Internet Connection Problems

Hey its me Catcher!

Anyone here have windows 7?
Anyone here have internet problems?
I Do :frowning:

I was hoping you could help.

The problem: Randomly my internet would cut me off.

Frequency: Random, every 4 hours

Temporary Solution: unplug gigabit switch and replug back in. I have to do this every time!

Permanent Solution : Needed

Facts:
Plugging computer directly into wall does not solve problem
Plugging computer into switch, then when it d/c i can turn off/on, to resolve issue
Reseting Router works
We tried two different routers both had same problems
I'm using Windows 7
I have 2 internet ports (we tried limiting to one, still failed)
It doesn't matter what I'm doing on the pc, it cuts off randomly
What appears: Yellow triangle on connection icon "cannot identify connection"
The Windows 7 problem solver cannot solve, instead tells me to unplug my gigabit switch...
I've tried 2 gigabit switches.
If it weren't for the switches i would've had to reset my router every time
I've tried ipcofig, flushdns, registerdns....
all other computers in my house work at the time of d/c
the connection does NOT comeback until i unplug/plug
All softwares are updated
My router is installed at latest version

Opinion:
It's not my router or switch, although my router log does report twinge attacks when i play games.
it's my computer
I'm not sure if its Windows 7, a program, something the needs the be refreshed like dns or cache, or hardware

Specs:
i7
6g Ram
32-bit
motherboard: Asus P6T deluxe V2
GPU: Nvidia 285 gtx
Norton Internet Security 2010
Marvell Yukon Driver Installed (Latest)

Thanks alot! All help is appreciated! [smiley=dankk2.gif]

Open a Command Shell (CMD.EXE)

Run "ipconfig /all" when everything is working

Run "ipconfig /all" when the internet connection stops working

Look for any differences

Dude have the same exact thing here except with a linksys router and it happens once a week or so. I found that it usually happens when I use a lot of bandwidth (DL especially - torrenting, streaming, gaming at the same time usually does the trick). Any solutions? I am planning to switch routers in an attempt to resolve the issue, but my current router works great on my other computers and I didn't have this issue back in the day with vista so I am very reluctant to say that just getting a new router will save me.

EDIT: Nice PC by the way ;D

I was able to get a screenshot today of ipconfig /all

I have the snapshot of when I first started the computer and it JUST had the yellow sign.

The snapshot of about 5 mins in.

The snapshot after I unplugged/plugged and the internet works.

All 3 of these are different.

picture 1
Does not even know the connection specific dns suffix,
The lease, ip4v address... does not appear.
All media states were disconnected

picture 2
Recognizes the dns comes from Comcast.
Has the lease, expiry, and address...
[Tunnel adapter isatap.hsd1.state.comcast.net] media state disconnected
[Tunnel adapter Local Area Connection*11] is left blank.

Picture 3
Looks exactly the same as picture 2
Exceptions of the time stamp
Ipv6 address for Tunnel adpater Local Area Connection*11 is slightly different. It starts out as fe80:: blah blah blah

I have a d-link router and switch.

Thanks for the help. ;D

Marvell Yukon Driver Installed

Sounds familiar. Similar problem with Windows 7 losing network connectivity on a works machine. We eventually came to the conclusion the Windows 7 driver for the said network card isn't all it should be.

Was there a magical fix to all this? :wink:

Thanks for pointing out the Marvell Yukon.. I searched and found a handful of people with these problems.

Turns out Windows 7 has a problem with Marvell.

Is this my problem?
Is there a magical fix?
I'll look into it tomorrow.

Jezuz, do you have any affiliation with Marvell Yukon drivers on your pc?

I'm still wondering why I made this thread on the Arduino website...
::slight_smile:

What happens if you unplug the ethernet cable from the computer, wait a few seconds, then plug it back in?

my magical fix was to install a totally different network card and the problem went away. There seems to be a problem with marvel.

More likely Windows 7 and Microsoft since the same NIC works flawlessly with XP. Cheap network card off ebay is probably the simplest solution, you can't go wrong with a decades old 8139....... :smiley:
