long story short, I am having abnormal disconnection + slow speed with [Intel I218-V] Ethernet adapter.
and I'm pretty sure there is problem with [Intel I218-V] based on reasons I stated bottom.
I've built my PC last year around this time, and my current build is
OS- Windows 10 64bit
CPU- [intel i7 5820k]
MoBo- [Asus sabertooth X99]
RAM - [32GB Gskill trident 3200]
GPU -[MSI RX480 4GB]
and I use [Netgear powerline] 1200 for my Ethernet connection
Now, here is problem I found out recently.
My MoBo [Asus sabertooth X99] has 2 Ethernet adapter which are [Intel® I218V] and [Realtek® 8111GR]
When I first built this PC, I do not remember how fast the internet speed was, but I believe [Intel® I218V] acted little faster than [Realtek® 8111GR],
So I only used [Intel® I218V] adapter.
Internet worked fine, but every day, around specific time (4-6 AM EST), I lost connection for about 5 min.
First, I thought it was problem with my ISP, because I heard they reset things sometime, but it happen too often and when I contacted my ISP, they said there seems no abnormal disconnections around my area. and ISP wasn't the problem because of my second concern.
Second, I was expecting that my old router causing the random disconnection, but then, whenever this disconnection happens in my PC, Wi-Fi from my smartphone which was connected to same router worked just fine.
Third, I thought it was problem with Powerline from Netgear. but for this, I have no idea to figure out what and where the problem would be.
could be device failure, or my house resets power once a while, I really don't know.
I mean, it was disconnected only for like 5 min-ish, yet it bothers the hell out of me since it almost happen everyday.
and not only around 4-6 AM, random disconnection happened as well.
It happened yesterday as well around same time (4-6AM). my WiFi was still working, and I got little sick of it, so I took out my Ethernet cable from [Intel® I218V] and connected to [Realtek® 8111GR].
Internet worked right away which was fine.
but I felt somethings little different, then I noticed things loads quicker than before in internet browser.
I reconnected my Ethernet cable into [Intel® I218V].
internet worked fine, so I ran internet speed test.
Down : 10mbps (highest 20mbps maybe)
Up : under 5mbps
when I first built this PC, I remember that it was way higher (40-50mbps)
because I was happy with improvement from my super old PC which was only getting 20mbps.
I pulled cabled again and connected it into [Realtek® 8111GR] then ran the speed test
it got 50mbps download and it was stable.
I do not know what happened and what changed things past 1 year.
anyone having similar problem? know any solution to bring [Intel® I218V] back?
I've tried some different thing from my research, mostly simple/easy modifications.
like changing power saving option.
delete/reinstalling latest driver.
and seems like it didn't do anything to it.
My question is can these Ethernet adapters wear-off? or get damaged from power via Ethernet cable?
+in addition, even though down speed from test was 10mbps for [Intel® I218V] and 50mbps for [Realtek® 8111GR].
when I try download actual things via applications or internet browser,(for example, 10-20GB sized games from Steam) both adapter got pretty much similar download speed (6.8MB/s max).
but still, picture, video from youtube, and websites load much much faster with [Realtek® 8111GR].
+in Advance option what kind of setting might help?
