39 | Setting up a W-IAP Dell Networking W-Series Instant 6.4.3.1-4.2.0.0 | User Guide
When you use a provisioning Wi-Fi network to connect to the Internet, all browser requests are directed to the
Instant UI. For example, if you enter example.com in the address field, you are directed to the Instant UI. You
can change the default login credentials after the first login.
Regulatory Domains
The IEEE 802.11/b/g/n Wi-Fi networks operate in the 2.4 GHz spectrum and IEEE 802.11a/n operates in the 5.0
GHz spectrum. The spectrum is divided into channels. The 2.4 GHz spectrum is divided into 14 overlapping,
staggered 20 MHz wireless carrier channels. These channels are spaced 5 MHz apart. The 5 GHz spectrum is
divided into more channels. The channels that can be used in a particular country differ based on the
regulations of that country.
The initial Wi-Fi setup requires you to specify the country code for the country in which the Instant operates.
This configuration sets the regulatory domain for the radio frequencies that the W-IAPs use. Within the
regulated transmission spectrum, a high-throughput 802.11ac, 802.11a, 802.11b/g, or 802.11n radio setting
can be configured. The available 20 MHz, 40 MHz, or 80MHz channels are dependent on the specified country
code.
You cannot change the country code for the W-IAPs in the restricted regulatory domains such as US or Japan
for most of the W-IAP models. For W-IAP-RW variants, you can select from the list of supported regulatory
domains. If the supported country code is not in the list, contact your Dell Support team to know if the
required country code is supported and obtain the software that supports the required country code.
Improper country code assignments can disrupt wireless transmissions. Most countries impose
penalties and sanctions on operators of wireless networks with devices set to improper country
codes.
To view the country code information, run the show country-codes command.
Specifying Country Code
This procedure is applicable only to the W-IAP-RW variants. Skip this step if you are installing W-IAP in the
United States and Japan.
The Country Code window is displayed for the W-IAP-RW variants when you log in to the W-IAP UI for the first
time. The Please Specify the Country Code drop-down list displays only the supported country codes. If the
W-IAP cluster consists of multiple AP platforms, the country codes supported by the master W-IAP is displayed
for all other APs in the cluster. Select a country code from the list and click OK. The W-IAP operates in the
selected country code domain.

You can also view the list of supported country codes for the W-IAP-RW variants using the show country-
codes command.
