| NAME = 'network_WiFiTxRx' |
| PURPOSE = '''Check the Tx and Rx signal strength when associating with 802.11 |
| APs''' |
| CRITERIA = '''This test requires that a WiFI AP be set up as described in the |
| DOC section.''' |
| SUITE = 'hwqual' |
| TIME = 'SHORT' |
| TEST_CATEGORY = 'Functional' |
| TEST_CLASS = 'network' |
| TEST_TYPE = 'client' |
| |
| DOC = ''' |
| The AP used to develop the tests was a TRENDNET TEW-673GRU |
| |
| The described steps are annotated with the place they need |
| to be carried out: |
| |
| H - hardware (ie something phsyical) |
| P - root shell on your laptop/whatever |
| S - ordinary shell on your laptop/whatever |
| A - root shell on the AP |
| W - Web UI on the AP (in a browser on your machine) |
| |
| === first time, to flash OpenWRT onto a TRENDNET TEW-673GRU === |
| H Power the AP up |
| H Connect a patch cable from your laptop to a LAN port of the AP |
| S Get the OpenWRT image from the openwrt.org site |
| P dhclient your eth0 interface OR ifconfig eth0 192.168.10.2/24 up |
| W connect to 192.168.10.1, login as admin/admin |
| W Go to the firmware option in the menu |
| W Upload the image, allow to reboot |
| |
| === installing packages and initial setup on the AP === |
| P ifconfig eth0 192.168.1.2/24 up |
| P iptables -A POSTROUTING -t nat -s 192.168.1.0/24 -j MASQUERADE |
| P echo 1 >/proc/sys/net/ipv4/ip_forward |
| P telnet 192.168.1.1 |
| A passwd # set the root password to something here |
| P ssh root@192.168.1.1 - check you can get in with the new password! |
| A route add default gw 192.168.1.2 |
| A ssh USER@192.168.1.2 getent hosts downloads.openwrt.org >> /etc/hosts |
| A opkg update |
| A opkg install luci |
| A opkg install iwinfo |
