Resurrecting as it's still not working out well in Vivid.
** Changed in: linux (Ubuntu)
Status: Invalid => Triaged
** 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, with no network load on either the router or the WiFi
chipset. The computer is ~4 feet away from a Verizon Jetpack MiFi 5510L
connected to a power source, with no obstructions between them. Other
clients (Ubuntu with different chipset, Windows) don't have this
problem.
With the router on battery only, Vivid live environment and mainline
4.0, situation has improved, but still get bursts of 2 packets with
300-450ms every 50-100 packets, with ~1% packet loss.
