Well, I've actually been having close to zero issues with my DGL-5500 since updating to 1.13b4 back in April. A few instances of not seeing my devices listed in Active Devices, but nothing a router reset didn't fix. ABE had my US/DS perfect, and speeds across all my devices were great, and for the most part in line with my 30Mbps/5Mbps advertised speeds.
Yesterday morning my ISP (Time Warner) enabled my new MAXX speeds (200Mbps/20Mbps). This morning I noticed that I was not seeing these speed increases on any of my devices - including my wired PC.
First thing I tried was a direct connection between my Arris DG1670A modem and my PC. Ran the speed tests at speedtest.net and the Time Warner speed test, and it accurately reflected my speed increase.
I factory reset my DGL-5500 (following the steps always outlined by FurryNutz) and the bandwidth test upon setup only came back around 30Mbps down, but the up speeds were ~20Mbps. Now, it looks like the ABE is still in "Testing" mode, and as of right now it's showing ~80Mbps down (up is still correct).
I guess my question is - is this normal behavior? As in it's been testing for about 10 hours now. Will leaving it testing eventually get it up to my 200Mbps speeds?
