Hello Graham,

I've been following this bug for quite sometime, just out of curiosity.
However, many of the comment posts here look like common issues that may
or may not be related to this particular bug. Yours sounds similar. Oh,
but not really same as #205 (Venkatesha). His was not connecting at all
(dmesg suggests a possible Network Manager bug/confusion where it hops
between different APs of same SSID before a connection is finally
established), while yours at least seems to connect initially. I can't
find your attached dmesg (forgot to attach?).

I am actively involved in wifi troubleshooting at ubuntu forums, and
this kind of problem, where network (wifi or ethernet) seems to be
connected but browsing internet fails. I'm not yet sure about the exact
reason but it seems to be like some sort of issue with 'resolvconf'
package that is supposed to take care of DNS configuration. In many of
such issues, the connection works as soon as 'resolvconf' package is
removed or NM (IP, Subnet, Gateway, DNS, or atleast DNS) is manually
configured instead of leaving it to DHCP.

Not saying yours must be same, but it *sounds* like above, so the DNS
issue is worth checking. Just try to ping first your gateway
(AP/router), if successful, try pinging any internet address, for
example Google's DNS servers 8.8.8.8 and 8.8.4.4. If you get ping reply,
it is definitely a DNS issue.

As for the disconnection issue, I frequently need to set driver
parameters "fwlps=N" and "ips=N" with almost all realtek drivers these
days. I know these options are there to save power on wireless card,
thus disabling them may cause unnecessary power drain issue, but
disabling them with values "N" frequently seems to solve disconnection
issues.

Then there is another issue where the "Power Management" on wireless
kicks in automatically and above two options are either not available or
don't help. Common with Intel driver, but I think I have seen that with
one of the Realtek drivers as well (recently, but don't remember which
one). There are other ways to keep it turned off.

I'm posting this just because I think people posting here should be
aware that there are also some common issues out there that may be
solved by some other ways. For detailed steps on trying the above
possible fixes, just check out the "Networking & Wireless" section of
Ubuntu Forums. One may find a similar problem with a solution there. Of
course they can also post their own thread asking for help, with
reference to this bug if they have the same card.

Good Luck,
Varun
