Hello,
I've been using Ubuntu 12.04 for about nine months or so on my laptop [Dell Inspiron 15R with BCM4313 802.11b/g/n Wireless LAN Controller]. My issue is that my laptop creates a radius of a 'dead' zone whenever I have it connected to the internet, and I've been experiencing this for about a month. For instance, while Ubuntu is wirelessly connected to the internet (home network), my iPhone 3GS won't load anything, even though it shows it's connected to the home network, as nothing will load that requires internet access. However, if I disconnect my laptop from the internet, my iPhone or another laptop around will instantly load anything without issue. The reason I know this is an Ubuntu problem because I also have a Windows 7 partition I can boot into; everything works fine connection wise.
If anyone has any idea what the culprit is, I'll be very pleased!
Also to note, router isn't the issue (in terms of being faulty, fresh one was just bought today and problem is still present). Also tried loading an earlier kernal, no success there either.
Hopefully there is a solution that won't require me to reinstall Ubuntu.
Thanks!
