Maybe you can try checking this

1- See if your PC system is set up to assign IP addresses

-Control Panel
-Click Network connections
-Right click Wireless Network->properties
-Highlight Internet Protocol (TCP/IP)-click Properties (below)

Verify buttons for Obtain IP addresses automatically (that's DHCP) and DNS
address automatically is checked off

You can check if the laptop HAS an IP address by opening up a DOS window and
typing in the command:

IPCONFIG/ALL

This will also tell you if DHCP is enabled, and/or DNS is enables. You will
not be able to go on the internet if DHCP and DNS is not enabled NO MATTER
how good your signal strength is!!

And the router has to be set to allow DHCP, and I assume its done if the
Router is configured OK, AND if your ISP confirmed that your router is OK
with their service. I had to get another router for my AOL service because
the first one would NOT work with the service.

2- When I had this problem of "little or limited" connectivity after having
the network working for a week after I got the router and wireless the USB
recevier, at least for my Linksys Router, tech support had me hit the Reset
Button on the Router, and walked the configuration through with me from
scratch, and that itself solved the problem.

The I had another eposide where I had the connectivity problem again, and I
didn't try figuring it out once again, so I just hit the reset, and that did
it. Turned out I had to do this twice in about 6 months, which isn't so bad.

I have since read that there's a cache somewhere in the router that might
not be properly cleared out.

This would be the case if you had the network working, as you mentioned, and
then it suddenly didn't work.

A LITTLE BASICS (you said you're clueless ..)

A regular PC going through a modem is like your home telephone. The phone
rings, you answer it. and speak directly with the caller.

A PC going through a router is like a small office with a switch board. The
call comes in, to ONE main number, and somehow, the call has to get routed to
an employee via an extension. In the network, all data from the ISP comes to
the router whcih then has to figure out when to sent to data, in other words,
which PC??.

There are "static IP addresses" where every employee has a fixed desk and a
fixed extension.

On the other hand, there are "dynamic" IP addresses where employees does not
have a fixed extension or desk, but has one "good for the day". In this
system someone (the operator or receptionest) has to keep track of the "cross
reference" between the employee and this ever changing extension. In the
network, this tracking is in the PC via DHCP. A cross reference exists in
the router. This is the most common scheme in home networks.

What does "signal strength" compare to. It only means there is a connection
between the switchboard and the extension, but if the "phone operator" don't
know the extension of the employee, the fact that the connection is good
means little.

In working with my ISP, AOL, the first question is if when the router
received data, does it know which PC it goes to?? Presumably, most routers
works with most ISP's in general, but not AOL.

Then, the router has to assign an IP address to the laptop when its turned
on. IN this aspect, is there a range in the router designating this?? In
other words, the swithcboard operator has to have a piece of paper by her,
big enough to list ALL the extensions, crossing referencing all the employees
at work.

What would happen if the paper has only room for six names, and ten people
are at work??

Of course, there's a bit more to this, but these are the basics.

Thanks for your input.

Here are 4 different bits of info :

1. I tried using the Toshiba laptop thru the Netgear Wireless Router
using a cable. (not wirelessly) The internet works ! So the info is
moving fine from the modem to router to my laptop via cable.


2. Then I tried repairing the wireless network...It said it could not
renew the IP address.

3. Also the wireless connection says Signal Strength : excellent BUT
Limited or no Connection. So wirelessly the same Router won't work.

No what IP is it talking about ? the laptop or Netgear Router ( Pls
note I am not technical...almost clueless !)

4. I can connect to my neighbhors wireless network .Internet works.

Can anyone pls help me now. How do I get the network to renew the IP ?

Again, pls note I am not technical...

Thanks

Hi,
Had the exact same problem-identical!!! had netgear-couldnt figure it
out. Bought linksys. dont remember much;but I'll try to help? Can you give a
little more info about the Linksys router ? I have a WRT54GX2 and can tell
you how to configure it. My laptop works great now. Had to set the channel
to 11 only-not automatic. Connect every single time now! :-) My house only
has one wireless connection-my laptop;but it fixed it. And info about your
laptop card. I have Intel Proset card and its troubleshooter works great.
Post back to this thread if you still need help.

The neighbhor's network is much further. When I am in my neighbhor's
network it says signal is low.
Yet it is very fast.

My own Netgear for the most part does not work but signal says
Excellent. I am in the next room yet it doesn't work. I am so close to
the modem and router - only 10 feet away

If I connect directly via wires to the modem the connection is good.

My question...how can the connection say signal strength : excellent
and yet I cannot connect to the internet.

What could be going on here ?

Thanks
Kim

Since the problem is with just that one laptop, it is probably the
laptop,
not the router or interference from other devices. If you have the
option,
you could try changing the channel the router is using (you'll have to
make
a corresponding change to all the other wireless devices or they won't be
able to connect). But my money is still on the laptop being the problem.

Go to the laptop vendor's web site and see if they have any driver
updates
for the wireless card in the laptop. It is also possible that a Windows
update installed a Microsoft driver for the wireless card in the laptop,
and if you just do a driver rollback, it might just fix your problem.

Let us know if you find a fix, and what it is.

Strange wireless issue .....pls help
*****************************************

1. I have a reasonably new laptop that came with a 802.11b/g and IEEE
1394, Win XP etc.

In addition, we have
a Netgear wireless Router with Comcast Motorola Modem. We have comcast
cable internet.

The wireless connection worked fine for many months but now all of a
sudden my wireless connection to "my laptop' does not work well. It is
inconsistent and sometimes just hangs.

Other wireless laptops and wireless desktops in the house get good
internet connection using our network. But with my laptop, I cannot.

My signal strength says "excellent" 54. Mbps. Yet there is no or an
inconsistent connection.
I am in the next room to the router and modem.

2. Now ... a funny thing that happens. When I click on View Wireless
Networks and choose another network in the neighborhood, I get fast
internet connection...even though it says
signal strength "very low".

3. Comcast checked the modem they say all is fine. They said the
problem could be the wireless router.

4. So I bought a new top of the line Linksys Wireless Router..about 200
Mbps.
The problem is still the same ...sometimes I get kicked out of my
wireless network and get connected to some other...all this
automatically.

I have disabled and enabled the wireless network on my laptop, turned
off and on the router and modem etc ...but nothing has helped.

If the problem was with my laptop, then how do I get good internet
connection using someone else's network ? I do not want to rely on
other people's network.

Can anyone pls help me.

I am not technical.

Thanks in advance,
Kim
