[Bug 1445840] Re: 10ec:8176 10-20% packet loss on 802.11n network

  Thread Previous • Date Previous • • Thread Next 
** Description changed:

  With a Asus PCE-N10 PCI-E Adapter Wireless N I have 10-20% packet loss
  on a 802.11n 2.4GHz network, 2-3200ms latency pinging just the gateway
  192.168.1.1. The computer is ~4 feet away from a Verizon Jetpack MiFi
  5510L, with no obstructions between them. Other clients (Ubuntu with
  different chipset, Windows) don't have this problem. The mainline 4.0
  kernel seemed to work much better, so I'll go forward on the assumption
  this is fixed.
  
- 3.19.0-15.15 doesn't have working keyboard or mouse, and networking
- didn't automatically kick in at login screen.
+ 3.19.0-15.15 doesn't have working keyboard or mouse, and networking didn't automatically kick in at login screen.
+ 4.0-rc3 has similar improvement to 4.0.
