Hi! So, I'm experiencing random Internet disconnections that last for a few seconds before reconnecting by itself. Some infos: -Connected via ethernet cable. -I'm on Win10 LTSC (1809). -The motherboard is an Asus M51AC (Asus H87M-PRO with a slighty locked down BIOS). -The LAN card is a Realtek. What happens exactly? Internet disconnects itself from the PC for a few seconds and then reconnects itself. While it happens the other connected devices are fine (both via cable and Wifi). When it happens? Completely random, I've noticed it more frequently while playing video games (especially Dead By Daylight and League of Legends), but that could mean nothing since I can notice it more easily from there when I get kicked out of a game session. Infact iirc it happened one time while I was browsing youtube. I can go for hours (literally 6/10hrs or more) without having issues and it randomly happens. Once a day at least tho, and usually when I play a game. What have you tried? -Different Modem. -Different cable and ethernet port. -Different ISP (I was having the same issue before changing it). -Tweaking the LAN options (disable battery saving, green ethernet and similar). -Updating/changing drivers. -Removing any other Wifi PCIe CARD that may conflict. -Checking the windows event report to check if anything wrong.-->I didn't noticed anything strange, but I'm not an expert about the application, so I may missed something, I'm not 100% sure. What haven't you tried yet? -Formatting and installing a different windows version. -Using a live Linux.-->Since I don't know the cause, I could stare at the desktop for days without anything happening and while having the issue anyway. For how long have you had the issue? A year or so, not sure, a long time anyway. Before buying a new motherboard or a new LAN card, I want to make sure that is actually an hardware issue. What do you guys reccomend me to do before I format everything? Did I miss something? If you need more infos, just ask. Thanks.
it sounds like some electrical connection could be faulty.... maybe a wire hanging on just by a single copper strand. you already replaced the ethernet stuff, so that could not be it. rising temps could do nasty things too..does the pc get much warmerwhen you are gaming? i would not format everything; that is very drastic, and carries no guarantee to solve the issue. can you try some wifi dongle to connect? they are cheap enough, i would try that first..
I can't try it. First it's hard to move a desktop PC. Secondly I can't leave the PC to a friend's house waiting for the issue to appear, since it can take days.
See if u have the same issue connected via wifi if it does could be a issue with OS and drivers have u check your device manager and see if their any conflicts their HW or driver related, I think I saw a thread here were people were reporting a similar issue running Win10 LTSC (1809)
that sounds to me like connection intermittent issue could be driver related...try the wifi for a bit and see if the connection drops or install another lan card but i dont think is a HW issue.
Ok guys, thanks for the suggestions. I'll try with wifi and see if it changes anything and I'll report back. My last resort before an hardware change is formatting and installing a different windows version.
Hi! If I were you I'll try these: 1- Purchase a gigabit PCI or PCIe NIC (ethernet card) and install it. Cost would be under $10. 2- Hook your ethernet cable to the new card and monitor it. If still disconnects, then either mobo, ethernet wire, router or modem. Regardless this fixes the issue or not, having a 2nd NIC on hand would not hurt. Good luck!
I'll purchase a new NIC after I tried every software possible cause. But yea, you're right a 2nd NIC is always useful anyway.
If the connection disconnects, it should show on any live distro or a windows live/winpe cd/dvd, too, shouldn't it (showing if connected or not)? Easiest way to check if it's OS related or hardware.
Boot your pc into safe mode with networking. If it disconnects then look for a hardware issue, if not then look for a software issue
If the problem usually sussist when I'm playing a game, or at least it's where I notice it the most, and since It can go for hours without it happening, how I can I check the issue through a live distro? I can't run a game and hope the problem sussist into the live too.
EDIT. It seems that it disconnects also when I'm connected via WiFi with a different NIC. So it may actually be a software issue.
Dr4w from what you've said the problem is in the OS. Do you happen to have another Hard Drive that you can install your OS onto. This would prove one way or the other whats wrong. I've seen this happen many times and 85% of the time it's the OS. Very rare for the modem chip to randomly disconnect . I believe you said you've had this OS installed for a long time, I bet that you have picked up a few glitches along the way. Good Luck let us know what you found.
UPDATE. I formatted and installed another Windows 10 version (Enterprise 1909 NON LTS). The issue persist. Do you guys think it's an hardware issue at this point?
