Incredibly Slow Internet

Recommended Posts

Here's the info:

 

Once i plug this computer into my network, every other PC would lose connection to the internet.

So the first thing i tried doing was to remove and replace the network card with a brand new one and install the drivers.

This has stopped the rest of the PC's going down from the internet but now there seems to be a big problem with the machine itself.

 

Basically the internet on this machine has gone down to like dial up speeds or worse.

Internet pages take 10 seconds to load > Sometimes they won't load at all > It will sit there with website found, waiting for reply. Before not finding the page.

Things like Anti Virus updates > Windows Genuine Advantage > Microsoft Games wont load sometimes or they can take minutes to connect.

 

I have tried turning off AVG Anti Virus / Different Web Browser / Different Network cable / Different Network Card / Different Software/Drivers / SFC /SCANNOW > CHKDSK > Repairing the connection does nothing (Infact sometimes it wont even renew the IP but will still have a connection?)

 

There is no firewall installed / Windows Firewall is turned off.

 

No virus's or spyware or anything. Its completely clean.

 

Anyone have any idea's i could try?

One thing i also wanted to add which i thought was rather strange.

 

There is only one internet browser installed on the machine, but every now and then the Microsoft check appears asking to make IE the default browser?

Also i should mention Symantec Live Update is installed as a part of Symantec Anywhere . . but this program i have been told is needed.

what type of pc is it? if all the other pcs lose connectivity when you plug it in, is it trying to assign ip addresses to other machines? What OS? go into the command line and type 'ipconfig' and see if the ip scheme matches what your router is giving out. I don't know for sure but it's something to check.

sounds like spyware, usually they are IE based and use IE processes even if you cant see any windows open. I know you said its clean but it probably isnt. a lot of spyware doesnt get detected in scans and doesnt show any visual signs. symptoms are 100% spyware.

 

try making a new user account on the same computer and using that, or try using safe mode with networking enabled. ultimately gogo reinstall windows.

 

Even if its not spyware, its almost definately software, so fresh installing windows should fix it, and it doesnt take very long.

Try this: go to start > run > type in "cmd" and hit enter > type "ipconfig /flushdns" > type "netsh winsock reset" > then restart the PC and see if that helped any.

I have this problem after brownouts. I just unplug the router for about 5 minutes, plug it back in, and the problem is fixed.

Flareback: The machine is a Dell with Windows XP Professional installed. The IP settings are fine and are what they should be.

 

Invidious: I have tried various accounts / I have tried Safe Mode with Networking (This worked once) / I have run Hijackthis / AVG Anti Spyware full scan and it seems to be 100% clean. Reinstalling Windows is the last option as this PC is used for Sage accounts.

 

Nerm: Just tried that buddy and it seemed to open my home page quickly before it happened again.

 

Bleeble: This PC was taking down a Office Network so i took it back to our office to fix it and it brings down ours aswell. Aint the router dude.

I removed the Symantec crap and the problem persists.

 

One thing i did notice was that Tiscali internet was installed and IE was showing as Tiscali Internet browser. I have since removed that aswell but the problem persists.

 

Any new ideas to try guys?

well if you have a spare drive you could try a clean install and see if that works....... if it does then you know its something in the software

A linux live-cd might do the trick too. If it connects fine with a live CD, the drivers could be to blame as well.
