[BUGS] Net network performance question?

[Dean Hamstead]

Friends dont let friends run the ISP modem :)

Also, realistically WiFi will run at about 50% of its theoretical max speed.

Telstra's modems are notoriously terrible (as are most big name ISP's 
who customize the firmware), but on the plus side Telstra is now perhaps 
the only ISP that does IPv6 on NBN and ADSL products (Internode doesnt 
do it on products they are selling through AAPT wholesale, like NBN-HFC 
and NBN-FTTC)

If you don't use a phone service which Telstra insists on providing via 
their crappy modem - you can just replace it with something like a cheap 
TP-Link. Which you can likely reload with OpenWRT or similar. If youre 
using fttn then youll need to get a vdsl modem (even just a 1 port dm200 
from netgear, in bridge mode).

Or you could run a pfsense/opnsense appliance, or roll your own via and 
bsd you like. For

I've not yet had the chance to get Telstra IPv6 running on a non-Telstra 
device though. Assuming they are just using DHCPv6 (they just use DHCP 
for ipv4) then it should just be a matter of providing settings they 
will accept.
