Hi, thank you so much for your patience with my questions.
I am unable to get any connection at all when I try ttyUSB2. Whenever I try ttyUSB3 from the GUI page I get “device busy”. ttyUSB4 is the only “register” the sim and is able to get me to the scenario where I can get internet for a few minutes at a time. ttyUSB3 seems to be the only one i can send the AT commands from. Should I try resetting to original settings and try only using ttyUSB2?
I tried the TTL switch on both ttl = 64 and 65 but no luck
It is possible that the ISP is doing something to interfere with the connection because I have had problems tethering as well. I was hoping Cirrus would do better because it is a more direct approach similar to MoFi 4500 (which is working)
For 5 - Is the router firmware setting the at+cgdcont to a default value by any chance? I feel like my changes are working in the AT Commands but I cannot get connection just from AT commands, it only works after Modem Reset or hitting “Apply” from GUI page. I am wondering if resetting or applying changes reverts the value to some default.
Thank you again!!
