After suspend, Wi-Fi performance is poorer -- Asus Eee 1005HA

[Cullen Walsh]

Binary package hint: network-manager

Running Ubuntu 9.10 on an Asus Eee 1005HA.

When Ubuntu returns from a suspended state (definitely on suspend, not sure about hibernate) when it had previously been connected to a wireless network, wireless performance is considerately degraded. This is shown by Firefox failing to load highly available sites, such as http://www.google.com/ , and dropped packets when pinging a known host. This is unaffected by if it were connected to the same or a different access point when resumed. The only solution is to restart network manager using "sudo /etc/init.d/network-manager"

I have also noticed this in both 9.10 and 10.04 pre release that I'm currently using.

Is this problem still present in Ubuntu 12.04?

If so... what's your wireless hardware and what driver is driving it?

Can you reproduce the problem and then run "apport-collect 552749"?

[Thomas Hood (jdthood)]

What is the output of "iwlist wlan0 rate" before and after performance gets degraded?
