Question about Dell Precision M90 Notebook

1 Answer

I am a Support Tech for the Army and really can't find a solution to this problem. When I plug in my Cat5 cable it still says network unplugged only on my M90 computers, all other Dells I have connect find but this one, its happened on two of my M90's already. Has anyone ever seen this? My network is down right now but it should at least still connect to the switch right?

Perhaps the "other" Dell's network cards have auto-sense, and you're using a crossover cable... when you shove it into the M90, you get nothing because the wiring of the Patch Cable is not right.

Try a known good "straight through" patch cable.

    How far away are you (cable-wise) from the switch (or hub)?

    Take a known good patch cable, walk to the network closet where the switch is and plug the M90 into a known good port. Does it now work? Great! Problem is either impedence in the wiring betwixt the switch and network jack and/or distance from switch.

    Still doesn't work? Wierd? Perhaps the network adaptors are disabled in the control panel or you've got a rare case in which both the network adapters in two different laptops are bad. Make sure they are enabled, of course, both in the BIOS and in the control panel/network dialog. Still no love? Plug the M90 into a different make/model of hub switch and see if it works...

Crossover cable asus eeepc

I would think you can do that through a network router or you can make a crossover cat5 cable by switching wires 1 & 2, and 3 & 6 of the plug on one end.

Cat5 network cable can be crossed by switching wires 1+2 and 3+6 on one end. You have to replace the plug in order to do that unless you open the shield of the wire exposing it to tie them manually together.

Acer aspire 5335 connects to wireless internet, but not with eathernet cat5 cable?? thanks

Make sure the Network Connection for the LAN is not disabled. Click Start/Control Panel and look for the Network Connections. Make sure the Network Connection for the LAN is not disabled. if it is disabled, right click on it and select enable.

Also the port could be bad on the computer. If it does not light up when you put the cable in the port might be damaged.

Will let me get in to the internet with out the wireless network.

Your laptop should have an ethernet port on your laptop. If you can plug your laptop with a Cat5 network cable and plug that cable into your internet source you should be able to connect to the internet.

Your internet source could be your modem or router. If you have dial-up, you would have to check to see if your netbook has a dial-up modem built into it.

If you do not have these available and no wireless available, you will be unable to connect to the internet.

Dell E6400 onboard NIC cannot get network connection - "A Cable Is Unplugged". The laptop is undocked with CAT5 cable firmly attached.

I'd suggest updating the NIC driver in Device Manager. But, the message "A Cable is Unplugged" tells me that the NIC port, the CAT5, or the port where is is connected to your modem/router may be faulty. Try moving the cable to a different port on your modem/router, first. Then, try another CAT5. If still a problem, the NIC port is probably faulty. Hope this helps.

Belkin N router reads everything but the computer.

If your router was working before, and suddenly stopped working, then you probably need to reset it.
Unplug the router from power, also unplug all network cables from it.
Wait about 30 seconds.
Plug power back in, followed by network cables.
Wait some more seconds while the router restarts.
Only the Power light and the Status light should be solid.
All others in use must be blinking, which means they are in use.

Try connecting to the internet with cable first, then try wireless.

It should work.

I have a network and wireless issue needs to be fixed

First thing to do is make sure they are all in the same workgroup and that all three have identical user accounts and passwords.

Once you've done that, make sure all of them have sharing enabled for the areas you want to share of each drive.

This should do it. Let us know if you need further assistance.

How can I connect my toshiba tecra 8100 to my pc?

There are a few ways to do this, and the choice is yours.

Visit this site:

It will explain the different methods and what is required for each.

The best option would be to use a Ethernet Cross-Over cable.

Then enable File and Printer Sharing, which can be found in My Network Places.

The site should direct you.

Let us know if you run into any bumps.
Good luck

Will not connect to the internet wired or wireless

Unplug your power from the modem first and after that unplug your power to your router, disconnect all your cat5 cables and wait for at least 20 secs. After 20 secs or so go ahead and plug your power back to your modem and wait until all the flashing green lights are solid and that the link light starts blinking. After that plug in your Routers power (You can also reboot your PC while this is going on) . Wait until all blinking lights becomes steady then re-connect your cat5 from the modem to your routers uplink and last the cat5 cable from the router to your PC. If you'd rather not test the direct connection then go ahead and switch your wireless on.

Your wireless connection properties on your PC under "Internet Protocol TCP/IP" should be set to "Obtain IP address automatically" and that "Obtain DNS server address automatically" should also be set. Your routers should, if not already, be set to automatic DHCP. Make sure that on your Device Manager > Network Adapters that your wireless network adapter is not disabled and that it has the correct driver (yellow exclamation on it indicates it needs correct driver). You should disable your integrated ethernet LAN card if you have enabled your wireless Network Adapter to avoid conflict.

On your Wireless Network Connection properties under "Wireless Network" tab go to "Preferred networks" and highlight your wireless network name (SSID) . After highlighting click on the "Advanced" button and select "Access Point (infrastructure only) networks only"
