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.

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.

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.

Did you reboot the router?

It may be something simple. Have any neighbours recently added a wireless
network? Have you installed anything that may be interfering? i.e. cordless
phone, cheap fan that generates a lot of r/f noise, fluorescent desk lamp.
etc.

I agree that power cycling clears a lot of problems and also shut down the
machines until the router is back up and steady then boot up the
computers.
With my setup it's a Wireless 4 port router with my machine connected by
ethernet to the router, XPHomeSP2. The other XPHomeSP2 is connected
through wireless and I have a WinME machine connecting through wireless.
I find if I power cycle the router without switching off the machines
first and get everything working again with regards connecting to the
internet it plays havoc with shutting the XP's down at the end of the day.

Thanks for the suggestions.

The problem PC is a desktop system (not a laptop).

The network also includes two laptops (including the one I'm typing this on)
and another desktop PC. All connect wirelessly. All work perfectly.

My problem PC was working perfectly. I did not make any network changes. I
am reluctant to stop messing about with TCP/IP settings.

My modem and router is a combined unit. I switched it off last night but the
problem persisted this morning when I tried again. I presume switching it
off is the same as a reboot. The lights on the modem/router report no
problems whatsoever and every other PC/laptop works OK.

I can't connect to my modem/router web management page so something
fundamental must be going wrong between my PC and the router.

I am going to try to re-install my wireless network adaptor software. Then I
will replace my wireless adaptor to see if that helps.
