[Bug 556513] New: Poor WiFi connection
http://bugzilla.novell.com/show_bug.cgi?id=556513#c0 Summary: Poor WiFi connection Classification: openSUSE Product: openSUSE 11.2 Version: Final Platform: Other OS/Version: Other Status: NEW Severity: Major Priority: P5 - None Component: Network AssignedTo: bnc-team-screening@forge.provo.novell.com ReportedBy: jakub.rusinek@gmail.com QAContact: qa@suse.de Found By: --- Blocker: --- User-Agent: Opera/9.80 (X11; Linux i686; U; pl) Presto/2.2.15 Version/10.10 Since I have installed 11.2, I was constantly complaining about my ISP, but it seems that restarting "network" service makes my poor connection behave a bit better. What do I mean by poor connection? Somebody with another card, another driver on Factory (the later 11.2) met the same problems. http://old.nabble.com/WiFi-performance-on-11.2-td26149138.html I've got a RaLink 2561 802.11g based WLAN card and I'm using rt91pci driver with included ralink-firmware. Reproducible: Always Steps to Reproduce: 1. install fresh openSUSE 11.2 2. configure ifup/ifdown based connection (WPA2-PSK) 3. try using it. Actual Results: Dropping packets, jumpy speed (whiles of downloading at 120Kb/s and then again 0 - all and over again). Also, only the second or sometimes even the third request is completed. Overall it's very baaad. Expected Results: High transfer, stable connection. Ask for everything. Will remain restarting network service 'til you find the reason. Oh, about restarting network service. Take a look at command below and the output: $ sudo service network restart root's password: Shutting down network interfaces: vboxnet0 No configuration found for vboxnet0 Nevertheless the interface will be shut down. vboxnet0 done wlan0 device: RaLink RT2561/RT61 802.11g PCI wlan0 done Shutting down service network . . . . . . . . . done Hint: you may set mandatory devices in /etc/sysconfig/network/config Setting up network interfaces: vboxnet0 No configuration found for vboxnet0 vboxnet0 unused wlan0 device: RaLink RT2561/RT61 802.11g PCI wlan0 starting wpa_supplicant wlan0 Starting DHCP4 client. . wlan0 DHCP4 client NOT running wlan0 failed Setting up service network . . . . . . . . . . done -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

As I read in the Internet, it may be somehow corelated to power manager being default on. Some super hyper ultra new power saving technology is used and it probably breaks my connection. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

The DHCP is "dynamic host configuration protocol" which configures the network after the wifi card is connected to the AP. Most probably the DHCP fails because wpa_supplicant was not able to connect to the AP. Would it be possible to provide more information as described in the "Tracking down wireless problems" [1] ?

Q: My connection is dropped every few minutes A: Some access points tend to drop connections if the client is inactive for a specific amount of time. Sometimes this behavior can be changed in the access points configuration interface.
Definitely not my case. Before upgrade everything worked well. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

The interesting thing I noticed after filling with bug are: 1) thing from comment #1 (power saving on by default)
The power-saving causes trouble with some APs. You should better switch the "Power management" off [1]. You can check the status [2]. Try to switch NetworkManager off in Yast and connect with the ifup/ifdown method before you send debug logs [3].

After you set the power management off it remains switched off until the reboot. Right ? -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Each ifconfig/iwconfig setting is kept 'til reboot/shutdown etc. By "doing it" I really mean doing it: applying the setting on my own each day. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

From what I can tell you. Problem still remains though.
On earlier kernel I've got no problem. Something's broken in 2.6.3x. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
