Question about IBM ThinkPad T43 Notebook

Wireless signal intermittent

I have a D-Link DWA-3200 Wireless Gateway router using a static ip address connected to a cable modem which has the same static IP. I have 2 d-link dwa-3200 access points, one connected wired to the router and the other is on the floor above. The one on the floor above is not connected hard wired, it picks up the wireless signal. What could cause the intermittent signal that people are getting as they use the wifi? I tried switching channels, but when I unplug the cable modem, router, and two access points then reconnect them in this order: cable modem, router, then access points, it works fine for a while. I have a feeling it may be something with the amount of bandwidth - people using it. It is in a public library

    I noticed I have it under the wrong category

    How do I set one of the access points to be priority? The access points one on each floor, are set to WDS and the mac address points to the other access point. The DSA-3200 wireless public gateway is connected hard wired to one of the access points, then the other access point picks up the wireless signal, it is not hard wired.

    The computers that are losing the connection are wireless. The computers patrons use at the library connect to either the access point thats connected to the gateway router or the other access point on the main floor which uses WDS to connect to the other access point.

    I configured each of the two access points with the rogue ap and selected the other access point added it to the list. I deleted the others that came up when I hit detect. Would that help? The wireless is connected to the cable modem, giving patrons access to the internet. Our main network is static ips.

    I'm using wireless G, the router and two access points are set for mixed b/g. I have NetStumbler on one of our laptops, but I don't think I have a bandwidth monitor. What program would you recommend?

    Have to say i just downloaded the net stumbler and that is a pretty slick little program. Looks like i'm gonna have to learn how to use this one. thanks for turning me on to this one

    the first issue i see is that you are running a G network. This should work since most older laptops run G but it could still be an issue.
    To monitor the bandwidth try using something like this...

    http://sourceforge.net/projects/freemete...


    I don't have much to recommend or offer here. At work we have a fatpipe that does all this for us. But we are in the middle of trying to implement the wireless network since we are soon expanding to the third floor. The best we have got so far is running routers that have G/N networking and even still on the third floor (routers are on the forth) we have limited connectivity. In our case we know that it is limitations based on the actual building itself.

    In your case however it seems that if it is just dropping the internet and not the network connection that it is a bandwidth problem


  • Dan rogers

    Before we start digging real deep into this problem do you have a program that monitors the bandwidth usage? and are you running wireless G or N?

  • Dan rogers
    Dan rogers May 11, 2010

    Are the computers that are losing the connection wired or wireless?

  • Dan rogers
    Dan rogers May 11, 2010

    It could be the bandwith. But i am also thinking that it is switching the connection to the rouuters. Can you set one of them to be priority?

First make sure you have the latest update for your bios and wireless device, your os is probably non preload so clean any access connections utility provided by ibm, rather than using the ibm thinkvantage access connection make sure to use the windows own utility to control the wireless device

My Acer Aspire One D255-2256 netbook is having trouble connecting to the internet.


Start-Programs-Accessories-Command Prompt. Command prompt will open. Looks like a black screen. Type ipconfig then hit the enter key.
5th line down, you'll see something like this and so on.
IPv4 Address. . . . . . . . . .192.168.0.???
Subnet Mask. . . . . . . . . .255.255.255.0
Default Gateway . . . . . . . .192.168.0.1
These ip addresses may be different depending on what router or modem you're using. But if you're connected to the modem/router, you should get an ip address(IPv4 Address) and a default gateway that are the same except for the last set of numbers.See question marks above. If it's not the same then you are not connected to the router/modem. Check your wireless connection to see if it's on. Make sure you are connecting to your network. Make sure wireless signal is being transmitted from router.
See if you can hit the router if you have connectivity. Open your IE or Firefox and type only the IP address, meaning remove the http://www. Not needed. The IP address is the Default Gateway thst was listed in the Command Prompt. If you can hit the router/modem, then make sure that there is connectivity to the host. If you're DSL, you'll be using PPOE which is Username and Passwrd. Make sure you are connected by clicking connect under connection summary. If cable modem, make sure that the lights are on showing connectivity. Here's a starting point. I now need more info. If this doesn't help, tell me what you did find out and we'll go from there.

