I'm having a strange issue with my network connection.  I have a Linksys WTN310GB Wireless Router.  I have my laptop connected wirelessly as well as my playstation.  No problems at all.  I also have an older pc with an Asus P4P800D motherboard with a built in GB Lan wired connection.

 

As soon as I plug the PC into my router, I lose all my wireless connections and cannot get a connection. As soon as I disconnect the pc, I can repair the wireless connection and all is well.  However I can't repair the connection when my PC is plugged in.  If I connect my laptop via a wired connection it works fine.  I can't figure out why my pc knocks out my wireless connection. 

 

DOes anyone have any ideas?

Are your wireless and your wired networks on separate subnets?  Or is the router bridging them to the same subnet?

 

Does your old wired PC use a static IP by any chance?

 

If you give some details about how you configured your network(s), we may think of something.

 

Oh boy, I'm not that technical. When I look at cisco Network Magic mapping, it shows they both have the same subnet.  But I don't know how to tell if the router is bridging them.  The pc is not using a static ip address.

 

I have my router set to mixed, wpa2 personel

 

The other thing I noticed is that if I plug in my laptop to the router, I don't lose the wireless connection.  If I unplug my laptop from the router, I then lose my wireless connection.

The other thing I noticed is that if I plug in my laptop to the router, I don't lose the wireless connection.

At that particular time, type  ipconfig /all  in a dos box.  Paste the output here.

Also, what does ipconfig show on the old PC?

 

I'm wondering if it could be a another cable I have plugged into the router...Right now I unplugged everything and just have the Unraid Server plugged into the router and my pc.  Nothing else.  I don't seem to be dropping my wireless connection.  I had another cable plugged into the router for my laptop when I want to watch a movie on my tv via HDMI.  Instead of connecting wirelessly I plug it in.  It's the ony way I can get smooth playback for blu ray movies on my unraid server.  I had one end plugged in and the other end sitting loose. The cable says CAT 5

 

 

The cable says CAT 5

For a gigabit connection the cable has to be CAT5e (CAT5+) or CAT6.

A CAT5 cable will make your NICs negotiate a 100MBit/s connection, but it won't kill your network like you described.

 

I think I have another cable somewhere around.  I'll give it a try and see what happens.  FOr the last hour I haven't lost my wireless connection at all.  I'm afraid to plug the other cable in to test now.  I'll call it a night for now and try tomorrow morning.

 

Thanks for the help!

? I've never seen or heard of this before.. CAT5 cable just isnt rated for GB speeds, but shouldnt make it negotiate at 100MB/s. The equipment can't sense what rating the cable has, as long as it is wired properly..

It happened to me.  I was using an older cable and was getting only Fast ethernet.  Change the cable and went to GB speed.

I stand corrected...

Older cables often had only two of the four pairs connected.  Some did not have the pairs twisted to provide self-shielding.  Also, many older cables were wired for telephone use.  The "pairs" are connected differently, and the pairing is incorrect for LAN use.

DigitalDivide said he's using CAT5.  That's not that old.  It is a LAN cable, and the pins are connected the same way as the gigabit cable, only it's not shielded properly for gigabit speeds.  So the NICs will first try gigabit connection and fail, and then they'll try 100MBit and succeed.

 

Mine said cat5.  I replaced it with cat5e.

Right.  That's what's needed to go to gigabit speed if the NICs support gigabit.

 

Well bought I Cat 6 cable today and everything is working 100%.  I have my unraid server plugged in, my old pc, and the new cable plugged into the router but not plugged in on the other end.  My laptop isn't dropping its wireless connection. 

 

I almost had a heart attack.  I tried playing a blu ray movie via my unraid server on my laptop via hdmi to my receiver and tv.  First off I wasn't getting 5.1 and the video was really choppy.  I couldn't figure out what happened since my 5.1 was definitely working about 2 weeks ago.  No matter what I did I couldn't get my HDMI connection to see 5.1 speakers.  I then remembered that I upgraded from ATI Catalyst 10.3 beta to the final 10.3 about 2 weeks ago.  Reinstalled the 10.3 and BANG 5.1 is back and smooth playback of my blu ray.

 

Life is good again lol

 

Thanks for all the help everyone!
