RT-AC68U - Very slow UI interface when accessing via HTTPS

[rick155]

Hi,

my RT-AC68U is configured to use HTTPS for UI interface (LAN only) and I am struggling with its slow UI interface.

I know that HTTPS access is supposed to be slower, but the difference between HTTP and HTTPS is so high that makes me believe I might have something not configured correctly.

I am using a pc connected via ethernet directly to the router.

With HTTP I can go from one page to another instantly. No loading, no waiting.
With HTTPS it takes at least 10 seconds (average is between 15 and 20 seconds) to switch from one page to another. Sometimes even just reloading the network map (less than 10 clients) can take 40/50 seconds.

In my network normally there are these connected elements: 4 low traffic pc, 2 phones connected, an IP camera (not allowed to WAN) and a Raspberry Pi (running PiHole). Sporadically there might be additional 3 clients (NAS, a network printer and another pc, currently all turned off).

Router is running OpenVPN server to allow remote connection for 2 laptops, but those are currently turned off.

I don't even see too much data inbound/outbound so I assume router CPU is not overloaded handling traffic.

My two questions:

1) Is this expected? Is there anything I can try to make UI faster?
2) Would it be unsafe to switch authentication to HTTP? I connect to router only via LAN (no WAN).

Thanks in advance

no to both
it is not expected and you shouldn't see any differences and not unsafe within your intranet.

What @Grisu said.

Maybe the next time you reset to factory defaults and configure from scratch, https access will work better.

Meanwhile, http access from your LAN is no less secure than your LAN and your router login credentials.

Thanks. Will use HTTP for authentication

Possible reason: Acronis Protection
I had the same problem and noticed that the web interface is loading normally on my phone even when using https. I then tried to deactivate Acronis Protection (part of my Acronis backup solution). The interface then loaded normally on my laptop.
Not sure why; it might be the odd 8443 port or something.
Try and load your router interface on a phone or different machine to see whether it is a router or access device problem.
