Looks like we could be having issues with overloading our internal DNS servers. So in preferences swap the two IP addresses round via
System Preferences...
, Network
Advanced...
, DNS
. Swap 10.200.95.200
& 10.200.95.200
round. As an alternative could use
8.8.8.8
& 8.8.4.4
from Google - however this depends on how many internal services you need and wether you’re happy to add these
manually to /etc/hosts
.

Try a :
sudo su
Password: *****
touch /etc/sysctl.conf
echo net.link.ether.inet.arp_unicast_lim=0 >> /etc/sysctl.conf
chown root:wheel /etc/sysctl.conf
chmod 0644 /etc/sysctl.conf
exit
Reboot, then check that the change has ‘stuck’ with a
sudo sysctl -a | grep net.link.ether.inet.arp_unicast_lim
The values should be 0
, not 5
.

We’re having network issues. It looks like out local AP is overprovisioned - 80 connections .v. a capacity of about 30.
1: (Temporarily) stop using the guest WiFi for their personal phones [Unless they are using them for Application testing] 2: Where possible use LAN not WiFi and disable WiFi
There are a few of us who have already been LAN only (WiFi disabled) who have experienced network wobbles – however, as we discussed this could be due to backbone over-utilization.
As an aside, a mobile
SSID would be excellent.
PS: Would there be any (short term) advantage to getting a 4G MiFi for use by mobile – it could probably take 5-10 testers off the WiFi?
