Wireless network losing internet at random intervals

[MP]

I'm not even sure I can explain this one! Be gentle with me?

I have a DLink 604+ ADSL wifi modem router. All OK on a wired LAN connection
to my PC and by wireless to two other PCs. A third has always been trouble,
losing the connection from time to time and resisting attempts to restore
it.

I have spent HOURS and HOURS on that one machine, and I can takes no more.
The present situation is that it wouldn't recognise squat today, so I
fiddled around and have got it going. All internet and mail working, but not
showing up in my wired PC's network neighbourhood. Never mind that. And
after about half an hour just sitting there, it lost all contact with the
internet. Clicking on an IE or OE page gets the white screen of 'can't find
the page' eg no connection. Rebooting usually solves until the next time.
But not always. That's when I start fiddling around and mess it up!

My contention is... if it's set up and working, how can it just stop, and
then resist every attempt to get it going again!

I have tried with WEP security and without, and I'm not sure it's a wifi
problem at all. I'm getting 70-80% signal strength and have no problems with
one of the other two machines that only gets 40-50% upstairs. This PC has
always had this problem.

I use DLink DWL120 transceivers all round, with the current drivers.

I've reloaded everything on the dam' thing from scratch, and am now at my
wits' end.

Anyone got any ideas please?!

Check your "power" settings on the problem computer to see that it matches
the other computers. Power settings can be configured in the computer cmos,
operating system, or network adapter software configuration. I have a D-link
card and when I had the card in save mode it would disconnect and not easily
connect again. I changed it to be powered on 100 percent of the time. If
possible try swapping cards with a computer that works fine to see if the
problem persists. You also may have a flaky card. I had that happen to me
once to. Good luck. I know this stuff can drive one mad. --- Steve

Good thought. I'll try that. Thanks Steve.

Mike,

This happens with DLink wifi equipment. If you update the BIOS image on the
router you will see a marked improvement in performance and connection.
You'll still, however, see this cycling in connection strength though not
usually to the point of disconnect.

If its something for business, I'd only suggest Cisco WAPs and possible
Linksys if you absolutely can't afford Cisco. For home, go with anything
but Linksys. I have seen this dozens of times with that equipment.

Sorry for the bad news.
