Internet connection keeps timing out

[Coolme]

Hi,

I have a problem with my internet connection as it seems to time out a couple of times every day. I reinstalled Windows XP but that did not help, I used a wifi connection, a wired one, reinstalled drivers but I don't know what's wrong. This happens while I'm browsing the internet or downloading. I connect through a Lynksys router to a cable modem and other persons on my network don't seem to have this issue. Usually I'll try repairing the connection and if that doesn't work I have to restart the system. I've disabled the LAN in the BIOS to be safe. I don't think it's the firewall either.

While trying to do a Network Diagnostics I saved this log which I'm posting here:

If anyone can send me in any direction I'd really appreaciate it.

Open a CMD window, enter ipconfig /all and post the results.
You may have an improperly configured tcp/ip stack.

The wireless configuration looks OK.
Are there other wireless signals nearby?
There are only 3 non-overlapping channels.
Interference is always an issue on the 2.4GHz band.

A ping test is not an indicator of connectivity because most network equipment is configured to ignore ICMP packets.
That said, I get a ping response from your DNS server, 212.54.40.25.

Next check the errors the protocol stack recorded.
Open a CMD window and enter netstat -es
A few errors are normal, but the number should be a very low percentage of the traffic.

Thank you ua549 for taking the time to troubleshoot this problem.

There are 4 wireless networks in my area. In my home there is only one other person who connects to the network via WiFi.

Here are the network statistic:
I hope this is readable, I wasn't able to format the results in a table.
When comparing numbers, the first one is received the second is sent.

The error counts are nominal so I don't believe you have any hardware or software issues. Check for interference. You may need to select a different channel.

Have you used a wireless packet sniffer to see what 802.11g signals and their strength are in your area that might be causing interference?
NetStumbler is an oldie but goodie tool to start with on XP as long as you nic is capable of promiscuous mode operations. (most are)

Kismet is another/newer tool with more capabilities or you can do a Google search for a tool.

[Coolme]

I have decided to change the frequency channel. I'll let you know how it goes. Strange is I lost the connection when I closed Net Stumbler.

[ua549]

That is normal because the driver was reset.

[Coolme]

Initially the channel change did not help my internet connection. I then reset the router to default, upgraded to the latest firmware and chose a channel that would not overlap with the strongest signals nearby. I think it's working now.

Thanks for the time and help ua549.
