randomly losing connection to ONLY steam

[You say this is suicide]

I have an issue where I randomly lose connection to only steam, everything else is fine, but I can't reconnect to steam until I restart steam.
I've tried
Reinstalling steam
adding firewall exceptions and turning off firewall
putting my PC in a DMZ on my router
using wired and wireless connections
turning flow control off
and quite a few others that I can't remember and I still get this issue. Any ideas?

Boot the computer into safe mode with networking. Stay connected with an ethernet cable from the modem to the computer and totally bypass all wireless hardware and connections.

Then, launch Steam in safe mode with networking. It must be "with networking" enabled.

You can post here while in safe mode with networking, or should be able to that is.

Post the Windows you have and if it is 32 or 64 bit.

Post the computer model number and model exactly. If it is custom built, post the motherboard instead.

64 bit windows.

To be more clear, I lose connection to steam friends and downloads, which causes me to get kicked from Arma 3 that requires steam authentication, I can still browse the store front.

Thanks but this above does not fully answer this.

No matter how I type it and word the question, people seem to never post what Windows they have as well as if it is 32 or 64 bit.

Always post your OS like this....

For example, Windows 7 64 bit, Windows 8.1 32 bit. Those are examples on how to post your complete OS for Windows.

And none of your replies state if you did this or not yet, please.......

My apologies, I've just booted into safe mode with networking and my OS is Windows 10 Pro 64 bit

No, please excuse me if that seemed rude of me, about the OS. Thanks.

So you have tested Steam in safe mode with networking now ? You cannot play games in this boot, but you can browse the store and try to download games for a while to see what happens.

Be sure you are hooked up using an ethernet cable also, directly from the computer to the modem. Bypass any router or wireless hardware/connections for now.

Are there any other devices consuming bandwidth in your home network now ? If there are, that can be suspect to your problem.

This is a home network, right ?

EDIT...

I see a high suspect to your problems, if you have it installed.

That board has a Killer Network device, and I bet you have the Killer Network Access Manager installed, perhaps.

This is the board, correct ?

See how under the LAN driver there, it shows a download for the Killer driver ONLY ?

That is what you need. If you have the Killer Network Access Manager software installed, fully uninstall that. It has been seen to conflict with Steam connectivity in the past.

Don't forget to restart your computer after you uninstall any software. Also, while you are on that MSI manufacturer's website I linked, make sure all of your device drivers are fully up to date, each and every one of them, along with the Killer Driver and not the Manager software.

Tried everything for two weeks. Last thing tried was to camouflage the ISP by using a VPN to connect to the servers and it never disconnected after that so it was the internet service provider the whole time blocking arma for some reason. Hope this helps someone.
