Hello. First-time Qubes user, somewhat new to Linux. I'm not able to connect to the network over Ethernet. In the system tray is a red network icon with an x. If I click it and select "Wired connection", the icon changes to two circling red dots (i.e. a "wait" icon). Occasionally a message pops up saying "The network connection has been disconnected." Eventually it gives up and goes back to the red network icon.
I'm able to connect to the network using the same computer with a different OS. I tried replacing my cat-5 cable, but no luck. The cat-5 cable connects to a wifi repeater, if that makes any difference. The wifi repeater is programmed with the wifi network information; when I connect a computer to it, it's typically treated like any other wired connection. I'm using wifi, so I don't have a modem I can connect to. I do have a wifi USB card, but I don't know how to make Qubes use that (I know how to attach USB storage devices, but not this). I'm running Qubes from a USB stick, if that makes any difference. I'm on the same computer I used to install it. I have an old Biostar TPower X79 mainboard. When I look at the properties for sys-net, it shows the following device attached: 0b:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd.

Thank you very much for any suggestions, and if I can provide any other info just let me know. -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
