Comment 65 for bug 212497

Just want to add my observation regarding this issue, hopefully it may help the ubuntu team to find narrow down the caused and find the fix.

I am basically have 3 machines at my home: 1 Laptop (Dell, running Vista homepremium, wireless connection to the router), and 2 Desktops (one with Ubuntu Hardy 2.6.24-16 generic and the other dual boot XP/Feisty; both machines wired connection to the router DLink DSL 604T ADSL-Router).

The computer which has Hardy installed is similar to what Kevin has (CPU: Intel E2180 M/B: Gigabyte GA-G31M-S2L Lan: Realtek RTL 8111C chip (on-board).

I noticed that if I turn on the Hardy machine while the laptop is off/or in sleeping mode, internet connection is always successful (from Hardy machine).

However, if hardy machine is turn-on while the laptop is already on (so it turns-on after the Laptop), connection will never successful (failed).

There is no affect from the other desktop. i.e. internet connection from Hardy machine will always successful even if the XP/Feisty was turn-on first.

If I use the 100/10 LAN card for the Hardy machine (so disable the on-board gigabit LAN), it always be able to establish the connection even if it is turn-on after/while the laptop is already on

So, in my case the unsuccesfull connection is due to some other computer with wireless connection has preceeded a Hardy machine using gigabit lan. I don't know if the other have particulary observed this situation too when they say sometimes work and sometimes doesnt.

Cheers,
Bink
