Major Wireless Network Issues   Post Reply

I am working on an IBM ThinkPad R51 and recently updated the wireless driver and installed ThinkVantage Across Connections so my brother-in-law can connect to other wireless networks, other than the one at home, while he's on the road. The problem is now that ThinkVantage is there, it won't connect to the wireless network at home.

I have input the security information for my wireless network at home and it gets to the verge of connection (and a completed task for me) but it won't finish connecting due to an error with renewing the IP address configuration (the last step).

When I click on "Help Me Fix This" it takes me to a diag tool that tells me the DHCP server is not responding (Error Code: 031). I can click on a "Repair" button but that doesn't help any. I tried to repair and release the IP address via the diag tool but that didn't work either.
I know I have this option with Windows XP and that has helped in the past but not here since this is on Windows 2000.

I know the wireless network is working because I'm using it as I type on my desktop right now. The only other suggestion it gives it to contact my network administrator but that's me and up to now, everything was fine (until I started screwing around with this stupid computer).

I should also note that under ipconfig in DOS the DNS suffix is blank, the autoconfig IP address starts with 169 (which is bad, I think), the subnet mask ends in two zeroes, and the default gateway is blank.

Finally, I tried to enter the missing information (IP address, DNS server) in the settings for my home wireless network. It said it was connected but really wasn't. I have tried to repair the drivers via Add/Remove Programs to no avail.

Another attempt: I tried to renew the ipconfig via DOS but it said "the following error occurred when renewing adapter WiFi Connection: DHCP Server unreachable."

What now? Basically it stalls on "Waiting for IP configuration" when trying to connect to the network. It is @ssociated with the access point but not actually connected.

The first thing to check is the security settings on the wireless router. Not knowing which router is being used, check for the following:
1. Is WEP, WPA or WPA2 being used. Once that's determined, you'll need to have the key to input on your computer.
2. Is MAC address filtering enabled? If it is, you'll have to add the wireless MAC address of the laptop to the list.
3. Check to see if the router broadcasts the SSID. For security purposes, this should be turned off, but if you're trying to add a new wireless laptop to the router, it may need to be turned on to configure the connection (then, make sure that you turn it off after everythings working).

I have exactly the same problem but only when I switch from a wired (office) to a wireless (home) network and even then only sometimes. Occasionally I can switch with no issue and a reboot always resolves the problem, but still very annoying. I'm on an IBM ThinkPad T42.

I have WPA and MAC address filtering turned on, but configured correctly I believe because it works most of the time.

I've encountered identical issues to everyone on this thread.

Lenovo T-42 and Lenovo T-60p with Windows XP

My troubleshooting was identical to the first post.

Solution for me was when I turned off the DSL Router (doubling as the DHCP server) and back on again -- all machines started behaving again.

I did see a post on another board, that I haven't completely investigated, that pointed towards Windows Firewall needing to be unchecked within the network driver properties (Advanced Menu) -- haven't played with this to check, but thought I'd add the info.

IBM THINKPAD R51 "Make sure the network switch is on" --- Solution, the problem is your Radio is off

In ThinkVantange Access connection, Go to Tools, then Click on Find Wireless network. and it should prompt you to turn on Radio, click yes. There is another way to turn on the radio, but I'm to high to remember.
