Re: Continues drops on 3G



Hi Dan,

Turns out that my drive was crashing causing the whole system to be
unstable for some reason it started showing with the 3G modem dying,
buying a new drive and reinstalling the system solved the issue :)

Btw, as mentioned earlier I just got notified that my 4G modem is
ready for pickup so I'll try to get it sometime this week.
