IPV6 on an ASUS router

Phillip22 — Sun, 09 Aug 2026 16:25:58 GMT

Hi,

I recently changed my router from the Sky Hub 4.2 I believe, after having ipv6 disabled always and limiting the router to its bare essentials (moving dhcp to another pc etc).

The main reason for getting a new router, was to finally enable IPV6 where I could actually set information from the RA's sent across the network.

However, after a lot of debugging, I found the router doesn't play well with ipv6, where every 10-20 minutes, the internet will drop for services, mainly social media, and this causes videos and post data to hang loading.

I think I have isolated it to be a lease time problem with IPV6, so TCP connections will then fail, causing hangs.

Here was my config (excluding the prefix)

@Phillip22 from a quick look perhaps it's Sky dropping the lease as they can't see the router?

Go to Advanced Settings > WAN.

Scroll to the bottom of the page to find DHCP query frequency.

Change this from Normal Mode to Aggressive Mode.

I've actually set it to continuous, since aggressive was the default

Continous seems to have fixed it, devices now sticky their ip's and the prefix hasn't changed for 24 hours.
