I have a Dell XPS m1530 with wireless AGN and ethernet 10/100.
Recently my laptop keeps cutting out from the internet and it takes a hard restart to try and revive the connection. I have done everything i can (disable network adaptors and enable them again, repair it, manually enter dns number, ipconfig/renew but nothing seems to work).
There is nothing wrong with my modem/router as it works fine on all other computers that i have. The cables are fine too.
Do you have any solutions to this problem, or do i just have a defective ethernet controller and wireless?

Might be a problem with your IP stack, but I'm not really an expert on the subject.

Cards do fail. I had to replace my built in last week. But it was a cheap raylink card that had problems from day one. If your SSID is hidden un-hide it it may help.

-
it should be an option in your basic router setting- you can set it to broadcast or turn it off(hide). It's hat broadcasts
your router name, like dlink--linksys--or whatever you named it.............also, did you check the power settings on your wifi card to make sure it's not being turned off? -
the internet even cuts out when the ethernet is plugged in.
There shouldn't be anything wrong with the router as all my other computers and laptops work fine. -
What OS you have?
-
i am running vista on my XPS. vista and xp run fine with my router on my other computers
This is what it says when i try to diagnose and repair the connection
-
Can you connect this laptop using ethernet?
-
I can connect some times. Its just that it cuts out after about 10 mins of browsing. Sometimes you just can't connect at all.
Also, wireless hardly ever connects to the router. It says that there is limited connectivity when i am standing about 1m away from it. -
What type of broadband connection you have, dsl, cable, fiber, dial up...?
-
i have dsl ADSL2+ up to 21mbps
-
On that point, you might check to see if the laptop is trying to use IPv6 instead of IPv4. The router may not be able to properly digest IPv6; or else there may be the aforementioned conflict in DNS server settings (i.e., the laptop is set up in IPv6 with DNS servers specified onboard instead of obtaining its DNS information from the router). -
Since you have been playing around with the network settings, I suggest you make sure your DNS settings are correct for your ISP or network.
Find out from your ISP what your DNS settings are supposed to be, once you've done that, you'll need to make sure that you've entered the DNS settings properly.
You may also want to choose "Obtain DNS server address automatically" if your ISP permits it.
The problem might be related to your DNS cache, so flush it out. To flush the cache, type ipconfig /flushdns at a command prompt.
This is the reason I asked you about your ISP provider, find out if your ISP is having DNS problems, your ISP could be very well the source of the problem. So one possibility is that one of its DNS servers is experiencing down time and you're trying to access it.
BTW, 21Mbps it seems to me like unreal, I have the fastest connection, fiber and I only get 15Mbps in the DL.
Finally, "if" you know the addresses of the DNS servers, ping each of your ISP's DNS servers, and if any of them don't respond, remove them from your DNS list. Otherwise call your ISP for its address. -
Already called up the service provider for the DNS numebr but only sometimes will it work. At the moment the network settings are set to "Obtain DNS server address automatically"
I'll give what you said a try and get back to you if it doesn't work.
Also, my connection speed can vary between 14-21mbps depending on the exchange load. Some people in Australia can reach up to 24mbps. -

I still say try resetting the IP stack if all else fails.

use ipconfig /all and look at your settings. I would guess that either the DNS or gateway is wrong.
Quick test ping yahoo.com and ping 66.94.234.13
if the IP worked and named did not bad dns numbers. If the yahoo worked you dns is working and gateway. You will need to look at you FW and see if its blocking it. -
sounds like a driver or hardware issue to me. Especially since a hard reset restores your internet connection. It is possible your DNS cache can get corrupted. It's unlikely the problem, but it's worth a try I guess.
at the command prompt type
ipconfig /dnsflush
If that help, if unlikely, you can turn off dns caching by typing
net stop dnscache.
Curious. When your network stops working and you try to refresh your IP address, do you actually get a 192.x.x.x IP address or a private (169.x.x.x) address?
If it's a 192.x.x.x address, then it's your computer acting up. If it's a 169.x.x.x address, it MAY be the connection to your router. Again, either case it can come down to a driver or hardware issue. Also try reinstalling the driver.
I hope that helps. -
thanks for all the help. it seems to work but now i think it is my router that is the problem.
Today the VOIP just cut out and now can't even be used to answer phone calls, my other computers are disconnecting from the internet and a hard reset fixes the problem.
Has anyone had any experience with the Netcomm NBW9 voip modem router?
It has been giving me troubles since i got it but i thought i fixed all the problems. Guess not -
Hello! I'm new here, and I have a little problem. Ok, I can't set up my wireless connection. Windows Vista was checking solutions, and the solution was: TURN ON WIRELESS CAPABILITY. How can I do that?
-
Have you installed the drives for the wireless card?
If you have a compal based laptop, is your BT/WiFi switch off? -
Hmmm, I actually don't know. I installed my router, but drivers...I don't know. How can I check that? I turned on WI FI switch, but the LED light is not on

Which WiFi card do you have?
