@Datalink I can confirm that the interface loading time is faster on the CGN3ACSMR w/o the new firmware update. However, I do notice that it is lacking some features such as the ability to change timezones. Does anybody know if the new firmware adds that?
Just got the CGN3ACSMR tonight, its great so far. Testing out the 5G portion... Sent a PM to CommunityHelps just now with the required info and looking forward to being on the latest firmware.
Well... Firmware just got pushed to me. Looks like I found a bug: With this firmware version (184.108.40.206) I cannot run 5Ghz Wi-Fi only. The 2.4 needs to be enabled for the 5 to work. On the firmware it shipped with 5G only wasn't an issue. I'm happy to live with it while it is investigated but I expect it to be fixed. (I am under the impression that this firmware that is being pushed out on request only is still in beta hence it not being released en masse)
I think I noticed the same issue, turn off the 2.4 Ghz wifi and the 5 Ghz LED goes out. Now, the only way to confirm this is to monitor the 5 Ghz network with inSSIDer. This might just be an LED control issue, not necessarily one where the 5 Ghz network stops working. I didn't test for that and probably won't as I run my modem in Bridge mode. Not sure when I can run another test to check it out. Here's the link for the last freebie version of inSSIDer. It doesn't do 802.11ac, but the new pay version does, and is worth the $20 U.S. if you use 802.11ac networks. You don't need an 802.11ac capable laptop as the program reads the transmit headers and displays the a/n/ac networks in the 5 Ghz band.
Nope I tested and confirmed, with 2.4Ghz off and 5Ghz on, neither the 2.4 or 5 Ghz networks show up to either my laptop or phone, and the paid version of Inssider does not see them. (Thanks for the recommendation - had paid the $20 for it a while back based on its frequent mention here - I have had 802.11ac routers for the past 2yrs and set it up at clients places alot, and have an 802.11ac capable laptop and desktop. So a worthwile investment)
So its not just the LEDs going out, the actual wi-fi networks go down.
The other thing is, (minor issue) when going to the login screen it says "Undefined" instead of "Username" - just a minor OCD thing.
