Can't connect to Cisco 1142AP, 3602AP, 2504 WLC, 4402 WLC. Able to connect to TWC cable modem and DSL modems wirelessly. Have tried changing settings in the Advanced tab for Broadcom 802.11abgn Wireless SDIO Adapter properties.
Any assistance would be greatly appreciated.
For Bandwidth Capability, have changed it to: 11a/b/g 20/40 MHz
Where can I change the settings for 802.11n?
Changed the 802.11n Preamble setting to Mixed Mode instead of Auto.
