Vista - Limited connectivity for my Internet connection –Sleep mode.

Actually my Internet connection works great… at least for as long as I boot
my computer fresh. For as long as I’m doing that I have no problems. No
disconnections, no freezes, nothing. Zero problems. But, my Internet
connection gives me a warning saying that I have “Limited connectivity�
whenever I wake up the computer from the sleep mode. After that, I have no
Internet access. Besides that, the sleep mode seems to be working just fine.

The only way I can revive my Internet connection is to use the “repair
feature� or to reboot the computer afresh.

I tried making the NIC adapter not to be powered off on sleep mode and, at
the same time, leaving IPv4 as the only protocol available for my
connection. But this hasn’t worked either, whenever I returned to my
computer and I woke up my computer the connection was limited (inoperable)
again.

I really don’t know what to do. I will certainly appreciate any advice or
tips that you guys can give me!

Here below I try to resume all the characteristics of my computer. I’m sure
I’ll miss something so, please, ask me for more details as needed.

I’m Running MS Windows Vista Home Basic (localized in Spanish… I wanted to
buy it in English but the local MS doesn’t have it available for sale). All
updates from Windows Update installed.

MOBO is Asus P5KPL-AM SE with the most up-to-date BIOS and drivers that can
be found on the ASUS website.

The network adapter (LAN) is embedded in the MOBO. It’s a Realtek RTL810EL,
10/100. The driver says: Realtek PCIe FE Family Controller. Dated:
05/04/2009 Version: 6.222.504.2009

I connect to the Internet through my ISP which works over WiMAX. The brand
of their equipment (their anteanna and the powered apparatus –IDU- near the
computer) is branded Alvarion. My computer is plugged straight to that WiMAX
IDU apparatus by means of an Ethernet cable. There’s no such thing as a
router or switch and I only own a single computer.

The current protocols used for my ISP connection are: Microsoft networks,
QoS, Share printers and files, IPv6, IPv4, I/O, and another protocol that
lets other computers detect my system on the net. My excuses for not using
the proper names for those protocols as I’m translating their names to
English the best I can.

My computer has various software including: Office 2007 Home EN, Photoshop
Elements 7 EN, Acrobat Reader EN, various Live programs like the Messenger,
the software included with an all-in-one HP printer ES, Cyberpower Power
Panel (SAI) ES, Sony camera software EN, Nokia phone software EN, a DivX
official codec, Avast (free) antivirus, Google Earth, and that should be
pretty much everything I have installed—it’s my understanding that I have
the most recent updates installed for everything.

I do not tend to install software “just to give it a try� and I also try
obtaining everything from sources I can trust like the official websites. My
computer is rather new—it’s just a few months old. Both, Avast free and
OneCare online did not report any infection in my computer.

Hi
Some cards have configuration entry to wake them up with any traffic set it
so.
If yours does not have such configuration, then try to get the card out of
the Power saving mode,. I.e. configure the card not to save Power.
Depending on the OS and the computer, these configurations can be in the
Card's drivers and or the OS power saving setting.

Thanks for writing back, Jack!

While I do not see an entry for waking the comuter up with any traffic on
the device tab there's a setting called "boot ROM" on the BIOS. Is that what
you are referring to?

Every time this happens I can see on the Windows Vista Home Basic System
log:

--
Your computer was not able to renew its address from the network (from the
DHCP Server) for the Network Card with network address 00248CD89F73. The
following error occurred: The semaphore timeout period has expired.. Your
computer will continue to try and obtain an address on its own from the
network address (DHCP) server.

I've disabled the "turn off this device" in the Power Management tab of the
NIC card. But this doesn't seem to solve this problem.

The "Internet modem" has a few leds. One of them is on whenever there's a
connection between that modem and the computer. That let is always on even
when I shut down the computer, but that very same let turns off if I put the
computer to sleep. That led goes off even when I uncheck the "turn off this
device" on the Power Management tab for the NIC card. Also, There are no
warnings on the device manager panel.

Should I look for something specific in the advanced options for the NIC
card?

After I click repair this connection I got this problem: "Cannot connect to
the DNS (xxx.xxx.xxx.xxx) server". Then, after clicking repair again the
problem is solved. I have to do this every time I wake up the computer from
the sleep mode (S3) in order to regain Internet access.

On the energy saving settings of Vista there's a setting for the PCIe cards.
While my NIC card is embedded in the motherboard it's listed as an PCIe on
the NIC description. Should I turn that setting from "maximum savings" to
"Deactivate" (deactivate power savings for this device)?

I've been trying to figure up what's going wrong with my Internet connection
and I ended up with the following:

My Internet connection works great if I'm on a fresh boot up or I click the
repair option after waking up from the sleep mode (S3). Sometimes, mostly if
I wake up the computer shortly after entering the sleep mode the Internet
connection restablishes by itself.

After leaving the computer sleeping for like 30min I woke it up and, as
expected, I had no Internet acess.

I clicked the diagnose and repair option where I got that the system "cannot
connect with dns server".

Then, I opened a DOS window as an admin where I used the command: ipconfig
/renew. That command reported and error: <<Cannot establish connection with
the DHCP server. Time out.>>

I don't know if this has anything to do with the whole thing but under
"Share and detect" I have Detect Networks deactivated.

I click "Customize" for this connection in Network Center where I have it
set up as a "Public network" (as opposed to private network). Should I set
this connection to Private without fearing an Internet intrusion of sorts?

Some aditional information regarding this issue:

This is what usually happens after I wake up my computer (Vista) from the
sleep mode (S3):

I can see there's a link bewteen the computer and the "Internet modem" under
Network Map. But that very same map has a red cross between the "Internet
modem" and the Internet earth globe.

Clicking Diagnose and Repair gave me this error: cannot communicate with the
dns server.

DNS information, the IP, etc all seem to have correct values, but Vista
refuses to connect to the Internet...

This never happens when I boot or reboot the computer.

Have you installed Service Pack 2 yet? It fixes some network wake from
sleep problems.

Yes, Sir!

I have the SP2 installed together will all the other updates from Windows
Update--I have it set as it came from the factory. That's it installs all
the updates available automatically.

Thank you for your advice!

In this case, you should contact your WiMAX provider, or directly Alvarion
support.
Vista indeed had some issues with connectivity after wakeup, but all known
issues
of this kind have been fixed by SP2.
