Created attachment 381297 [details] First tcpdump data capture Description of problem: Using FireFox and several open tabs the wireless performance will degrade and eventually stop yielding "server not found" errors in the open tab windows. Initially, I believed this to be a router problem since I installed a WRT160N which is known to be a lemon. However, I have upgraded to v3 build 4 and performance improved. Additionally, the Windows laptop I have does not seem to experience the problem nearly as much as FE-12. Moreover, I have recently purchased an iPod and it connects up seamlessly with this router. In fact, while the FireFox on FE-12 is "hanging" on wireless throughput the iPod going through the same router performs fine. Finally, when performing the same test with FireFox on FE-12 with multiple tabs using an ethernet cable to the router rather than a wireless connection the system performs as expected. Having said all of this, FireFox on FE-12 using wireless connections to other routers does not demonstrate the same poor performance when going to a WRT54G router. Version-Release number of selected component (if applicable): This prolbem has persisted since FE-11 How reproducible: everytime Steps to Reproduce: 1.open FireFox 2.open several tabs and open web pages 3.observe performance Actual results: Connectivity to the wireless device shows 3/4 bars but no data throughput Expected results: data throughput via wireless connection maintains good performance Additional info: I have attached two tcpdump captures. The first started just after connecting wirelessly to the router up and to when the tabs windows display server not found error. At this point, I disconnected and then reconnected to the router wirelessly and started surfing multiple tabs again. This tcp data is captured in the second file.

Do pings to the default router function normally? Are there any interesting messages from your wifi device in 'dmesg' ?
here is one message that might provide a clue to the problem. wlan0: no probe response from AP 00:18:4d:96:41:4e - disassociating wlan0: deauthenticated (Reason: 7) wlan0: authenticate with AP 00:18:4d:96:41:4e wlan0: authenticated wlan0: associate with AP 00:18:4d:96:41:4e wlan0: RX ReassocResp from 00:18:4d:96:41:4e (capab=0x431 status=0 aid=8) wlan0: associated I have been using a direct cable from this router and it works just fine. It's only the wireless that is a problem. When using ping or arp the repsonses can be many seconds or longer. When using tcpdump -i wlan0 there are many "whois" queries going out. It's like the wlan0 device is losing the Mac addresses to IP mapping. Other computers/IP devices work OK with this wireless router.
I have retested the wireless ethernet connection on my laptop and found that it now performs as expected. My suspicion is that the previous software was losing the IP address of the router, and therefore, making multiple lookups at each network transaction. kernel-2.6.31.12-174.2.22.fc12.x86_64 kernel-2.6.32.9-70.fc12.x86_64 kernel-2.6.32.9-67.fc12.x86_64 I believe this bug can be closed.
This message is a reminder that Fedora 12 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 12. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '12'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 12's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 12 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
The performance using multiple open tabs when upgrading to FE-14 and FF 3.6.12 was not observed. Please close.
Fedora 12 changed to end-of-life (EOL) status on 2010-12-02. Fedora 12 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed.
