I have a DGL-4500 connected to an ATT DSL modem (2wire2700). Prior to installing the router, I was getting speeds of 6Mbps down/.6Mbps up (using speednet). To install the DGL-4500, I changed the 2wire modem to bridge mode. It appears to be correct since I can get an internet connection. After installing the DGL-4500 I now get a maximum speed of about 1.3Mbps down/.6Mbps up. I installed the 1.22b02 beta software hoping it would fix the problem. Any suggestions on what I should look at to determine the problem. Thanks in advance.
