Windows 7 refuses to make a stable connection

  robzwolf 14:42 29 Nov 10

I just bought myself a nice new Medion E4120 D on Saturday. It has a wireless-n chip (which is also wireless b/g compatible). My router is not wireless-n enabled. My new PC often refuses to connect to the router. When it manages to connect, it will often drop the connection again. I never have this problem with my netbook or my old desktop (which used an external wireless reciever (g)). It is really annoying as I cannot download anything from the internet or install programs properly because they need to activate/register online. I've changed the wireless chip's settings to IEEE 802.11b/g (it used to be IEEE 802.11b/g/n). According to Windows, I have a 'Realtek RTL8191SU Wireless LAN 802.11n USB 2.0 Network Adapter'

I only bought this PC on Saturday (Aldi offer me a 60-day money back guarantee and the PC has a length 3-year warranty) so should I take it back?

After trying the troubleshooters and diagnosers there is still a problem.

Any help please?

Also, not sure if I should post this here but whilst I was browsing through the adapter's configuration window (Control Panel > Network and Internet > Network Connections > Wireless Network Connection > Properties > Configure) in the advanced tab there are two options I want to know about:

802.11d - I have an option for Enable or Disable (it's disabled by default), what is it? another type of wireless?
Beacon Interval - Numeric Value (100 by default), what's this?

I also change the IEEE 802.11b/g/n to IEEE 802.11b/g (which I said earlier) in this window.

also I have another icon in Control Panel> Network and Internet > Network Connections

there is Local Area Connection (obviously) Wireless Network Connection (my main wireless one) and then a weird Wireless Network Connection 2. What's the last one? Instead of the Realtek one, it is called 'Microsoft Virtual WiFi Miniport Adapter'. What's this for?

If the driver version is lower than 1086.23.0607.2010 then click here and download and update the wireless driver to this version .

I had a problem with a laptop that had problems connecting to my hub although a PC in the same room as the hub connected every time.
After much head scratching changing the wireless channel from the default 6 to channel 11 rectified the problem.
