Configure the board connection as explained in Preparing T1023 board.2. Insert the Wi-Fi cards into PCIe slots 1 and 2.3. Connect an Ethernet cable that can support 2.5 Gbit/s (for example CAT6 cable) into the Aquantia PHY port. Ensurethe host PC Ethernet port also supports Aquantia PHY.4. Connect the serial cable from the host PC to the T1023 board and use a serial console, for example TeraTerm.5. Connect the 8 x RF cables with 8 attenuators (about 35~45 dB each) between the dual 11 AC card and the 2 STAs asshown in the following figure.6. Run the console commands as explained in Configure 802.11AC Wave2 Wi-Fi using command line interface.7. Bring up two STAs (one for each card) and connect them with the T1023 access point.Figure 5. AC + AC dual card topologyThe following figure shows how to use the 8 x RF cables connected to the dual 4x4 AC cards and to two 4x4 STAs. Connectthe attenuators. It also illustrates how one U.FL/IPEX to SMA converter cable and one SMA cable is connected to a singleantenna port.Enable 802.11ac Wave2 Wi-Fi card on T1023 boardT1023WLAN Wi-Fi Wave2 Access Point Router Getting Started Guide, Rev. 0, 09/20156 Freescale Semiconductor, Inc.
SMA Cable U.FL/IPEXConnectorFigure 6. T1023 board cables connected with the antennas6Troubleshoot 802.11ac Wave2 Wi-Fi connectionCheck the following instances to troubleshoot your wireless connection:1. Switch to multiple wireless channels.2. Configure the RSSI and MCS values using iwpriv athx txrx_fw_stats 3 command. Check if the RSSI value isin between 35 - 50 and the RSSIs for the RF chains should be balanced. To change the RSSI data number, you need toadjust attenuator value on each chain. For example, if you did not get good performance because the RSSI data numberis too high and you need to tune it down, you should add more attenuators on each chain. Similarly, if the badperformance is due to low RSSI, you can remove some attenuators. Check the MCS value (Modulation and CodingScheme); make sure most packets are sent through the largest MCS value.3. Use the following command to check if the STA is connected to the wireless card of the access point:wlanconfig ath0 list sta 4. If required, reboot the system to check performance.Troubleshoot 802.11ac Wave2 Wi-Fi connectionT1023WLAN Wi-Fi Wave2 Access Point Router Getting Started Guide, Rev. 0, 09/2015Freescale Semiconductor, Inc. 7
