[tech] UniSFA network upgrades

[Felix von Perger]

Hi all,

So you are aware, I have replaced the faulty Microtik wifi router named 
"sharpchin" which was being used in UniSFA with the spare OpenWRT wifi 
router "coromandel". This is due to sharpchin becoming non-functional 
for the duration of approximately 50 seconds at random intervals when in 
use, which has apparently been a problem for several months if not years.

The configuration on coromandel is essentially the same as the previous 
device - there is a single cable from UCC which should be connected to 
the WAN port, which trunks VLANs 1, 3 and 6 (1 is untagged) and bridges 
VLAN 3 to all of its 4 "LAN" switch ports. UCC wifi should be configured 
correctly using RADIUS to samson on both 2.4 and 5GHz channels. The 
UniSFA webcam, TV (trelawney) and PC (deepthought) are all cabled to 
coromandel, and should each have dedicated IPs on the clubroom network.

If there are any problems with UniSFA's network connection following the 
upgrade, please let me know, and I will try to fix it.

Cheers,

Felix [FVP]
