So I pulled out my DGL-5500 earlier today and put back my DIR-857. The DIR-857 works a lot better for me regarding speed and wireless strength/performance. Not sure why. I have the settings the same way. I then saw your post and decided to give the DGL-5500 a shot with the new firmware. I followed your steps of resetting the router, applying the new FW, reapplying all the settings manually, rebooting, etc.I have IE10 in Windows7x64. I didn't have any issues with my browser as Fuzzy described. I do not have a HDD connected. In all honesty, I am still having the performance issues on my Wireless using the DGL-5500. It is almost unusable on my 2.4Ghz band (I have 100MB/20MB service but speedtest was showing <1MB/1MB on wireless 2.4GHz). The 5Ghz band seems to be ok but still no where getting my LAN speeds. I also did not get accurate measurements using their speed test in the SB page. I tried with ABE on and without. It is better without when using SB for me. Not any different from old FW unfortunately.I am not sure why this router's performance is so bad for me compared to the DIR-857. I really like the idea of SB on the DGL-5500. I was hoping the new FW 1.10 would have fixed some of these performance issues, but it doesn't seem to have really addressed any of that stuff.
