MR600 V3 error code 1, Internal error
I bought a new MR600 V3, when setting it up only power and WiFi lights came on. I went into the setup but it gives a prompt saying error code:1 Internal error. I can click 'ok' and the message disappears. However, the modem is really really slow in responding, tells me there is no sim card (which works fine in my other modem). At the same time it does recognize the provider because it loaded a profile named Vivacom 1. Vivacom is my provider, I am in Bulgaria. The error message keeps popping up. Is the modem faulty? Should I return it or can I fix the problem somehow? Please advise.
