Wierd internet connectivity problem- Random sites have become inaccessible

[basedude]

Hi there,
I have been connected to an open wireless network via my linksys adapter for the last few months and have had consistant internet access with no major problems. Then a couple of days ago I lost connection to random sites like hotmail {I reach the sign in page but cant access my account}, google amongst a whole bunch of other random sites.The operation "times out". I am also unable to ping these sites.I had that pesky Marketsore/osmim.dll problem on my machine which I successfully removed yesterday and ran the LSP fix but the problem remains. I have anti virus installed as well as a host of anti spy and registry cleaner software installled which I run regualarly.
Why would some websites suddenly become unaccessible?? It it possible that the user whos access point Im connected to, has somehow blocked these sites??? Is there any options I can try to rectify this problem??
Thanks in advance!!!!

ps - Im running XP Pro with a firefox browser and have windows firewall running.

open wireless network

Did you talk to other people in the network if they experience the same problems?

I think your system is probably still infected. Try eScan, a free anti-malware tool, which uses the kaspersky-virusdatabase:

If there is still something running on your system, eScan should find it. Also, use HijackThis!. If they both say your system is clean and the problem still exists, we can continue.

And this folks, is why you need to learn to setup security and encryption on your wireless routers.

I ran escan and deleted a few iminor issues. I also ran HijackThis and nothing seems to be out of the ordinary.........or is there?. Here is the log

Look clean to me.

Maybe your problem has something to do with the MTU:

http://www.dslreports.com/faq/5793

You can set the MTU with the tool DRTCP:

http://www.dslreports.com/faq/578

If other people in the network experience the same sort of problems, then maybe the MTU in the router is not set correctly. (Did you ever talk to the admin about your problem?)

you need to learn to setup security and encryption on your wireless routers.

What does this have to do with his actual problem?

I cant talk to anyone else on the network as I dont know who they are. This is just a random wireless internet access point that my linksys can pick up.

I tried tweaking MTU as you suggested but still know change.

Yesterday I reset my tcp/ip settings with the "netsh int ip reset resetlog.txt" command and I was able to access google for a little while b4 it started to time out again. Still couldnt access other random sites even when I had google for a while.
This is really starting to bug me :(
Could uninstalling/reinstalling XP Networking services do the trick? Id like to do this as a last resort though.

Did you restart your computer?

Btw:

Notice what 'BillPStudios' says: "This is one of those stubborn programs which can really cause a problem when you try and remove it." and "When you run LSPFix tell is to move osmim.dll and nothing else. "

Of course :cheesy:

Michael

He can't ask them because he is stealing their bandwidth. Kind of like asking the cops to help you find your pot, so he's trying to get you to do it. My comment was not about his problem, because he IS the problem. Do you get it now?

[pcschrottie]

he is stealing their bandwidth

Well I first assumed that it's an university network or something similar.
