ok so about 2 days ago i got infected with really bad spyware/viruses or somthing (http://www.geekstogo...ng-t196458.html) and unfortunately i didnt resolve the problem in time and evytime i booted up and connected to the internet using wireless i would get disconnected and the computer would restart after about 10 min. So i decided to reinstall a fresh copy of windows vista sp1. i did this and now, i cant connect to any wireless networks. im using a modem and dial up now. i can see networks but wen i try to connect i just see "Connecting to bswee" then i see "windows cannot connect to bswee diagnose the probllem connect to a diff. network". i tried connecting to my school network same prob so it isnt my network. i reinstalled the drivers that were working before i reintalled windows, same problem. i got the updated drivers and installed those and i still cant connect. what should i do? i have an intel® pro/wireless 2200bg network connection card. i am not sure if the spyware/virus could have cased this.
oh and one more thing since i reinstalled, in devisce manager i see under other devices a mass storage controller but i already installed all the drivers and devices i have and windows cantt find what this is one the net. I'm not sure if this could cause my problem also.

Windows Vista cannot obtain an IP address from certain routers or from certain non-Microsoft DHCP servers

SYMPTOMS
Consider the following scenario:
• You connect a Windows Vista-based computer to a network.
• A router or other device that is configured as a Dynamic Host Configuration Protocol (DHCP) server is configured on the network.
• The router or the other device does not support the DHCP BROADCAST flag.
In this scenario, Windows Vista cannot obtain an IP address.

Back to the top
CAUSE
This issue occurs because of a difference in design between Windows Vista and Microsoft Windows XP Service Pack 2 (SP2). Specifically, in Windows XP SP2, 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.

RESOLUTION
Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base:
322756 (http://support.micro....com/kb/322756/) How to back up and restore the registry in Windows
To resolve this issue, disable the DHCP BROADCAST flag in Windows Vista. To do this, follow these steps:
1. Click StartStart button, type regedit in the Start Search box, and then click regedit in the Programs list.

User Account Control permission If you are prompted for an administrator password or for confirmation, type your password, or click Continue.
2. Locate and then click the following registry subkey:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\{GUID}
In this registry path, click the (GUID) subkey that corresponds to the network adapter that is connected to the network.
3. On the Edit menu, point to New, and then click DWORD (32-bit) Value.
4. In the New Value #1 box, type DhcpConnEnableBcastFlagToggle, and then press ENTER.
5. Right-click DhcpConnEnableBcastFlagToggle, and then click Modify.
6. In the Value data box, type 1, and then click OK.
7. Close Registry Editor.

MORE INFORMATION
If the router or the non-Microsoft DHCP server does not support the DHCP BROADCAST flag, you can set the following registry entry as follows:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\{GUID}

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.
