17:18:55@thefrenchghosty:privacytools.ioTheFrenchGhostyGuys, since some days I have some issue with my laptop dropping connection for 1 seconds every minutes when I use it (it works correctly when idling even with the same softwares open) I don't know if this is my VPN or my laptop internal wifi adapter that broke. I tried to use to switch to multiples VPN servers and the problem keeps happening so I'm guessing that it's an issue with the adapter I had some (unrelated) massive connection issue for weeks before where the connection dropped globally every 30 seconds and since then this appeared so I suspect that this caused the problem, any idea how I can debug this? (mainly see what the kernel/firmware see when the connection drop)

You could use Wireshark if all else fails. I'm unaware of any Linux program that does the same.
17:23:28@thefrenchghosty:privacytools.ioTheFrenchGhostyI don't think wireshark can see problems coming from the hardware

I had an issue like this in the past with my Ethernet adapter dropping packets. When it happens you will see a bunch of retransmits in Wireshark or tcp connections try to reestablish or beacons disappear. I swapped the adapter with a pcie card and the issue went away.

I guess that's related, any idea guys?

17:31:09@thefrenchghosty:privacytools.ioTheFrenchGhostyI actually have a USB adapter available, I just want to know if the issue is software or hardware related before setting it up
17:33:14@megaarthur:privacytools.ioMegaArthurSounds hardware
17:33:19@megaarthur:privacytools.ioMegaArthurOr a faulty driver
17:33:27@megaarthur:privacytools.ioMegaArthur * Or a faulty driver
17:33:28@megaarthur:privacytools.ioMegaArthur~~Or a faulty router~~
17:33:41@thefrenchghosty:privacytools.ioTheFrenchGhostyNo problem on my desktop
17:34:41@thefrenchghosty:privacytools.ioTheFrenchGhostyI will try to reinstall/reset my VPN app and see if this still happen
17:34:44@megaarthur:privacytools.ioMegaArthur * ~~Or a faulty router~~
17:35:01@thefrenchghosty:privacytools.ioTheFrenchGhostyI don't think that's the case though

Do you have multiple aps?

I have a spare USB one, so that's really not a big deal

I ment multiple access point at your location. It looks like you got disconnected and when it grabbed the next available ap it failed to authenticate so it jumped back. I can't remember the name of the protocol but some Cisco aps can be setup to disconnect a user below a certain db threshold so they connect to a better ap. It works great unless the app you connect to is misconfigured.

Oh yeah, I suppose there are multiples since this is a connection for my whole building, but still it doesn't happen in other wireless devices (phone/tablet)

It could be you just don't notice it since they don't use the vpn. There is some extra time for your vpn to establish a connection I would bet. Have you tried some diagnostics from other devices?
18:03:54@thefrenchghosty:privacytools.ioTheFrenchGhostyNope since I don't have any issue

I would definitely say that's your problem then. The only way to know for sure is to check the wlan controller logs. If possible I would move to the other side of the building and test it.

Other than mounting the partition an inspecting the contents is there a quick way to uniquely identify similar drives? I've got 5 120gb ssds but I hate running through the list mounting them verytime when I'm using gparted.
