Re: hp pavilion dm4

Hi:

 

What model wireless card do you have installed in your notebook?

 

if you don't know, you can find it listed under network adapters in the device manager.

 

What operating system are you running?  Perhaps a network card driver update will help.

Re: hp pavilion dm4

Let's see, under Network Adapters I have listed: Atheros AR 8151 PCI-E Gigabit Ethernet Controller (NDIS 6.20), 

Intel (R) Wifi Link 1000 BGN, Microsoft Virtual Wifi Miniport Adapter, Microsoft Virtual Wifi Miniport Adapter #2. I'm running Windows 7 Home Premium.

Re: hp pavilion dm4

Hi:

 

See if the latest Intel driver (for the WifiLink 1000) helps.

 

The notebook specs state you have W7 64 bit...You will want the second file download listed (driver only).

Thanks. I did that and restarted, but it hasn't made any difference. Oh dear...

Re: hp pavilion dm4

Hi:

 

Sorry that didn't work.

 

Does the notebook just do this at your house or everywhere (if you ever take it out)?

 

Sometimes I find that changing the router's broadcast channel helps with connections on some wireless cards.

 

You may want to try changing the router's broadcast channel to 1 or 11 to see if that makes a difference. Sometimes there is interference from other routers in the neighborhood all broadcasting on the same channel.

 

You will need to visit your router manufacturer's website to see how to access the router's configuration menu to change the wireless broadcast channel.

 

Also there are advanced settings for the network card in the device manager.

 

See this helpful guide below.

 

http://www.intel.com/support/wireless/wlan/sb/CS-025393.htm

 

Settings you should look for:

 

If it has a WMM setting, make sure it is set to Enabled.

 

If it has a Roaming Aggressiveness setting set that to Lowest.

 

Make sure the transmit power is set to HIghest.

Re: hp pavilion dm4

Hmm, I have never tried using my laptop anywhere else so I can't say if it would act differently. That would be a good idea to try though, thanks. 

However, I do know that other internet-connected devices don't have that problem. Other laptops and my smartphone never drop their wireless connection which is why I didn't think it could be my router. I am still going to try changing the broadcast channel anyway, thanks.

Re: hp pavilion dm4

You're very welcome.

 

Sometimes the channel change will work for all the devices.

 

It's like allergies. Some cards are fine with things the way they are, and some are very sensitive on certain settings.

 

Did you look for those advanced settings in the device manager?

 

Changing the roaming setting helps because that keeps the card from trying to look for a better signal.

Re: hp pavilion dm4

OK, then it is up to the channel change.

 

If that doesn't help trying a few different channels, then I'm afraid I don't have any other ideas you can try.

 

Best Regards,
