I just got a new wireless router so I could be able to connect my pc in the house to the office network, but the signal strength is terrible. I loose more than 50% over a distance of 10m going trough 2 external walls? Is this normal signal loss? Ive looked at adding a AP but im sure that a wireless network should be able to function further that 10m? The router is a D-Link DSL-2650U and the pci card is a D-Link DWA-525 Wireless N 150 PCI Adapter. Please help!
