Okay, received a replacement N750 setup w/ orig firmware. I used my browser vs. CD for setup. Default firmware shows only 15 remaining slots left for QoS setup, which is correct. However, once the latest firmware is installed & you Reset to Factory via Advanced Settings --> Admin --> System or by depressing the Reset button for longer than 10 seconds, FasTrack QoS shows a default of 23 remaining slots left for QoS setup, with things like Apple FaceTime, BitTorrent & games (e.g., XBox Live, Call of Duty), etc. disappear. No matter how many times you Reset via software, FasTrack QoS settings always show this new default… which is a bug. You can restore the full 17 preset apps by first reflashing the router w/ the original firmware from the Recovery folder of the installation CD it came with. Once you update to the latest firmware, these 17 preset apps remain so long as you _don’t_ attempt to then reset to factory settings.
This is repeatable 100% & can be easily confirmed by Tech Support. Is it possible this can be escalated to them for a definite fix w/ updated firmware for the N750? Thanks.
There may be a small memory leak w/ the latest firmware when both Parental Controls & FasTrack QoS are Enabled where sometimes DNS information is forwarded, but the router hiccups & none of my wireless devices can complete loading of a webpage (PC, Mac, iPhone 5, iPod touch 4gens, Nintedo DSi/3DS) until the hiccup is resolved or a hard reboot of the router is performed. I say may because this may also be tied to my ISP’s DNS setup. I’ve used Verizon’s/Level 3’s 126.96.36.199/188.8.131.52 & I’ve not noticed this as much or the duration isn’t as long. I’ve just turned both Parental Controls & FasTrack QoS off since I don’t have more time to test. If anything, the aforementioned reset bug is definitely something that should be fixed (and may resolve other issues & seems like a very easy fix).
