Hi, @Oma,
Thanks for your message. Although the +2 modem has an internal router, it’s not ideal for that speed; that’s why you received the extra router (Aria).
When the modem is connected to the Aria router, it is automatically set to bridge mode. In other words, the modem stops its internal router and the Aria router takes care of that job.
If you have your TP-Link router working ok and want to use only this one, you can disconnect the Aria router from the modem.
I’ll investigate that error with the My Viasat app, but before I need your account number. I could not find your account details based on your email, so I’ll send you a direct message so you can provide your account number.
Thanks!
