Frequently unable to get an IP via DHCP with Vista

[Guest]

My Vista Ultimate laptop is unable to get an IP via DHCP frequently... both
with my home router and when on the road in hotels, coffee shops, etc. I am
certain it's not the router for multiple reasons. My router issues IPs via
DHCP to multiple clients (Windows 2003, Windows XPPro, Windows XP MCE,
Windows 2000, Sony PSP, phones, Tivos... you name it) both physical or
virtualized clients. The ~only~ one that has an issue is my Vista laptop. I
have the same problem in MANY hotels, coffee shops, etc.

I'm also fairly certain that it isn't hardware related. I ran WindowsXP on
the same laptop (Dell Latitude D820) with no problems for months before
switching to Vista. I can switch over to a virtual machine on the same laptop
running Windows 2003 and it has no problems in obtaining an IP (at home,
hotels, coffee shops). If I ever enter a static IP, it works instantly
(hotel, home, coffee shop).. problem is most places won't do this for you...
not to mention it's completely necessary.

When I run a IPCONFIG /RENEW (or release followed by renew), here's what I
get: "An error occurred while renewing interface Wireless Network Connection
: unable to contact your DHCP server. Request has timed out."

I'm lost. I'm running OneCare and have completely shut down the firewall...
but I'm lost... any ideas?

AC,
Have you tried this ?

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

Well, that KB helped, but no fix.

When I set it on my wireless NIC (along with the
DhcpConnForceBroadcastFlag=0 that was also present previously as =1), it was
able to get an IP, but not the DNS from my router (home network is setup to
use an internal DNS server that hands off unknowns to my ISP for some
internal stuff... works on all clients). Once i manually set the DNS, it
worked great (but obviously not ideal).

Unfortunately the wired NIC had no effect... kept ketting an internal
autoassigned IP (169...).

Any other ideas?

If that doesn't work, you may want to use static IP instead of DHCP.

Like I said, that works, but it completely not an option when you're in a
hotel/coffee shop. Pretty poor on Vista's if that's the only option availble
when all other clients have no problems.

I've seen multiple complaints and issues with the 3945. Sometimes a
different driver resolves issues.

Bingo... combination of the latest drivers and those two broadcast registry
tweaks fixed it for both the hardwired NIC and wireless NIC.

True test will be the hotel next week!

The good news is that with this config I was able to get an IP from the hotel
network... the bad news is that I was required to turn off my firewall to do
so... so I'm off to the OneCare forums to figure out what port is being
blocked...

I know that this wasn't the case before I made the networking registry
changes... these changed obviously opened something up because I tried
turning off the OneCare firewall off before and it didn't help.

I have the same issue running Vista Business on an HP8710w...I have made the
appropriate registry modifications according to KB928233 and also obtained
current drivers from Intel as of today.

I can set a static ip, but if I set it to DHCP, then I don't get
anything...sometimes I don't even associate with the WAPs (tried on 3
separate one so far)

Any suggestions?

same Intel 3945 wireless ? Ken from MSFT posted this the other day:

"Based on my experience, there are some issues when we resume from
sleep/hibernate on Windows Vista. This issue occurs because of the
power saving features that are included in Windows Vista. The
default power plan that Windows Vista uses for a mobile PC is the
Balanced power plan.


To work around this issue, use one of the following methods, as
appropriate for your situation.


Method 1: Connect the mobile PC to a power source
================
When you plug the mobile PC into a power source, Windows Vista
switches the wireless network adapter power setting in the default
power plan from the Medium Power Save setting to the Maximum
Performance setting. This turns off the 802.11 power save mode.
Method 2: Modify the default power saving power plan
================
Modify the default on-battery power setting for the wireless network
adapter. Configure the wireless network adapter to use the Maximum
Performance setting when Windows Vista is configured to use the
Balanced power plan or the Power saver power plan. To do this,
follow these steps:

1. Click Start, type Power Options in the Start Search box, and then
click Power Options in the Programs list.

If you are prompted for an administrator password or confirmation,
type your password or click Continue.

2. Click Change plan settings under the power plan that is selected.
For example, if the Balanced option is selected, click Change plan
settings under Balanced.

3. Click Change advanced power settings.

4. In the Power Options dialog box, expand Wireless Adapter
Settings, and then expand Power Saving Mode.

5. In the list that appears next to On battery, click Maximum
Performance, and then click OK.


Method 3: Use the "High performance" power plan
================
If the computer is running on a power plan other than the High
performance power plan when you connect to a wireless network,
manually change the power plan to High performance. To do this,
follow these steps:

1. Click Start, type Power Options in the Start Search box, and then
click Power Options in the Programs list.

If you are prompted for an administrator password or confirmation,
type your password or click Continue.

Note: You can also right-click the battery icon in the notification
area to access the Power Options command.
2. Click High performance.

For more detailed information, please refer to the following
articles: 928152: You may experience connectivity issues or

Actually, it's an Intel 4965...and I did previously come across the articles
you included below and have made the necessary power modifications to ensure
the device is not being powered off or otherwise affected by the sleep
state....though all of my troubleshooting was during an active, power
supplied session.

I have also requested the hotfix mentioned in the following MS KB article:
http://support.microsoft.com/kb/935222 and am considering employing it if I
cannot make headway through any other avenues.

If you there are any known issues with this specific intel adpater or any
other suggestions, please let me know.

Thanks...

I don't have any personal experience with the Intel draft N capable
wireless radios and I have not seen anyone posting here specifically
mentioning this hardware. You said you tried 3 WAPs. All the same
hardware/firmware? Do you have info on what these are?

http://support.us.dell.com/support/...eid=R152679&formatcnt=1&libid=0&fileid=203417

I've seen multiple complaints and issues with the 3945. Sometimes a
different driver resolves issues.

