我无法使用新的无线 USB 适配器连接到互联网。虽然我可以通过 NetworkManager 查看我周围的所有无线网络，但它无法连接到任何一个。我使用的是 Linux Mint 10 RC。我已将 rt2500usb 驱动程序列入黑名单，因为它与 rt73usb 同时加载。
以下是 lsmod 的输出：

有人能帮我解决这个问题吗？
提前感谢并致以最诚挚的问候！
根据 outofstep 的建议，我从以下网址下载了 RT2501USB（RT73：RT2571W/RT2573/RT2671）固件http://www.ralinktech.com/en/04_support/support.php?sn=501并将文件 rt73.bin 复制到 /lib/firmware 拔下 USB 适配器，再次插入但无济于事。重新启动计算机也无济于事。但无论如何还是要谢谢你。
这是 dmesg | grep rt73 的输出

感谢 outofstep 和 hhlp 迄今为止的支持。

好吧，我终于建立了互联网连接。我解决问题的方法很荒谬：我将 USB 适配器插入其中一个后部USB 端口。插入前端总线时，无线网络被检测到，但我无法连接到任何网络，正如我的问题所述。此外，在启动时插入适配器似乎不起作用。启动后必须将其插入后置 USB 端口之一。这真是令人难以置信。
无论如何，虽然这可能看起来很有趣：将 TP-Link TL-WN321G USB 适配器插入后置 USB 端口之一而不是前端总线，使设备连接到无线网络。我无法判断固件更新对解决方案有何贡献。感谢大家的帮助。
