Error releasing the current IP address: The system cannot find the file specified.

[OtherBen]

hi guys!

been having trouble with my internet connection in the last few days. prior to these problems, my internet has been running fine.

upon a restart there was no connection. windows is configuring my connection settings and a shift to the wireless card was no help. upon a diagnostic check i was receiving the 'Error releasing the current IP address: The system cannot find the file specified.' message with zeroes in the IP address.

i left it overnight and today i restored the router to factory settings just in case. the wired ethernet connection on my housemate's computer is fine, as is any other laptop that is connecting wirelessly.

i thought it may have been a wireless card problem but using an adapter brings no change. however, when left (using obatain ip address settings automatically) i will eventually receive a connection, albeit when i load pages up they are drastically slow (dial up slow) or fail to load with a 'page load error'.

it may be helpful to note i also had a trojan recently but have run malwarebytes anti-malware and each time it returns two trojan.agents in the registry data which are there EVERYTIME i run the scan.

i am using microsoft windows xp. and a belkin wireless 54mbps desktop adapter which is 'working properly' apparently.

an ipconfig /all run brings up these results;

TCP/IP stack repair options for use with Windows XP with SP2/SP3.

Start, Run, CMD to open a command prompt:

In the command prompt window that opens, type type the following commands:

Note: Type only the text in bold for the following commands.

Reset TCP/IP stack to installation defaults, type: netsh int ip reset reset.log

Reset WINSOCK entries to installation defaults, type: netsh winsock reset catalog

Reboot the machine.



Then I'd like to see the results of this with no other computers running. When you do this test, connect with a wired connection directly to the router.

Register at DSLReports and run their Line Quality Tests. It's best to run this test with a direct wired connection to eliminate any wireless issues from the results. It's useful many times to run this test several times, and we'd like to see each of the results. Post the results link from the top of the test display page for each test run here.

The link to post is near the top of the page and looks like:

If you wish to post this result to a forum, please copy/paste this URL
http://www.dslreports.com/linequality/nil/2357195 <- sample only, yours will obviously be different!
and your IP will be disguised.

Copy/paste that link here.

Note: You will have to enable PING (ICMP) request response either in your router (if you have one), or in your computer's firewall for direct modem connections. This is very important to get the most important part of the test to run.

this may be a silly question, but can i do the speed test with any computer as long as all the others are turned off? as it would prove to be quite a lot of trouble to wire mine up to the router, but could use my housemates?

Well, that's better than nothing, and will show if it's the ISP that's the issue.
