I got a RTL8192CE - what should I look for, when using net80211? Cheers Marcus signature.asc Description: PGP signature

It's zero with your patch; I do not have values from before at hand right now, but can provide them later on, should they be of interest. Cheers Marcus signature.asc Description: PGP signature
Bad rtwn(0) performance with RTL8188CE on -CURRENT after r302035
Hi, thanks to previous efforts, the rtwn(0) connection for my RTL8188CE wireless card is far more stable. It seems to come at the price of relatively bad performance, though. After r302035 from avos@, I can't get more than 500 kbit/s downstream from anywhere. Let me know, what information is necessary to isolate and correct that issue. I'll gladly test it. :-) Cheers Marcus signature.asc Description: PGP signature

rtwn connection stops working on CURRENT
Hi, I'm running into a somewhat weird issue with the rtwn driver on CURRENT. It usually works for a couple of minutes (if there's not too much of troughput happening) before the downstream and upstream rates just "dry up" and the interface stops working. It happens faster, if there are multiple connections open at the same time, e.g. having a browser open or fetching mail and doing a portsnap update. Once the connection stopped working, dhclient will report the following: Jun 11 12:22:22 athena dhclient[474]: send_packet: no buffer space available Jun 11 12:24:08 athena last message repeated 4 times ... wpa_supplicant reports: Jun 11 12:22:20 athena wpa_supplicant[335]: wlan0: CTRL-EVENT-DISCONNECTED bssid=... reason=3 locally_generated=1 Jun 11 12:22:20 athena wpa_supplicant[335]: wlan0: WPA: 4-Way Handshake failed - pre-shared key may be incorrect Jun 11 12:22:20 athena wpa_supplicant[335]: wlan0: CTRL-EVENT-SSID-TEMP-DISABLED id=0 ssid="..." auth_failures=8 duration=100 reason=WRONG_KEY Jun 11 12:22:20 athena wpa_supplicant[335]: wlan0: CTRL-EVENT-SSID-TEMP-DISABLED id=0 ssid="..." auth_failures=9 duration=152 reason=CONN_FAILED pciconf -lv: rtwn0@pci0:3:0:0: class=0x028000 card=0x819510ec chip=0x817610ec rev=0x01 hdr=0x00 vendor = 'Realtek Semiconductor Co., Ltd.' device = 'RTL8188CE 802.11b/g/n WiFi Adapter' class = network An pointers on tracking this issue down and getting it fixed are highly appreciated.

rtwn(0) panics with RTL8188CE
Dear all, thankfully -CURRENT supports the RTL8188CE wifi chipset via rtwn(0) on the Thinkpad X230. Unfortunately the connection to the AP drops nine times out of ten after transmitting a few kb. Trying to reconnect via service netif restart will cause a panic: panic: Memory modified after free 0xf80005c50800(2048) val=19 @ 0xf80005c50800 cpuid = 0 KDB: stack backtrace: db_trace_self_wrapper() at db_trace_self_wrapper+0x2b/frame 0xfe04552ae540 vpanic() at vpanic+0x186/frame 0xfe04552ae5c0 panic() at panic+0x43/frame 0xfe04552ae620 trash_ctor() at trash_ctor+0x4b/frame 0xfe04552ae630 mb_ctor_pack() at mb_ctor_pack+0x3c/frame 0xfe04552ae670 uma_zalloc_arg() at uma_zalloc_arg+0x504/frame 0xfe04552ae6d0 m_getm2() at m_getm2+0x12d/frame 0xfe04552ae740 m_uiotombuf() at m_uiotombuf+0x62/frame 0xfe04552ae790 sosend_generic() at sosend_generic+0x356/frame 0xfe04552ae850 kern_sendit() at kern_sendit+0x244/frame 0xfe04552ae900 sendit() at sendit+0x126/frame 0xfe04552ae950 sys_sendto() at sys_sendto+0x4d/frame 0xfe04552ae9a0 amd64_syscall() at amd64_syscall+0x2db/frame 0xfe04552aeab0 Xfast_syscall() at Xfast_syscall+0xfb/frame 0xfe04552aeab0 --- syscall (133, FreeBSD ELF64, sys_sendto), rip = 0x8015aac6a, rsp = 0x7fffd6a8, rbp = 0 x7fffe3b0 --- pciconf -lv: [...] rtwn0@pci0:3:0:0: class=0x028000 card=0x819510ec chip=0x817610ec rev=0x01 hdr=0x00 vendor = 'Realtek Semiconductor Co., Ltd.' device = 'RTL8188CE 802.11b/g/n WiFi Adapter' class = network Any help on getting this fixed is highly appreciated.
