#21637: Brcm6358 WiFi intermittent in trunk
-----------------------+------------------------
Reporter: anonymous | Owner: developers
Type: defect | Status: new
Priority: normal | Milestone:
Component: packages | Version: Trunk
Keywords: |
-----------------------+------------------------
I arrived home, sat down and switched on WiFi on my tablet. I got 2 pages
up on Chrome before wifi was lost. I never left my seat and the router is
4m away.
Any idea on how to get more debugging info or how to investigate further?
From my HG556a running Trunk r48277 syslog:
