I Googled it and found out that it is another crap thingy that messes up with your connection. I went through all the debugging cycle once again without finding anything until I noticed that with MSI Dragon Center another utility was installed - cFosSpeed. It was all fine for a bit until I noticed that this time my connection drops to 7 Mb/s. It was stable and all was good until recently when I updated to the latest version of the Dragon Center.įirst thing I checked after updating is that the LAN Manager is disabled. I disabled it while being on 1 Mb/s and voila - I got back my 70 Mb/s straight away. Until I noticed a LAN Manager in the Dragon Center which was enabled by default. I spent countless hours trying to debug it, unplugging things one by one from all the sockets in my house, in the hope to find something that interferes with the powerline adapter but all to no avail. When connected to WIFI I could still see 70 Mb/s but because there are thick walls between the router and my PC the WIFI connection was never solid and I blamed the drop to 1 Mb/s on the old wiring of the house (remember, I use powerline adapter). My normal speed is 70 Mb/s but it used to drop to 1 Mb/s like a lot to the point where I was on that speed for 90% of the time. I, however, had constant issues with my connection.

I have Dragon Center installed from day one as I thought it has a nice feature to check for updates for BIOS and other bits (chipset, etc.). I built my PC about a year ago and the motherboard is MSI MPG Z390.

I live in an old house and my WIFI router on the ground floor so I use a powerline adaptor to get 'wired' internet connection on my main PC which is on the first floor.

I know this is not hardware related, but I just want to warn people here about my experience with it.
