Information Systems:Old Wireless (WiFi) Infrastructure (pre-2017)

Overview

This page describes the current wireless (WLAN) infrastructure at uniPHARM. As of September 2016, there is a business case to redo the entire infrastructure, so the info on this page is slated to change drastically.

There are 3 sets of access points in the current infrastructure: a set of 4 APs for the RF guns, a set of 2 APs for the mobile belt printers used in receiving, and a set of 2 APs for a guest wireless network connected to the Loomis network (DHL/Loomis). All SSIDs operate on the 2.4GHz; there are no 5GHz networks enabled as there is no current need for such.

Wireless networks

SSID	Purpose	AP Group	Security Type	Password	Notes
unitek2	RF gun network	Psion Teklogix 9160 G2	WPA-Enterprise	User: gunuser2, Password: keepscan9	Authentication server is internal RADIUS server within cluster.
uwddc1	Mobile belt printers	Cisco AP541N-K9	WEP	UWDVan20dyke52	Implemented because mobile belt printers had trouble connecting to Psion access points. (I've validated this - the printers don't handle WPA-Enterprise well. -norwizzle (talk))
unioffice2	Guest wireless (Walled garden)	Cisco WAP4410N	WPA2-Personal	Unipharm6y0d	Disabled due to interference

Notes

Issues Log

• Errors related to internal memory/flash memory have been observed on AP7 (Receiving). Reboots are performed as a fix.
• Severe connectivity issues with AP8 and AP9 caused a picking outage on Jan. 26, 2017. Upon further investigation, it seems the RADIUS component of the cluster glitched, causing the APs to behave erratically, connecting and disconnecting users. A staggered reboot of all Psion access points seems to have taken care of the problem.
• AP12 (Narc cage) has an older firmware than the other 3 APs in the cluster. This should probably be upgraded, but meh. -norwizzle (talk) 16:27, 27 January 2017 (PST)

To-do

• Roaming and roaming authentication
• Roaming stickiness
• Transmit power
• Presence of wireless b clients
