network continues to switch on/off on an intermittent basis DNS issue Farbar says there is another connection that I am not awa issue

[tiano]

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.

 

 

It seems that there is a second Wireless connection that I am not aware of, because I don't see it,

Farbar says there is another. I also found with Dr.Web Scanner Trojan.Siggen4.58009 on my (batteryCare) program.

 

Help would be appreciated

Thank you

I had a very similar situation happen to me a few years back with a U.S. Robotics router. I would intermentally loose my connection and then it would try to reconect. Sometimes sucessfully, sometimes not. This got progressively worse as I was trying in vain to figure just what the heak was going on! As it turned out it was the AC to DC plug-in power supply to the router that was going bad!

The best way to ascertain something like that would be to see if any other devices also connected wirelessly to the same router are having similar issues....

I suggest statically setting the WiFi NIC, as a test, to an address on your sub-net and add the following DNS servers to the NIC's DNS table...

 

8.8.8.8

8.8.4.4

4.2.2.3

4.2.2.1

 

If that resolves the issue, you may want to add them to the your Router's DNS table for DHCP.  Then you can revert back to Dynamic addressing on the WiFi NIC and it will be using those addresses.