My laptop is conecting but says limited or no connectivity but I have a strong wifi signal


Hi there,
Did a bit of research for you on this and came across a ten step set of instructions which should hopefully correct, or at least narrow down your problem:
Determine whether your network access is functioning properly (that you can reach local network resources and the Internet). If you are using a broadband Internet and Windows XP Service Pack 2, this message is often a false error report. See Microsoft Knowledge Base article 892896 for details on how to work around this error appropriately.
If your network access is non-functional. continue to the following steps.
If your computer connects to the network through a broadband router , resetting (powering off and on) the router may resolve the issue. If not using a broadband router, or if resetting your router only temporarily resolves the issue and the error message re-appears later, continue to the following steps.
If connecting to your network using Wi-Fi and using wireless security, your WEP or other security key may not be set properly. Check the wireless security configuration on your computer's network adapter and update if it necessary.
If connecting to your network using an Ethernet cable, your cable may have failed. Temporarily replace your network cable with a new one to determine whether this resolves the issue.
If using a broadband router and DHCP on your network, check your computer's IP address to verify it is valid and not a private address that starts with 169.254. An invalid address of the form 169.254.x.x signifies your computer's inability to obtain a usable IP address from your router.
To resolve DHCP configuration problems, proceed to the following steps.
Reboot your computer, router (if present) and broadband modem together, then re-test your connection.
If your connection remains non-functional, run the Windows Network Repair utility on your computer.
If your connection remains non-functional, update your router settings to change from dynamic to static IP address configuration, and set an IP address on the computer appropriately.
If your connection remains non-functional, unplug your router and connect the computer directly to your broadband modem. If this configuration is functional, contact the manufacturer of your router for additional support.
If your computer is connecting to your network directly through a broadband modem, or if your Internet access remains non-functional after following the instructions above, contact your Internet provider for support.

Acquiring IP address and won't connect to wireless


You possibly have your router password protected or have changed the password recently. If you have done either, you will need access the router by the router IP address, then go in and make sure the password you have on the router is the same as the password you have no the computer.

Secondly, make sure that the router is broadcasting correctly. Hard wire(hook the computer directly to the router with a ethernet cable) to see if there is an internet connection flowing thru the router.

Third, ensure that the ethernet cord from your modem to your router is a good cord. Be sure to plug the ethernet cord from your modem directly into your computer to ensure there is a good connection as well.

Reconnect all (modem, router, and computer)

Fourth, power down router, modem, and computer together. Power up the modem first and let all the lights come on. This will renew the connection and refresh the IP address. Once the modem is up, then power up the router til all the lights are powered on the router. Lastly, power up the computer to the desktop and attempt to launch a web browser (internet explorer, mozilla, safari, etc.).

If nothing at this point works, you will have to consult your router manufacturer or a local computer repair shop. Be sure that the technicians working on your issue is certified.

How do you repair an IP address conflict? I have a wireless network system in my house along with a wireless printer. The IP address on the printer keeps changing and we're either loosing our connection to...


You can assign the xxx number as you wanted if your printer is wireless. For example your Lap top wireless is 10.0.0.3 then set your IP address for your printer is 10.0.0.xxx ( 10.0.0.9) The xxx number can't be the same with any number for any other lap top you have around the house. You can right click on Printer property to go to add Port and put this number in.

My AMD Athlon(tm) X2 Dual-Core QL-64 by Gateway has wireless network problems. When on wireless, there are lag spikes (meaning it suddenly stops working) every five seconds for around one second each time...


"under the same modem" .. you mean connected to the same router?
if you are using an external USB modem, try a different cable -and keep it short. I can't think right now of any clear causes of this problem other than a bad USB (or too long) cable (which can cause exactly this problem).

possibilities.. could be a cordless phone, cellular, wireless mouse/headphones/controller, bluetooth .. many of these devices connect with their receiver regularly and use almost identical fequencies which interfere.

Doubt it is a network conflict -where someone else has the same IP address. You could try setting a manual IP address too..

good luck!

Wireless internet on laptop


You need an external WIRELESS ROUTER or MODEM ( provided by AT&T ). After this AT&T router configuration you needs to do configuration at your laptop using CONNECTION SETUP wizard for Wireless Networks & Devices.
Then you can set IP addresses & then you will be connected to it. I hope above steps will help you.

My router wont configure


Plug in the laptop to the router and the router to the modem. Power cycle the modem. Turn on power to the router. Copen a command prompt on the laptop and type 'ipconfig /all' and press Enter. Look for your IP address (should have been assigned by the router and should look like 192.168.1.x). Also look for the default gateway. It will probably be 192.168.1.1. If that is the case, you should be able to use your web browser to connect to the router to check its configuration and the WAN status by typing in the address 'http://192.168.1.1' (or whatever was displayed for the default gateway previously.

Wireless internet connection


You haven't specified if the host computer is able to access the internet. Ip Address confict can be one of the reasons why the laptop isnt able to connect and we can have a series of reasons why we have this IP Address conflict - 1) There is no wireless encryption defined. So, we have neighbors connecting to the wireless network causing IP Address conflicts. 2) The laptop is not able to renew the IP Address after the lease expires. This can mostly be resolved by restarting the computer and in certain cases flusing the TCP/IP stack. 3) There is a static IP Address assigned to the laptop in the router's DHCP range which is conflicting with the host computer. I would suggest you may initiate a chat with me or anyone else who has expertise in routers to get this successfully resolved. That would definitely save your time. Good luck
