Sudden wireless network problem

My home wireless network has worked flawlessly for months but one of my PCs
suddenly refused to work last night.

I have a BT Broadband connection (1Mb). This connection works OK since the
other PCs in my home connect OK (I am typing this from my wireless laptop).

My hardware is: BT Voyager wireless router/modem. Belkin wireless network
adapter. All running at 801g (54Mbit). I let my Belkin software manage the
connection (not Windows). I'm running Windows XP SP2.

Last night my Internet connection suddently went down. The PC was previously
working fine (and connecting to the Internet without a problem). The icon in
the system tray was reporting "limited connectivity" but I had something
else to do and ignored the problem.

But this morning the same problem arose. This time I appeared to have full
(90%) connectivity according to the icon in the system tray. So I expected
to connect to the Net without problems - but I couldn't (it timed-out).
Worse, I can't connect to my router's home page. But my PC reports that my
wireless adaptor is working OK and that I have connectivity (ranging from
90-95%). But nothing works.

Sometimes the system tray reports "limited connectivity" but if I disable
and enable the connection it goes back to (almost) full connectivity. But I
still can't "see" my wireless router (i.e. it's admin web page).

I'm at a loss. Help!

Cheers.

Could be a few things, sounds like your laptop is having diffculty
communicating with the DHCP server from the router (thats what gives it the
ip address etc).

Instead of disabling and enabling your connection, go to run type cmd and
type ipconfig /release and then ipconfig /renew see if you can
communicate....

Also, it might be worth changing the channel that your wireless adapter is
on, they usually default to 11, try a different number.....

Also try power cycling your router, most combined routers/dsl/wireless
devices have a reputation for needing to be rebooting now and then.

Firstly try to check your TCP/IP settings. Do you use DHCP ?
try:
start/run/cmd
ipconfig

If everything looking alright try to check your WEP and SNR.

If still isn't working I could propose you to check your firewalls,
antyvir softwere at your PC.

How do the other PCs connect? By wireless or by Ethernet cable? If others
connect by wireless and work OK, the problem is presumably with your laptop.

If your laptop is the only PC that's connected by wireless, it may be the
router's wireless adaptor that has got into a strange state: you coudl try
resetting the router (either from its web interface or by powering it off
for 30 seconds).

Check to see if you laptop is being given an IP address by the router's
DHCP:

- Start | Run | cmd
- At the C:> prompt in the black window, type ipconfig /all

You should see output like this



Windows IP Configuration


Host Name . . . . . . . . . . . . : MartinLaptop
Primary Dns Suffix . . . . . . . :
Node Type . . . . . . . . . . . . : Unknown
IP Routing Enabled. . . . . . . . : No
WINS Proxy Enabled. . . . . . . . : No


Ethernet adapter Wireless Network Connection:

Connection-specific DNS Suffix . :
Description . . . . . . . . . . . : NETGEAR WG111T 108Mbps Wireless
USB2.0 Adapter
Physical Address. . . . . . . . . : 00-0F-B5-3C-65-6F
Dhcp Enabled. . . . . . . . . . . : Yes
Autoconfiguration Enabled . . . . : Yes
IP Address. . . . . . . . . . . . : 192.168.0.2
Subnet Mask . . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . . . : 192.168.0.1
DHCP Server . . . . . . . . . . . : 192.168.0.1
DNS Servers . . . . . . . . . . . : 192.168.0.1
Lease Obtained. . . . . . . . . . : 13 August 2005 10:12:37
Lease Expires . . . . . . . . . . : 16 August 2005 10:12:37


The important thing is that your PC has an IP address 192.168.x.x and that
its default gateway, DNS and DHCP servers are each the IP address of the
router. Compare the output of ipconfig /all with that from another PC that
works (it doesn't matter whether it uses Ethernet or wireless): both should
have IP addresses in the same range (eg 192.168.0.2 and 192.168.0.3).

If the router has the ability to display the devices that are connected to
it, see whether the laptop and its IP are listed.


Report back the output of ipconfig and I'll see if I can diagnose further.

Hi Bobby,

Reset the router first. Shut down the router and broadband modem. Then power
up the modem and wait until it makes its connection, then power up the
router. You may also find that you need to restart the systems connected to
it, but you may get around it by running ipconfig /release, then /renew from
a cmd prompt.

there is only one combined modem/router/wireless box.

OK. Power up the combined box and everything within it will start -
hopefully in the correct order to keep Richard happy!

Hi,

Noted. Still though, power cycling is the first thing that should be done.
As it is an all-in-one unit, I would disconnect the machines from it during
this operation.

If you're using MAC address filtering, check that.

If Pac-Man affected us as kids, we'd all be running around in darkened
rooms, munching magic pills and listening to repetitive electronic
music.

sure. For info, in the UK separate ethernet ADSL modems are not very
common, and are usually a nuisance as the default DSL service is PPPoA
and not PPPoE.
