Windows7 WiFi download speed extremely slow

Hi. I installed Windows7 RC1 on a partition of my HP notebook (Vista licensed). The internet navigation with the internal WiFi interface is fast, but when I start a download, the data speed quickly decreases to near 100 Bytes / second ! If at the same time I use another netbook attached on my personal WiFi network (this one based on XP SP3), the same download runs at fast speed. May be there is some parameter to change in order to obtain full download speed on Windows 7 ? Any help will be appreciated, thanks.

Hi E.Ficara,

Thanks for posting to the Getting Ready for Windows 7 community forum.

Since the issue occurs during download, is there a third party virus scanner running on this system?  Is there a definition that might be activated when downloading from the internet?

What you may do to troubleshoot this issue is boot your system in a clean boot state, remember this will make your system vulnerable so use this limitedly to troubleshoot and be certain of what you choose to download from the internet when troubleshooting this issue.

To boot in a Clean Boot state

How-to run Windows in Selective Startup (Clean Boot)…

1.     Click Start, click Control Panel, click System and Maintenance, click Administrative Tools, and then double-click System Configuration.

2.     Click Continue, or provide Administrator credentials if prompted.

3.     Click the General tab, and click Selective startup.

4.     Under Selective startup uncheck Load startup items.

5.     Click the Services tab, check the Hide all Microsoft services box, and then click Disable all.

6.     Click the Apply, then OK, and then Restart.


After the system is restarted - Enable the services one by one and running a download test between each service to determinewhat is conflicting with the download speed (Clean Boot)…

1.     Click Start, click Control Panel, click System and Maintenance, click Administrative Tools, and then double-click System Configuration.

2.     Click Continue, or provide Administrator credentials if prompted.

3.     Click the Services tab, check the Hide all Microsoft services box, and then click Enable on one or half of the services listed.

4.     Click the Apply, then OK, and then Restart.
5.  Try your download again.  If the speed has decreased then one of the services started has caused the error.  Try disabling those services one by one until the service is identified.



After identifying the service or startup issue, place your system back into a normal state (Clean Boot)…

1.     Click Start, click Control Panel, click System and Maintenance, click Administrative Tools, and then double-click System Configuration.

2.     Click Continue, or provide Administrator credentials if prompted.

3.     Click the General tab, and click Selective startup.

4.     Under Selective startup check Load startup items.

5.     Click the Services tab, check the Hide all Microsoft services box, and then  Enable all the services.

6.     Click the Apply, then OK, and then Restart.
