I have a DGL-4500 with 1.23NA fw and am experiencing constant disconnects. The connection always says excellent but will just suddenly disappear from my connections list then come back after a few seconds then work for a few seconds and repeat the process again. i have 2 desktops and 1 laptop, 1 desktop with a wired connection that runs perfectly and 1 with a wireless connection which is what I'm having a problem with, and the laptop is also wireless but runs perfectly. All 3 computers have windows 7 but the desktop with a wireless connection is the only computer with a problem. The connection only disconnects while downloading or using any other process that require constant downloading ie. playing browser games, streaming videos, or running multiple windows at once. I have not changed anything in my setup but have only had this problem for the last 2 days. Any ideas would be helpful and I'm not exactly a techie so sorry if i forgot some important information.
