Re: Wireless Laptop connections dropping intermittently

thanks for the response. Unfortunately, I've actually removed everything,
i.e. all forms of security entirely, and still have the same issue.

one thing that has occured to me is that it hasn't happened the entire
time
I've had the computers. I haven't installed any programs, but I have
Windows
update set to automatically install updates, and the network drops began
happening really badly about a week ago. Before, it was EXTREMELY rare,
and
in fact, I was quite pleased as I couldn't figure out what other people
were
having such problems with, but now, it's quite obvious, as the systems
lose
their internet connection constantly

I appreciate your response. Please see inline. This is now the 3rd
(EDIT -
4TH, I am cutting/pasting my responses before hitting "POST" now!) time
I'm
trying to type my response in, because my connection keeps dropping.

Hi
You state that the Internet drops but you are connected.
When this happen, as a first step, try to connect to the Router's menu
by
typing the Router's core IP to the browser.

not an issue. That's how I made most of the changes I mentioned below.
I'm
looking at it right now, in fact.

If you can Not see the Router's menus it means that it is Not an
Internet
problem but that the Connection is lost between the computer and the
Router.
If so then take all the Laptops to the same room with the Router,
disable
temp. the security, and see how the computers behave under such
conditions.

I have already done so. I disabled all forms of security, Windows-native
and 3rd party. I also disabled all forms of security with the router
(i.e.
WEP and WPA and went "unsecure") as well.

BTW. I'm not familiar with the SRX200, some old Routers have problem
providing IP via DHCP to Vista (check Linksys' support).

I guess you'd have to define "old" to me, as I purchased this router
within
the last 6 months from BestBuy.

It's basically a "faster" version of the LinkSys WRT54G routers. It's
technical designation is WRT54GX2

I have a WRT54G (without the SRX200 speed upgrade) and the same thing
happens with intermittent connection issues. It actually does enhance the
distance and speed of my XP laptop wireless connection :D

Anyway, this is driving me crazy. Let's see if 4th time posting is a
charm.
Just pinged the router from a cmd prompt, should be good, lesse!

I have 4 laptops connected wirelessly to a cable modem router.
All of the Laptops are Vista Premium (SP1). One of the laptops is a
Toshiba
P200 with an Intel 4965AGN adapter. The other 3 are Acer Extensa
5420s
running Vista SP1 with a Broadcom 802.11g adapter. The router is a
LinkSys
SRX200.

The problem is that the wireless connections will drop from the
internet
at
random intervals for random times, for no apparent reason. 2 of the
Acers
are in the same room as the Toshiba, and just because 1 is not able
to
connect doesn't mean they all are disconnected. Sometimes 1 will
lose
connection to the internet, sometimes they all will, sometimes all of
them
will be down while the Acer on the other side of the house is fine.

The network icon shows that the connection exists, just that it can't
connect to the internet. Rebooting and/or power cycling the router
doesn't
help. ipconfig /release and /renew doesn't work. Rebooting the
computer
doesn't work. Simple "diagnose/repair" doesn't work. Hardwiring into
the
router solves the problem entirely, and the lone XP computer I have
is
solid
as a rock with no network connectivity issues. Oftentimes, the
computers
will just "magically connect", usually after I get annoyed with them.
I have a 5.8 GHz wireless phone, but phone calls have no bearing on
my
internet connection (yes, I've tested it). Signal strength is
irrelevant,
as
the computer can have all bars (a few feet away from the router), 3
or 4
bars
when it's on the other side of the house, or 1 bar across my yard
(yes,
I've
tried it), and regardless of the bars, it may (or may not!) bug out
on the
internet while maintaining signal strength and showing that
connection is
maintained.

What I've done
1) Updated all firmware for adapters and router (as well as the
associated
drivers after fully uninstalling them)
2) Set MTU to 1492, set router channel to 1, 6, 9, 11, and auto
3) Ensured all laptops are set up to use maximum performance
regardless if
it's running off the battery or plugged in
4) Adjusted MAC cloning, set router network mode to G-only as well as
trying
mixed mode
5) Disabled all security settings on all computers (i.e. turned off
all
firewalls, AV, antispy in software and in hardware
6) In the middle of the boonies, so no other networks to interfere
and no
users around that might catch my router's wireless output
7) Repaired and reset winsock as well as the IP stack

After searching the internet, there are tons of people with the same
problem
and we all share a few things in common

1) Our Vista systems have issues, our XP systems don't
2) We all will drop internet despite being connected to the network
3) We have NO problems after hardwiring into the router
4) We all can connect initially, and then have our internet
connection
drop
without warning and then re-connect without warning

I'd be very interested in hearing if MS has figured out what the
problem
is.
