I've been having trouble with the internet connection speed on my Mac. I originally noticed the problem when my mail kept timing out whenever I sent an attachment, I went to different forums trying to find the solution but nothing really worked, so I found work arounds for the email and lived with it. Recently the company I work for moved offices and I was no longer behind the RV082 and my internet ran better dispite the slower connection. Once we finished moving, I needed to use the Dual Wan Load Balance feature of th RV082 so I set it up in the new office and my internet was slow again. Unfortunatly in the new office there are several more Macs than just mine so I really need to get it working. Currently we have 2 seperate networks for PC and Mac and I really need to get them on 1. Is there a setting I may have overlooked or is it not going to work with Mac. I'm wondering if it a problem with just my router cause I can't find anythign about it online.
It sounds to me that you may be running Leopard or above. One thing to take a look at is IPv6. To keep things simple, disable IPv6 on your Mac (just one) and see if that makes a difference. With 10.5 and later, the move to IPv6 is stepping up, unforntunately some devices just don't play nice. Also do a little Google search on "How to speed up Firefox on Mac" and you will find some articles with steps on how to disable IPv6 on the browser.
