No IPV6 on broadcom wireless

I have ipv6 enabled on my router with radvd running. All wired computers acquire ipv6 addresses and can route v6 packets fine. Wireless laptop with Intel wireless chipset also works fine. Linux mint on a Dell Mini 10 (Broadcom 4312) chip does not acquire V6 address. Manually setting V6 address does not work either.
