I'm posting this because I suffered through an increasingly bad wireless
connection for months, even though an XP machine in my house had zero
problems connecting. It would drop the connection to the Internet, then
drop the connection to my Network/Router, then connect again after a few
minutes but go agonizingly slow. Finally last weekend, it hardly
connected at all despite repeated attempts to Repair Connection, Reset
Adapter, get new IP Settings, etc.
Now that I've got it fixed, I wanted to put all the things I did into
one post in case it helps someone else.
I sifted through at least a dozen websites and ultimately I tried 11
tweaks. It's now been 8 days without a single dropout, AND my connection
speed is much faster. Here are the 11 things I gleaned from across many
sites (including this one), in the hope that these help you. I won't
describe exactly how to do each of these or why it *might* be important,
because it's covered in other posts here.
1) Change the channel on your router from 6 to 12. Ultimately, I think
this was the most important thing for my situation.
2) In your Wireless Connection Network Properties, "Networking" tab,
disable QoS Packet Scheduler. Don't need it.
3) In your Wireless Connection Network Properties, "Networking" tab,
disable Internet Protocol Version 6 (IPv6). You must leave IPv4 enabled,
you need this.
4) In your Wireless Connection Network Properties, "Networking" tab,
disable both of the LinkLayer Topolgies. Don't need it.
5) Switch the power setting on your Wireless Adapter to "Max" or
"Always On". Powering it up and down to save energy *might* cause
connection problems.
6) Disable UPnP (Universal Plug and Play) on your router. This feature
can be handy in some cases, but *might* cause connection problems.
7) Get the latest firmware from your router manufacturer's website, and
install it. Some router manufacturers have updated their router firmware
for Vista.
8) Enable "Broadcast my SSID" on your router. Some people think that
unbroadcasted SSIDs don't connect properly in Vista. A diagnostic test
on my machine flagged this too. It *might* cause connection problems.
9) Disable Wireless Security on your router. I've since turned this
back on (WPA-TKIP) with no connection problems, and it's critical to
turn this back on if you broadcast your SSID.
10) Turn off Windows Firewall. Some folks think the handling of packets
by Windows Firewall (and other firewalls) *might* cause connection
problems. I've since turned this back on just to be safe, even though
I'm behind a router.
11) Turn your Wireless Adapter's romaing tendency to "conservative" or
"minimum". Don't let it roam in "aggressive" or "maximum" or "seek best
connection" mode.
I hope this post helps you, since it took me the better part of a day
to sift many, many forum posts across multiple web sites to find all
these possible fixes.
In case any MS staffers see this post and want to know my equipment:
Dell Inspiron 530, Vista Home Premium, Core2Quad, 4GB RAM, with Broadcom
802.11g Network Adapter , LinkSys WRT54G router.
BTW, it's obvious after going through so many posts (including some
posts where MS staffers were asking questions) that Microsoft knows this
is widespread and doesn't know how to fix it yet. It's increasingly hard
to believe they didn't see this problem before they released Vista.
Good luck!!!
