I just received my new xps red ( see below ) and wired connection reads 100mb and wireless i am running 52mb. On my 9150 with an Intel(R) pro/1000 pl network i am reading 1.0 Gbps and on my laptop ( wireless ) i see 300mbps. The technician just left after installing my new wireless 1505 N card ( the first one didn't work ) and now he says its a software issue.
