* Yes, drivers are a possibility. The initial drivers can be a little 'rough around the edges,' and I find numerous updates concerning Media Center and graphics on this list. Nothing about internet connection problems, though.
* Your router is a likely source. A lot of people have needed to update their router's firmware for Vista to work properly, but there isn't one for your model. My suggestion would be to remove it from the setup temporarily, connecting your computer directly to the modem and seeing if it makes a difference.
* Be sure to download the latest graphics card driver from Nvidia.
* Norton can be a real pain, and doesn't always stop until it's been uninstalled...disabling isn't enough. Use the Norton Removal Tool and replace it with another security option before discounting it as the problem.
* Does the slow internet problem reside solely with Firefox or are IE, Opera, etc affected as well?
Let us know.
I bought a new Sony Vaio LS 25 E computer with Vista Home Premium & 2 G of RAM. I have it plugged into my DLink DI-634M router (not using the wireless capabilities). Previously, I had a Vaio with Windows XP before and had blazing fast internet and smooth Windows Media Center operation (with 1 G of RAM).
I use Firefox and the internet is painfully slow. Not only that but Windows Media Center is choppy and going through all the menus is slow/choppy/frustrating. I have not changed my ISP provider or anything else since I got the new computer. I use Norton Antivirus but have disabled the phishing filter.
Are there fixes or tweaks I can perform on this otherwise beautiful machine to make it run better? My other applications run pretty well but since I use the internet and WMP most of the time it has been a very frustrating few days...
Could it be my drivers (even though they came preinstalled)? Is it my router? Do I need a Windows Vista compatible one?
