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" under administrator. All I did was ping the wireless router. Let the result speak for themselves...

Ping statistics for
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...
-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 -> before disconnect then becomes 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. (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?

    The appearance of the auto-replies feature looks slightly different in the newest versions of iOS, but the functionality remains entirely the same throughout iOS 6 and iOS 7, both in setting and using the automated canned responses.

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.

Try to Disconnect and Connect the Internet Manually in the Wireless Network Connection. Also this can be a problem with our Computer or Laptops Lan Card which may be having issues in connecting.

I have internet through Comcast and I bought a Valet to setup a P2P home network but my throughput is sluggish and my connection lags. How do I fix this?

First you need to find out the speed of your connection. If your connection speed is to slow then that could be the reason. If you have good connection speed then i would suggest getting a faster modem/router. As far as your browser crashing could be the connection speed,or you could have downloaded a virus. I would suggest investing in a good internet security/antivirus program such as Norton. hope this helps

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 Firmware. I "upgraded" to the 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! =)

Notebook won't connect to network

1) Verify if Wi-Fi WLAN interface of your notebook is OK.
1a) Check whether HW switch is ON and the wireless system service is running.
1b) Switch on the WLAN Access Point (router) SSID broadcasting.
1c) Scan WLAN networks by the notebook. Can you see your home WLAN? If not, there is HW or SW problem in your wireless adapter probably. If WLAN is visible, continue by next steps.

2) Remove all WLAN security on both sides (AP and notebook): Authentication = none/open, encrytption = none.
3) Activate DHCP server in the router and set the dynamic IP assigning on WLAN notebook interface.
4) Select your home WLAN SSID in the list and try to connect.
5) Wait and check status. Is WLAN connected? Does obtain the notebook an IP address?
6) In success case set the WLAN security.

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...
