Alright, so this is an interesting one.
I have recently moved into a new shared house, and decided to upgrade the ISP provided single-band TriplePlay150 by hooking a brand new D-Link Viper AC2900AL (It's fancy, fast and I got it at half price via work.). First day, everything went absolutely fantastic. 5 GHz and 2.4 GHz went up without a hitch, we have aprox. 12 devices (PC's, phones and a couple consoles) connected max. At any time, things were also flawless for online gaming. Everything worked.
Two days later, I return from work to discover that devices can't connect to 5 GHz at all. Quite simply, either you'd put the password in and it'd time out (My TP-Link Config. Utility spends 60 seconds connecting, then tells me the factory-reset password is incorrect), or you'd connect with no internet access and drop out 10 seconds later. 2.4 GHz, which was stable enough for gaming previously, can still download at very high speeds, and works relatively well for everything excluding gaming. Upon joining anything online related, I will enjoy >80ms ping for all of 5 seconds before crippling lag spikes every 5 seconds makes it unplayable and usually get me booted off.
(Thinking maybe the "11-25+ Devices" rating on the modem was ambitious, I tried disconnecting all devices bar mine, same issue regardless.)
However, to fantastically complicate matters, the landlady has no idea what her ISP user/pass are, and doesn't want to contact them to find it out. This means I can't access and direct configurations on the AC2900 or TriplePlay150. This also means setting the AC2900 up in place of the TriplePlay isn't available, as the setup wizard requires the ISP user/pass as well. I'm attempting to resolve that, but in short I feel this problem is unrelated as it was working crystal clear for a few days before problems arose. However, i will be working on getting that problem fixed sometime very soon. In the meantime, I can unhook my AC2900 from the internet, and mess with anything settings wise on the router that way.
This is going to be tricky; I honestly don't expect much in the way of a solution. However, any help to see if I can get my 5 GHz band working again would be greatly appreciated, let alone an explanation as to why it worked in the first place.
What is being used:
D-link Viper AC2900AL (Set up as a UFB Residential Gateway), set up <8m down a clear hallway.
Windows 10
Using a TP-Link Archer T6E Wireless card
Connection is via Chorus UFB Fiber.
WAN for the Viper is provided through a TriplePlay150 ISP provided modem, single 2.4 GHz band.
If you need more specs, just ask.
Side note, setting the Viper up over WAN has made VOIP vanish, so the phone doesn't work on this side of the house. It's not critically important, but I feel as though my relative inexperience did that. Not sure why.
All drivers have been triple checked, firmware was manually updated on the Viper AC2900 to v1.01.00.
Thanks for your time,
