Maybe a security problem involving Linux hosts

Hello,

with the following problem I feel helpless because I do not know where to look for the problem.
Sorry in advance for my poor English.

At some point the interaction with people on Freenode IRC has become mysterious and offending so that I checked my modem/router device. When I tried to make a change the modem gave me the error message that another admin is logged in. It alerted me because all other computers were disconnected. So I called my ISP and they agreed that my device is listed there at "being attacked". They sent me a replacement and they also sent me a new password.

With the new modem I booted a linux livecd that i got from a linux magazine. And from there I downloaded the ISOs and wiped all my machines using DBAN.

With all the people in my social environment telling me to relax, think positive and all that stuff like "its only your false perceiption on things" I stopped paying attention on mysterious errors, etc. Until I needed the Hexchat client to check a local ircd install. And it launched with 1 network added. I am absolutely sure I had 0 networks in that network list when I went on an IRC break. Several months before there was a similar thing where all 18 or 19 networks had their name changed to EF-Net.

Another thing is that I stored all my website passwords in Lastpass and when I went offline for 3 days to install and configure some things my passphrase was changed to the one I used several months ago and all my stored passwords were deleted.

I could provide several more of these stories.

I hope none of you guys reacts now how most people reacted: "this guy is crazy, give him more meds" or something. I know it sounds crazy and it is crazy. But lets say my observations are correct where could the entry point be for an attacker?

friendly Greetings,
SInt
