For 3 days my magicJack (internet phone that connects to a computer via USB) had been giving me a bad connection sporadically. I could hear them but the person on the other end couldn't hear me. Yesterday morning I decided to reset my router in an attempt to bring my calls back up to normal quality. Unfortunately, the connection on my computer has been extremely unstable ever since.

I will connect to sites with normal speed about 10% of the time. About 40% of the time it is incredibly slow - as in it takes 1 to 2 minutes to load pages that normally take about 2 seconds - and 50% of the time it doesn't work at all. When it doesn't work at all my browser (Firefox 3.6-something) says "Server not found," and less often "The connection was reset." My connection seems to switch between these three states frequently and fairly randomly.

1) Without a reasonably usable connection, I decided to run a virus scan of my computer to see if I might have something malicious causing the issue. A full scan of my system with an updated Malwarebytes produced 0 infections.

2) I tried resetting the modem and router 2 more times, while also restarting my computer to no avail.

3) In the afternoon my housemate arrived home and checked her computer. At first it seemed fine, but soon enough we were able to confirm she was affected by the same instability. We decided to contact Charter (our ISP) to reset our connection from their end. Afterwards and since then her connection has been back to normal. My computer, on the other hand, is still experiencing the same issue. So I am typing this to you from her computer for the sake of my sanity. We are both on the same network and connected wirelessly. She is running Chrome and IE on Vista 32-bit, and I am running Firefox 3.6 and IE9 on Windows 7 64-bit.


In one of numerous online chats with Charter last night, one of the technicians told me to try the following command in the command prompt:
netsh int ip reset c:\resetlog.txt
It did whatever it was supposed to successfully, and I restarted my computer as prompted. However, nothing has changed with the problem.

This morning I woke up to my computer having restarted itself to complete Windows updates. The problem seemed to have been fixed by the updates because my connection was temporarily completely back to normal. Joyous, I got some breakfast, then brought the magicJack back to my computer (I had hooked up it to my housemate's computer last night so I could make calls). Then, suddenly the unstability reared its ugly head again and hasn't gone away since. Of course I detached the magicJack and restarted my computer, but still the problem exists. I feel it was just a coincidence that it played out that way, but felt it was worth bringing up.

Other Symptoms:
1) I have noticed flickering of the mouse at times, something I definitely don't normally experience.
2) The sound on mp3s as well as video files will sometimes make a short machine-gun burst stutter effect on whatever sound is currently playing. It seems as sporadic as the connection problem, and again, not normal for my computer at all. I've also noticed pausing the video or audio for a minute or two seems to greatly decrease the frequency of this symptom.

Please help me! I need my computer for my job as I work from home, and this very odd internet issue is seriously cramping my ability to work. Just in case it's important, when I type ipconfig into the command prompt of the problem computer it yields the following:
IP: 10.0.0.5
subnet: 255.255.255.0
default gateway: 10.0.0.1

Thanks!

Updated April 18, 2011:
I decided to review some other threads with relatively similar sounding problems that have received replies and take initiative with some of the troubleshooting steps requested by G2G techs.

Below you will find a link to a screenshot of Xirrus Wi-Fi Inspector running on the trouble computer, followed by three pings in the command prompt and the results of "ipconfig /all"

Note: My connection seemed to actively be going between normal and severe latency as I was taking these pings. I did a few more a moment later and it said the host could not be found. Then, another moment later I tried the default gateway (10.0.0.1) and google.com again and got 0 packets lost in both with 9ms and 37ms average latency respectively. This connection is all over the place...
