    Problems with [Intel I218-V] Ethernet adapter

    tain

      Hi!

       

      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.

      result was

      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?
