Hey, since you like answering tech questions, here's a good one.
I gained possession of a Dell M6400 laptop at work. It's a beast. I planned to make it an upgrade on my existing laptop. It came with a wireless-G card and software called Dell Control Point to manage my connections. The issue is it would connect and make all my other devices flakey at home, also it would take about 3-10 minutes to connect properly. I originally thought the problem was just the software and I generally hate preloaded windows in new computers so I bought and installed Windows 7 Pro which works beautifully in every shape or form, unless I'm using the wireless. I've researched this issue at length and I have all the latest firmware updates.
Long story made short, when this wireless card tries to connect, it kicks off every other device on the network. My home network is a Cisco router with 4-5 devices attached to it. I brought it to work and it managed to knock 30+ wireless connections offline... without even trying to attempt to put in the password.
My buddy thought I was bullshitting him. Thus I brought the laptop to his work yesterday and with him watching, I doubled clicked on their Wi-Fi connection and their helpdesk got 50+ calls within a few minutes as my laptop managed to knock EVERY SINGLE ONE OF THEIR WIRELESS CONNECTIONS OFFLINE until I decided to disconnect.
I repeated this today at Starbucks and watched 10+ people complain to management about the lack of internet while I surfed and drank my coffee.
What do you believe is this issue and should I really try to fix this? I mean, it's no biggie to use ethernet on the laptop either at work or at home. It just may be an issue at client sites. And... I do enjoy fucking up other people's internet access. Maybe the card is defective or can it be an issue with the new OFDM?
