Hello, my computer is "doubly" connected to my router; it is both wired and wireless (802.11n). The reason I do this is because sometimes the signal drops on the wireless and I need to connect wired until I fix the problem. I used to disable the wired driver whenever I was connected wireless, but I was wondering if it's OK to leave it always enabled and be doubly conncted. Furthermore, I want to know which connection is actually being used when both are connected. The two connections have different IPs and I'm using port forwarding so this is important. Finally, are there any advantage(s) or disadvantage(s) in maintaining two active connections at the same time to the same router, from the same computer? Thanks.

If you have modern equipment it should select the fastest. It could also fail. (there are a lot of rules, some are old and depend on the setup) You can't actually use both (not by default) Personally, I only use wireless when no wired solution exists. From your standpoint it is one more thing to fool with. Leave it on wired and disable the wireless both in the XP and the modem/router. I read it wrong and answer it wrong too. So get off my case you peanut.

I have to agree. If you have both available, best to go with the wired solution. It's more reliable and faster.

but is the OS going to select the wired solution automatically? PS: it is not faster at my home. 802.11n is faster, since my home is badly wired and the cable from my room to the router is so long 100mbps is not possible.

The OS will use both. When is up to the application and how it detects protocals and allocates usage. It typically can't hurt anything but sometimes strange things can happen. You could bridge the two connections if you want to share both of them, this should allow decent fallover if one loses connection, but again it's better to stick with one, and discover why your wireless loses connection instead of using both all the time.
