I have a new laptop, a Samsung NP300V5AH, Core i7, 4 GB RAM, 1 GB NVIDIA, and 64-bit Windows 7 Home Premium. It works perfectly fine but internet browsing is extremely slow. This is specifically the wireless browsing that's slow. When I connect with a cable, it's much faster. I have a fast internet connection that works great on wireless with my other, even older laptops, but for some reason it's slow on this one. It makes no difference if there are no other devices connected, whether I'm close to the router or not, what the signals are like - it's slow anyways. I have a Dlink router (DIR-618) and I've called the Dlink people about this but besides minor adjustments in the router settings, they can't do much considering other devices work just fine. I've tried a router reset, to no avail. I've tried Mozilla and Google Chrome as well, but changing browsers doesn't make a difference either. I'm running Norton Internet Security 188.8.131.52. Any help I could get on this would be greatly appreciated.
