Hi,
 

I hope someone can help me to understand and resolve this issue.

 

I am experiencing some issues with my wireless for the past week I still haven’t found a solution for the problem, at first I thought that could have catch some type of adware because I got some window pop up on my browser and since then I have been having issues with my wireless on my laptop. I have run a test to see if I have adware, malware or any viruses but the end results are clean.

 

So far the issue I have with the wireless is a headache, the connection seem to be stable for a certain period of time and then drops, when it drops the reload wheel keep spinning and spinning and after a few seconds I get the yellow question mark in my wireless bar, then the connection timed out for some time (20 to 30 seconds) and gets back, the network continues to switch on/off on an intermittent basis.

When I ran the diagnostic “wireless network connection status” in windows 7 I get the following error

Problems found

“Your Computer appears to be correctly configured, but the device or resource (DNS server) is not responding”

Other times I get another error which it isn’t related to the DNS server issue, but instead is telling me “The connection between your access point, router, or cable modem and the Internet is broken” the estrange thing is that how can the troubleshooting is tells me one thing  and in the other end the internet hasn’t drop still working fine.   

I have run the cmd ipconfig/all and the rest and this didn’t do anything, therefore I am out of tricks to get this thing working.

Help would be appreciated

Thank you

“The connection between your access point, router, or cable modem and the Internet is broken”

If this is true you will have no internet I mean hardware problem.Which programs you have run to see if you have malware?Download Minitoolbox - http://www.bleepingcomputer.com/download/minitoolbox/

Set ticks everywhere and click GO button.After scan is done a log will appear.Save and attach it here.

Ok.I don`t know this,but it is for blocking incoming and outgoing like TCP filter.

PeerBlock 1.2 (r693) (Version: 1.2.0.693)

Also I think you don`t need this:

Free Internet Window Washer

What is the situation in Firewall section of McAfee,because it is Security Suite?

Peerblock , Yes you are right it, is a program for blocking incoming and outgoing TCP’s. I usually don’t use the program that much, but doesn’t affect anything else due that the program is off. My McAfee firewall  I have set up as follows: (NOTE: I have these settings before the whole issue with my wireless and never have any problems with the settings and the network or the wireless)

Thanks,

 

My McAfee software have turn off my windows Firewall, for the same reason that McAfee is taking over that section which is ok, 

 

My computer is a Dell xps 17 (l702x).

 

I have the link for the pop up window that is causing my wireless to drop, I don't see any adware install on my browser or my computer and went a run hitman software, didn't find anything either.
