  1. Hi all,
    Great site, very informative, Thanks.
    I have an issue with a B593s-22 that was fine until I removed the sim card to top it up. Now it shows as disconnected Connection failed with error code 8609 and when that’s clicked a new window pops up with ‘A problem has occurred in the communication between your router and the wireless network. Please provide the customer support for the following information.
    Code: 0X0000021A1
    Details: loss coverged’
    There is zero bars but the sim card works fine in my phone so I’m stumped and would appreciate if anyone can offer any insight or advice. The APN is correct for the sim I’m thinking that perhaps it’s a hardware issue or maybe the MAC has been blocked.
