12.04 WiFi issue on a particular access point
- by user71706
I have a WiFi access point that I connect to a PC to share its Internet connection with multiple machines, in a training environment.
All the machines with 11.04 connect to this access point with no problem, and can access any server on the Internet. These machines have an Intel Wireless -N 1030 BGN chipset (as reported by lspci).
Now, my problem is that I don't manage to connect 12.04 machines to this wireless network. The systems I tried do manage to connect (confirmed by Network Manager), but when I try to access a website like http://kernel.org, the browser shows "Connecting to kernel.org...", but displays a "The connection has timed out" error page.
Other symptoms:
Name resolution works (for example 'nslookup kernel.org') finds
kernel.org's IP address
'ping kernel.org' doesn't work
The same 12.04 machines have no problem at all with other wireless networks. So there is probably something weird in my access point (though the 11.04 machines are not impacted).
Would you have any suggestions for investigating this issue?
Thanks,
Michael.
