So I've been having a lot of issues with my internet connection since installing 12.04. This is happening on both of my laptops that run this version. My mac has no issues although I did just notice one page that took a while to load. Which brings me to the question. What tools should I get and how would I go about testing whether the issue is at the wireless or the actual internet. Is there something that could monitor and tell me if there are lapses in connection? This whole time I've been assuming that my older laptop (2005) and my netbook are just not getting along with Ubuntu 12.04 but it would be nice to be able to actually test this rather than just assume...even though the mac is good 99% of the time... Maybe the router is conflicting with Ubuntu? Maybe the internet goes in and out? Who knows... Thanks!
The easiest way to tell if it's your wireless network\your laptop wireless interface or if it's your Internet connection is going to be the ping utility.
Here's what you need to do
Take several samples for longer lengths of time if you need to, that will only give you a better idea of what's going on.
If you think the issue might be with your laptop you should try from another computer and see if you get the same or different results.
