Why is my laptop favoring the wireless connection over my LAN connection?
When my laptop comes out of sleep, I have to typically wait about 90-120 seconds before my network (wireless or NIC card) 'wakes up'.
During that time, I see my wireless connection with 'limited access' which means no access.
Eventually the wireless wakes up and connects, even if I have an ethernet cable plugged in and even when I am running on wall power.
In order to use the NIC, I have to disconnect from all my saved wireless profiles and then it is finally connected as a means of last resort.
I want to be able to wake immediately and connect directly to the NIC connection.
I have:
- Dell Latitude E5510 w/8GB RAM
- Windows 7 Ultimate
- Broadcom NetXTreme Gigabit Ethernet
- Intel Centrino Ultimate-N 6300 AGN
Try: Network and Sharing Center > Change Adapter Settings > Press and release Alt key to show the menu > Advanced > Advanced Settings
Move the LAN adaptor to the topmost position (This window says "Connections are accessed by network services in the order they are listed")
See my answer to this question.
You can set your laptop to "prefer" the ethernet conenction over the wireless. Technet has a quick overview:
The short answer is that Windows (Vista, 7, 2008, and I’m pretty sure XP and 2003 does as well) [or should do] this by default. The key here is the network interface metric. When you have more than one default gateway defined [...] then the internet bound packets go out the interface with the lowest metric.
[...] You can, of course, permanently alter your metrics by editing your TCP/IP settings on your network adapter’s advanced settings.
[...] You should know that Vista made a change to how we handle existing sockets – after plugging in, connections will not be switched over, you must re-establish the connection in order to make use of a wired connection. For example, if you’re downloading something from a website and realize that it would go faster by plugging in, you’d have to cancel and start over after plugging in. This is a change from XP and 2003.
For how to change these setting, have a look at this Microsoft KB article.
