Fujitsu Amilo , Vista HP, won't connect to wireless network.

chrisfixit used Ask the Experts™
My friend's Amilo running Vista Home Premium refuses to connect to his new router's wireless network. My Dell, sitting next to his, connects immediately, and his Amilo  connects to my wireless network at home with no problems.

Vista simply says 'Cannot connect to SAGEM123 network'.

I've tried turning off encryption but it still refuses to connect.

(I have a feeling that I've seen a similar problem and it came down to an invalid passkey being entered initially and then despite re-entering it when prompted, for some reason Vista never overwrote the incorrect key).

Any ideas please!!

If you have an Inability to Connect and the wireless doesnt receive the single try some or all of the following.

1) It could be the Wireless adapter driver issue. Upgrade the latest driver. Or use Microsoft Wireless Zero Configuration service.
2) You may need to update the software or firmware in your wireless router or access point.
3) Changing wireless networking channels.
4) Incorrect configuration. The mismatch might be in the form of different authentication settings, incompatible equipment, or other configuration issues.
5) Check access control (MAC) address filtering.
6) The wireless AP and wireless network adapter are not using the same 802.11 standard (for example, you are using an 802.11b network adapter and a 802.11a wireless AP)
7) The wireless radio button on the computer might be in the off position
8) 802.1X authentication is enabled for wireless network that does not support 802.1X authentication. You may disable 802.1X authentication.
9) The computer is running Microsoft wireless software and wireless manufacturer software.
10) Disable IPv6.
11) Disable NIC power management
12) Re-set NIC speed.
13) Radio frequency (RF) interference from nearby devices such as cordless phone and Bluetooth devices
14) Outdated wireless network adapter driver
Below is a known vista wireless issue if the above don't work.
It possible the BROADCAST flag in DHCP discovery packets is set to 0 (disabled). In Windows Vista, the BROADCAST flag in DHCP discovery packets is not disabled. Therefore, some routers and some non-Microsoft DHCP servers cannot process the DHCP discovery packets.
Disabling the DHCP BROADCAST flag in Windows Vista. To do this, follow these steps: Click Start, type regedit in the Start Search box, and then click regedit in the Programs list.
If you are prompted for an administrator password or for confirmation, type your password, or click Continue. Locate and then click the following registry subkey:
In this registry path, click the (GUID) subkey that corresponds to the network adapter that is connected to the network. On the Edit menu, point to New, and then click DWORD (32-bit) Value. In the New Value #1 box, type DhcpConnEnableBcastFlagToggle, and then press ENTER. Right-click DhcpConnEnableBcastFlagToggle, and then click Modify. In the Value data box, type 1, and then click OK. Close Registry Editor.
By setting this registry key to 1, Windows Vista will first try to obtain an IP address by using the BROADCAST flag in DHCP Discover packets. If that fails, it will try to obtain an IP address without using the BROADCAST flag in DHCP Discover packets.
If you know the router or the non-Microsoft DHCP server does not support the DHCP BROADCAST flag, you can set the following registry entry as follows instead of using the DhcpConnEnableBcastFlagToggle registry key.

Value name: DhcpConnForceBroadcastFlag
Value type: REG_DWORD
Value data: 0
Note A data value of 0 disables this registry entry. You can use this registry entry to prevent Windows Vista from using the DHCP BROADCAST flag. After you set this registry entry, Windows Vista never uses the DHCP BROADCAST flag.
Hope this helps
