Internet Connectivity Problems
Hello, tonight I just made the wireless connection that we use security enabled. I am using a D-Link WRB-2310 wireless router and when to their website and followed the steps. I successful set up the connection and have it security enabled now. I updated each computer in the house, so that it will automatically connect to the new settings.

But now when I have been using the Internet over the past half an hour or so about half of the time I am running into a connectivity problem? When I look at the wireless connection dialog, it shows that I have a strong connection and when I try to diagnose the problem Windows can't find any errors? Any feedback or tips on how I may fix this problem would be appreciated.

can you take the secruity off again and see if that stops the problem and confirms that it is a secruity key issue

what type of key did you put on
WEP, WPA, WPA2 etc

I will also move to networking forum, where you may get more response

Well, since he was using the encrypted link for half an hour, it's hard to imagine the encryption keys suddenly became different.

When you have the problem, I'd like to see this.


Try these simple tests.

Hold the Windows key and press R, then type CMD (COMMAND for W98/WME) to open a command prompt:

In the command prompt window that opens, type type the following commands one at a time, followed by the Enter key:

NOTE: For the items below in red surrounded with < >, see comments below for the actual information content, they are value substitutions from the previous IPCONFIG command output! Do NOT type <computer_IP_address> into the command, that won't work. Also, the < and > in the text is to identify the parameters, they are also NOT used in the actual commands.

Do NOT include the <> either, they're just to identify the values for substitution.


IPCONFIG /ALL

PING <computer_IP_address>

PING <default_gateway_address>

PING <dns_servers>

PING 74.125.45.100

PING yahoo.com


Right click in the command window and choose Select All, then hit Enter to copy the contents to the clipboard.
Paste the results in a message here.

<computer_IP_address> - The IP Address of your computer, obtained from the IPCONFIG command above. (For Vista/Win7, the IPv4 Address)

<default_gateway_address> - The IP address of the Default Gateway, obtained from the IPCONFIG command above.

<dns_servers> - The IP address of the first (or only) address for DNS Servers, obtained from the IPCONFIG command above.


If you are on a machine with no network connection, use a floppy, USB disk, or a CD-RW disk to transfer a text file with the information to allow pasting it here.

During the time of this test, my connection was running at a snail like pace. It took well over 30 seconds for me to pull up the forums on TechGuy and my Gmail would only load in HTML format. Now my computer seems to have picked up its pace again. Possibly it is a problem with my ISP? I will give them a call.

Try a wired connection, if you still have slow access, then I'd like to see the following test on the wired connection.



Register at DSLReports and run their Line Quality Tests. It's best to run this test with a direct wired connection to eliminate any wireless issues from the results. It's useful many times to run this test several times, and we'd like to see each of the results. Post the results link from the top of the test display page for each test run here.

The link to post is near the top of the page and looks like:

If you wish to post this result to a forum, please copy/paste this URL
http://www.dslreports.com/linequality/nil/2357195 <- sample only, yours will obviously be different!
and your IP will be disguised.

Copy/paste that link here.

Note: You will have to enable PING (ICMP) request response either in your router (if you have one), or in your computer's firewall for direct modem connections. This is very important to get the most important part of the test to run.


DSLReports

Here's also the Line Quality Tests FAQ to help you understand the results. This will answer some questions about the line quality display.
