My HP DV7t routinely looses its wireless connection, for no good reason, since I bought it a year ago. The remedy has been to reset my router, despite the fact that no other device in my house--even one other HP laptop and an HP printer--looses connection. But lately when I put the laptop to sleep--usually by closing the lid--the computer completely forgets what network is was connected to and so I have to manually reconnect each time. Even then, it takes a long, long time to connect and sometimes even says "it is taking longer than expected to connect to the network.". Glad it tells me what I already know! I have checked all of my settings in the Windows 7 "Network and Sharing Center" to ensure that my network is selected, that it is a home network, that "automatically connect"; is selected, and that all of my password data is correct. Still it refuses to automatically recognize the network and connect. I am at wits end with this and just cannot figure out why this is happening. I have not changed anything in my computer or router setup, so I am at a loss why the system forgets everything and has to be manually connected. The Wireless module in my computer is an Intel WiFi Link 1000 BGN and all the drivers are up to date.
Solved! Go to Solution.

Perhaps a driver update for the wireless card will help.
I don't know what bit version of W7 your notebook came with because there are no product specs listed for it.
32 bit is the first download listed (driver only).
64 bit is the second download listed (driver only).

You might now want to tweaking some of the advanced settings for the card.
See this link below...
Make sure WMM is enabled.
Set the Roaming Aggressiveness to Lowest.
Go into your router's wireless configuration menu and see if changing the broadcast channel to 1 or 11 makes a difference.

None of the suggestions so far have worked, but I seem to have found a solution: Switching my router from WEP encryption to WPA2 seems to have solved the problem, at least for now. I have no idea why this works, but a bit of google searching seems to indicate that WEP wireless can be flaky with some cards and routers. If it quits working, I'll be sure to repost for a solution. Thanks to everyone for the assistance---it takes a village (so to speak).
UPDATE: After 24 hours, the connection via WPA2 is rock stable, with no dropped connections. It is also even speedier for download/upload. Hopefully this solution will work for others.
