Question about PC Desktops

1 Answer

I cannot connect to the Internet via a wireless connection on a laptop, and am only able to ping in safe mode. A Time-Warner expert believes that it is a virus or Trojan, but I have been able to connect at another location. Weird. Any suggestions would be appreciated.

    KI am running Windows XP Home. I have three computers, two notebooks and a desktop. One of the notebooks and the desktop connect perfectly well. The problem only affects one notebook. No, none of the internet options has been changed. Yes, I get a proper IP address, but the system will only ping in safe mode.



    I will try the programmes suggested to check for virus/spyware/malware.



    Thank you.

    But if I cannot connect to the Internet -- the problem with this computer --- I cannot download any virus/malware/spyware programmes!! I have Norton 360, and it indicates no problems.

  • Operadiva Oct 20, 2008

    My apologies for my incivility. I was called away suddenly, and this problem was shoved down the priority list.



    Thank you all for your help. This is a fabulous resource, and I am most grateful for your willingness to come to my aid.



    Time-Warner (reluctantly) discovered that their router and/or modem were at fault, and replaced them both with one nifty new unit. All is now well.

    Has this always been a problem on this laptop, or did it just begin recently?

    How familiar are you with windows troubleshooting?

    Have you ever, or do you know how to modify the registry?

    This way I'll be able to guide you appropriately.

    I would suggest that you first start by obtaining some utilities from the internet. (use your other computers and put them on a flash drive or cd)

    Go to www.sysinternals.com (now a Microsoft website) This third party company made some really nice utilities that Microsoft ended up buying them out for. Specifically, you want to download ProcessExplorer (A really great process viewer) and AutoRuns (a really great system configuration utility) Both of these can work together to help troubleshoot problems, but you need to have a little experience. If you don't, we can start by at least using AutoRuns and what you would want to do is go through the list it gives you and write down everything that does not say Microsoft in the publisher/author field. Specifically we are looking for processes and programs that either are made by companies we know make spyware/adware, or better yet, publisher fields that are left completely blank. Most virus developers will not go through the trouble to fill those fields out. Be carefull not to delete any entries in that list, nor do you want to uncheck any without first determining whether or not they really are issues.

    If you are familiar with processes, you can open ProcessExplorer first, then AutoRuns. If you find something suspicious in AutoRuns, you can right click on the item, and then click on either properties or info and it will ask ProcessExplorer to determine whether or not the program is currently running. If it is, that process will be shown to you for further investigation. You also might want to check the 'Winlogon' and 'explorer' processes and see what threads are running underneth them. Do this by right clicking on the process from inside ProcessExplorer and clicking properties. Then click on the 'Threads' tab to see all threads running inside that process. Many times, hackers try to hide processes by buring them under parent processes. Right click on each thread and check it's properties. Take note of which ones are not Microsoft programs and especially those that have no identifing information.

    I'll wait for further info before we go any further.

    Also, a really nice utiliy, if you can get a hold of it, is 'Hirens boot CD.' You need to know how to download it and burn the image on CD. This cd has some nifty utilities that you can use to try to restore any settings that may have been damaged by malware.

    When you say 'via a wireless connection,' does this mean that this problem is only limited to the wireless connection? Can you access the internet via a direct cable connection?

    I also need some more info on:

    What OS are you running? Windows XP (home/pro), 2000, Vista, OS X, Linux

    What browser are you testing with?

    Are you connecting directly to the ISP provided equipment, or do you have your own in between?

Post more details

in the mean time try this:

1. if it's a virus or malware clean up your computer (use AVG or avast for virus clean up and Spybot S&D, adware se, and a-squared for other malware.. all of them are free). make sure you update the programs and run them 1 or 2 times depending how contaminated your system is.

2. repair your internet adapter's connection:. in network connections, select right click your network adapter and select repair.. see if you get an valid ip address different from 0.0.0.0

3. Do you have access to your access point / router on the network you have problems with.
you need to have the SSID for your Access point (router) and a key or passphrase (if setup) if you don't have those check with your network administrator

4. did you mess around with the internet options?.. open your browser go into tools, internet options, security tab and reset your internet settings for the internet zone to default.

5. check you are within range and that your wireless adapter is on.

good luck and post more details to be assisted further if needed.

    goraventech, testing suggestion is excellent..



