I'm running two separate rigs next to each other in one room, both on the same network, and consecutive speed testing resulted in 42d/1.58u and 4.87d/7.82u. The wireless card in the slow one is an integrated Broadcom in an Asus P8Z77-V Deluxe Mobo. I've already checked power saver settings, and tried telling it not to search for any new networks once connected (heard that could work). Still, the lowest ping is consistently 10-12ms higher than the machine right next to it with random png spikes up to 2k+ and total connection drops. Any ideas?
