Your solution I think
I think I have the solution to your problem. Sorry I was so late in getting it to you. I'm a linux guy and came across this issue after I recieved a laptop with win 7 for XMAS. Anyway all I did was a combo of what everyone on here already said.
Below is my 2 prong attack of network connection JUSTICE!
** first do the priorities thing for your wired netwrok connection.
Control Panel
View Network and status...
Change Network adapter settings
**Press ALT KEY (dumb idea microsoft. Press alt key? GUI user friendly
Advanced
Advanced Settings
From there, move your wired connection up using the green arrow of dumbness. (Unless you want wireless to take priority...in which ensure that is infront of wired)
NEXT, click ok
NOW, hit alt again
NOW HOLD CTRL key WITH finger. while holding ctrl key - click on wireless and then wired (order doesn't matter)
With BOTH connections highlighted click on advanced...AGAIN
This time go to Bridge connections. And bridge them.
This solution may or may not be seemless. This will also help fix a wired to wireless network visible device problem.
Hope this was the fix to your issue as it was mine.
Would you like to know more?
I have a wireless enabled Windows 7 laptop which connects to my home network
normally when the network cable is unplugged or via the cable when it is
plugged in from boot. If I plug the network cable once connected to the
wireless, to gain extra speed when copying files etc, the laptop continues
to use the wireless over the wired route.
On my XP machines it would switch seamlessly to the fastest.
Is this a new and undocumented feature of windows 7 or do I need to change a
setting to make it swap automatically?
Thanks for your help
