Integrated network card with GigE switch

Recently my company switched to a GigE backbone, with GigE switches. About a week and a half later, we started having problems with our Gateway E-4100s. Acts like the network card is inop. Will try to connect, then drop the network connection.

I tried updating the drivers, setting the speed of the card, and trying to go with 1000Mps. Sometimes it would work, then I would restart, and the system would not see the Nic any longer. Please let me know if anyone has any ideas. Thanks.

Our fix for now is to put in a PCI 10/100 network card.

    I checked, the switch is set to auto-negotiate. They are Nortel 5520 switches. As far as I know, the few 10/100 NICs that we put in are not having any problems.

    This is like the bulging capacitor on the motherboards insident all over again!!! :)

Hi twalden,

I'm not sure what brand of switches your company has moved to, but it sounds like perhaps the switches are mandating a gigabit (1000Mbps) connection rather than an auto-negotiated one. If you know how to patch or remote in to the switches, check those settings; if you don't, reply with the make and model of the switches and I can get you further info.

I realize this sounds funky but I've had a very similar experience with some Cisco switches in the past. Does the 10/100 NIC you put in maintain the connection, or does it drop from time to time as well?

In compac presario v3000 laptop sound is not working shows no sound card but all icons of sound in device manager are ok like audio codec,legacy,etc. now what is the problem?

Hello, I've a Compaq NC6000 laptop, and that doesn't show a soundcard either, aswell as the Audio Codecs and Legacy Audio Drivers, it shows a 'SoundMAX Integrated Digital Audio'. There's an audio mute switch on the front panel, next to the vol up/down switches on mine. Have you taken a look at the hp support pages for your laptop? If not, try and answer the country question. Has it ever worked? If you've recently reinstalled the OS maybe you need to install the chipset drivers, etc....they're also available to download from the support website. Regards, nicam49

Can you please give me a diagram on how the internet works?

hi, Well in case of diagrams I ll use some images. Internet is a network which comprises a massive amount of Public networks, Inter/Intra/Extra networks, servers-hosts, routers, backbones, cables, satellites with billions of users.
This diagram shows how an internal network is formed.
This diagram shows how the users and their computers, companies and organization connect to Internet via ISP backbone. As an example using DSL or Cable Modems.
This is how a Server serves its users. I assume you know the functionality of Servers, Routers. Diagram
How a Web server works? Diagram

My 3com 4200 28 ports is restarting by itself many

Base from the description of your problem its only showing that some of the port on of your Ethernet switch is already getting bad and this usually happen on switch like this and eventually all port will go bad and will lead to the replacement of the device. With this type of problem you can first try to adjust the speed of your network card to 10 half duplex and check if that will correct the connectivity problem and if it does its just a sign that sooner or later the device is already getting bad and since its only a switch there's no firmware that we can load to it or even a reset button to bring the device back to its default settings.

Unexplained network problems.

I would be glad to help with this.
How many VLANs do you have? How many users per VLAN? Do you have a generic diagram (stripped of all company info) that you can share? Can you send me a "sh tech" from the core switch so I have a better feel for how things are configured?

Consistent 2 minute dropout

Have you tried to telnet into your device and turn up the logging? Also, have you confirmed at what duplex you are running on the ports that the actual connection is coming in on? Is there a firewall connected to your switches? If so, have you checked the NIC cards to make sure they are functioning appropiately? Check out your DMZ card to see if that is causing any issues.

Wireless network.

Hello Linxz

(01) In both cases, are you referring to the same network adapter on the same computer?

(02) Or did you lose network connectivity w/ one adapter initially then switch to using a different adapter (same computer) and now it has failed as well?

(03) If the answer is YES to question (01) (and NO to question (02)), then, it does sound as though your integrated NIC (network adapter) has failed. Since it was an intermittent problem initially and then became a "hard" (continuous) problem, I'm more inclined to believe it is a hardware rather than a software (drivers) issue.

(04) Are you experiencing ANY other issues at all on this computer?

(05) My recommendation is to install a new NIC since it would be impossible or expensive to repair or to replace the integrated NIC.

Please, post back here w/ your answers, observations, what you've tried and the results along w/ any more questions or comments you may have. We are here to help.

Thank you,
BJ @:)

Won't allow connection to router

Since each of these devices is rated for 1000Mb/s, everything should be compatible. Make sure the NIC driver is up-to-date on your computer....and use automatic settings for speed and duplex wherever you have the option of setting it. The only other thing I can think of is to try a "crossover" cable between the router and switch...although this function is usually handled automatically in most modern interfaces.
