I bought a D-LINK DI-713P Wireless Router to use with the DWL-650 and I was very disappointed with the 650. Signal degradation was immediate (30%) after only 30 feet. This was with Encryption TURNED OFF! I tried using another brand wireless card and was able to go all over my house (over 2000 sq ft) without any dropped signals. DLink makes a great wireless router DI-713P. Too bad I can't say the same about the DWL-650.
