doesnt matter which browser i'm using, i think the ipv6 routing to youtube is borked. did an ipv6 speed test and it was slightly faster than ipv4. all ipv6 sites had normal speed except for youtube.

why by default my ipv6 showing no internet access ?
until I go ipv6 website test, then only show got internet
what wrong ?
on l7 router, already enable ipv6 @@

Does it work in Safe Mode ? Could be a windows bug or a driver issue or an antivirus..

I didn't try

this is normal, you do not have to worry about this.

so is unifi issue or computer issue ??

Computer issue.

lol but sometimes automatically showing ipv6 got internet
any solution to fix it ?

No, just leave it be and it will fix itself.

Just enable IPv6 on my RT-N16 with the MTU change and testing

Successfully enabled my IPv6 on my Innacom W3400V6 provided by TM.



However, I think loading web pages is slower than normal. Speed test and ping very okay. I just don't know what's the benefits of this IPv6 instead of letting got TM more control over our internet usage.

However, after I change my DNS server using Google public DNS as follows,



Loading web pages seems faster...

To Tomato Firmware users,

My setup
Asus RT-N16
Tomato Firmware v1.28.7501 MIPSR2Toastman-RT K26 USB VLAN-VPN-NOCAT

Here's my config:
Basic > IPv6
- IPv6 Service Type: DHCPv6 with Prefix Delegation
- Prefix Length: 64
- Static DNS:
|-> 2001:470:20::2
|-> 2001:4860:4860::8888
|-> 2001:4860:4860::8844
- Enable Router Advertisements: Enable
- Accept RA from: WAN

After tinkering around, I found editing "/proc/sys/net/ipv6/conf/br0/mtu" directly gives me mix result.
I solved my problem by adding "AdvLinkMTU 1480;" into "/etc/radvd.conf"
But I'm not sure about other Tomato builds but I found out that the router advertisement daemon (radvd) in my version overwrites "/etc/radvd.conf" everytime its starts up. I couldn't find the setting in the nvram dump that toggles AdvLinkMTU for radvd.conf.

So I wrote is this simple script and added it into
Administration > Scripts > WAN Up

or you can put it on a cronjob or Administration > Scheduler to constantly check on it
in which you can remove "sleep 5;"

also, I didn't change the WAN (ppp0) MTU setting. (still on default, 1492)

Hi, anyone from USJ? Wonder if ipv6 is available in USJ already.

I'm sorry, do you mean IPv6 would only be accessible after 10-15 minutes of authenticated into screamyx ?

If so, no. I can access IPv6 sites immediately after login.
I think the problem might be becuz the OS still retains the previous IPv6 address. (becuz a different prefix is dynamically delegated each time you connect to TM). In theory, "ipconfig /release6" and "ipconfig /renew6" into command line should solve the problem. But in my case, it doesnt work so my workaround is to go to the network's Properties and uncheck"Internet Protocol Version 6 (TCP/IPv6) to disable IPv6. Than go back and reenable it .


Side note: I modified the script cuz there was a logic error

when you do, try going into CMD and check ipconfig to see whether or not you have 2 sets "IPv6 Address" and "Temporary IPv6 Address" with different /64 subnets
but after 10-15minutes (when you can access ipv6), try again and check if only 1 set of ip address are left

I modify my original post but here is again
