IBM Thinkpad, Can't connect to the internet

I don't know what to do anymore. I received this new IBM Thinkpad from my work and I can not connect to the internet at home. I am fairly proficient with networking and such, but just can't figure it out. I have a linksys wireless router that is giving out dynamic ip addresses. When I turn my computer on it recognizes the router, but I can't even connect to the router's homepage via an internal ip.

I have even tried modifying my tcp/ip setting to resolve the static ip I have with my service provider dsl extreme. This didn't work either. My computer recognizes a connection but doesn't connect. I don't know what to do. Any suggestions would be great.

I am on Windows XP, with an IBM Thinkpad Type 2373.

I know the connection works because I have a Tosiba Tecra and a Sony Vaio that both connect without a problem.

Go to Control panel and right click on the connection that u using. And click properties, and highlight the TCP/IP and click on properties. And Select the options; Obtain an IP address automatically and Obtain DNS server address automatically. And you have to check for your IE setting.
And check it out: go to Internet Option and Connection Tab and click LAN Settings and Select the check box: Automatically detect settings.
And if u still can’t connect the internet use the following commands:
Go to Start and Run and type cmd and u will get the command prompt window.
And use this command to release the IP “ipconfig/release”
And for renew the IP “ipconfig/renew”.
Please do release the IP and renew IP.
If u still can’t get the connection, and just let me know. As long as I can, I will post some suggestion that base on my experience.
I Hope that will help u to get your connection.

Is the router b or g? If it is a g router is is backward compatible to wireless wireless b?  If I am correct I believe that model IBM has a built in 801.11b wireless card in it.

Sounds like what you are saying is your laptop doesnt connect either by the LAN port OR the Wireless - is this right? You may have some firewall software installed preventing comms like ZoneAlarm which by default blocks everything. Check your Add/Remove programmes for firewall software.
If the laptop is from your work, maybe it is protected against accessing the net from outside your workplace. Check this with your IT dept.

Sounds like your work doesnt want your laptop connected except through them!!!

Michael Owen,
I have done all of the things you have recommended with the exception of ipconfig/release and ipconfig/renew. I rebooted numerous times in my trial and error process so the ip was released and renewed continually, but I I will try what you outline exactly. Can't hurt.

Soulja,
The routher is a "b" router, The IBM thinkpad has a built in a/b/g network card.

Polizat,
That is what I thought, but I have spoken with the IT department and they are as baffled as I am. I work in the IT department on the web side, so I am fairly confident that they are not trying to lead me down the wrong path.

Dear Rpallares,

R u able to ping locally? Using
ping 127.0.0.1
As long as u can ping locally thats mean ur network card got no problem.
And if u got the driver for ur network card, you may try to uninstall ur network card and scan new hardware and install the driver it again.
May be you can try to download the latest update from IBM website for ur driver.
I have been b4, the driver come with it doesnt work, so i have to go and download the lastest one from the web.
I hope that will help u
Hope to hear good news from u.

I cannot ping locally. I get "Request timed out."

I would think it could be a driver issue, but it works at my work. I just don't understand. I'm going to be troubleshooting for the next few hours. Any thoughts, please share.

So,
If u cannot ping locally, that mean ur network card problem.
Please check it out your network card, reinstall it again, if stil cannot, try to reinstall the TCP/IP.
Hope you can get it back the normal

rpallares - check to make sure your LAN adapter is not "bridged" with your Wireless adapter. With two connections sometimes you can accidentally set up a bridge and this will not allow broadcasts (ie dhcp) to pass over it. Try manually inserting the IP address you get when you plug in the other PCS you have (leave the other PC in and see if you get an IP address conflict message)

I've figured this out. It was due to MS Proxy Server software that ws installed on my machine. I removed the application and everything worked from then on.
