Windows 7: wireless connection getting dropped intermittently with Win 7

wireless connection getting dropped intermittently with Win 7

Hello,

I am facing an issue where the wireless connectivity drops intermittently for my Win 7 Home Basic Notebook.
Within less then a minute the connection is resumed. Earlier I thought that it was an issue with my service provider.
But then I did not face this issue with my Win XP notebook. I mean, both the notebooks are connected and then the wireless connection of Win 7 drops for a minute and then reconnects. During the period when the connection drops, I can still see my SSID, and also checked that the Win XP was connected and I could access the internet.

What could be the root cause and the possible solutions for this issue?

It is really frustrating when the connection drops when I am downloading big files and I have to start all over.

Best Regards,

Prashant

I would first look for updated drivers for your wireless card. If that doesn't help look for firmware updates on your router/access point.

Almost always when this has happened for me, it was the result of an incompatibility between the wireless chip in the wireless router and the wireless chip in the device. I have a LG Blueray player, for example, that absolutely refuses to maintain a connection to an Apple Airport Extreme, but is happy as a lamb talking to a D-Link DIR655 -- which I had originally replaced because a Macbook Pro 13" was refusing to maintain a wireless connection to it. So now I'm running two wireless networks in my house, one on each router. SIIIIIGH! Standards. What a concept .

But of course, do make sure you have the latest wireless driver in the system and the latest firmware in the router. I'm just pointing out that it might take buying another wireless router thanks to incomplete or buggy wifi chip implementations that have interoperability problems.

The dual router arrangement is the most likely cause of this problem which is very typical when dual router networks are not configured correctly. This is why I always recommend that people use a dedicated access point rather than trying to configure another router as an access point.

You need to disable DHCP on one of those routers. I'd keep the DIR-655 as the DHCP server/gateway as it's a superior router compared to the Apple.

You may also need to change the default gateway of the Apple to fit into the subnet of the D-link router. The gateway for the DIR-655 is 192.168.0.1 so you should make the IP of the Apple 192.168.0.2 and turn off DHCP, you might even need to pull down the firewall on the Apple.

Uhm, no, I'm not the original poster, and my setup works just fine with no (zero) dropped connections, thank you. The Apple is the primary router because it handles IPv6 (which my ISP, Compost, *sort* of supports -- as in, I can ping -6 their IPv6 DNS server, but can't get beyond it to the IPv6 Internet as a whole) while the older D-Link does not. The D-Link is set up in pass-through mode with DHCP disabled, and is set up as a separate WiFi network with its own SSID since it is a Wireless G router rather than a Wireless N router and I don't want to connect to it with any device other than that LG Blu-Ray player.

The original post has only a single network and single router and his laptop keeps dropping connections. I was simply pointing out that last time I ran into that problem, it was an incompatibility between my router and the device I was attempting to attach to it, thus why I brought the D-Link out of retirement and re-configured it the way I re-configured it -- the LG had no trouble talking to the D-Link, but would not sustain a connection to the Apple, it kept dropping. No other device on my network has trouble talking to the Apple so undoubtedly it's a bug in the WiFi chip used in the LG, but that's how it works sometimes.
