially it didn't. The salesperson said to just upload the latest firmware....
The TP-Link website said that my modem was supported, for my current firmware but on first time insertion, the USB modem was not identified. I had a look on the website, and saw that there was a latest firmware download at
http://www.tplink.com/en/support/downloadFiles.aspx?mid=01030302&version=v1&pmodel=TL-MR3220
Uploaded the firmware, but modem still not identified. I emailed TP-Link and they asked me to send this command via HyperTerminal (Windows XP) to the modem on it's com port (seen under control panel/modems) with this command:
AT+ZCDRUN=8
(this allows the modem to auto start)
I restarted the router, with modem inserted, and the modem was identified correctly and I can connect. I also manually entered the APN settings to connect to Cell C.
HyperTerminal settings:
You need to set your connection to echo commands locally with ASCII Setup - "Echo type characters locally" or you won't see what you type.
The new connection you make in HyperTerminal should be set to Bits per second: 115200
DataBits: 8
Parity: None
Stop Bits: 1
Flow Control: None
Put the modem into your computer (make sure no other connection starts. If so stop the Cell C connection manager). Connect with your new HyperTerminal connection and then type in the command AT+ZCDRUN=8 and press enter
Then disconnect the HyperTerminal Connection and close. But the modem in your router and wait a few seconds for it to be identified.
I hadn't tried the MF 190 modem bin file.
Hope this all helps someone
