On Friday 17 January (Saturday 18th, Australian time) Cisco announced via a "Field Notice" that WiFi devices may have trouble connecting. They describe the problem as, "A newly installed Access Point (AP) fails to join its controller or it joins the controller, but is only able to bring up one radio due to a manufacturing mismatch between the AP's domain and the radio's domain.
"On a Mobility Express (ME) AP, the 2.4GHz radio will come up in Day 0 mode; however, after you configure the correct country code, the internal AP might fail to rejoin or might bring up only one radio."
The document then listed 87 different models that are affected, noting that "In the manufacturing process, the radios for some APs were set for regulatory domains which do not match the Product ID (PID)."
Buried in the fine print is the observation that, "If your Ship to Address is in the following countries, please expect delays of up to 3 months depending on importation regulations: Argentina, Brazil, Columbia, Mexico, Venezuela, India, All countries in Asia (i.e. Singapore, Malaysia, Hong Kong, China, Vietnam, Korea, Thailand, Philippines), and all non-EU countries (ie: UAE, Russia, Turkey)."
It is not clear if this list of countries is exhaustive, but three months is rather a long time to wait for a replacement unit.
iTWire has submitted a number of questions to Cisco (including an estimate of the number of affected units and how widespread the problem is in Australia / New Zealand).
This story will be updated when a response is received.
Update: 5:40pm. iTWire has received the following response from Cisco:
There are seven models which are affected in Australia. These are:
There is a total of 207 APs that have been affected across Australia. The majority of the units have already been RMA'd (Return Merchandise Authorisation) via our CX Centre (formerly TAC). These are also in general supply in distributor stock or shipping within 28 days.
