Just bought the new generation AE and am getting horrible streaming over wireless network. I replaced a 4th gen AE with the new gen AE as my main router connected to my cable modem. I am now using the fourth gen AE to extend my network range (wirelessly connected to the new generation AE) to extend my network range. Since I upgraded and configured this, I get horrible streaming. When I plug in and use Ethernet from the 4th gen (old) AE, the streaming and download time is extremely fast. Remember, I have the 4th gen AE wirelessly connected to the 5th gen AE (which is connected to modem). Why could I be loosing so much performance on wireless? I know my ISP speed and browser is not the issue since I have no issues when using Ethernet (cable connected to the 4th gen AE). On wireless, I am getting over 300 transmit rate and an RSSI of -53. I am using the 5GHz on 157 channel; 802.11n.