    I just wanted to suggest the following



    if the wireless adapter is a pci card test that on the other laptop if possible to rule out the possibility of hardware malfunctioning.



    when you are saying you can ping in safe mode.. what are you pinging? is another computer in your network or is it another computer/server outside your network?... if it's outside your network it resolving ip into name addresses?



    if it is another computer in your network your wireless adapter may be ok.. so check

    a. your access point configuration

    b.your firewall settings on your system and one your router

    c. your antivirus configuration for internet settings.



    is the other laptop using norton 360 as well?



    has it ever work before? if yes try to remember any new installations and use system restore or manually uninstalled to go back to previous configuration.

    that was weird... If the router or the modem were at fault what you would expect is for no internet connection to be avaliable anywhere.. unless is specifically the router.. and the plugged where your computer problem was connected to, or if the computer was connected to the access point wireless probably the antennae on the access point/router was the problem (that if the other 2 computers were wire connected)



    just for feedback sake.. could you note what type of setup you had?? were all the computer wired plugged into the router?, you had a modem/router? or router and modem...?



    also.. that's why the more specifics you give the better the chances to get a more solid solution otherwise we are all just gessing!! and shooting in the dark.

I have a dell optiplex gx520,it is hooked up to wireless connection and it's showing that the signal is good,but IE won't let us view webpage......


can you check if have a valild IP address?

1. Start > RUN > type in "cmd"
2. On the command prompt windows (black DOS window),
> type "ipconfig" > hit Enter
> you should have a valid IP address (something like 192.168.x.x)
• if yes, then try to ping a website
• if no, (you should see somthing like 169.254.x.x), check your wireless settings again.
**good signal doesnt mean that you are connected, it could be a conflict with wireless encryptions too..**
3. to perform PING
> on the CMD screen (back DOS based window), type "ping (space) google.com"
> you should see ping statistics, something like "packets sent=4 received=4 lost=0"
• if 0% lost > your connected to the internet
• if 100% lost > you have no connection
> again check your wireless again
4. If you can Ping and you can't still view webpages using IE here's what I suggest
• Optimize your browser
-delete temporary internet files and cookies
4a.1 Open Internet Explorer
4a.2 Click "Tools" (the icon that looks ike a cogwheel / gear; usually at the upper right corner of internet explorer)
4a.3 Click "Internet Options"
4a.3 Click "Delete" under the General Tab Screen
4a.4 Restart Internet Explorer
• Reset Internet Explorer to factory settings
4b.1 Open Internet Explorer
4b.2 Click "Tools" (the icon that looks ike a cogwheel / gear; usually at the upper right corner of internet explorer)
4b.3 Click "Internet Options"
4b.4 Click on the "Advanced" tab
4b.5 Click on "RESET"

Cable and wireless question


Not possible, since the "input" to the 2WIRE modem is a 4-wire telephone-line, not an 8-wire Ethernet cable.

Instead, spend about $40 to buy a D-Link Wireless G modem, and connect its WAN port to the cable-modem, and connect up to 4 Ethernet cables to "wired" computers, and configure the "wireless" component of the D-Link router.

Adding Dell Dimension 4600 to existing wireless network?...


Go to Staples and purchase a Linksys USB wireless-G (only G needed - the new "N" protocol is overkill) adapter (~$60.00). Insert the Linksys CD and follow the instructions. When prompted, plug the USB adapter into the Dell (frt or back) doesn't matter. If his "roomies" have security enabled on their router, you'll need to know the level, password/passphrase, and the network name that they assigned.
Good luck.

I got a cyberpower pc need help


Are you using windows XP or Vista. You should not have a problem if after you do a full system recovery, you add any service pack updates. Download these first and burn to a disk. Also make sure that all the drivers get reinstalled ok. After doing the recovery go into system device manager to see if your network card is installed even if it is a internal one on your motherboard.

If your connection is wireless you may need to setup a wired connection first from the router.

Time warner roadrunner usually works right away with little problems.

If it is a network drive. I believe it must have an IP address.

The best way to start troubleshotting is to know the ip address

Then you can ping the Ip address to know if your computer can see the drive.

If the ping time out...then the drive is not on the network.

If the ping reply then it is on the network. so you'll need to look at the share.
