In the browser enter the address 192.168.1.1 and press enter. It will ask for ID give admin password - admin (unless you have changed it) then you will enter the router set up. Setup your computer as 192.168.1.2

I HAVE A IBM R40 WITH INTEL/R1 PRO WIRELESS LAN 2100 3B, IT CANNOT CONNECT TO MY ROUTER WITH WEP OR WPA ENCRIPTION


Check to see the wireless LAN card driver is enable and working, if not reinstall the wireless driver.
Theencryption key secures your data from unauthorized access. The router's password is a Passphrase or the WEP or WPA orWPA2 encryption key. The Passphrase generates the WEP or WPA or WPA2 encryptionkey and this is in the router's wireless settings. To connect to your wireless router, configure the router'swireless settings ie SSID, plus the WPAor WPA2 encryption key and then configure wireless cards in the laptops and orcomputers with these router's wireless settings. Then the laptops and desktopcomputers can communicate with your wireless router.

You need enable wireless in router.
Connect your router to computer with ethernet cable then you can access it with following default link.
http://192.168.1.1
or
http://192.168.0.1
If you are not able to access it with above ip then check your computers ip address gateway ip is your router ip try with it.
Then it ask for user name and password.
Type user as "admin" and password as "admin" or "password" or blank.
Then you can see configuration page of router.
Then click on wireless and enable configure it as AP mode access point mode.
Click on wireless settings then WPA Security then not down code .It is your password to connect wi fi..
Then you can connect your wi fi network with that code.
Aslo make sure WAN settings are perfect with your internet service provider.
Enable DHCP if you want ip from router.

Let me know if you need further assistance.

I cant get a wireless connection on my IBM R40 using a Linksys G


I had the same problem with my R40 (2681) and a Linksys G router. The specs on IBM's/Lenovo's site indicate that the wireless card in the R40 only handles certain types of wireless encryption. The newer types (e.g. WPA) won't work on it and they are usually the standard on routers nowadays. My Linksys G router works fine with the R40 with WEP or with no encryption. Not ideal, but that's life with an old laptop.

Wireless signal intermittent


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

Wireless shows connection,but will not connect.


This kind of problem occur due to dhcp disable in the wireless router for the security purpose. So try to give the ip adress manually by right clicking on the wireless and give the ip adress of the same range in which your network in working e.g 192.168.1.0 is the range of your ip addresses so please select the ip which is not been used by any other computer and than in default gateway enter the ip address of you wireless router and you will be able to access the internet on your system.

Ok when looking at your question i became very currious as to the answer myself so i did a litttle research and i think maybe the info on this page here: http://www.eggheadcafe.com/software/aspnet/33307589/certificate-required-to-c.aspx
could be of some use to you . even though the link describes a diferent network adapter the information there is about the same exact error on a router of the same type

I hope this information helps ... if it does not then let me know and i will find some more answers since i used to have the exact same laptop that you have now R40
