我在设置一个Hama无线USB手柄54连接到我的老电脑有困难。这就是发生的事情:
我确实使用过Hama无线手柄,在与Win XP相同的计算机上没有任何问题。
这就是我试图修复或诊断问题的地方:
echo "blacklist rt2500usb" | sudo tee /etc/modprobe.d/blacklist-Hama.confecho "blacklist rt2500usb" >> /etc/modprobe.d/blacklist.confsudo sed -i "s/wifi.powersave = 3/wifi.powersave = 2/g" /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf- There is a diagnostic script mentioned, but I couldn’t fully figure it out. This is the output I got (with the connection lost):wpa_supplicant v2.4
random: Trying to read entropy from /dev/random
Successfully initialized wpa_supplicant
Initializing interface 'wlx000e2efc752f' conf 'wpa_supplicant.tmp' driver 'wext' ctrl_interface 'N/A' bridge 'N/A'

Failed to add interface wlx000e2efc752f
wlx000e2efc752f: Cancelling scan request
wlx000e2efc752f: Cancelling authentication timeout- I compared the outputs. These are (in my opinion) the main differences:
1. With connection:wlx<IF from MAC [IF2]> IEEE 802.11 ESSID:"XXX-20-15"
Mode:Managed Frequency:2.437 GHz Access Point: <MAC 'XXX-20-15' [AC1]>
Bit Rate=54 Mb/s Tx-Power=20 dBm
Link Quality=36/70 Signal level=-74 dBm wlx<IF from MAC [IF2]> IEEE 802.11 ESSID:"XXX-20-15"
Mode:Managed Frequency:2.437 GHz Access Point: <MAC 'XXX-20-15' [AN1]>
Bit Rate=36 Mb/s Tx-Power=20 dBm
Link Quality=40/70 Signal level=-70 dBm
...
wlx<IF from MAC [IF2]> Interface doesn't support scanning : Device or resource busy- I have also created a script output after I ran the diagnostic script mentioned above earlier ([https://translate.google.de/translate?sl=auto&tl=en&u=https%3A%2F%2Fforum.ubuntuusers.de%2Ftopic%2Fherstellung-der-wlan-verbindung-dauert-sehr-la%2F%23post-4040812](https://translate.google.de/translate?sl=auto&tl=en&u=https%3A%2F%2Fforum.ubuntuusers.de%2Ftopic%2Fherstellung-der-wlan-verbindung-dauert-sehr-la%2F%23post-4040812))

2. Maybe it helps investigating as well所有这些都说,我会感谢一些帮助,使哈马无线手柄工作。

我几乎不好意思回答我自己的问题。然而,这个问题是偶然解决的。
意外的是电脑根本不想再启动了。最后,我重新启动并运行了它,但是在BIOS加载时就停了下来。它抱怨时间过快。因为我得到了这台电脑二手,实际上我从来没有查看过BIOS。
不过,我有两种选择--输入BIOS设置的F1或将BIOS重置为标准的F2。所以,我采用了简单的方式(F2),因为我不需要任何特殊的BIOS设置。
对我的喜悦来说,电脑启动得很好。我重新安装了所有的设备.惊喜..。无线网络一直在运行、运行和运行。到目前为止还没有断线。我是个快乐的露营者。
我不得不假设某些BIOS设置实际上导致USB端口安全供电和关闭什么的。我不知道,我不明白,现在我也不在乎。我只是很享受。
