2013-12-11Move Wifi/P2p service components under servicesVinit Deshapnde
Some methods need to be public, since frameworks/base complies before frameworks/base/services; and services takes build dependency on base. Similar issue exists with WifiEnterpriseConfig constants. Bug: 9907308 Change-Id: Ied0e3dee0b25c939067dbc66867a9814b3b3b68e
2013-11-20Remove unused imports from frameworks/base.John Spurlock

2013-09-19Remove STOPSHIP in WifiWatchdogStateMachineYuhao Zheng
There used to be some STOPSHIP code in WifiWatchdogStateMachine for debug purposes. We don't need them for the release. Bug: 10841961 Change-Id: I501d62e9891ace52317e6c1d399b877175099a3c

2012-10-16Handle null BSSIDIrfan Sheriff
The root cause of why bssid needs investigation, but for now, we can avoid crashing wifiwatchdog. When bssid is null, just treat it as a good link. Bug: 7357232 Change-Id: I080dfc990f3412646976cdc6ef75112ab093d326

2012-09-26First step towards cleaning up Global settings.Jeff Sharkey
Remove all @Deprecated @hide settings, and clean up any stragglers. Bug: 7232125 Change-Id: Ibf67093c728d4a28565129b923edb1701d3b2789
2012-08-27Captive portal handlingIrfan Sheriff
We now notify the user of a captive portal before switching to the network as default. This allows background applications to continue to work until the user confirms he wants to sign in to the captive portal. Also, moved out captive portal handling out of wifi as a seperate component. Change-Id: I7c7507481967e33a1afad0b4961688bd192f0d31
2012-08-15CTS test for WiFi watchdog - framework support.Yuhao Zheng
The new WiFi watchdog requires kernel/driver to export some packet loss counters. This CTS tests whether those counters are correctly exported. Change-Id: I41999676f8488e86f35f1f8214ce668f1a2b5638
2012-08-06WifiWatchdog changes for poor link detectionYuhao Zheng
- use packet loss (wlutil pktcnt) instead of frame loss, retune all parameters - use wpa_supplicant to get packet loss counters, instead of netd - handle BSSID roaming in all situations - improve flapping avoidance mechanism by setting different target RSSI - handle high packet loss in high RSSI (never seen in real testing) - add more comments on how to set all parameters Signed-off-by yuhaozheng@google.com Change-Id: I33429f063d8625a458be4791edd83a86d5a723df

2012-05-09Tone down poor connection avoidanceIrfan Sheriff
Until we figure out a way to compare a poor mobile network against and poor wifi network and then weighing in other factors, tone down wifi avoidance aggressiveness Bug: 6456541 Change-Id: Idc81e4d83f47c9870abbdb4359ddfeaffdcca838
2012-03-12Improve network avoidanceIrfan Sheriff
Adds a back-off based technique where the amount of time we wait before avoiding wi-fi is increased. This will reduce power consumption on devices that are experiencing high variance on wi-fi Change-Id: I40da03edfb5373ddb51056818ca0744dc26a5600
2012-03-08Enhancements for avoiding poor connection on wifiIrfan Sheriff
- Avoid flapping - Increase thresholds and monitor rssi more closely to detect consistently weak signal Change-Id: I6139a20b7306839b345146a72ce690020a2e00b8
2012-02-29Improve Wi-Fi hand-offIrfan Sheriff
When Wi-fi connects at L2 layer, the beacons reach and the device can maintain a connection to the access point, but the application connectivity can be flaky (due to bigger packet size exchange). We now use Watchdog to monitor the quality of the last hop on Wi-Fi using signal strength and ARP connectivity as indicators to decide if the link is good enough to switch to Wi-Fi as the uplink. ARP pings are useful for link validation but can still get through when the application traffic fails to go through and thus not best indicator real packet loss since they are tiny packets (28 bytes) and have much low chance of packet corruption than the regular data packets. Signal strength and ARP used together ends up working well in tests. The goal is to switch to Wi-Fi after validating ARP transfer and RSSI and then switching out of Wi-Fi when we hit a low signal strength threshold and waiting until the signal strength improves and validating ARP transfer.

2011-10-19Add a delay before walled garden testIrfan Sheriff
This allows a carrier app to authenticate before we notify the user. For future, we will provide an API that allows app to disable the walled garden check. Bug:5398921 Change-Id: Iff98ddaaa9fa38def4f43b1995f4b2c36f93a919

2011-09-23Fix watchdog to stop ping after wifi disconnectsIrfan Sheriff
- The pings are delayed async messages that were getting handled after a disconnect as well - Increase poll time to 200 ms, so we block on a receive for 1ms every 200ms for a sent packet Bug: 5361564 Change-Id: I1931a1c4146e78a87407d541d8c3934ff8232604

- Reduce DNS counts from 15 to 5. 15 was for debug. - Keep success scenario as atleast 1 being successful - Wait for a second to start checks (for some setups) - Use one bar as a start for doing periodic DNS checks - Do a DNS check every hour (instead of half hour) Bug: 5284337 Change-Id: Ie64d8cac48318a0c4c59f91ad21f8c6712b71338
2011-08-31Create new isNetworkSupported APIRobert Greenwalt
Useful for checking if on a wifi-only device. Similar to asking for NetworkInfo for a network type and checking for null, though here the intent is explicit. bug:5087537 Change-Id: Ia3ddd09b6b735b8b3ceb7a347891e015fd96b218
