Question about Linksys WRT300N Wireless Router

1 Answer

WLAN having consistant high latency with frequent all-out fail

My previous problem started with a wireless N router that would crash when more than 3 computers were wirelessly connected. Just purchased a new and better wireless G netgear router that works like a charm, for all 6 other XP computers except my vista machine. This shows that it's not a network or a router problem, but it's infact this machine I am on. Ran a few simple troubleshooting tricks but the one through cmd.exe says all I need to say. Just ran a simple command; "ping -t 192.168.1.1" under administrator. All I did was ping the wireless router. Let the result speak for themselves...

Ping statistics for 192.168.1.1:
Packets: Sent = 614, Received = 493, Lost = 121 (19% loss),
Approximate round trip times in milli-seconds:
Minimum = 1ms, Maximum = 3991ms, Average = 614ms

In reading other threads I need to mention that this is NOT THE LAG SPIKE ISSUE in most vista machines, caused by the maching looking for a better signal every 60 seconds.
Here's a list of things that I have triple checked...
-Firmware
-Drivers
-Hardware drivers
-Dhcp flagging
-CPU (ping command was ran while system was idle)
-Ipv6, network discovery and media sharing are OFF
-No lightning storm =)

Is there a known virus that causes this? Reminder, I've done enough troubleshooting to ensure that this is my individual Vista home 32-bit machine that has the issue. Every other maching was returning a ping response in <1ms and mine were averaging almost 600ms.

And there have been moments when both my CPU cores would spike to 100%, sound and mouse movement become choppy, then complete disconnect. I have to reset my wireless switch on/off to regain connection.///// It's also worth mentioning that every time this happens, my new ip address will be a higher number.\\\\\ EG -> 192.168.1.8 before disconnect then becomes 192.168.1.9 after hardware reset. Im at .14 now.

    Thanks for spending the time to help me on this issue. Here are the specs you asked for...
    -Vista Home Premium SP1 32-bit on a Lenovo machine, similar to IBM Thinkpads
    -Intel dual core processor at 1.6 GHz each
    -2 Gigs of Ram
    -Broadcom 802.11g Network Adapter with latest drivers, v.4.82.28.56 (ran driver update several times a few seconds ago to make sure)

    Since my original post I have found that it is not a OS incompatibility between router and machine since the LAN wired connection works flawlessly (consistently less that 1ms ping respond time with router). However, I have not tried this machine's wireless connection at a random WiFi spot, such as the library or a Starbucks, i should do this next. And also, the incrementing IP addresses was just a configuration of the router, we can ignore that event.

    I also tried using a USB wireless device. This works perfectly...until a security build in vista was disabling my hardware. Here's the Event Viewer's Log...
    "TCP/IP has reached the security limit imposed on the number of concurrent TCP connect attempts."
    I am not posting this as another problem I need to fix, it's not the focus right now. Just saying that as an alternative the wireless USB device is just not dependable.

    I really am starting to fear that it really is my hardware going out.

    Yeah - you're response times are really through the roof.
    Can you give me details on your Vista machine?
    CPU, RAM?
    (Just the info you get when you open right-click "My Computer>Properties"?)
    Which network adapter are you using on this machine?

I would suggest borrowing a different known working wireless adapter, and test trying that. Or test using a wired connection, just to prove it is the adapter. Perhaps the wireless adapter you are using is flaky.

Enabling Wireless security on Linksys routers.....


Encrypting the network blocks any unauthorized computer from accessing the network and using its broadband connection. To enable WEP on the router,

1. Open your default browser and enter the following IP address into the address bar: <http://192.168.1.1>
2. When prompted for a username and password type “admin” on password, unless you have previously changed the password of the router, and hit OK. This will bring you to the Setup page of the router.
3. Depending on the firmware of the router. Click on the WEP Key Settings button. Or you can click the Wireless tab and select Wireless Security. Or you can click the Security Tab and select Wireless.
4. From the WEP/Security Settings window, you may enable 64 or 128 bit WEP then enter your Password on the Passphrase field and click on Generate. Make sure to copy the characters on Key 1-4 on a piece of paper before you hit APPLY. You will be needing this once you enable WEP on the wireless PC’s. Also take note that if you enable 64 or 128 bit on the router, this should be the same WEP level that you will enable on the wireless cards.

To put in the network key in your wireless adapter follow the steps below:

WEP Encryption XP's Wireless Zero Configuration ( Advisable for XP PC's )

1. Go to start>Control Panel>Network Connections>Right click on the Wireless connection then click on Properties>Click on the Wireless Networks Tab
2. From the Wireless Network Connection properties window, under the Preferred network click on Add then type your SSID on the SSID field and check the box for Data Encryption then then unchecked “The Key is provided for me Automatically”
3. Type your WEP Keys on both the Network Key and Confirm Network Key field. (This set of characters should be identical to the WEP Keys Settings on the router. For 64-bit WEP you should have 10 characters, for 128-bit you should type in 26 characters.) Then hit OK and then OK again.
4. After hitting OK a pop-up should appear on the lower right hand side saying “Connected”. Try pointing your mouse arrow on the lower double monitor icon.
5. Restart your PC

WEP Encryption using the Linksys WLAN Utility ( 98/Me/2000 )

Make sure that the WLAN utility of the Linksys adapter is already is installed. If not, you may follow follow the procedures below for "Installing the Linksys WLAN Utility"

2. On the lower right-hand side of your screen, double click on the Linksys Icon. This will bring up the WLAN Configuration Utility.
3. Click on the Profiles Tab. Make sure that the SSID that is set to default is your routers SSID. Highlight Default then hit Edit.
4. Select Profile Wizard. Continue to click the Next button, until you get to the Security Settings Window.

OR select Expert Mode then Next. Then click on Security Settings
5. Set the same WEP level that you have enabled on the router. ( ex. 64 or 128 )

MY WNR2000 router has High latency and very slow throughput. I have not been able to isloate the problem. I tried to connect directly to my modem that my ISP provided and i was getting excellent throughput...


I also had this problem when I was using the 1.2.0.8 Firmware. I "upgraded" to the 1.2.3.7. Doing so solved the latency issue, but has provided me with a whole new batch of connection problems (dropping connection randomly).

Hi, I have a dlink DSL-G604T router, wlan light not on.


Hello there!

Only thing that can cause your wlan light not working consistantly or with some blinks (which is normal thing) is bad lan cable which leads from your ADSL modem to your wlan entrance on your wireless router, please check that cable in order to fix that problem. Cable doesnt need to be coaxial so it can have 2 different lan sets (2 poles of exits male and female exit). Thats it ! =)

Please rate solution! =)

How to create games on Starcraft when I have high latency?


Just a note, you don't have high latency its just the server thinks you have high latency because its pinging you and your not pinging back because your ports aren't forwarded. The site linked below will guide you through the forwarding process, but please note! You can only host on one computer in your network, the reason for this is you can only port forward any port to one computer in your network.

It is important to follow everything this guide says for your port forwarding to be successful.
Please follow the guide on this site right here

Frequent disconnects


If the Xbox is connected wirelessly through a computer

ie. Bridge?

Then the problem would be with Windows XP, the Operating system scans every 2min's or so for new networks and at this point you will notice a "lag" or disconnect if it is bad enough.

XP: your going to have to turn off the Wireless service via msconfig.

Vista: Download WLAN Optimizer, easy fix there...
