Def E180 modem. firmware is the latest one currently on their site TL-MR3420_v1_110617 . Modem works great in my pc(although it only connects on 2nd redial-every time. i get a error 619). Router gets a connection if i leave it over night. I've set it to automatically connect with idle time set to 0. Once connected it works great and i haven't had a dropped connection.
I've got the E1820 and the MR3420 - the router generally picks up the modem within 5mins, but sometimes takes ages to log onto the Cell C network
