IPv6 connections timeout

[ppparadox]

Hi, i'm having issues with IPv6 connectivity. I already posted all the details here ---> http://ubuntuforums.org/showthread.php?t=2258021

Just a small update:
The router was set to autoconf IPv6 before (as shown in the ubuntuforums thread above) and i was experiencing timeouts both on windows and linux; now using DHCP i get no timeouts on windows but no ipv6 connectivity on linux (i appear to have a global address but i get "network unreachable" errors anyway).

It looks like i managed to solve this after posting where knowledgeble people are. :mad:
I fixed the issue after manually modifying a configuration file (radvd.conf) inside the router via telnet.
The timing and lifetime of advertisements, solicitations were wrongly set by the vendor.
Not that i hope for an official answer here of course :mad:

Since waiting for an official fix is useless (even after contacting the official support) I'd love to modify the firmware on my own to integrate the suggested changes (see stackexchange link) so that i don't have to telnet into the router each time i turn it on. Where do i start?
