Dell XPS M1530 internet connection problem

Ok i hope i have the right part of the forum. The problem is every now and then while im on the internet my connection goes down and says limited connection, so im prevented from doing almost everything. Now i know you may be thinking its just your internet connection, well its not. We have two laptops and on the other one at the exact same time the connection is perfect and the lights are still shining on the wireless box. Its just a bit annoying when im doing work/surfing the inetrnet etc to get disconnected and have to restart my laptop again to reconnect...

So does anyone know whats going on? If you do how could i prevent this from happening?

Thanks.

 

It is not likely your computer. Check if you are being assigned an IP address, or check if your security key is correct if you have security enabled. My guess is that you've got all of your IPs leased out so this computer isn't getting one, I've seen it many times before.

 

Well we have only used this connection on two computers cant be leased out.

 

Try repairing or assigning your computer a specific IP (maybe its conflicting), and restart

 

Try to connect your laptop on a wired connection and see if it gets an IP from your router. Next try to shutdown the other laptops then reset your router and try to connect with just your laptop by wireless. If not then try what badhairdude had said and assign an specific IP for your laptop.

If that didn't work try to uninstall and then reinstall your wireless card. also check to see that your firewall is not preventing you from connecting to your router.

Goodluck!

 

Something else to check...

Go to Control Panel--Network Connections. Right click on Wireless Network Connection and bring up Properties. In the little box that shows what card you're using (mine says Dell wireless minicard), click on CONFIGURE. Go to the last tab that says "Power Management." Make sure the little box that says "Allow the computer to turn off this device to save power" is NOT checked. Hit okay.

I hava my XPS M1530 with these specifications:
Intel Core 2 Duo T7500 (2.2GHz, 4MB L2)
Vista Home Premium
2GB RAM
160GB 5400rpm HD
128MB 8400GT
I can not connect to internet with 56k Modem (External modem).
I encounter with the massage as follows:
Your computer can not communicate with DNS Server.
I was thinking that the problem is related to my ISP Server but I have used from 3 ISP's and this problem still exists. I can connect to internet but in limited connectivity mode and the received packets in local area connection status is less than 1000???????
I changed my phone line but the problem still exists.
Please help me to solve this problem.
What should I do?

 

I think that is not a hardware problem but has something to do with Vista. I remember my bro's HP having the same situation as you. I can't recall how I did it but it has something to do with Vista firewall or security settings. I'll try to recreate it and then i'll get back to you.

Can you also tell us about how you set it up? Firewall Antivirus that you use? Did you try connecting it via wired LAN?

 

I am using a Dial up modem with Trend Micro PC Cilin (The default Antivirus)
When I was tested my modem for the first time, I could easily connect to internet but after that I encountered with that problem.
thank's a lot if you could help me.

 

Assuming you're using vista:

Start > Right Click: Network > Properties > Manage Network Connections (Left Panel) > Right Click: Wireless Network Connection > Properties > Select: Internet Protocol Version 4 (TCP/IPv4) (If you're using IPv6 -- doubtful -- select Internet Protocol Version 6) > Properties > Select: Use The Following IP Address

IP Address: IP for your system to use. This will usually be in the format 192.168.1.x. There is a setting somewhere in your wireless configuration that will allow you to see and change the IP range. You want your computer to be in that range.
Subnet Mask: Usually 255.255.255.0, can be found in your wireless settings page
Default Gateway: Your router's IP on the network, usually 192.168.1.1

You will also find DNS information on the bottom which may sometimes be your router's IP, or your ISP's DNS server. You can talk with your ISP or google around and probably find that information.

 

The code of error that I see is:

The Computer can not communicate with DNS server (212.6.32.5)

I am using from one external modem with dial up connection. (no Wireless)
Thank's alot for your helping
