You’ve connected your Turkcell Vınn E176G to a 3G router like a TP-Link MR3420 or a Mac computer. But you don’t know which network you’re connected to. You can tell by the color of the LEDs on the modem.
The modem has two LEDs. One is green, the other is blue.
1. If the green LED is lit: You’re on an EDGE network. Slow internet connection.
2. If the blue LED is lit: You’re on a WCDMA network. Medium-speed internet connection.
3. If both LEDs are lit: You’re on a 3G network. Fast internet connection.
