Re: Continues drops on 3G

[Jonathan Petersson <jpetersson garnser se>]

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.
