This is my scenario...

We have DSL, connected up to a 4-port wireless netgear router. Two computers are wired, and the laptop is wireless. Both my computer and the laptop connect and access the internet fine, however the other wired computer is having problems. At first it just lost the internet, then was coming up with limited or no connectivity. (the other computers work fine still) Then I did a winsockxp fix, reset the router and the dsl, still same problem. Used XP to configure network again on problem computer, and now have it connecting to the network and to the internet, however it is abnormally slow on the problem computer(other computers work fine and fast too). I then did a ping of the router (192.168.0.1) and it's weird, I will get a request timed out, followed by a 2 replies and a timeout, or vice versa. I'm getting a range of packet loss from 25% to 75%. I am at a loss as to what may be wrong with that computer, or how to go about fixing it?
Any ideas?

Hello micky,

Please do the following commands, and copy/paste the results into your next reply.

Goto Start, Run, type CMD, press 'OK' and then type: IPCONFIG /ALL - please post the results here by right-clicking on the Command Prompt window, selecting 'Select All', pressing Ctrl+C, and then posting on this forum.

Please goto Start, Run, type CMD and press 'OK' - now type: netstat -rn and press enter; please post the results here.

Goto Start, Run, type CMD, press 'OK' and then perform a Trace route by typing: Tracert location - ie: Tracert Yahoo.com
Once the trace has completed, please post the results here by right-clicking on the window, selecting 'Select All', and then pressing Ctrl+C; post the results here.

Test your Network
1. Goto Start, Run, type: NETSH DIAG GUI - press 'OK'. A Command Prompt window will open temporarily; don't touch it, it will disappear in a moment.
2. A Microsoft Help and Support window will then open; select the option 'Scan your system'.
3. Wait for the scan to finish and then scroll down to the heading 'Modems and Network Adapters'. Look at 'Network Adapters' (don't expand it yet). Beside your connection information, you should see a green 'PASSED'; if you do not (if you see a red 'FAILED') then expand 'Network Adapters', scroll down the list until you see the heading with the 'FAILED', expand that option and copy and paste the results here.
(Please also look for any other 'FAILED' in the scan report, and post the information relating to it)

Thanks,
Dan.

Hello micky,
You're losing packets before you even reach your router...

Please try to plug your computer directly into the modem (if possible) and attempt another pathping to yahoo.com.

Please also download HijackThis and install it on the 'problem' computer. Please perform a scan, and then from the log file, please copy/paste all 'Running Processes' (please do not post the entire log).

Also, please ensure that your computer is free of malware by following the steps located here.

Please download LSPFix from here. Run it on the problem computer, and please tell me what is under the 'Keep' list, and also the 'Remove' list. Please do not click 'Finish'; simply close the program by pressing ALT+F4 or pressing the Close (Orange square, white X) button.

Thanks,
Dan.

Have run the malware programs as well, came up with some stuff, so hopefully this gets solved shortly!

Did you post a full HJT log on the Malware Removal forum? It would be nice to get an experts assurance that your computer is clean.

If you have not, then please do so by posting here.

Thanks,

Guys,

How do I find out bandwidth sent and received? We are running High speed DSL. Like I said in the beginning post, my computer and the laptop work perfectly fine, but the other computer has the issue, which leads me to believe either malware or hardware problem, but I guess we're working through it to the solution.

Thanks guys,
mick

it could be a malware problem or there could be a program like a game or a running process that could be straing your pc and/or internet at the same time. go to www.cnet.com or do a search for bandwidth and search for a bandwidthspeed test and it will tell you your bandwidth curretly.

Still losing packets.

Hello micky,

Please goto Start, Run, type CMD, press 'OK'. Now type: netstat -s -p tcp
Copy and paste the results.

Please download PingPlotter. Don't run it yet.

Now, please restart your computer into 'Safe Mode with Networking'.

Run PingPlotter, and perform a trace to Yahoo.com, or Google.com. Please save the results and post them on your next reply.

Thanks,
Dan.

Dan G.,

The information you provided for conducting tests provided me with enough information to solve a similar problem.

I had to go into the registry and set the DependOnService

1. Click Start, click Run, type regedit, and then click OK.

2. Locate the following registry key.
HKEY_LOCAL_MACHINE\System\ControlSet001\Services\DHCP

3. In the right pane, double click DependOnService, and then make sure that the Data Value value is Tcpip Afd NetBT

Thank you.
