Hi everybody,
since a couple of years I am a very happy user of Archlinux. I never had big problems or, at least, I always could solve them with the topics posted on the forum.
Since some days (maybe after an update), my wlan connection is became very slow. I have an old Realtek card (MA521) which was always connecting at 11Mbps
03:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8180L 802.11b MAC (rev 20)
But since a couple of days, the card is only able to connect at 1Mbps. Here you are the output of iwconfig wlan0

Here you are also the output of lsmod

Any ideas? Thanks very much for your help.

You want to set the rate to 54 Mb/s. You can do this adding IWCONFIG="rate 54M" to your network profile and then reconnecting.
