Details. What happens when you try to access the network? Can you
ping the router? Other hosts on the lan? Other hosts on the
internet? By name? By IP?

Actually, when I use firefox to access a website, it sometimes succeeds, but the speed is very very slow. It'll take about 5~10 minutes to open a Google main page. Sometimes it fails to open any pages.
I can ping the router. I can even access the route via the web admin interface of the router. The speed looks good too. That's the most weird thing.
I have only one host in the lan -- my laptop. Maybe I should connect one more computer for testing.
I tried to ping a website by name, it seems reachable. As I mentioned, sometimes web pages is reachable. The speed is intolerable.
Thanks again.

By speed, do you mean latency or data transfer time? What are the ping
times like (before and after suspend? How long does name resolution
take? Do protocols other than HTTP also suffer? What about other
browsers?

The network problem happened to me again today.
Here's your questions and my answers:
What happens when you try to access the network?
- When I try to open a web page, I just get no reply. Sometimes I get a reply after long time.
Can you ping the router? Other hosts on the lan? Other hosts on the internet? By name? By IP?
- I can ping the router:
$ ping 192.168.1.1
PING 192.168.1.1 (192.168.1.1) 56(84) bytes of data.

rtt min/avg/max/mdev = 1.057/17.102/64.149/27.166 ms
$
I can ping other hosts on the lan:
$ ping 192.168.1.11
PING 192.168.1.11 (192.168.1.11) 56(84) bytes of data.

I can ping other hosts on the internet:
$ ping www.debian.org
PING www.debian.org (194.109.137.218) 56(84) bytes of data.

rtt min/avg/max/mdev = 54.227/57.232/60.585/2.627 ms
$
By speed, do you mean latency or data transfer time?
- I don't know. When I access a web page, it is finished after long time. Sometimes it just fails.
What are the ping times like (before and after suspend?)
- Pinging seems ok even when internet is inaccessable.
How long does name resolution take?
- Name resolution seems ok.
Do protocols other than HTTP also suffer? What about other browsers?
- Other browsers such as Epiphany and w3m don't work either.
And also, when this happened, I plugged the wire and tried the wired network, it failed too.
Thank you very much.
Best Regards,
Forrest

Do you have any other machines on the network that you can test? What
about another OS on the machine? We need to figure out if there is a
misconfiguration on your machine or upstream.

You might try it to see if the problem is linux specific. You might
also consider my suggestion about other network protocols.

I see that your email seems to be originating from 10.78.135.20
What kind of connection (NAT ? IPv4 / IPv6 ?) does your ISP provides ?
(hint: Does your ISP provide address like 10.x.y.z ? you can usually get
this information on the router's status page).

Can you open webpages from your ISP ?
Can you try to open the following image when you have the problem
http://www.google.com/intl/en/images/icons/about_gafyd.gif
(Don't try to open it before you have the problem, to make sure your
browser don't cache it)
=> It's a small image (612 bytes) which is small enough so it's doesn't
get fragmented (MTU problems).

i turned IPv6 off both in /etc/modprobe.d/aliases and in firefox.
i never tried, i'll try next time
i guess that it might be the router's problem, since i can access the lan, am i right?

Re: cannot connect to the internet after resume
Maybe you need to unload the module for the network card before suspending and reload after suspending? Have a look and see if you have a /etc/default/acpi-support file and there should a line in there to list modules to unload/load during suspend/resume.