Like I said, that works, but it completely not an option when you're in a
hotel/coffee shop. Pretty poor on Vista's if that's the only option availble
when all other clients have no problems.

Ok...I have some updates, I am now able to connect to 1 of the three WAPs. I
wasn't able to try this last one until I arrived at work. So it appears one
of the changes I've made appears to have been successful with my work
WAP...which is a Cisco Aeronet 1100 Series running WPA/TKIP.

The two other WAPs I have are a SonicWall TZ170 (running the latest
firmware) and an ActionTech M1424WR (running the latest firmware)...both are
running WPA/TKIP.

If I set my wireless adapter to a static IP and create a profile for either
of these WAPs I can usually connect. However, when I set my wireless adapter
to DHCP, sometimes I cannot even associate with the AP, let alone get an
IP...but my XP laptop cannot connect to them both through DHCP with no issues
whatsoever.

The ActionTech WAP is just the standard Verizon supplied wireless router for
FIOS, but the Sonicwall is an enterprise-class wireless router, so I'm not
sure what the difference is between these other two WAPs and the Cisco
one...but apparently I'm gonna have to dig in and find out.

I have a serivce request into SonicWall for the TZ140, so we'll see if they
come back with any router settings that might need to be changed, but since
my XP laptop connects to both these WAPs successfully, it seems like there
still may something that needs set/altered in Vista as well.

Thoughts?

I don't have any personal experience with the Intel draft N capable
wireless radios and I have not seen anyone posting here specifically
mentioning this hardware. You said you tried 3 WAPs. All the same
hardware/firmware? Do you have info on what these are?

Actually, it's an Intel 4965...and I did previously come across the articles
you included below and have made the necessary power modifications to ensure
the device is not being powered off or otherwise affected by the sleep
state....though all of my troubleshooting was during an active, power
supplied session.

I have also requested the hotfix mentioned in the following MS KB article:
http://support.microsoft.com/kb/935222 and am considering employing it if I
cannot make headway through any other avenues.

If you there are any known issues with this specific intel adpater or any
other suggestions, please let me know.

Thanks...

same Intel 3945 wireless ? Ken from MSFT posted this the other day:

"Based on my experience, there are some issues when we resume from
sleep/hibernate on Windows Vista. This issue occurs because of the
power saving features that are included in Windows Vista. The
default power plan that Windows Vista uses for a mobile PC is the
Balanced power plan.


To work around this issue, use one of the following methods, as
appropriate for your situation.


Method 1: Connect the mobile PC to a power source
================
When you plug the mobile PC into a power source, Windows Vista
switches the wireless network adapter power setting in the default
power plan from the Medium Power Save setting to the Maximum
Performance setting. This turns off the 802.11 power save mode.
Method 2: Modify the default power saving power plan
================
Modify the default on-battery power setting for the wireless network
adapter. Configure the wireless network adapter to use the Maximum
Performance setting when Windows Vista is configured to use the
Balanced power plan or the Power saver power plan. To do this,
follow these steps:

1. Click Start, type Power Options in the Start Search box, and then
click Power Options in the Programs list.

If you are prompted for an administrator password or confirmation,
type your password or click Continue.

2. Click Change plan settings under the power plan that is selected.
For example, if the Balanced option is selected, click Change plan
settings under Balanced.

3. Click Change advanced power settings.

4. In the Power Options dialog box, expand Wireless Adapter
Settings, and then expand Power Saving Mode.

5. In the list that appears next to On battery, click Maximum
Performance, and then click OK.


Method 3: Use the "High performance" power plan
================
If the computer is running on a power plan other than the High
performance power plan when you connect to a wireless network,
manually change the power plan to High performance. To do this,
follow these steps:

1. Click Start, type Power Options in the Start Search box, and then
click Power Options in the Programs list.

If you are prompted for an administrator password or confirmation,
type your password or click Continue.

Note: You can also right-click the battery icon in the notification
area to access the Power Options command.
2. Click High performance.

For more detailed information, please refer to the following
articles: 928152: You may experience connectivity issues or
performance issues when you connect a mobile PC that is running
Windows Vista to a wireless access point

from hibernation, the network icon in the notification area does not
show the correct connectivity status

I have the same issue running Vista Business on an HP8710w...I have made the
appropriate registry modifications according to KB928233 and also obtained
current drivers from Intel as of today.

I can set a static ip, but if I set it to DHCP, then I don't get
anything...sometimes I don't even associate with the WAPs (tried on 3
separate one so far)

Any suggestions?

sounds like these need newer firmware than what is available if you
have tried all the other available fixes. if you disable/re-enable
the wireless NIC when these are set to DHCP and they fail, does that
make any difference?

The two other WAPs I have are a SonicWall TZ170 (running the latest
firmware) and an ActionTech M1424WR (running the latest firmware)...both are
running WPA/TKIP.

If I set my wireless adapter to a static IP and create a profile for either

I think perhaps you're right regarding the firmware of these other
WAPs...I've been able to rule out the HP/Intel hardware as the problem.

I got a 2nd hard drive for this laptop and bulit it up using XP Pro (32)
instead of Vista (64) and I can connect to all three WAPs with no issues.

So there must be some new settings in the protocol negotiation that Vista
uses...something that the Cisco WAP supports...and the other two don't...I
just wish I could isolate what that was so I'd know what function a WAP needs
to support to function with Vista.

start here

they are routers - many are switchable to AP only
