Slow Internet Connection in 11.04

[Nicholas McCurdy]

Appears related to bug #761901

Current Kernel: Ubuntu 2.6.38-11.48-generic

Symptom: Contacting remote websites takes multiple minutes to load complete pages (even more if remotely-linked objects exist embedded in the given page). Issue applies regardless of which of the two installed browsers are employed (Firefox / Chrome). Online Speed Tests rate connection throughput at 25 MbU / 5 MbD. Doesn't appear to affect Local Network operations (SSH to clients -using winbind to discover IPs- is smooth).

All other Linux/Ubuntu installations on the Local Network are of type i386 and appear unaffected. Unfortunately, no additional AMD64 system to test against...

Attempted Solutions:
* Static DNS server address assignment to 8.8.8.8, 8.8.4.4 within Network-Manager (vs. DHCP assignment from ISP) + Non-effective remedy
* IPv6 has been disabled in both SYSCTL and Firefox. + Marginal to Non-effective remedy
   - Browsing Status Messages prior to IPv6 disable indicated: 10+ sec. hang on HOST LOOKUP and again on SENDING REQUEST
   - Browsing Status Messages following IPv6 disable indicate: 2-4 sec. hang on HOST LOOKUP and 10+ sec. hang on SENDING REQUEST
* All Routing / Connection Hardware has been reset and programmed values have been verified + Non-effective remedy

Nicholas McCurdy, thank you for reporting this and helping make Ubuntu better. This bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? Can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ .

If it remains an issue, could you run the following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux <replace-with-bug-number>

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.
