Hi,
 
I hope someone can help me, I've been having this issue ever since building this computer in November 2011  (hard to believe it's been that long!).  Every time I reset or turn off and back on my computer I lose my internet connection.  Took forever figuring out it wasn't my router or my cable modem because at first I would reset them and sometimes the internet connection would come back on, sometimes it wouldn't.  I just kept resetting them until it worked.
 
So early on I tried disabling one of my Dual LAN ports on a suggestion from a techie friend... but that didn't help.  Usually I just leave my computer running 24/7 so it isn't a problem.
 
Anyhow something seemed to happen recently in that resetting my router/modem didn't seem to help.  Messing around with it further I noticed that my spare computer wasn't losing its internet so I realized it must be my computer after all.
 
SO, now I've found that all I need to do is (to have both LAN ports enabled and) just swap the cable from my router to my other LAN port! It's easier than resetting my modem and router, but it's back and forth with the cable on each reset.  back and forth, back and forth...  seems to work every time without fail this way.
 
I've even tried using both LAN ports LOL  this didn't really work either
 
All my drivers are up to date, windows update, firmware, everything I can think of is current.
 
I have a Linksys WRT120N, an older but reliable router.  Also have tried a newer model Kingston Router (can provide a model number if needed but it's packed away and I doubt it's my router at this point).
 
Sorry for being verbose, just trying to be thorough and provide all the necessary info the first time.
 
Thanks!

In the BIOS are the lan ports set to enabled instead of auto?

Set the LAN ports to enabled and see if it helps

Thanks,  I will do and report back.

If I overclock to high I loose my internet. I see you have an overclock. try your default clock

 
Thanks for the suggestion, I'll keep it in mind.  I don't think that's the case for me tho, I've had this problem for some time before my current cpu or my overclocking.  Additionally, my OC is pretty tame for what's possible with my chip :)  I appreciate the help tho!

ok, well I've tried BIOS setting my LAN ports to AUTO and ENABLED both now....  same thing unfortunately.

Hopefully you figure it out, and are able to browse the internet again without interruption from the "Orbital Explorer" to "Ellis Island".          

:D  thanks!  I hope so too.
 
Firmware is up to date on the router.  I'm not thinking it's the router, but not positive of course.  I have two computers on my network.  What originally clued me into changing LAN ports was the fact my second computer never loses connection.  This is what I feel dumb about, cause I've had the issue for the last couple of years and each time I lose it on my main computer I never thought to go check the other,  I was just assuming it was my router or my cable modem.  I'd reset them and sometimes reestablish connection, sometimes not tho.
 
This is why I ended up here, the manufacturer of my motherboard, thinking, hoping, that someone had a similar issue with dual LAN ports.
 
The only time I lose my connection is when resetting my computer.
 
Before discovering swapping my LAN ports would instantly restore my computers connection I was thinking it MUST be the router, I even have a newer Kingston router that I've tried, but still has the same issue.
 
And, again, unfortunately... I've tried lowering the MTU too.

thanks Bob, using the Find and Fix Internet Connections just results in a "Troubleshooting couldn't identify the problem" message.
 
and I'm not finding anything on the MS FixIt site  (sigh)
 
thank you tho, I really appreciate your help

yeah... same here, no linksys software installed, windows is managing.
 
*sadness*
 
I have a feeling I'm going to be stuck with this for the lifetime of this computer...
 
thanks to everyone for trying to help!

Not necessarily true..Those ports can and do act up/go bad..Just go buy a , wired or wireless, for 10 to 20 bones or so..You'll be happy again

unfortunately all my slots/space is completely filled lol

yeah... well... this is true,  EVERYTHING is taken up. no space whatsoever for anything. my two radeons and my audio card are pretty selfish.
 
can you believe... I've actually filled every single USB port as well including the front/top panel and the two extension usb ports on my g-19 keyboard.  I guess I could maybe look for an expansion Hub tho.  my computer is kinda nuts... I keep adding to it...  I LOVE it, it's a lot of fun... but it's about maxed out.

you know, I don't remember getting the usb bracket with this motherboard...  hmmm...  probly did and just didn't use it, but yeah, all space is gone now anyhow.  my last slot was filled with a lighting kit controller lol  I'm kinda weird about 'it has to look good'  so a hub then would be the way to go.
 
I have a question tho, what IS the purpose of having two LAN ports anyhow?  I guess it has something to do with being able to be on two networks... but why would you want that? 
 
When I plugged in both LANs to the same router it just caused issues, but I wonder if I could somehow make that work... this probly sounds stupid but I can't help think it when all I need to do to restore my internet is just swap my routers connection from one LAN port to the other.

Thanks Jedi, I had the newest until the 24th of last month.... didn't expect there to be a new version as the last were pretty recent too.  either way I got the new ones but no love for me yeah, got them from realtek too.
 
also went on to try disabling one port in the bios (instead of just device manager), that didn't help either.
 
I've tried different cables, yes.

So, I like to tinker and get the most from my computer.  I'm pretty ok with tech and figuring things out, I built my last two computers... done a bit of overclocking too.  I've searched and read a bit about dual LANs, but I'm not getting it really...  could someone dumb it down for me?  two LAN ports is a benefit right?  since I'm not solving this problem directly maybe I can solve it indirectly-by using both ports.  I have two computers on my network. and I have two routers (one unused and in the box).  Is there something cool I can do with what I have? what benefits might there be?
 
Thanks you guys! :)
