Weird Network Issue.. Fix needed
October 29th, 2013
We have two laptops, let’s call it A and B. When the LAN cable is connected to A, there are frequent disconnects/timeout. Basically a loss of internet connection. I determine this using a ping x.x.x.x -t.
However, using laptop B, the connection is fine. How can I say it’s fine? Because when it’s not working on A, I switch the LAN cable to B and it can connect properly. So I’ve verified that there is something wrong with A.
Both are Win7 32 bits laptops.
My guess is, there is a defect either hardware/software relating to network adapter/driver/card.
A and B has updated network drivers.
A uses RealTek, I am pretty sure that’s a very common network card.
The main question is, how to fix this?
Of course, that involves more specific steps like how to identify the real problem? How to troubleshoot that problem?
I want to fix laptop A. It’s my first laptop, and it’s not that old, prolly 2 years.
Thanks.
EDIT:
Few more info..
I can use it okay for sometime, but it will DC from time to time, sometimes short periods (1-2 mins), sometimes quite long (5-10 mins).
This also a weird things that I noticed, I play a lot of Heroes of Newerth (an online game if you will), and usually after every game, I get a short DC. It doesnt happen during the game, but right after the game! I am pretty sure that is a symptom. Same with using uTorrent.
network cards rarely broke… could be the LAN port in your laptop (or modem). If the cable is not firmly connect (or the port is broken) with a litle touch in your laptop the cabe could lose connection for a few moments. try to solid connect the cable and then run ping -t for some time and see if the connection drops. If not, with the ping -t still running try touch the cable to see if it drop.
tell us what happen
it is firmly connected, because you hear the CLICK when it is in. and if i try to pull it out, I can’t.
Yes, I have ran ping -t for 2 weeks now.. I thought initially it was an ISP issue, but after testing it consistently between laptops A and B… I was convinced there was something wrong with A.
Can you try running a ping -t to the IP of your modem? This will establish whether it is an issue internal to your system or external (I would assume it is internal but it never hurts to check).
The issue may be caused by your modem configuration so try resetting it to factory configuration (call your ISP if you are unsure of how to do this/unsure of how to reconfigure your DSL authentication details) and see if that has any affect on the problem.
If resetting the modem doesn’t help, then I’d have to assume it is a problem with the network card or IP stack on the computer. Perhaps if you try uninstalling the drivers for the card and reinstalling them (try default Windows ones and ones from the RealTek website) to see if that helps.
some help? shameless bump
I don’t know how to fix issue but I know how you can fix your problem. You can connect it to the B and share the connection with A, this is less efficient solution and your connection will probably be slower than your maximum, but you’d have Internet access on both laptops.

actually, I am doing that right now… using Connectify.
Since it’s wireless, it might be a port connection issue.. hmmm. anyways. tnx.
