Wireless Signal on Mac Strong - Wireless Signal on Windows 7 Terrible?

So here is the problem. I went back on my Mac OS X Lion, the wireless signal strength is full, maximum, no connection issue.

So I restarted my computer onto my Bootcamp Windows 7 (x64) with the latest Bootcamp 3.3 Drivers sets. The wireless signal was initially 4 out of 5 bars and after a second, it went to 1 bar! I have no idea what happened or why or if there is any simple solution.

I am dying to get some proper answers (I did google the solution and all but changing the power out-put to maximum performance did not help!).

Any help, suggestions or anything would be greatly appreciated. I apologize for my terrible English. (lol) :P

You've done well with the boot camp drivers now check that you have the latest Windows drivers for your wireless card. Sometimes with these updates the driver software for various items is left out. Then again it could be one of those teething problems with Lion.

I have the latest Windows Drivers for my wireless card. Apparently, this is the only place that does not work. There were some solutions saying that this can be fixed through using Bootcamp 3.0 32 bits Windows 7 drivers. I am inclined to say that it won't work although I have not tried it yet. Do you think that it could be the solution?

I had exactly the same issue on a 2013 15" Macbook Pro Retina with Windows 7 64-Bit Professional on Bootcamp 5.0.5033. Perfect wireless on OSX and an excellent signal showing on Windows but, once connected, it dropped to poor unless I was right beside and adjacent to the router. Even at that, if I the turned the Macbook 90 degrees, the signal went from 4 bars to 1.

Bootcamp had installed driver version 5.106.199.1 for the Broadcom network adaptor in the Macbook. I manually installed an older driver (version 5.100.57.8). This would not connect for me so I undid it by rolling the driver back to the originally installed 5.106.199.1.

My wifi router is a Netopia 2247-62 and I looked up my internet service provider's home page for the router. It said that the security was set at WPA Version 1 & 2.

I checked the Windows 7 security setting for my internet connection - it was set at WPA-Personal. I changed it to WPA2-Personal and immediately got excellent signal strength and range.

So check that the security setting on Windows 7 matches that of your router. If you do not know how to access your router details, you will need to research it or contact your service provider.

To check or change the network security in Windows 7 - click on the wifi symbol on the task bar, click on Open Network and Sharing Center, click on Manage Wireless Networks, click on your network to highlight it, then right click, Properties, select Security tab and select the Security type to match that of your router. You will then have to re-enter your network security key.

Alternatively if you cannot access the router information, you should check for inconsistencies between the network settings (the security setting in particular) in Mac OSX and in Windows. The nature of this problem is such that the Mac OSX wireless settings must be good and should be duplicated on the Windows wireless settings. To view the Mac OSX wireless security settings, click on the wifi symbol at the top of the screen, click on Open Network Preferences, click on Advanced and then on the wifi tab.

On my Mac in OSX , security was reported as WPA/WPA2 Personal. My Windows 7 settings on the Mac had by default on installation set security to WPA Personal giving poor connectivity. Changing the Windows 7 settings to WPA 2 Personal as described above gave excellent connectivity.

The MacBook Pro's wireless adaptor's hardware is the:

I searched and searched and couldn't exactly find the driver itself for Windows 7 x64 bit. So I guess we'll just have to live with what we've got.

Thanks!
